1 General Information
The Occupant Protection System (OPS) is designed to restrain and protect occupants of the vehicle duri ng a collision.
This is achieved by the use of:
lap-sash inertia reel seatbelt assemblies fitted in all seating positions,
front seatbelt pretensioners incorpor ated in the front driver and passenger seatbelt buckle,
a steering wheel inflatable restraint (also known as a driver airb ag) for the driver,
an instrument panel inflatable restraint (also known as a passenger airbag), where fitted, for the front passenger,
and
a side impact inflatable restraint (also known as a side airbag), where fitted, for the driver and front passenger.
Some models are also fitted with active head restraints that are incorporated in the front seat assemblies. For further
information on active head restraints refer to Section 1A7 Seat Assemblies.
Locking of the inertia reel seatbelts is automatic. Deployment of the seatbelt pretensioners and inflatable restraints is
controlled by a sensing diag nostic module (SDM), which is mounted on the floor pa nel beneath the centre console. The
SDM incorporates a frontal collision sensor, while side impact sensor assemblies fitted to each si de of the vehicle detect
side impacts.
Inflatable restraints do not provide
protection to the occupants on their own
and must be used in conjunction with
seatbelts.
The rear seat is the safest place for
children.
Never fit a rear facing child seat in a front
seat.

1.1 General Description
All seating positions are provided with an emergency locki ng retractor lap-sash seatbelt assembly. The emergency
locking retractor mechanism locks the seatbel t webbing under one or more of the following conditi ons:
Angle of the retractor assembly (vehicle),
Acceleration or deceleration of the vehicle, and / or
Acceleration of the webbing.
Certain models have the option of height adjustable upper guide for the front seatbelts.
Both front seats also have a pyrotechn ic seatbelt pretensioner incorporated in the buckle assembly.
The conditions that determine the operation of seatbelt pretensioners an d inflatable restraints are difficult to quantify in
terms of speed or angles of impact. There are many other f actors involved, such as size of the object, the object’s ability
(or inability) to absorb some or all of the impact force, the speed at which the other object may have been travelling, etc.
Ultimately it is the impact force, or crash pulse, that is detected by the SDM or side-impact sensors which will trigger t he
pretensioners and inflatable restraints. Activation is n ot designed to occur in situations that would not provide a ny driver /
front passenger protection benefit.
It is normal in a low speed frontal or near frontal coll ision that none of the pretensioners or inflatable restraints will deploy,
as the crash pulse has not been great enough. In this situation the seatbelts should provide ade quate protection if worn
correctly.
In other situations, only the pretensioners may deploy as the crash pulse has been greater than the programmed
threshold to deploy the pretensioners, but not great enough to deploy the inflatable restraints which would deploy at a
higher programmed threshold.
Similarly, side-impact inflatabl e restraints will only deploy in situations where there is risk of serious injury to the
occupant, and only on the relevant sid e.
NOTE
A side-impact inflatable restraint will deploy
independently of the other inflatable restraints
and pretensioners.
The following table indicates the approximate tension / inflation times for the seatbelt pretensioners and inflatable
restraints:
Device Tension / Inflation Time
Pretensioner 5 ms
Steering Wheel and Instrument Panel Inflata ble R estraints 30 ms
Side-impact Inflatable Restraints 20 ms
Regular maintenance of the OPS is not required. Ho wever, if at any time the airbag warning indicator (located on th e
instrument cluster):
illuminates while driving, or
does not illuminate when the vehicle is started, or
remains illuminated after 5 seconds from when the ignition is turned on,
there is a system fault, and this must be rectified as soon as possible, refer to 2 Diagnostics.
The diagnostic scan tool Tech 2 is programmed to assist with electrical diagnosis and problem solving. Tech 2 connects
to the SDM serial data communication using t he Serial Data Link Connector (DLC) located below the steering column.
For additional information on DLC location and system diagnosis, refer to 2 Diagnostics. For more specific and
comprehensive information regarding Tech 2, refer to Section 0C Tech 2.
Occupant Protection System Page 12M–14
Page 12M–14
Accessory type or after-market bull bars or
such devices not approved may adversely
affect the vehicle's desired threshold
characteristics for restraint device
deployment.
Accessory type or after-market type dash
panel carpet covers or the like must not be
installed, as they will greatly inhibit the
performance of the inflatable restraint
assembly and front passenger's safety in
the event of an inflatable restraint
deployment.
Fitting of accessories such as drink
holders, cassette racks, add itional mirrors,
etc. are not permitted in the immediate
deployment area of the front instrument
panel inflatable restraints. These items
may be dislodged and propelled towards
the vehicle's occupants when the
inflatable restraint assembly is deployed.
Only approved accessor y and after-market
seat covers may be fitted to a vehicle w ith
side-impact inflatable restraints. Seat
covers that are not approved could greatly
inhibit the performance of the side-impact
inflatable restraint and occupant safety in
the event of side-impact in flatable restrai nt
deployment.
Front Seatbelt Pretensioners
The front seatbelt pretensione r assemblies deploy in two stages to protect the driver or front seat passe nger during
certain collisions, refer to Figure 12M – 3.
1 Before Deployment:
The pretensioner is in a state of readiness unless the SDM detects a fault, in which case the pretensioner
may not operate, and the airbag warning indicator on the instrument cluster will illuminate.
2 Fully Deployed:
The front seat belt pretensioner is fully retracted and the SDM records the data related to the prevaili ng
conditions and operation.
Figure 12M – 3
Occupant Protection System Page 12M–15
Page 12M–15
Steering Wheel Inflatable Restraint
The steering wheel inflatable restraint assembly deploys to protect the driver during certain collisions, refer to
Figure 12M – 4.
1 Before Deployment:
The steering wheel inflatable restraint is in a state of readin ess unl ess the SDM detects a fault, in which case
the steering wheel inflatable restraint may not operate, a nd the airbag warning indicator on the instrument
cluster will illuminate.
2 Fully Deployed:
The steering wheel inflatable restraint assembly is inflated and the SDM records the data related to the
prevailing conditions and operation.
3 During Restraint:
The force of the collision causes the he ad and upper torso of the driver to move for ward into the infl ated
restraint assembly. Gas is vented from the thorax or chest region of the bag to the head region, red ucing the
chest loads and providing support for the head and neck.
4 End of Collision:
The steering wheel inflatable restraint assembly deflates fully.
Figure 12M – 4
Occupant Protection System Page 12M–16
Page 12M–16
Instrument Panel Inflatable Restraint
The instrument panel inflatable restraint assembly deploys to protect the front passenger during certain collisions, refer to
Figure 12M – 5.
1 Before Deployment:
The instrument panel inflatable restraint is in a state of readiness unless the SDM detects a fault, in which
case the instrument panel inflatable restraint may not operate, and the airbag warning indicator on the
instrument cluster will illuminate.
2 Fully Deployed:
The instrument panel inflatable restraint assembly is inflated and the SDM records the data related to the
prevailing conditions and operation.
3 During Restraint:
The force of the collision causes the he ad and upper torso of the passenger to move forward into the inflated
restraint assembly. Gas is vented from the thorax or chest region of the bag to the head region, red ucing the
chest loads and providing support for the head and neck.
4 End of Collision:
The instrument panel inflatabl e rest raint assembly deflates fully.

Side-Impact Inflatable Restraints
The side-impact inflatable res t raint assembly deploys to protect the driver or passenger during certain collisions, refer to
Figure 12M – 6.
1 Before Deployment:
The side-impact inflatable res t raint is in a state of readiness unless the SDM detects a fault, in which case the
side-impact inflatable restraint may not operate, and the airbag warning indicator on the instrument cluster will
illuminate.
2 Fully Deployed:
The side-impact inflatable res t raint assembly is inflated and the SDM records the data related to the
prevailing conditions and operation.
3 During Restraint:
The force of the collision causes the he ad and upper torso of the driver or passenger to move sideways into
the inflated restraint assembly. Gas is vented from the thorax or chest region of the bag to the head region,
reducing the chest loads and providing support for the head and neck.
4 End of Collision:
The side-impact inflatable res t raint assembly deflates fully.

1.2 Components
Sensing and Diagnostic Module (SDM)
The Sensing and Diagnostic Module (SDM) (1) is a
centralised, self contained collision sensing and triggering
system that, with exception of the two side-impact sensors
for detecting lateral acceleration for the side-impact
inflatable restraint where fitted, requires no additional
external sensing inp uts.
The SDM is mounted under the floor conso le assembly and
consists of an electronic acceleration sensor system,
electronic control system, and ener gy storage devices. It's
electronics are capable of self diagnostics, fault memory
and collision event recording.
The primary function of the SDM is to sense collisi on events
and discriminate between those requiring and those not
requiring deployment of the pretension er and/or inflatable
restraint assemblies. Figure 12M – 7
In the case of a deployment event, the function of the SDM is to initiate the pretensioners, or the pretensioners and
inflatable restraint assemblies, in a timely manner in order to protect the vehicle occupants.
The SDM has the ability to command some aspects of the restraint devices indepe ndently of each other:
Deployment of the front seatbelt pretensione rs only, or
Front seatbelt pretensioners and inflatable restraint assemblies, or
Side-impact inflatable restraint assemblies.
The SDM also performs continual tests on the pretens ioner and inflatable restraint electrical circuits.
NOTE
The SDM is designed for a one-time deployment
use only and must be replaced after a
deployment. If deployment occurs and the SDM
is not replaced, the airbag warning indicator in
the instrument cluster will be continually
illuminated.
Integrated into the SDM are two piezoelect ric sensors (accelerometers) that constantly monitor the acceleratio n data of
the vehicle. Microprocessors wit hin th e SDM run the outputs from the accelerometers through a complex mathematical
algorithm. The respective outputs are compared to a set of stored values in the processor memory. If the processed
values exceed their set of stored values, the SDM provides an AC output signal to ignite the pyrotechnic gas generators
of the relevant OPS components.
The SDM electronic diagnostic function performs the following:
Continuously monitors the el ectrical circuits of the restraint devices.
Controls the airbag warning i ndicator in the instrument cluster to alert the driver of a detected system fault.
Provides a power reserve, in the form of a capac itor, to operate the restraint devices in case the vehicle s ystem
power is lost during a collision.
During deployment the SDM records and stores the foll owing OPS and collision event informatio n:
Diagnostic Trouble Codes (DTCs) for detected faults.
Airbag warning indicator operation data.
Pretensioner and inflatable restraint deployment event data.
Occupant Protection System Page 12M–19
Page 12M–19
The SDM communicates diag nostic information through the Serial Data Li nk Connector (DLC) for the follo wing purposes:
System checks at the vehicle assembly plant.
Service diagnosis (using Tech 2).
Transmitting of collision event recording data for post collision analysis.
Additionally, in the event of restraint device deployment, the SDM will send serial data using the auxiliary serial data bus
(circuit 774) to advise various vehicle systems to take appropriate shutdown action.
The Powertrain Control Module (PCM) or Engine Contro l Module (ECM) monitors this serial data and p erforms a vehicle
shutdown once the appropriate data is identified and the vehicle speed is zero for more than 10 seconds.
The Body Control Module (BCM) also monitors this serial data and performs the following actions once the appropriate
data is identified and the vehic le speed is zero for more than 10 seconds:
1 Turns the interior compartment lamp on continuously.
2 Unlocks all doors.
NOTE
This is only effective for the ignition cycle in which
the deployment(s) occurred. Providing the
vehicle's electrical system is functional, cycling
the ignition will restore normal function.
There are three different, non-interchangeable SDM configurations. These can be identified by the last digit of the part
number:
3 3 loop system for pretensioners and steering wheel inflatable restraint only.
4 4 loop system for pretensioners, steering wheel inflatable restraint, and instrument panel inflatable restraint.
6 6 loop system for pretensioners, steering wheel inflatable restraint, instrument panel inflatable restraint, and side-
impact inflatable restraints.
NOTE
Always refer to the latest MY 2005 VZ spare
parts information for the latest part numbers
when ordering OPS components.
Figure 12M – 8 illustrates the SDM connector pins without side-impact inflatable restraints (A) and the SDM conn ector
pins with side-impact inflatable restraints (B).
Figure 12M – 8
Occupant Protection System Page 12M–20
Page 12M–20
Side-impact Sensor Assembly
The inflatable restraint side-impact sensor assembly (1),
also known as a peripheral acceleration sensor, is a sensing
component mounted on a bracket (2) attached to the centre
pillar (3) on each side of the vehicle.
The side-impact sensor is able to detect lateral acceleration,
recognise a collision, and s en d a sign al to the SDM that a
side-impact inflatable restraint deployment situation exists.
The SDM will then determine wheth er or not to deploy the
relevant side-impact inflatabl e restraint assembly.
Side-impact sensors are only fitted to vehicles with side-
impact inflatable restraints.
NOTE
Due to the critical nature of the torque
specification of the two nuts (4) attaching the
side-impact sensor to the mounting bracket, the
side-impact sensor is serviced with the mounting
bracket as an assembly only.
If there is a need to remove the side-impact sensor from the
vehicle, it must be removed as an assembly with the
mounting bracket attached.
Figure 12M – 9
NOTE
A side-impact sensor is designed for a one-
time deployment use only. If a side-impact
inflatable restraint deploys, the side-impact
sensor and mounting bracket assembly on the
same side as the deployed inflatable restraint
must be replaced.
Figure 12M – 9 shows the RHS side-impact
sensor and the wiring harness facing the rear
of the vehicle. The side-impact sensors are
uni-directional. The LHS side-impact sensor
has the wiring harness facing the front of the
vehicle.
Occupant Protection System Page 12M–21
Page 12M–21
Seatbelt Pretensioners
Each front seatbelt is equipped with a pyrotechnic seatbelt pretensioner. The purpose of the pretensioner is to remove all
webbing slack from the seatbelt before the occupa nt has moved forward as the result of a frontal collision.
Refer to Figure 12M – 10 for the following.
The pretensioner has an igniter and gas generator (4) contained within a cylinder. Inside the cylinder is the retractor
cable piston (5) connected to both ends of the buckl e retractor cable (3). The cable passes through the retractor cable
interlocking cam (2) and then forms a loop internally in the seatbelt buckle assembly (1).
NOTE
The seatbelt buckle switch (7), is only fitted to
driver side seat pretensioner assembli es.

B Seatbelt and Pretensioner Assembly Fully Deployed
When an ignition signal from the SDM is sen t to the igniter, the gas generator is activated driving the retractor cable
piston down the cylinder. This action pulls the cable through the retractor cable interlocking cam and pulls the buckle
towards the seat, taking up the slack in the seatbelt. The retractor cable along with the piston is prevented from moving
back up the cylinder by the retractor cable interlocking cam. Once a load ha s been applied in the opposite direction of
deployment, the clamping action of the interlocking cam directly on the cable prevents further moveme nt.
Occupant Protection System Page 12M–22
Page 12M–22
Clock Spring Coil Assembly
The clock spring coil assembly consists of the following
parts:
A rotating inner hub (1) which eng ages with the rear of
the steering wheel.
A wiring harness connector (2) which is incorporated
within the clock spring coil out er housing.
A wiring harness (3) that connects to the steering
wheel inflatable restraint assembly (3A) and the
steering wheel horn bar and remote rad io co ntrols
(3B).
An internal ribbon wire assembly (not shown) that
provides an unbroken connection between the
connector (2) and harness (3) as the steering wheel is
rotated.
The coil assembly operates i n the following manner:
When the steering wheel is in the straight-ahead
position, the inner hub and outer housing are aligned
to provide approximatel y 2.5 turns of the steerin g
wheel in either direction.
Figure 12M – 11
When the steering wheel is turned i n a clockwise direction (right turn), the inner h ub winds the ribbon wire as it
rotates with the steering wheel.
When the steering wheel is turned i n an a nti-clockwise direction (left turn), the inner hub unwinds the ribbon wire as
it rotates with the steering wheel.
Steering Wheel Inflatable Restraint Assembly
The steering wheel inflatable restraint assembly contains four main components, refer to Figure 12M – 12.
The inflatable restraint assembly deploys through the steering wheel inflatable restraint trim cover.

Inflator Assembly
Referring to Figure 12M – 13, the inflator assembl y contains the following:
An Electro Explosive Device (EED) (1). The EED consists of an electrical heating element (called a squi b) and a
small amount of lead styphnate covered with a mixture of titanium hydride and potassium perch lorate.
An enhancer pack (2) with appro ximately 3 grams of barium potassium nitrate.
A carbon based non-toxic composite propellant (3).
A fine particle filter (4).
Nitrogen gas exhaust ports (5) for the inflatable restra int assembly cushion.
EED wiring connector pins (6).
Figure 12M – 13
During deployment, the inflatable restraint assembly operates in the foll owing sequence:
1 The EED receives electric current from the SDM and begins a chemical reaction by igniting the lead st yphnate and
the mixture of titanium hydride and potassium perchlorate.
2 The reaction of the lead styphnate, titanium hydride and potassium perchlorate ignites the barium potassium nitrate
in the enhancer pack.
3 The enhancer pack chem ical reaction causes the carbon based non-toxic composite propellant to rapidly produce
nitrogen gas that expels through the outlets.
4 The nitrogen gas fills the inflatable restraint assembly cushion, which separates the steering wheel trim cover and
inflates.
5 As the inflatable restraint assembly cushion expands, some of the nitrogen begins to exit into the passenger
compartment through vent holes of a calibrated size at the base of the cushion. This permits the gas to escape,
enhancing the cushioning effect, and provides deflation of the cushion.
After deployment, the surface of the cushion may contain a powdery residue. This powder consists primarily of
cornstarch (used to lubricate the cushi on) and by-products of the chemical reaction, such as carbon mo noxide (CO),
nitrogen (N), carbon dioxide (CO2), water (H2O), with trace amounts of oxides of nitrogen (NOΧ) and ammonia (NH 3). As
a precaution, gloves and safety glasses are recommended when handling a deployed inflatable restraint assembly to
prevent any possible irritation of the skin or eyes.

Instrument Panel Inflatable Restraint Assembly
Components of the instrument panel
inflatable restraint assembly are not
repairable. Under no circumstances are the
components of the instrument panel inflatable
restraint assembly to be disassembled. The
inflatable restraint assembly contains a
pyrotechnic gas generator and the inflatable
restraint assembly cushion fold is critical to
inflatable restraint assemb ly performance an d
front passenger's safety.
The instrument panel inflatable restraint assembly contains five main components, refer to Figure 12M – 14.
The inflatable restraint assembly deploys through the instrument pan el inflatable restraint openin g trim cover. The
opening trim cover is a PVC and foam laminate over a n in jection moulded plastic insert, with a sheetmetal hinge heat
staked to the rear surface. This assembly is then attached to the instrument pane l pad assembly with four screws.

Referring to Figure 12M – 15, the inflator assembl y contains the following:
EED wiring connector pins (1).
An Electro Explosive Device (EED) (2). The EED consists of an electrical heating element (called a squi b) and a
small amount of lead styphnate covered with a mixture of titanium hydride and potassium perch lorate.
Exhaust ports (3).
Diffuser (4), which is a hollow circular mesh that reduces the turbulence of the gas exiting through the exhaust
ports.
Burst Disc (5).
Actuator piston, striking primers and enha ncer pack (6)

Radial holes (8), which allow the gases to flow throughout the assem bly.
Argon gas (9).
Occupant Protection System Page 12M–25
Page 12M–25
Figure 12M – 15
During deployment, the inflatable restraint assembly operates in the foll owing sequence:
1 The EED receives electric current from the SDM and detonates the charge, firing the squib through the burst disc.
2 Once the burst disc is ruptured, argon gas begins to flow through the radial holes and the diffuser into the cushion.
The force produced by the gas and the rapidly inflating cushion separates the protective cover, and then forces the
hinged instrument panel i nflatable restraint opening trim cover open to fully deploy the inflatable restraint assembly
cushion.
3 In the same instance, the squib impacts with the actuator piston, detonating the striking primers and ign iting the
hybrid propellent.
4 Heat and nitrogen are genera ted by the chemical reaction of the hybrid propellent. The argon is heated and
expands which, with the nitrogen produced by the propellent, further inflates the cushion.
Internal tethering controls the fill and placement of the inflatable restraint assembly cushion to maximise the benefits to
the front passenger.
The windshield is used to support and position the inflatable restraint assembly cushion. In some deplo yment cond itio ns,
the windshield may be broken by the opening of the instrument panel inflatable restraint open ing trim cover when the
inflatable restraint assembly cushion deploys.
After deployment, the surface of the cushion may contain a powdery residue. This powder consists primarily of
cornstarch (used to lubricate the cushi on) and by-products of the chemical reaction such as carbon monoxide (CO),
nitrogen (N), carbon dioxide (CO2), water (H2O), with trace amounts of oxides of nitrogen (NOΧ) and ammonia (NH 3). As
a precaution, gloves and safety glasses are recommended when handling a deployed inflatable restraint assembly to
prevent any possible irritation of the skin or eyes.

Side-impact Inflatable Restraint Assembly
Components of the side-impact inflatable

assembly contains compressed gas and a
small pyrotechnic charge. Additionally, the
inflatable restraint cushion fold is critical to
inflatable restraint performance and front
occupant safety.
The side-impact inflatable res t raint assembly contains five main components, refer to Figure 12M – 16.
The inflatable restraint assembly deploys through the seat back foam an d seat back fabric at the forward side seam,
providing a protective barrier between the occupant and the vehicle door.

Referring to Figure 12M – 17, the inflator assembl y contains the following:
A small amount of oxidiser (1).
A small amount of fuel (ethanol) (2).
Compressed inert gas (t ypically Argon) in a sealed chamber (3).
An initiator (4), which consists of an electrical heati ng element (called a squib), covered with a mixture of sensitive

Exhaust ports (8).
Occupant Protection System Page 12M–27
Page 12M–27
Figure 12M – 17
During deployment, the side- impact airbag inflator operates in three stages:
1 The initiator receives electric current from the SDM, heating the sensitive pyrotechnic charge, which ignites the fuel.
2 The combustion of the fuel and oxidiser creates enough pressure to burst the disks, heating the compressed gas
and allowing it to escape into the cushion.
3 The heated expanding gas starts to unfold the inflatable restraint cushion, which separates the protective cover, the
seatback foam and the seatback fabric, and inflates.
As the cushion inflates, some of the gas begins to exit into the passenger’s compartment through vent holes or through
the pores of the cushion fabric. Internal tethering controls the fill and placement of the airbag to maximise the benefits to
the front occupant.

indicate the system start-up sequence. During this period the SDM performs a system wiring and self check. If no
system faults are detected, the airbag warning indicator will be switched off.
If communication is lost between the SDM and the instrument cluster (for example SDM wiring harness
disconnected or no BCM pol l) the airbag warning indicator will be illuminated when the ignition is first switched on
and then commanded on constantly until the fault is remedied (communication resumed) (No DTC will set).
If an inflatable restraint assembly and/or pretensioner is deployed, the airbag warning indicator will be illuminate d
until the problem is resolved (No DTC will set).
If one or more current or history Diagnostic Trouble Codes (DTCs) are detected when the ignition is s witched on,
the airbag warning indicator will illuminate a nd remain illuminated until the DT C is cleared. Additionally, 3 seconds
after the ignition is switched on, an audible warning chime will sound.
During an ignition cycle, if the SDM detects a current DTC, the airbag warning indicator will be illuminated. If during
this cycle, the current DTC fault condition clears, a history DTC will be logged i n the SDM and the airbag warning
indicator will still remain illuminated.
When Tech 2 is communicating with the SDM, the airbag warning indicator will be illuminated and the inflatable
restraint assemblies and pret ensioners will be disabled.
For details on all DTCs, refer to 2 Diagnostics in this Section.
Multi-function Display
In addition to the airbag warning indicator, the instrument cluster has a Multi-function Display (MFD), which displays a
warning message Airbag Fault (2) to alert the driver of a possible fault with the system, refer to Figure 12M – 18.
The MFD warning message is controlled by the BCM. The MFD warning message is activated by the BCM when the
SDM sets a poll response message, using the serial data circ uit.
For more information, refer to Section 12C Instruments.
Chime Alert
The airbag warning indicator and MFD are complemented by a warning chi m e to alert the driver audibly of a possible
fault with the system.
The warning chime alert is controlled by the BCM. The warning chime alert is activated by the BCM when the SDM sets
a poll response message usin g the serial data circuit.
For more information, refer to Section 12C Instruments.
Seatbelt Warning Indicator
The seatbelt warning indicato r (3), refer to Figure 12M – 18, uses a ground circuit provided by the driver’s seatbelt b uckle
switch to turn off the indicator. Whenever the ignition is turned on, the seatbelt warning ind icator LED illuminates
continuously for 60 seconds. If the seatbelt has not been fastened during this period, the indicator will flash for a further
90 seconds at which point it will extinguish, e ven if the seatb elt is not fasten ed.
When illuminated, the indicator will extinguish as soon as the driver’s seat belt is fastened.
If the seat belt is removed after having been fastened, the indicator illuminates continuously again, and the cycle repeats.
For information on the seatbelt buckle switch, refer to Seatbelt Buckle Switch in this Section.
Seatbelt Buckle Switch
The seatbelt buckle switch is a microswitch located in the buckle part of the pretensioner assembly. It is only fitted to the
driver’s pretensioner assembl y. The switch is not connected to the SDM.
The switch provides a ground circuit for the seatbelt warning indicator on the instrument cluster, when the seatbelt is not
inserted into the buckle. When the seatbelt is inserted into the buckle, the contact on the microswitch is broken and the
path to ground is open-circuit, refer to 2.15 Seatbelt Buckle Switch in this Section.
For further information on the seatbelt warning indicator, refer to Seatbelt Warning Indicator in this Section.

Wiring Harness
Due to the sensitive nature of the circuitry for
restraint devices, special wiring repair
procedures have been developed, refer to
Section 12P Wiring Diagrams. These are the
only recommended and approved wiring
repair methods for restraint devices.
The wiring harness for restraint devices can be identified by the yellow PVC tubing or yellow tape covering the harness
wiring. Specific wiring harness connectors for restraint devices are either coloured yellow, mustard or orange, or have a
yellow retaining clip or slide to identify them.
The connectors on the wiring harness for restraint devices, which interface with the igniters, have an in-built capacitor,
which is connected in series with the trigger circuit. The purpose of the capacitor is to prevent unintentional triggering of
the restraint devices by blocking an y Direct Current (DC) in the circuit.
Figure 12M – 20 illustrates the wiring harness connector
with an in-built capacitor. The connector consists of:
Capacitor (1).
Service holes to aid in diagno s is of the system (2).
Connector Pins (3).
Figure 12M – 20
Occupant Protection System Page 12M–31
Page 12M–31
1.3 System Operation – Inflatable Restraint
and Pretensioner Assemblies
Each of the inflatable restraint assemblies and pretensioners has a built in capacitor as part of the circuit.
This capacitor acts as a safety function within the circuit so that if either of the two wires that form the harness are
shorted to ground or battery, there will be no current flow and therefore the inflatable restraint assembly will not deploy.
A capacitor will only allow current flow with an alternating current (AC) supply. As the battery is direct current (DC) the
capacitor will not allow current flo w if it is shorted to a DC suppl y.
Within the SDM, a ‘H’ bridge circuit is used to supply the inflatable restraint assembly with an AC supply when the SDM
senses an impact that requires deployment of the restraint assembly. The 'H' bridge circuit is used to allow readiness in
the case of single wiring harness faults. The bridge structur e allows several firing paths so the restraint assembly can be
deployed even if one of the four power transistors is faulty.
NOTE
S1, S2, S3, and S4 denote the four transistors
that form the ‘H’ bridge circuit, refer to
Figure 12M – 21, which sho ws the steeri ng wheel
inflatable restraint assembly wiring diagram. All
firing loops function in the same manner.
The ‘H’ bridge has two sources of supply; the internal capacitor (ER) of the SDM, which is the energy reserve sup pl y,
and battery positive. The function of the energy reserve, which stores 45 V, is to provide power for restraint assembly
deployment in the situation where battery positive is not available to the SDM (if the battery positive supply is interrupted
during an impact).
The following firing modes are a breakdown of the SDM converting DC into AC and the supply of that AC to the inflatable
restraint assembly to cause a deployme nt.
Firing Modes 1 and 2 are activated alternately for several cycles respectively. If the voltage at the po wer stages has
dropped to below 25 V, Mode 3 is started. If the energy res erve is not avai lable for any reason when firing is required,
only battery voltage at the power stage is present, and firing occurs immediately with Firing Mode 3.
Occupant Protection System Page 12M–32
Page 12M–32
Firing Mode 1
Firing Mode 1 is designed to activate the initiator (1) in the event the negative side of the firing loop (circuit 3020) is
shorted to ground or battery, refer to Figure 12M – 21. Throughout Firing Mode 1, S3 grounds this side of the circuit.
When the circuit is charging (A), the ER supplies power to the positive side of the firing loop (circuit 3021) through switch
S1.
When the circuit discharges (B), S1 opens and S2 closes providing a ground circuit for the positive side of the firing loop.
The charging and disc harging (the opening and closing of S1 and S2) is every 5 µs. The AC created by the alternating
switching of the ‘H’ bridge will cause current flow through the capacitor (2) and the initiator to activate.
Figure 12M – 21
Occupant Protection System Page 12M–33
Page 12M–33
Firing Mode 2
Firing Mode 2 is designed to activate the initiator (1) in the event the positive side of the firing loop (circu it 3021) is
shorted to ground or battery, refer to Figure 12M – 22. Throughout Firing Mode 2, S2 grounds this side of the circuit.
When the circuit is charging (A), the ER supplies power to the negative side of the firing loop (circuit 3020) through
switch S4.
When the circuit discharges (B), S3 opens and S4 closes providing a ground circuit for the negative side of the firing
loop. The charging and disch arging (the opening a closing of S3 and S4) is every 5 µs. The AC created by the alternating
switching of the ‘H’ bridge will cause current flow through the capacitor (2) and the initiator to activate.
Figure 12M – 22
Occupant Protection System Page 12M–34
Page 12M–34
Firing Mode 3
Firing Mode 3 is designed to charge and discharge both the positiv e and negative side of the firing loop when the Energy
Reserve (ER) falls below 25 V.
When charging (A), S1 is closed al lowing both battery and ER power through the positive side (circuit 3021), refer to
Figure 12M – 23. During this cycle, S3 is closed, provi ding a ground for circuit 3020. S2 and S4 are both open.
When discharging (B), S4 is closed allowing both battery and ER power through the negative side (circuit 3020). During
this cycle, S2 is closed, providing a ground for circuit 3021. S1 and S3 ar e both open
The charging and disc harging (the opening a closing of S1 a nd S3; S2 and S4) is every 5 µs. Due to this charging of the
capacitor (2) via the firing element from posi t ive voltage to negative voltage, the firing voltage of this mode can be
considered to be doubled to 2 x ER (Energ y Reserve Voltage) or 2 x VBAT (Battery Voltage). As a result, AC firing from
battery voltage is possible.
The AC created by the alternating switching of the ‘H’ bridge will cause current flo w through the capacitor and the initiator
(1) to activate.
Figure 12M – 23
Firing Loop Monitoring
The firing loop monitoring e nsures that failures in the firing leads and initiators that could affect triggering are identified.
The following errors in the firing loops or initia tors are detected:
Short circuit or leakage resistance to ground or battery voltage.
Short circuit or shunt circuit between firing leads of the firing loop.
Resistance of the initiator too high or too lo w.
Capacitance of the firing loop capacitor too high or too low.
When the SDM detects any of the above faults, it will produce a Diagnostic Trouble Code (DTC) and illuminate the airbag
warning indicator. For further details refer to 2 Diagnostics.

to diagnose wiring harness connectors.
Backprobe the connector to avoid terminal
damage.
When tests are required on connector
terminals, use the adapters in the
connector adapter kit KM–609 to prevent
damage to the terminals.
Unless the multimeter being used has an
auto-ranging function, ensure the correct
range is selected.
When backpro bing connectors, ensure the
test lamp ground lead is connected to an
appropriate ground point on the vehicle.
Ensure this ground point is not part of the
circuit being tested.
NOTE
When following the steps in the di agnostic tables,
perform them in the order cited. If the required
nominal value or result is not achi eved, rectif y t he
problem before proceeding.
Before attempting to diagnose the Occupant Protection System (OPS) the technicia n must have a good understanding of
electrical system basics and the use of circuit testing tools. Without this basic knowledge it will be difficult to use the
diagnostic procedur es detailed in this Section.
Some electrical basics, as well as basic troubleshooting procedures and hints of the use of circuit testing tools are
covered in Section 12P Wiring Diagrams.
The technician should understand the following:
The meaning of voltage (V), current (A), and resistance (),
basic theory of electricity, direct current (DC) theory, series and parallel circuits, and voltage drops acros s series
resistors,
alternating current (AC) theory including in ductance, capacitance and impedance,
what happens in a circuit with an open or shorted wire (shorted either to voltage or ground), and
be able to read and interpret a wiring diagram.
The tables in this Section are used by the technician in the aid of diagnosing faults in the OPS. To aid in the use of the
diagnostic tables refer to 2.2 Wiring Diagr am and 2.3 Connector Chart.

2.4 System Self Diagnosis
The Sensing and Diagnostic Module (SDM) has a self-diagnostic facility that can detect and isolate system problems or
failures. When a condition or failur e is detect ed, the SDM sets a fault code that represents that particular condition or
failure. Fault codes will cause the airbag warning indicator to be illuminated and an airbag fault message is displayed by
the Multi Function Display (MFD) located in the instrument cluster. Depending on the fault, the SDM ma y disable the
inflatable restraint and pretensioner assemblies.
If present, diagnosable system faults are detected by the SDM during an initial isation process when the ignition is first
turned on. Upon first detection of a system fault condition, the SDM records the failure and classes the failure as
intermittent. If the condition is maintained to meet the failure duration conditions for the indivi dual system fault
(approximately 3 to 5 seconds), the fault then becomes a current Diagnostic Trouble Code (DTC). If the fault duration
conditions are not met, the intermittent fault i s cleare d from the SDM.
Current DTCs are permanentl y stored in the SDM memory. When the fault conditions are no longer met, the DTC will
become a History DTC.
DTCs – Current
Current DTCs, when detected, are stored in the SDM memory during the current ignition cycle and then maintained in an
EEPROM.
Current DTCs are set or cleared based on conditions in the OPS during ignition on or continuous monitoring of the
current ignition cycle.
NOTE
A current DTC can be identified on Tech 2
display by the word Current between the DTC
number and the DTC description. The word
History between the DTC number and the DTC
description indicates the DTC displayed is a
history DTC.
Current DTCs will be reset to history DTCs upon the next diagnostic test sequence the fault conditions are not met.
Current DTCs can be cleared (changed to history DTC) by removing the fault conditio ns.
Tech 2 is unable to clear current DT Cs if the fault conditions still exist; Tech 2 will display Clear DTC Information
Failed.
DTCs stored in the SDM memory can only be displ ayed and / or cleared using Tech 2 diagnostic scan tool.
Tech 2 communicates with SDM serial data usin g the Seri al Data Link Connector (DLC), which is attached to the
instrument panel lower left-hand trim retainer, refer to Section 0C Tech 2.
DTCs – History
History DTCs are set upon the cleari ng of a current DTC fault condition. History DTCs are maintained b y the SDM over
multiple ignition cycles in the EEPROM. The SDM can only clear history DTCs from its EEPROM by a Clear DTCs serial
data message from Tech 2.
Erasing DTCs
Once any system fault has been rectified, using Tech 2 Clear DTCs selection will erase any fault codes stored in the
SDM memory, refer to Section 0C Tech 2.
NOTE
Once DTCs have been cleared, be sure to verify
proper system operation and absence of an y fault
codes when clearing procedure is completed. If
Tech 2 displays Clear DTC Information Failed
after attempting to clear DTCs, the fault condition
still exists.

2.5 Preliminary System Diagnosis
Prior to starting any diagnosis, the technician should be familiar with the OPS components and operation. For a
description of the components and the system operation, refer to 1 General Information.
When investigating any complaint of a pro blem or malfunction, always begin diagnosis with a circuit check, refer to
System Diagnostic Check.
The diagnostic circuit check ensures the SDM is communicating on the serial data line, assists identification of the
problem, and helps ascertain the appropriate diagnostic table.
Occupant Protection System Page 12M–45
Page 12M–45
2.6 Electrical Diagnosis
Introduction
The following diagnostic table s are designed to aid fast and efficient fault location and remedy. The dia gnostic tables
include a table, pertinent information, and where necessary, the steps are explained by the corresponding numbered
paragraphs.
To aid in the use of the diagnostic tables, refer to 2.2 Wiring Diagram and 2.3 Connector Chart.
When performing wiring checks as directed to by the diagnostic tables, rat her than probe pins and connectors with
incorrect sized multimeter connectio ns, use the ad apters contained in connector test adaptor kit Tool No. KM-609 and
test lead set Tool No. KM609-20. This will prevent any possibility of spreading or damaging wiring harness pins which
may cause a system intermittent failure.
Figure 12M – 26 illustrates the correct use and instal lation of the various diagnostic tools (Tool No. SD28280B, Tool No.
AU485, Tool No. EL47787 and test lead set Tool No. KM609-20).
Under no circumstances is 12 V to be applied
to the dummy load, Tool No. SD28280B, Tool
No. EL47787, or Tool No. AU485, as this will
damage the internal resistor in the load,
rendering the dummy load useless for any
further diagnostic work.
Ensure at the completion of any diagnostic proced ure, all di agnostic tools are removed and all OPS compon ents are
correctly reconnected.

System Diagnostic Check
Introduction
When investigating any concern with the OPS, always begin diagnosis with the following diagnostic circuit check. This
checks for a fault with the airbag warning indicator, regardless of whether the OPS is serviceable or not.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2-3 Checks if the airbag warning indicator illuminates when the ignition is turned on. The SDM performs a self-check of
the OPS when the ignition is turned on. During this check, the SDM through the serial dat a bus, instructs the
instrument cluster to illuminate the airba g warning indicator for 5 seconds. If there is a fault in the OPS, the SDM
will instruct the airbag warning indicator to stay on. Isolates whether there is a problem with the airbag warning
indicator or if the fault is in the OPS.
4 Checks if any DTCs have been set. Isolates if a DT C has been set causing the airbag warning indicator to remain
illuminated.
Diagnostic Table Notes
1 For all wiring harness fault diagnoses, refer to Section 12P Wiring Diagrams.

Introduction
This test is used by the technician to aid in diagnosis when the air bag warning indicator is inoperativ e.
Circuit Description
Battery voltage is supplied to the airbag warning indicator through fuse F 13 (located on the passenger compartment fuse
and relay panel assembly) when the ignition switch is in the IGN or ST ART positions. The airbag indicator in the
instrument cluster is illuminated and extinguished by serial data from the SDM.
The airbag warning ind icator will illuminate:
When the ignition is turned to the ON position (system wiring and self-check). The airbag warning indicator will be
turned off after this self-check if no current or history Diagnostic Tr ouble Codes (DTCs) are detected.
If communication is lost between the SDM and the instrum ent cluster.
If the instrument cluster has not been programmed for the vehicle configuration.
If the SDM detects a current DTC during an ignition cycle.
When the battery voltage is belo w 8 V or above 21.2 V.
If the pretensioners or inflatable restraint assemblies have deployed.
If the energy reserve in the SDM is activated (battery voltage is less than 7.5 V).
If the SDM does not receive a poll from the BCM.

Airbag Warning Indicator Illuminated (No DTC Stored)
Introduction
This test ensures the SDM is communicating on the serial data line, to identify a failure or malfunction an d to provid e a
reference to the appropriate diag nostic table in this Section.
Circuit Description
With Tech 2 connected to the DLC and the ignition on, Tech 2 should display serial data communication, refer to
Section 0C Tech 2. If Tech 2 does not display serial data, the serial data circuit maybe open-circuite d or short-circuited.
There are several other control modules that are connected to the serial data line (PCM, BCM, ABS/ETC, instrument
cluster and the SDM). Any one of these control modules could cause a fault on the serial data line. This fault cou ld result
in Tech 2 not being able to displa y serial data.
Battery voltage is supplied to the airbag warning indicator through fuse F 13 (located in the passenger compartment fuse
and relay panel assembly) with the ignition switch in the IGN or START positions. To illuminate the indicator, the SDM
sends a serial data message to the BCM via circuit 774 and the BCM sends a serial data message to the instrument
cluster via circuit 1061, requesting the airbag indicator to illuminate.
When the ignition is switched on, the airbag warning indicator should illuminate for approximately 5 seconds to indicate
the system start up sequence / system wiring and self check. If no system faults are detected, the airbag warning
indicator will then be switched off.
If a fault is detected (either during this system check or during the ignition cycle), the airbag warning indic ator will either
remain on until the fault is remedied or, if a DTC has been set, until the DTC is cleared. If a fault is remedied during an
ignition cycle, unless the fault caused a DTC to set, the airbag warning indicator will turn off immediately.
The airbag warning ind icator will illuminate:
When the ignition is turned to the ON position (system wiring and self-check). The airbag warning indicator will be
turned off after this self-check if no current or history Diagnostic Tr ouble Codes (DTCs) are detected.
If communication is lost between the SDM and the instrum ent cluster.
If the instrument cluster has not been programmed for the vehicle configuration.
If the SDM detects a current DTC during an ignition cycle.
When the battery voltage is belo w 8 V or above 21.2 V.
If the pretensioners or inflatable restraint assemblies have deployed.
If the energy reserve in the SDM is activated (battery voltage is less than 7.5 V).
If the SDM does not receive a poll from the BCM.
The airbag warning indicator will a lso be illuminated if communication is lost (no serial data) between the SDM and
the instrument cluster.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the cause of the airbag warning indicator
being illuminated.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 The SDM performs a self-check of the OPS when the ignition is turned on. During this check, the SDM through the
serial data bus, instructs the instrument cluster to illuminate the air bag warning indicator for 5 seconds. If there is a
fault in the OPS, the SDM will instruct the airbag warning indicator to stay on. Isolates whether the fault is in the
OPS or there is an intermittent fault (this check has already been performed in S ystem Diagnostic Check).
3 Checks if there is serial data communication between the SDM and Tech 2. This also verifies if the SDM has power
and a ground circuit.
4 Checks if any DTCs have been set. Isolates if a DT C has been set causing the airbag warning indicator to remain
illuminated.
5 Checks if the BCM has polled the SDM.
6 Checks if the instrument cluster is configured for the OPS.
8 Checks if the energy reserve has been activated. If the voltage supply to the SDM falls below 7.5 V, the energy
reserve in the SDM is switched on.
9 Checks the voltage supply to the SDM. If the battery voltage to the SDM falls below 8 V or rises above 21.2 V for
more than 3 seconds, the airbag warning indicator will illumi nate.

2.7 Steering Wheel Inflatable Restraint
Assembly DTCs
DTC 17 – Driver Airbag Circuit Short to Battery
Introduction
This test is used by the technician to aid in diagnosis when DT C 17 has been logged.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 17 will set and the airbag warning indicator will illuminate when the SDM detects the resistance to
battery positive is less than 5 k in eith er the positive and/or the negative circuit for more than 3 – 5 seco nds.
A current DTC 17 will set and the airbag warning indicator will illuminat e whe n circuit 3021 and/or circuit 3020 are
shorted to battery positive.
When DTC 17 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 17. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 17. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 17 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 17 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 17 is set, the steering wheel inflatable restraint assembly will still be operational due to the reserve energy supply
stored in the SDM.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the steering wheel inflatable restraint
assembly and associated components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Checks whether DTC 17 is current or history.
3 Checks for a short-circuit to battery positive in circuit 3021.
4 Checks for a short-circuit to battery positive in circuit 3020. Isolates whether circuit 3020 or the SDM is at fault.

DTC 18 – Driver Airbag Circuit Short to Ground
Introduction
This test is used by the technician to aid in the diagnosis of the steering wheel inflatable restraint assembly positive and
negative power supply circ uits.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 18 will set and the airbag warning indicator will illuminate when the SDM detects the resistance to ground
is less than 3 k in either the positive or negative inflator circuit for more than 3 – 5 sec onds, refer to
2.4 System Self Diagnosis for more details.
A current DTC 18 will set and the airbag warning indicator will illuminat e whe n circuit 3021 and/or circuit 3020 are

DTC 19 – Driver Airbag Circuit Capacitance Too High
Introduction
This test is used by the technician to aid in the diagnosis of the clock spring coil assem bly.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 19 will set and the airbag warning indicator will illuminate when the SDM detects the capacitance in the
steering wheel inflatable restraint assem bl y circuit is too high (greater than 550 nF) for longer than 3 – 5 seconds, refer to
2.4 System Self Diagnosis for more details.
A current DTC 19 will set if the in-built capacitor in connecto r A106 – X1 is faulty.
When DTC 19 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 19. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 19. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 19 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 19 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
Action Required
If DTC 19 is set, the steering wheel inflatable restraint assembly may not operate. The clock spring coil assembly must
be replaced as connector A106 – X1, with the in-built capacitor, is part of the clock spring coil assembly.
Refer to 3.7 Clock Spring Coil Assembly for the correct procedure on replacing the cl ock spring coil assembly.
After the clock spring coil assembly has been replaced, ensure all OPS components are reconnected, and the SDM is
enabled. Clear any DTCs, then verify the correct operation of the system (i.e. airbag warning indicator not illuminated
after 5 seconds of ignition being turne d on).
DTC 20 – Driver Airbag Circuit Capacitance Too Low
Introduction
This test is used by the technician to aid in the diagnosis of the clock spring coil assem bly.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 20 will set and the airbag warning indicator will illuminate when the SDM detects the capacitance in the
steering wheel inflatable restraint assem bl y circuit is too low (less than 390 nF) for longer than 3 – 5 seconds, refer to
2.4 System Self Diagnosis for more details.
A current DTC 20 will set if the in-built capacitor in connecto r A106 – X1 is faulty.
When DTC 20 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 20. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 20. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 20 is set, the airbag warning indicator will illuminate on each ignition cycle, even if the DTC is set as a history
DTC, until the fault conditions for setting DTC 20 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.

DTC 21 – Driver Airbag Circuit Resistance Too High
Introduction
This test is used by the technician to aid in the diagnosis of the steering wheel inflatable restraint assembly.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 21 will set and the airbag warning indicator will illuminate when the SDM detects the resistance in the
steering wheel inflatable restraint assem bl y circuit is too high (greater than 8.4 ) for longer than 3 – 5 seconds.
A current DTC 21 will set and the airbag warning indicator will illuminat e whe n circuit 3021 or circuit 3020 (including the
steering wheel inflatable restraint assem bl y and the clock spring coil) are open-circuit.
When DTC 21 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 21. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 21. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 21 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 21 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 21 is set, dependent on where the fault is, the steering wheel inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the steering wheel inflatable restraint
assembly and associated components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Checks whether DTC 21 is current or history.
3 Tool No. SD28280B is a dum my load taking the place of the steering wheel inflatable restraint assembly. If DTC 21
becomes a history DTC with the dummy load connected, the system fault is in the steering wheel inflat able restraint
assembly.
4 Checks if there is an open-circuit in the clock spring coil. If the clock spring coil is disconnected from the system,
and connector X116 – X1 pins 11 and 12 are bridged together, DTC 21 will become a history DTC if the clock
spring coil is faulty.
5 Checks for an open-circuit in circuit 3021.
6 Checks for an open-circuit in circuit 3020. Isolates whether circuit 3020 or the SDM is at fault.

DTC 22 – Driver Airbag Circuit Resistance Too Low
Introduction
This test is used by the technician to aid in the diagnosis of the steering wheel inflatable restraint assembly.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 22 will set and the airbag warning indicator will illuminate when the SDM detects the resistance in the
steering wheel inflatable restraint assem bl y circuit is too low (less than 1 ) for longer than 3 – 5 seconds.
A current DTC 22 will set and the airbag warning indicator will illuminat e whe n circuit 3021 or circuit 3020 (including the
steering wheel inflatable restraint assem bly and the clock spring coil) are shorted together.
When DTC 22 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 22. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 22. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 22 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 22 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 22 is set, dependent on where the fault is, the steering wheel inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the steering wheel inflatable restraint
assembly and associated components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Checks whether DTC 22 is current or history.
3 Tool No. SD28280B is a dum my load taking the place of the steering wheel inflatable restraint assembly. If DTC 22
becomes a history DTC with the dummy load connected, the system fault is in the steering wheel inflat able restraint
module.
4 Checks if there is a short-circuit in the clock spring coil. If the clock spring coil is disconnected from the system,
DTC 21 (open-circuit) will set and DTC 22 will become history. If DTC 21 sets and DTC 22 becomes history, the
clock spring coil is faulty.
5 Checks for a short-circuit between circuit 3021 and circuit 3020. Isolates whether there is a short-circuit between
circuit 3021 and 3020, or the SDM is at fault.

DTC 247 – Driver Airbag Circuit Power Stage Error
Introduction
This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self-test the SDM detects a fault with the steering wheel inflatable restraint assembly power stage, a current DTC 247
Driver Airbag Circuit Power Stage Error will set. On completion of the initial system self-test, the SDM then performs a
test of the steering wheel inflatable restraint assembly circuit. If the SDM detects a problem with this circuit, the
associated steering wheel inflatable restraint assembly circuit DTC will set and DTC 247 Driver Airbag Circuit Power
Stage Error will become a history DTC.
DTC 247 Driver Airbag Circuit Power Stage Error will set if a fault occurs in the steering wheel inflatable restraint
assembly circuit, clock spring coil assembly with the in-built capacitor connector A106 – X1, connector X116 – X1,
connector X303, the wiring harness, connector A65 – X1 or the SDM.
When a history DTC 247 Driver Airbag Circuit Power Stage Error sets, the SDM illuminates the airbag warning indicator.
Should the fault conditions det ected by the SDM clear during the same ignition cycle, the code will remain a history
DTC 247 Driver Airbag Circuit Power Stage Error for all ignition cycles until cleare d. The airbag warning indicator will
remain on for the remainder of the ignitio n cycle.
When DTC 247 Driver Airbag Circuit Power Stage Error sets, the SDM illuminates the airbag warning indicator for the
remainder of the ignition cycle. Should the fault conditions detected by the SDM clear during the same ignition cycle, the
code will remain a history DTC 247 Driver Airbag Circuit Power St age Error for all ignition cycles until cleared. T he airbag
warning indicator will also remain illuminated until the history DTC 247 Driver Airbag Circuit Power Stage Error is
cleared.
If DTC 247 Driver Airbag Circuit Power Stage Error is set, dependent on where the fault is , the steering wheel inflatable
restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the SDM and associated components.
Action Required
If DTC 247 Driver Airbag Circuit Power Stage Error and any other DTC are set then the diagnostics for the other DTC
should be carried out first. For example if DTC 247 Driver Airbag Circuit Power Stage Error and DTC 21 are set, the
diagnostics for DTC 21 should be carried out first.
If only DTC 247 Driver Airbag Circuit Po wer Stage Error is set then repl ace the SDM.
NOTE
An intermittent fault in the steering wheel
inflatable restraint assembly circuit may cause
DTC 247 Drivers Airbag Circuit Power Stage
Error to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. airbag warning indicator not illuminated after 5 seconds of ignition
being turned on).

DTC 247 – Passenger Airbag Circuit Power Stage Error
Introduction
This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self-test the SDM detects a fault with the instrument panel inflatable restraint assembly power stage, a current DTC 247
Instrument Panel Inflatable Restraint Assembly Circuit Power Stage Error will set. On completion of the initial system
self-test, the SDM then performs a test of the instrument panel inflatable restraint assembly circuit. If the SDM detects a
problem with this circuit, the associated instrument panel inflatabl e restraint assembly circuit DTC will set and DTC 247
Passenger Airbag Circuit Power Stage Error will become a history DTC.
DTC 247 Passenger Airbag Circuit Power Stage Error will set if a fault occurs in the instrument panel inflatable restraint
assembly circuit, connector A62 – X1 with the in-built capacitor, connector X205, connector X303, the wiring harness,
connector A65 – X1 or the SDM.
When a history DTC 247 Passenger Airbag Circuit Power Stage Error sets, the SDM illumi nates the airbag warning
indicator. Should the fault conditions detected b y the SDM clear during the same ignition cycle, the code will remain a
history DTC 247 Passenger Airbag C ircuit Po wer Stage Erro r for all ign ition cycles until cleared. The airbag warning
indicator will remain on for the remainder of the ignition cycle.
When DTC 247 Passenger Airbag Circuit Power Stage Error sets, the SDM illuminates the air bag warning indicator for
the remainder of the ignition cycle. Should th e fault conditions detected by the SDM clear during the same ignition c ycle,
the code will remain a history DT C 247 Passenger Airbag Circuit Power Stage Error for all ignition cycles until cleared.
The airbag warning indicator will also remain illumin ated until the history DTC 247 Passenger Airbag Circuit Power Stage
Error is cleared.
If DTC 247 Passenger Airbag Circuit Po wer Stage Error is set, dependent on where the fault is, the instrument panel
inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the SDM and associated components.
Action Required
If DTC 247 Passenger Airbag Circuit Po wer Stage Error and any other DTC are set then the diagnostics for the other
DTC should be carried out first. For example if DTC 247 Passenger Airbag Circuit Power Stage Error an d DTC 37 are
set, the diagnostics for DTC 37 should be carried out first.
If only DTC 247 Passenger Airbag Circuit Power Stage Erro r is set then the SDM should be replaced.
NOTE
An intermittent fault in the instrument panel
inflatable restraint assembly circuit may cause
DTC 247 Passenger Airbag Circuit Power Stage
Error to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. airbag warning indicator not illuminated after 5 seconds of ignition
being turned on).

DTC 54 – Left Hand Pretensioner Circuit Resistance Too Low
Introduction
This test is used by the technician to aid in the diagnosis of the left-hand pretensioner assembl y.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 54 will set and the airbag warning indicator will illuminate whe n the SDM detects the resistance in the left-
hand pretensioner circuit is too lo w (less than 0.6 ) for longer than 3 – 5 seconds, refer to 2.4 S ystem Self Diagnosis
for more details.
A current DTC 54 will set and the airbag warning indicator will illuminat e whe n circuit 2116 or circuit 2117 (including the
pretensioner assembly) are shorted tog ether.
When DTC 54 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 54. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 54. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 54 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 54 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 54 is set, dependent on where the fault is, the left-hand pretens ioner may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the left-hand pretensioner and associated
components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Checks whether DTC 54 is current or history.
3 Tool No. EL47787 is a dumm y load taking the place of the left-hand pr etensioner assembly. If DTC 54 becomes a
history DTC with the dummy load connected, the system fault is in the left-hand pretensio ner assembly.
4 Checks for a short-circuit between circuit 2116 and circuit 2117. Isolates whether there is a short-circuit between
circuit 2116 and 2117, or the SDM is at fault.

DTC 247 – Left Hand Pretensioner Circuit Power Stage Error
Introduction
This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self-test the SDM detects a fault with the left-hand pretensioner circuit power stage, a current DTC 247 Left Hand
Pretensioner Circuit Power Stage Error will set. On completion of the initial system self-test, the SDM then performs a
test of the left-hand pretensioner circuit. If the SDM detects a problem with this circuit, the associated left-hand
pretensioner circuit DTC will set and DTC 247 Left Hand Pretensioner Circuit Power Stage Error will become a history
DTC.
DTC 247 Left Hand Pretensioner Circuit Power Stage Erro r will set if a fault occurs in the left-hand pretensioner with the
in-built capacitor, connector Y129 – X1, the OPS wiring harness, connector A65 – X1 or the SDM.
When a history DTC 247 Left Hand Pretensioner Circuit Power Stage Error sets, the SDM illuminates the airbag warning
indicator. Should the fault conditions detected b y the SDM clear during the same ignition cycle, the code will remain a
history DTC 247 Left Hand Pretensioner Circuit Power Stage Error for all ignition cycles until cleared. The airbag warning
indicator will remain on for the remainder of the ignition cycle.
When DTC 247 Left Hand Pretensioner Circuit Power Stage Error sets, the SDM illuminates the airbag warning indicator
for the remainder of the ignition cycle. Should the fault conditions detected by the SDM clear during the same ignition
cycle, the code will remain a histor y DTC 247 Left Hand Pretensioner Circuit Power Stage Error for all ignition cycles until
cleared. The airbag warning indicator will also remain illuminated until the history DTC 247 Left Hand Pretensioner
Circuit Power Stage Error is cleared.
If DTC 247 Left Hand Pretensioner Circuit Power Stage Error is set, dependent on where the fault is, the left-hand
pretensioner may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the left-hand pretensioner and associated
components.
Action Required
If DTC 247 Left Hand Pretensioner Circuit Power Stage Error and any other DTC are set then the diagnostics for the
other DTC should be carried out first. For example if DTC 247 Left Hand P r etensioner Circuit Power Stage Error and
DTC 53 are set, the diagnostics for DTC 53 should be carried out first.
If only DTC 247 Left Hand Pretensioner Circuit Power Stage Error is set, the SDM should be replaced.
NOTE
An intermittent fault in the left-hand pretensioner
circuit may cause DTC 247 Left Hand
Pretensioner Circuit Power Stage Error to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. airbag warning indicator not illuminated after 5 seconds of ignition
being turned on).

DTC 70 – Right Hand Pretensioner Circuit Resistance Too Low
Introduction
This test is used by the technician to aid in the diagnosis of the right-hand p retensioner assembly.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
SDM performs a system self check.
A current DTC 70 will set and the airbag warning indicator will illuminate when the SDM detects the resistance in the
right-hand pretensioner circuit is too lo w (less than 0.6 ) for longer than 3 – 5 seconds, refer to
2.4 System Self Diagnosis for more details.
A current DTC 70 will set and the airbag warning indicator will illuminat e whe n circuit 2118 and circuit 2119 (including the
pretensioner assembly) are shorted tog ether.
When DTC 70 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 70. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 70. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 70 is set, the airbag warning indicator will illuminate on each ignition cycle (even if the DTC is set as a history
DTC) until the fault conditions for setting DT C 70 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 70 is set, dependent on where the fault is, the right-hand pretensio ner may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the right-hand pretensioner and associated
components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Checks whether DTC 70 is current or history.
3 Tool No. EL47787 is a dumm y load taking the place of the right-hand pretensioner assembly. If DTC 70 becomes a
history DTC with the dummy load connected, the system fault is in the right-hand pretens ioner assembly.
4 Checks for a short-circuit between circuit 2118 and circuit 2119. Isolates whether there is a short-circuit between
circuit 2118 and 2119, or the SDM is at fault.

DTC 247 – Right Hand Pretensioner Circuit Power Stage Error
Introduction
This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self-test the SDM detects a fault with the right-hand pretensioner circuit power stage, a current DTC 247 Right Hand
Pretensioner Circuit Power Stage Error will set. On completion of the initial system self-test, the SDM then performs a
test of the right-hand pretensioner circuit. If the SDM detects a problem with this circuit, the associated right-hand
pretensioner circuit DT C will set and DTC 247 Right Hand Pretensioner Circuit Power Stage Error will become a history
DTC.
DTC 247 Right Hand Pretensi oner Circuit Power Stage Error will set if a fault occurs in the right-hand pretension er,
connector Y128 – X1, the wiring harness, connector A65 – X1 or the SDM.
When a history DTC 247 Righ t Hand Pretensioner Circuit Power Stage Error sets, the SDM illuminates t he airbag
warning indicator. Should the fault conditions detected by the SDM clear during the same ignition cycle, the code will
remain a history DTC 247 Right Hand Pretensioner Circu it Power Stage Error for all ignition cycles until cleared. The
airbag warning indicator will remain on for the remainder of the ignition cycle.
When DTC 247 Right Hand Pretensi oner Circuit Power Stage Error sets, the SDM illuminates the airbag warning
indicator for the remainder of the ignition cycle. Should the fault conditions detected by the SDM clear during the same
ignition cycle, the code will remain a history DTC 247 Right Hand Pretensioner Circuit Power Stage Error for all ignition
cycles until cleared. The airbag warning indicator will also remain illuminated until the history DTC 247 Right Hand
Pretensioner Circuit Power Stage Error is cleared.
If DTC 247 Right Hand Pretensioner Circuit Power Stage Error is set, dependent on where the fault is, the right-hand
pretensioner may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the right-hand pretensioner and associated
components.
Action Required
If DTC 247 Right Hand Pretensioner Circuit Power Stage Error and any other DTC are set then the diagnostics for the
other DTC should be carried out first. For example if DTC 247 Right Ha nd Pretensioner Circuit Power Stage Error and
DTC 69 are set, the diagnostics for DTC 69 should be carried out first.
If only DTC 247 Right Hand Pretensioner Circuit Power Stage Error is set then replace the SDM.
NOTE
An intermittent fault in the right-hand pretensioner
circuit may cause DTC 247 Right Hand
Pretensioner Circuit Power Stage Error to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. airbag warning indicator not illuminated after 5 seconds of ignition
being turned on).

Introduction
This test is used by the technician to aid in the diagnosis of the left-hand side-impact inflatable restraint assembly
positive power supply circuits.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
inflatable restraint control module (SDM) per forms a system self check.
If the SDM detects a resistance to battery supply is less than 5 k in either the positive and/or negativ e circuit for mo re
than 3 – 5 seconds, a current DTC 81 will set, refer to 2.4 System Self Diagnosis for more details.
DTC 81 will set if circuits 2137 (side-impact in flatable restraint, positive side) and/or 2138 (side-impact inflatable restraint,
negative side) are shorted to battery positive.
When DTC 81 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 81. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 81. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 81 is set, the airbag warning indicator will illuminate on each ignition cycle, even if the DTC is set as a history
DTC, until the fault conditions for setting DTC 81 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.

DTC 247 – Left Hand Side Airbag Circuit Power Stage Error
Introduction
This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self test the SDM detects a fault with the left-hand side-impact inflatable restraint assembly circuit po wer stage a current
DTC 247 Left Hand Side Airbag Circuit Power Stage Error will set. On completion of the initial system self test the SDM
then performs a test of the left-hand side-impact inflatabl e restraint assembly circuit. If the SDM detects a problem with
this circuit the associated left-hand side-imp act inflatable restraint assembly circuit DTC will set and DTC 247 Left Hand
Side Airbag Circuit Power Stage Error will become a history DTC.
DTC 247 Left-hand Side-impact Airbag C ircuit Power Stage Error will set if a fault occurs in the left-hand side- impact
inflatable restraint assembly, connector A96L – X1 with the in-built capac itor, connector X306, the OPS wiring harness,
connector A65 – X1 or the SDM.
When a history DTC 247 Left Hand Side A irb ag Circuit Power Stage Error sets, the SDM illuminates the airbag warning
indicator. Should the fault conditions detected b y the SDM clear during the same ignition cycle the code will remain a
history DTC 247 for all ignition cycles until cleared. The airbag warning indic ator will also remain illuminated for the
remainder of the ignition cycle.
When DTC 247 Left Hand Side Airb ag Circuit Power Stage Error sets, the SDM illuminates the airbag warning indicator
for the remainder of the ignition cycle. Should the fault conditions detected by the SDM clear during the same ignition
cycle the code will remain a history DTC 247 for all ignition cycl es until cleared. The airbag warning in dicator will also
remain illuminated until the history DTC 247 Left Hand Side Airba g Circu it Power Stage Error is cleared.
If DTC 247 Left Hand Side Airbag Circuit Power Stage Erro r is set, dependent on where the fault is, the left-hand side-
impact inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the SDM and associated components.
Action Required
If DTC 247 Left Hand Side Airbag Circuit Power Stage Erro r and an y other DTC is set then the diagnostics for the other
DTC should be carried out first. For example if DTC 247 Left Hand Side Airbag Circuit Power Stage Erro r and DTC 85
are set, the diagnostics for DTC 85 should be carried out first.
If only DTC 247 Left Hand Side Airbag Circuit Power Stage Error is set then the SDM should be replaced.
NOTE
An intermittent fault in the left-hand side-impact
inflatable restraint circuit may cause DTC 247
Left Hand Side Airbag Circuit Power Stage Error
to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. warning indicator not illuminated after five seconds of ignition being
switched on).

DTC 97 – Right Hand Side Airbag Circuit Short to Battery
Introduction
This test is used by the technician to aid in the diagnosis of the right-hand side-impact inflatable restraint assembly
positive power supply circuits.
Circuit Description
With the ignition turned on, and on a constan t monitoring cycle of every 500 milliseconds during the ignition cycle, the
inflatable restraint control module (SDM) per forms a system self check.
If the SDM detects a resistance to battery supply is less than 5 k in either the positive and/or negativ e circuit for mo re
than 3 – 5 seconds, a current DTC 97 will set, refer to 2.4 System Self Diagnosis for more details.
DTC 97 will set if circuits 2135 (side-impact in flatable restraint, positive side) and/or 2136 (side-impact inflatable restraint,
negative side) are shorted to battery positive.
When DTC 97 sets, the SDM illuminates the airbag warning indicator and sets a current D TC 97. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 97. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.
If DTC 97 is set, the airbag warning indicator will illuminate on each ignition cycle, even if the DTC is set as a history
DTC, until the fault conditions for setting DTC 97 are rectified and the DTC (current or hist ory) can then be cleared from
the SDM using Tech 2.
If DTC 97 is set, the OPS, including the right-hand side-impact inflatable restraint assembly, may still be operational due
to the reserve energy supply stored in the SDM.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the right-hand side-impact inflatable
restraint assembly and associated components.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Uses Tech 2 to check whether DTC 97 is current or history.
3 Tool AU485 is a dummy lo ad taking the place of the right-hand side-impact inflatable restraint assembly. If DTC 97
becomes a history DTC with dummy load connected, the system fault is in the side-impact inflatable restraint
assembly.
4 Checks for a short circuit to battery in circuit 2135.
5 Checks for a short circuit to battery in circuit 2136. Isolates whether circuit 2136 or the SDM is at fault.

This test is used by the technician to aid in the diagnosis of the SDM.
Circuit Description
With the ignition turned on, the SDM performs an initial system self check of the SDM power stages. If during this initial
self-test the SDM detects a fault with the right-hand side-impact inflatable restraint assembl y circuit power stage a
current DTC 247 Right Hand Side Airbag Circuit Power Stage Error will set. On completion of the initial system self test
the SDM then performs a test of the right-hand side-impact inflatable restraint circuit. If the SDM detects a problem with
this circuit the associated right-hand side-impact inflatable restraint assembly DTC will set and DTC 247 Right Hand Side
Airbag Circuit Power Stage Error will become a history DTC.
DTC 247 Right Hand Side Airbag Circuit Power Stage Error will set if a fault occurs in the right-hand side-impact
inflatable restraint assembly, connector A96_R – X1 with the in-built capacitor, connector X307, the OPS wiring harness,
connector A65 – X1 or SDM.
When a history DTC 247 Right Hand Side Airbag Circuit Power Stage Error sets, the SDM illuminates the airbag warning
indicator. Should the fault conditions detected b y the SDM clear during the same ignition cycle the code will remain a
history DTC 247 for all ignition cycles until cleared. The airbag warning indic ator will also remain illuminated for the
remainder of the ignition cycle.
When DTC 247 Right Hand Side Airbag Circuit Power Stage Error sets, the SDM illumina t es the airbag warning indicat or
for the remainder of the ignition cycle. Should the fault conditions detected by the SDM clear during the same ignition
cycle the code will remain a hi story DTC 247 Right Hand Side Airbag Circu it Power Stage Error for all ignition cycles until
cleared. The airbag warning indicator will also remain illuminated until the history DTC 247 Right Hand Side Airbag
Circuit Power Stage Error is cleared.
If DTC 247 Right Hand Side Airbag Circuit Power Stage is set, dependent on where the fault is, the right-hand side-
impact inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the SDM and associated components.
Action Required
If DTC 247 Right Hand Side Airbag Circuit Power Stage Error and any other DTC is set, then the diagnostics for the
other DTC should be carried out first. For example, if DTC 247 Right Hand Side Airbag Circuit Power Stage Error and
DTC 85 are set, the diagnostics for the DTC 85 should be carried out first.
If only DTC 247 Right Hand Side Airbag Circuit Power Stage Error is set then the SDM should be replac ed.
NOTE
An intermittent fault in the right-hand side-impact
inflatable restraint circuit may cause DTC 247
Right Hand Side Airbag Circuit Power Stage
Error to set.
After the fault has been rectified, ensure all OPS component s are reconnected, and enable the SDM. Clear any DTCs,
then verify the correct operation of the system (i.e. warning indicator not illuminated after five seconds of ignition being
switched on).

2.13 Peripheral Acceleration Sensor DTCs
DTC 129 – Left Peripheral Acceleration Sensor Line Fault
Introduction
This test is used by the technician to aid in the diagnosis of the left-hand peripheral acceleration sensor wiring harness.
Circuit Description
The peripheral acceleratio n se nsor communicates continuously with the SDM by modulating the consumed current at a
constant voltage.
If this communication is interrupted or disturbed by a short circuit to ground between the SDM and the left-han d
peripheral acceler ation for lo nger than 3 – 5 seconds, a current DTC 129 is set.
DTC 129 will set if circuit 2132 is shorted to ground.
When DTC 129 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 129. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 129. The airbag warning indicator will remain on for the remainder of the ignition cycle.
If DTC 129 is set, the airbag warning indicat or will illuminate on each ignition cycle, even if the DTC is set as a history
DTC, until the fault conditions for setting DTC 129 are rectified and the DTC (current or history) can then be cleared from
the SDM using Tech 2.
If DTC 129 is set the left-hand side-impact inflatable restraint assembly may not operate.
Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the left-hand peripheral acceleration sensor
and associated components.
Test Description

DTC 130 – Right Peripheral Acceleration Sensor Line Fault
Introduction
This test is used by the technician to aid in the diagnosis of the right-hand peripheral acceleration sensor wiring harness.
Circuit Description
The peripheral acceleratio n se nsor communicates continuously with the SDM by modulating the consumed current at a
constant voltage.
If this communication is interrupted or disturbed by a short circuit to ground, between the SDM and the rig ht-hand
peripheral acceler ation se nsor for longer than 3 – 5 seconds, a current DTC 130 is set.
DTC 130 will set if circuit 2134 is shorted to ground.
When DTC 130 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 130. Should the fault
conditions detected by the SDM clear during the same ignition cycle, the current code will clear and become a history
DTC 130. The airbag warning indicator will remain on for the remainder of the ignition cycle.
If DTC 130 is set, the airbag warning indicat or will illuminate on each ignition cycle, even if the DTC is set as a history
DTC, until the fault conditions for setting DTC 130 are rectified and the DTC (current or history) can then be cleared from
the SDM using Tech 2.
If DTC 130 is set the right-hand side-impact inflatable restra int may not operate.

2.14 Miscellaneous DTCs
DTC 161 – Configuration Mismatch: Too Little or Too Many Loops in OPS
Introduction
NOTE
DTC 161 will only be set and displ ayed b y Tech 2
as a history DTC even if it is current.
NOTE
The instrument cluster must be programmed for
the correct vehicle configuration, refer to
Section 12C Instruments for the procedure on
programming the instrument cluster.
The SDM will set a history DTC 161 because it has been internally configured for a four loop system, for example, but at
the same time has detected a mismatch with the actual ve hicle configuration.
NOTE
Always refer to the latest Holden spare parts
information for the correct part number when
ordering OPS components.
Tech 2 is capable of displa ying the SDM part number. To do this, connect Tech 2 to the DLC, select Diagnosis / Body /
SRS / Turn Ignition On and the system identification screen will display the SDM part number.
Action Required
To diagnose the source of the mismatch, check for other DT Cs set in the system. Rectify faults setting other DTCs, clear
all DTCs from the SDM and retest the s ystem to determine if DTC 161 sets again. If the DTC sets again, install the
correct SDM.

The purpose of the driver's seatbelt buckle warning indicato r switch, H12, is to activate a seatbelt warning indicator
located in the instrument cluster assembly. The in dicator illuminates when the ignition is turned to the ON position and
the seatbelt is disengaged from the buckle.
When the seatbelt is buckled, the warning indicator switch is in an open cir c uit condition and when unbuckled the switch
is in a closed circuit condition.
Tech 2 can be used to check the driver's seatbelt buckle warning indicator switch operation. Tech 2 will only display
Buckled or Un-buckled.
The seatbelt warning indicato r will illuminate for four seconds when the igni tion switch is turned to the ON position,
irrespective of the status of the driver's seatbelt buckle warning indicator switch.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
1 Checks if the seatbelt indicator illuminates when the ignition is turned on. This can indicate either a faulty
instrument cluster assembly or a faulty power circuit.
2 Checks if there is an intermittent fault in the circuit.
3 Checks if there is a faulty power circuit.
4 Checks the operation of the driver's seatbelt buckle warning indicator switch.
5 Checks continuity of circuit 650 (for all non-memory seats).
6 Checks continuity of circuit 151 (only for eight-way memory seats).

3 Service Operations – Inflatable
Restraint and Pretensioner
Assemblies
3.1 Safety Precautions
When performing service on or around
restraint devices or wiring, follow the
procedures listed in this Section to
temporarily disable the SDM. Failure to follow
these procedures could result in possible
restraint device deployment, personal injury
or otherwise unnecessary repairs.
1 Do not use an external battery charger for starting the vehicle.
2 Do not disconnect the battery from the vehicle's electrical s ystem while the eng ine is running.
3 Disconnect the battery from the vehicle's elec trical s ystem before any external battery charging.
4 Do not disconnect or connect the SDM connector with the ignition turned on.
5 Disconnecting the battery will not immed iately deactivate the SDM. A residual energy reserve in the SDM is
incorporated to enable the pr etensioners and inflatable restraint/s to deploy in the event of a battery failure. The
SDM has sufficient power to deploy the pretensioners and inflatabl e restraint/s for up to 10 seconds after the
battery has been disconnected or the ignition turned off. Many of the service operations require disconnection of
the battery to avoid an accidental de ployment of the pretensioners or inflatable restraint/s.
After a Collision
After a collision, OPS components need to be checked for service ability, refer to
1.4 Repairs and Inspections Require d After a Coll ision.
Fasteners
1 When fasteners are removed, always reinstall them in the same location from which they were removed.
2 If a fastener requires replacement, use a fastener with the correct part number for that application. If a fastener with
the correct part number is not available, a fastener of equal size an d strength (or stronger) may be used. The
correct torque value must be used when inst alling fasteners. If these conditions are not adhered to, parts or system
damage could result.
Windshield
The windshield plays an activ e part duri ng the deployment of the instrument panel inflata ble restraint assembly. The
strength of the windshield and its urethane adhesive is critical to ensure the front seat passenger is correctly protected
during deployment, and must be replaced using the correct repair methods and parts. For further information, refer to
Section 1A6 Stationary Windows.
SDM
Take care when handling the SDM. Do not strike or jar the module or body structure adjacent to the module in a manner
which could cause depl oyment of the pretensioner or inflatable restraints. If an SDM is dropp ed from a height greater
than one metre, it must be replaced.
Occupant Protection System Page 12M–140
Page 12M–140
Side-impact Sensor
Take care when handling a side-imp act sensor. Never strike or jar the sensor or body structure adjacent to the sensor i n
a manner which could cause deployment of a side-impact inflatab le restraint. Never carry a side-impact sensor by the
wiring harness leads. If a side-impact sensor is dropped from a height greater than one metre, it must be replaced.
Inflatable Restraint and Pretensioner Assemblies
Refer to Figure 12M – 32 for the following:
1 When carrying a live (undeployed) inflatable restraint assembly, ensure it is pointed away from you. In case of an
accidental deplo yment, the infl atable restraint assembly will then deploy with minimal chance of injury.
2 When placing a live inflatable restraint assembly on a bench or other surface, always face the assembly up, away
from the surface. This is necessary in order to provide free space for the inflatable restraint assembly to expand, in
case of accidental deployment. Also, do not place anything on top of the inflatable restraint assembly.
3 Do not carry a seatbelt pretension er by it's wiring harness lead.
4 Do not apply po wer to an inflatable restraint except as specified in this Sect ion.
5 Do not attempt to make any repairs to the inflatable restraint assembl ies, pretensioners, SDM, or side-impact
sensors. A damaged or defective component must be replaced.
6 Do not weld, solder, braze, hammer, machine, drill, or other wise heat any OPS component.
7 When handling a deployed inflatable restraint assembl y or pr etensioner:
a Always wear gloves and safet y glasses.
b Wash hands with mild soap and water afterwards. The surface of these components may contain chemicals
as a result of the gas generated during combustion which can irritate your skin.
8 When handling a steering co lumn:
a During any service op eration that requires removal and reinstallati on of a steering column fitted with an
inflatable restraint assembly, always carry the steering column with two hands and with the steering wheel
away from your body.
b Do not set a steering column on the floor with the steering wheel facing toward the floor.
During any service operation that requires
removal of a steering column, ensure the
steering shaft is locked to the column to
prevent any possibility of allowing the
steering shaft to rotate and possibly
damaging the clock spring coil ribbon wire.
9 When carrying out steering gear removal and installation procedures, remove the ignition key from the ignition lock
and ensure the steering column is locked. If this operation is not carried out and the steer ing wheel is spun while
the steering gear is removed, the clock spring coil will be destroyed. This will result in the SDM setting a DTC, and
non-deployment of the steering wheel inflatable restraint assembly.
Occupant Protection System Page 12M–141

Figure 12M – 32
OPS Wiring Repairs
Special wiring harness repair procedures have been developed for use on the OPS due to the sensitive nature of the
circuitry. For further information, refer to Section 12P Wiring Diagrams.
NOTE
The pigtail wiring harness that connects the
side-impact inflatable restraint assembly to
the body harness is part of the assembly and
is not serviced separately, due to the design
of the anti-back-out connector on the
inflatable restraint assembly.
If this pigtail wiring harness becomes
damaged, no wire, connector or terminal
repairs are to be attempted. The side-impact
inflatable restraint assembly and pigtail wiring
harness assembly must be replaced.

Disposal Procedure
During the course of a vehicle's useful life, certain situations may arise which will necess itate the disposal of a live
(undeployed) seatbelt buckle and pretensioner assembly. These situations may include damage to the seatbelt buckle
and pretensioner assembly or the assembly being diagnosed as faulty. The following information covers proper
procedures for deployi ng a live assembly.
Failure to follow proper seatbelt buckle
and pretensioner assembly disposal
procedures can result in pretensioner
deployment, which may cause personal
injury.
The seatbelt buckle and pretensioner
assembly must never be deployed inside
the vehicle.
Failure to follow the procedures in the
order listed may result in personal injury.
Read the procedure fully before attempting
to dispose of the seatbelt buckle and
pretensioner assembly. Do not connect
the deployment harness to any power
source before connecting the deployment
harness to the seatbelt buckle and
pretensioner assembly. The deployment
harness must remain shorted and not be
connected to a power source until the
seatbelt buckle and pretensioner assemb ly
is ready to be deployed. The seatbelt
buckle and pretensioner assembly will
immediately deploy when a power source
is connected to it. Wear s afety gl asses an d
gloves throughout this entire deployment
and disposal procedure and follow proper
handling procedures or injury may occur.
The following procedure requires use of
Tool No. J213526-1 deployment harness
with adaptor Tool No. E1992. Do not
attempt this procedure without Tool No.
J213526-1 and T ool No. AU596 as this may
cause the inflatable restraint assembly to
deploy prematurely.
1 Disable the SDM, refer to 3.2 SDM Disabling and Enabling Procedure.
2 Inspect Tool No. J213526-1 d eployment harness and adaptor Tool No. AU596 for damage. If harness or adaptor is
damaged, discard and obtain a replacement.
The deployment h arness must remain sh orted
and not connected to a power source until the
inflatable restraint assembly is to be
deployed. The seatbelt buckle and
pretensioner assembly will immediately
deploy when a power source is connected to
it, refer to Figure 12M – 39.
3 Short the two deployment harness leads together by fully seatin g one banana plug into the other. The deployment
harness must remain shorted and not connected to a power source until the inflatable restraint assembly is to be

3.6 Steering Wheel Inflatable Restraint
Assembly
LT Section No. — 06–225
If conducting the following operation on an
inflatable restraint assembly that has
deployed, wear safety glasses and gloves to
protect your eyes and hands from possible
irritation when handling the deployed
inflatable restraint assembly.
After deployment, the surface of the cushion may contain a powdery residue. This powder consists primarily of
cornstarch (used to lubricate the cushi on) and by-products of the chemical reaction. The by-products of inflatable
restraint assembly module deployment are carbo n monoxide (CO), nitrog en (N), carbon dioxide (CO2), water (H2O) with
trace amounts of oxides of nitrogen (NOΧ) and ammonia (NH 3).
Remove
1 Disable the SDM, refer to 3.2 SDM Disabling and

Safety precautions must be observed
when handling a deployed steering wheel
inflatable restraint assembly. After
deployment, the metal surfaces of the
module will be very hot. Do not touch
these metal areas of the module for about
10 minutes after deployment. Do not place
the deployed steering wheel inflatable
restraint assembly near any flammable
objects. If the deployed steering wheel
inflatable restraint assembly must be
moved before it has cooled, wear gloves
and handle by the inflatable restraint
assembly cushio n o r the trim cover.
Ensure you are wearing safety glasses and
gloves to protect your eyes and hands
from possible irritation and heat when
handling the deployed steering wheel
inflatable restraint assembly.
NOTE
After deployment, the surface of the cushion
may contain a powdery residue. This powder
consists primarily of cor n starc h (used to l ubr icate
the cushion) and by-products of the chemical
reaction. The by-products of inflatable restraint
assembly module deployment are carbon
monoxide (CO), nitrogen (N), carbon dioxide
(CO2), water (H2O) with trace amounts of oxides
of nitrogen (NOΧ) and ammonia (NH3).

Disposal Procedure
During the course of a vehicle's useful life, certain situations may arise which will necess itate the disposal of a live
(undeployed) instrument panel inflatable restraint assembly. T hese situations may include damage to the inflatable
restraint assembly or the assembly being diagn osed as faulty. The following information covers proper procedures for
deploying a live assembly.
Failure to follow proper instrument panel
inflatable restraint assembly disposal
procedures can result in inflatable
restraint assembly deployment, which may
cause personal injury. The undeployed
inflatable restraint assembly contains
substances that can cause severe illness
or personal injury if the sealed container is
damaged during disposal.
The inflatable restraint assembly must
never be deployed inside the vehicle.
Failure to follow the procedures in the
order listed may result in personal injury.
Read the procedure fully before attempting
to dispose of the inflatable restraint
assembly. Do not connect the deployment
harness to any power source before
connecting the deployment harness to the
instrument panel inflatable restraint
assembly. The deployment harness must
remain shorted and not be connected to a
power source until the instrument panel
inflatable restraint assembly is ready to be
deployed. The inflatable restraint
assembly will immediately deploy when a
power source is connected to it. Wear
safety glasses and gloves throughout this
entire deployment and disposal procedure
and follow proper handling procedures or
injury may occur.
The following procedure requires use of
Tool No. J213526-1 deployment harness
with adaptor Tool No. E1992. Do not
attempt this procedure without Tool No.
J213526-1 and Tool No. E1992 as this may
cause the inflatable restraint assembly to
deploy prematurely.

NOTE
The side-impact inflatable restraint assembly
plastic housing has an anti-back-out lug (2)
moulded into it which will prevent the OPS wiring
harness connector (1) from being disconnected.
Due to the in-built capacitor in this connector, a
side-impact inflatable restraint assembly cannot
be intentionally deployed with this connector in
the circuit. Therefore, it will be necessary to cut
part of the side-impact inflatable restraint
housing away from the side-impact inflatable
restraint assembly to allow the OPS wiring
harness connector be disconnected.

deployed. The inflatable restraint assembly
will immed iately de ploy w hen a pow er source
is connected to it.
17 Verify the area around the side-impact airbag module
assembly is clear of all people and lo ose or flammable
objects.
18 Verify the side-impact inflatable restraint assembly is
resting with the inflatable restraint assembly cushion
facing up.
19 Notify all people in the immediate area that you intend
to deploy the side-impact inflatable restraint assembly.
The deployment will be accompan ied by an explosion,
which may startle others.
Figure 12M – 71
20 Separate the two banana plugs on the deplo yment
harness.
When the inflatable restraint deploys, the
rapid gas expansio n will create an explo sion.
Notify all people in the immediate area that
you intend to deploy the inflatable restraint.
21 Connect deployment harn ess leads to the power
source to immediately deploy the side-impact
inflatable restraint assembly, refer to Figure 12M – 73.
NOTE
When the inflatable restraint deploys, the
assembly may jump vertically. This is a normal
reaction of the assembly to the force of the rapid
gas expansion inside the inflatable restraint. Figure 12M – 72
Occupant Protection System Page 12M–176

Figure 12M – 73
22 Disconnect the deployment harness from the power source.
23 Short the two deplo yment harness le ads together by fully seating one ba nana plug into the other.
Occupant Protection System Page 12M–177
Page 12M–177
Safety precautions must be observed
when handling a deployed inflatable
restraint assembly. After deployment, the
metal surfaces of the module will be very
hot. Do not touch these metal areas of the
module for about 10 minutes after
deployment. Do not place the deployed
inflatable restraint assembly near any
flammable objects. If the deployed
inflatable restraint assembly must be
moved before it has cooled, wear gloves
and handle by the inflatable restraint
assembly cushio n o r the trim cover.
Ensure you are wearing safety glasses and
gloves to protect your eyes and hands
from possible irritation and heat when
handling the deployed side-impact
inflatable restraint assembly.
NOTE
After deployment, the surface of the cushion
may contain a powdery residue. This powder
consists primarily of cor n starc h (used to l ubr icate
the cushion) and by-products of the chemical
reaction. The by-products of inflatable restraint
assembly module deployment are carbon
monoxide (CO), nitrogen (N), carbon dioxide
(CO2), water (H2O) with trace amounts of oxides
of nitrogen (NOΧ) and ammonia (NH3).
Figure 12M – 74
24 Disconnect the adaptor E1992 from the inflatable restraint assembly as soon as possibl e after deployment. This will
prevent damage to the adaptor or deployment harness. The adaptor and deployment harness are desig ned to be
reused. They should, however, be inspected for damage after each deplo yment and replaced if necessary.
25 Dispose of the deployed steering wheel inflatable restraint assembly throug h normal refuse channels after it has
cooled for at least 10 minutes.
26 Wash your hands with mild soap and water afterward.
