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 airbag) 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.

Active head restraints that are incorporated in the front seat assemblies are also fitted. For further information on activ e

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 diagnostic module (SDM), which is mounted on the floor panel beneath the centre consol e. 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 emergenc y locking retractor lap-sash seatbelt assembly. The emergency

locking retractor mechanism locks the seatbelt webbing under one or more of the following conditions:

• 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 factors involved, such as size of the obj ect, 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 an y 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 side.

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 Restraints 30 ms

Side-impact Inflatable Restraints 20 ms

Regular maintenance of the OPS is not required. However, if at any time the airbag warning indicator (located on th e

instrument cluster):

• illuminates while driving, or

• does not illuminate when the vehicl e 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 regard ing Tech 2, refer to Section 0C Tech 2.

• 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 with

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 prevailing

conditions and operation.

Occupant Protection System Page 12M–14

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, and the airbag warning indic ator 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 a nd 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 hea d and neck.

4 End of Collision:

• The steering wheel inflatable restraint assembly deflates fully.

prevailing conditions a nd operation.

3 During Restraint:

• The force of the collision causes the head 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 reg ion,

reducing the chest loads and providing support for the head and neck.

4 End of Collision:

• The side-impact inflatable res traint assembly deflates fully.

Figure 12M – 6

Occupant Protection System Page 12M–17

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 inputs.

The SDM is mounted under the floor conso le assembly and

consists of an electronic acceleration sensor system,

electronic control system, and energy storage devices. It's

electronics are capable of self diagnostics, fa ult 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 pretensioner 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 independently 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 electric al 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 acceleration data of

the vehicle. Microprocessors within the 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 p erforms 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 capacitor, 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.

The SDM communicates diagnostic information through the Serial Data Link Connector (DLC) for the following purposes:

• System checks at the vehicle assembly plant.

• Service diagnosis (using Tech 2).

• Transmitting of collision event recording data for post collision analysis.

Page 12M–17

Occupant Protection System Page 12M–18

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 s ystems to take appropriate shutdown action.

The Powertrain Control Module (PCM) or Engine Contro l Module (ECM) monitors this serial data and performs 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 mon itors this serial data and performs the following actions once the appropriate

data is identified and the vehicle 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.

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 acce leration,

recognise a collision, and send a signal 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 – 8

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 br acket assembly on the

same side as the deployed inflatable restraint

must be replaced.

• Figure 12M – 8 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.

Page 12M–18

Occupant Protection System Page 12M–19

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 – 9 for the following.

The pretensioner has an ign iter 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.

When an ignition signal from the SDM is sen t to the igniter, the gas generator is activated driving the retr actor 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 directi on of

deployment, the clamping action of the interlocking cam directly on the cable prevents further movement.

Page 12M–19

Occupant Protection System Page 12M–20

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 outer housing.

• A wiring harness (3) that connects to the steering

wheel inflatable restraint assembly (3A) and the

steering wheel horn bar and remote radio controls

(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 ou ter housing are aligned

to provide approximatel y 2.5 turns of the steerin g

wheel in either direction.

Figure 12M – 10

• 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 anti-clockwise direc tion (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 – 11.

The inflatable restraint assembl y deploys through the steering wheel inflatable restraint trim cover.

Inflator Assembly

Referring to Figure 12M – 12, the inflator assembl y contains the following:

• An Electro Explosive Device (EED) (1). The EED consists of an electrical heating element (called a squib) 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 restraint assembly cushion.

• EED wiring connector pins (6).

Figure 12M – 12

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 styphnate 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 chemical reaction causes the carbon based non-toxic composite propellant to rap idly 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 ma y 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.

Page 12M–21

Occupant Protection System Page 12M–22

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 – 13.

The inflatable restraint assembly deploys through the instrument pan el inflatable restraint opening 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.

Inflator Assembly

Referring to Figure 12M – 14, 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 squib) 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 turbul ence of the gas exiting through the exhaust

ports.

• Burst Disc (5).

• Actuator piston, striking primers and enha ncer pack (6)

• Hybrid propellent (7).

• Radial holes (8), which allow the gases to flow throughout the assembly.

• Argon gas (9).

Page 12M–22

Occupant Protection System Page 12M–23

Figure 12M – 14

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 assembl y

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 generated 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 p osition the inflatable restraint assembly cushion. In some deployment conditions,

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 ma y 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

restraint assembly are not repairable. Under

no circumstances are the components of the

side-impact inflatable restrain t assembl y to b e

disassembled. The inflatable restraint

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 traint assembly contains five main components, refer to Figure 12M – 15.

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.

Inflator Assembly

Referring to Figure 12M – 16, the inflator assembl y contains the following:

• A small amount of oxidiser (1).

• A small amount of fuel (ethanol) (2).

• Compressed inert gas (t ypicall y 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

pyrotechnical charge.

• Burst Discs (5) and (6).

• Diffuser (7), which is a hollow circular mesh that reduces the turbul ence of the gas exiting through the exhaust

ports.

• Exhaust ports (8).

Figure 12M – 16

Page 12M–24

Occupant Protection System Page 12M–25

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.

Airbag Warning Indicator

The airbag warning indicator is located in the instrument

cluster.

Legend

1 Airbag Warning Indicator (Airbag Warning Lamp)

2 Multi Function Display (MFD)

3 Seatbelt Warning Indicator

Figure 12M – 17

The airbag warning indicator is controlled by the SDM using the serial data circuit and will illuminate to warn the driver

the system has been disabled or there is a fault in the system.

The airbag warning ind icator will illuminate whe n:

• The ignition is switched on. The airbag warning indicator will be illuminated for approximately five seconds to

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 ignitio n is first switched on

and then commanded on constantl y until th e fault is remedied (communication resumed) (No DTC will set).

• If an inflatable restraint assembly and/or pr etensioner is deployed, the airbag warning indicator will be illuminated

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 and rema in illuminated until the DTC 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 illumi nated. 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 ill uminated 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 – 17.

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 circuit.

For more information, refer to Section 12C Instruments.

Page 12M–25

Occupant Protection System Page 12M–26

Chime Alert

The airbag warning ind icator and MFD are complemented by a warning chime to alert the driver audibly of a possible

fault with the system.

The warning chime alert is controll ed 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 – 17, uses a ground circuit provided by the driver’s seatbelt buckle

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 d uring this period, the indicator will flash for a further

90 seconds at which point it will extinguish, e ven if the seatbelt is not fastened.

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 agai n, 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 no t

inserted into the buckle. When the seatbelt is inserted i nto 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.

Warning Labels

In order to provide adequate warning of the OPS operation and service requirement to the vehicle's owner, driver or

service technicians, OPS warning labels are located on various comp onents of the vehicle, refer to Figure 12M – 18.

NOTE

If at any time any these components are

replaced, ensure the appropriate warning label is

applied to the replacement part.

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 – 19 illustrates the wiring harness connector

with an in-built capacitor. The connector consists of:

• Capacitor (1).

• Service holes to aid in diagno sis of the system (2).

• Connector Pins (3).

Occupant Protection System Page 12M–29

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 suppl y the inflatable restrain t assembly with an AC supply when the SDM

senses an impact that requires deployment of the restraint assembly. T he '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 – 20, which shows the steering wheel

inflatable restraint assembly wiring diagram. All

firing loops function in the sa me manner.

The ‘H’ bridge has two sources of supply; the internal capacitor (ER) of the SDM, which is the energy reserve supply,

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 deployment.

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 reserve is not available for any reason when firing is required,

only battery voltage at the power stage is present, and firing occurs immediately with Firing Mode 3.

Page 12M–29

Occupant Protection System Page 12M–30

Firing Mode 1

Firing Mode 1 is designed to activate the initi ator (1) in the ev ent the negative side of the firing loop (circui t 3020) is

shorted to ground or battery, refer to Figure 12M – 20. T hroughout 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 a nd S2 closes providing a ground circuit for the positive side of the firing loop.

The charging and disc harging (the opening and clos ing 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 – 20

Page 12M–30

Occupant Protection System Page 12M–31

Firing Mode 2

Firing Mode 2 is designed to activate the initi ator (1) in the ev ent the positive side of the firing loop (circuit 302 1) is

shorted to ground or battery, refer to Figure 12M – 21. T hroughout 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) throu gh

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 – 21

Page 12M–31

Occupant Protection System Page 12M–32

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 – 22. During this cycle, S3 is closed, providing a ground for circuit 302 0. S2 and S4 are both open.

When discharging (B), S4 is closed allowing both battery and ER po wer through the ne gative side (circuit 3020). During

this cycle, S2 is closed, providing a ground for circuit 3021. S1 and S3 are both open

The charging and disc harging (the opening a closing of S1 and 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 – 22

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 grou nd or battery voltage.

• Short circuit or shunt circuit between firing lea ds of the firing loop.

• Resistance of the initiator too high or too lo w.

• Capacitance of the firing lo op capacitor too high or too lo w.

When the SDM detects any of the above faults, it will produce a Diagn ostic Trouble Code (DTC) and illum inate the airbag

warning indicator. For further details refer to 2 Diagnostics.

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 th e diagnostic 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 S ystem (OPS) the technicia n must have a g ood 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 troublesh ooting procedures and hints of the use of circuit testing tools are

covered in Section 12P Wiring Diagrams.

Page 12M–35

Occupant Protection System Page 12M–36

The technician should understand the following:

• The meaning of voltage (V), current (A), and resistance (Ω),

• basic theory of electricity, direct current (DC) theory, series and p arallel circuits, and voltage drops across series

resistors,

• alternating current (AC) theory including in ductance, capacitance and im pedance,

• 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 illumi nated and an airbag fault message is displayed by

the Multi Function Display (MFD) located in the instrument cluster. Depending on the fault, the SDM may disable the

inflatable restraint and pretensioner assemblies.

If present, diagnosable system faults are detected by the SDM during an initialisation 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 permanently 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 memor y 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 a r e not met.

Current DTCs can be cleared (changed to history DTC) by removing the fault conditions.

Tech 2 is unable to clear current DT Cs if the fault conditions still exist; Tech 2 will displa y Clear DTC Information

Failed.

DTCs stored in the SDM memory can only be displayed 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 by 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.

Page 12M–43

Occupant Protection System Page 12M–44

2.6 Electrical Diagnosis

Introduction

The following diagnostic tables are designed to aid fast and efficient fault location and remedy. The diagnostic 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, ref er 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 connections, use the adapters 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 dama ging wiring harness pins which

may cause a system intermittent failure.

Figure 12M – 25 illustrates the correct use and instal lation of the various diagnostic tools (Tool No. SD282 80B, Tool No.

AU485, Tool No. EL47787 an d 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 procedure, all diagnostic tools are removed and al l OPS components 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 data bus, instructs the

instrument cluster to illuminate the airbag 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 DTC has been set causing the airbag warning indicator to remain

illuminated.

Airbag Warning Indicator Inoperative

Introduction

This test is used by the technician to aid in d iagnosis when the air bag warning indicator is inoperative.

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 exting uished by serial data from the SDM.

The airbag warning indicator will illuminat e:

• When the ignition is turned to the ON position (s ystem 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 instrument 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.

Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the airbag warning indicator and associated

components.

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 and 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 c ommunication, 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 ignitio n cycle), the airbag warning indicator 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 a n

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 (s ystem 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 instrument 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 also 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. D uring this chec k, the SDM through the

serial data bus, instructs the instrument cluster to illuminate the airbag 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 DTC 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 activ ated. If the voltage supp ly 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.

Assembly DTCs

DTC 17 – Driver Airbag Circuit Short to Battery

Introduction

This test is used by the technician to aid in diagnosis when DTC 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 kΩ in eith er the positive and/or the negative circuit for more than 3 – 5 seconds.

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 DTC 17. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle (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 circuits.

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 kΩ in eit her the positive or negative inflator circuit for more than 3 – 5 seconds, 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

shorted to ground.

When DTC 18 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 18. Should the fault

conditions detected by the SDM clear dur ing the same ignition cycle, the current code will clear and become a history

DTC 18. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.

If DTC 18 is set, the airbag warning indicato r will illuminate on each ignition c ycle (even if the DTC is set as a history

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 bly 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 DTC 19. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle (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 oper ate. The clock spring coil assembly must

be replaced as connector A106 – X1, with the in-built cap acitor, is part of the clock spring coil assembly. Refer to

3.7 Clock Spring Coil Assembly for the correct procedure on replacing the clock 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 DT Cs, then verify the correct operation of the s ystem (i.e. airbag warning indicator not illuminated

after 5 seconds of ignition being turned 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 assembly 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 DTC 20. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle, 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.

Action Required

If DTC 20 is set, the steering wheel inflatable restraint assembly may not oper ate. The clock spring coil assembly must

be replaced as connector A106 – X1, with the in-built cap acitor, is part of the clock spring coil assembly. Refer to

3.7 Clock Spring Coil Assembly for the correct procedure on replacing the clock spring coil assembly.

After the clock spring coil assembly has been replaced, ensure all OPS components are reconnected, and enable the

SDM. Clear any DTCs, then verify the correct operatio n of the system (i.e. airbag warning indicator not illuminated after

5 seconds of ignition being turned on).

Occupant Protection System Page 12M–58

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 bly circuit is too high (greater than 8.4 Ω) 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 bly and the clock spring coil) are open-circu it.

When DTC 21 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 21. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle (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 inflatabl e 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 togeth er, 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 bly circuit is too low (less than 1 Ω) 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 assembly and the clock spring coil) ar e shorted together.

When DTC 22 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 22. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle (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 inflatabl e 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 DT C 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 assemb ly 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 ignitio n cycle, the

code will remain a history DTC 247 Driver Airbag Circuit Po wer Stage Error for all ignition cycles until cleared. The 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 components are reconnected, and enab le 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).

battery positive is less than 5 kΩ in eith er the positive and/or negative circuit for more than 3 – 5 seco nds, refer to

2.4 System Self Diagnosis for more details.

A current DTC 33 will set and the airbag warning indicator will illuminat e whe n circuit 3025 and/or circuit 3024 are

shorted to battery positive.

When DTC 33 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 33. Should the fault

conditions detected by the SDM clear dur ing the same ignition cycle, the current code will clear and become a history

DTC 33. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.

If DTC 33 is set, the airbag warning indicato r will illuminate on each ignition c ycle (even if the DTC is set as a history

DTC) until the fault conditions for setting DT C 33 are rectified and the DTC (current or hist ory) can then be cleared from

the SDM using Tech 2.

If DTC 33 is set, the instrument panel inflatable restraint assembly will still be operational due to the reserve energ y

supply stored in the SDM.

Refer to 2.2 Wiring Diagram and 2.3 Connec tor Chart to aid in diagnosis of the instrument pane l inflatable restraint

DTC 38 – Passenger Airbag Circuit Resistance Too Low

Introduction

This test is used by the technician to aid in the diagnosis of the instrument panel 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 38 will set and the airbag warning indicator will illuminate when the SDM detects the resistance in the

instrument panel inflatable res t raint assembly circuit is too low (less than 0.6 Ω) for longer than 3 – 5 seconds.

A current DTC 38 will set and the airbag warning indicator will illuminat e whe n circuit 3025 or circuit 3024 (including the

instrument panel inflatable res t raint assembly) are shorted together.

When DTC 38 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 38. Should the fault

conditions detected by the SDM clear dur ing the same ignition cycle, the current code will clear and become a history

DTC 38. The airbag warning i ndicator will remain on for the remainder of the ignition cycle.

If DTC 38 is set, the airbag warning indicato r will illuminate on each ignition c ycle (even if the DTC is set as a history

DTC) until the fault conditions for setting DT C 38 are rectified and the DTC (current or hist ory) can then be cleared from

the SDM using Tech 2.

If DTC 38 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 instrument pane l inflatable restraint

assembly and associated components.

Test Description

The following numbers refer to the step numbers in the diagnostic table:

2 Checks whether DTC 38 is current or history.

3 Tool No. SD28280B is a dum my load taking the place of the instrument panel inflatable restraint assembly. If

DTC 34 becomes a histor y DTC with the dummy load connected, the system fault is in the instrument panel

inflatable restraint assembly.

4 Checks for a short-circuit in between circuit 302 5 and circuit 3024. Isolates whether there is a short-circuit between

circuit 3025 and 3024, or the SDM is at fault.

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 illuminates the airbag warning

indicator. Should the fault conditions detecte d by 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 airbag warning indicator for

the remainder of the ignition cycle. Should th e fault conditions detected by the SDM clear during the same ignition cycl e,

the code will remain a history DT C 247 Passenger Airbag Circuit Power Stage Error for all ignition cycles until cleared.

The airbag warning ind icator will also remain illumin ated until the history DTC 247 Passenger Airbag Circuit Power Stage

Error is cleared.

If DTC 247 Passenger Airbag Circuit Power 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 components are reconnected, and enab le 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).

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 low (less than 0.6 Ω) for longer than 3 – 5 secon ds, 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 DTC 54. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle (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.

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 s ystem 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 DT C will set and DTC 247 Left Hand Pretensioner Circuit Po wer Stage Error will become a history

DTC.

DTC 247 Left Hand Pretensioner Circuit Power Stage Error 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 detecte d by 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. T he 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 Han d 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 components are reconnected, and enab le 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 – 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 s ystem 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 Cir c uit 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 the 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. T he

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 i nd icator will also remain illuminated until the histo ry 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 components are reconnected, and enab le 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).

NOTE

Due to the design of the anti-back-out connector

A96_L – X1 on the sid e-impact inflatable res traint

assembly, the connector cannot be disconnected

from the side-impact inflatable restraint assembly

without damaging the assembly. Therefore,

repairs to the OPS pigtail wiring harness that run

through the front seat are not to be attempted

(this includes the capacitor in connector A96_L –

X1). If this pigtail har ness is d amag ed in an y way,

the harness and side-impact inflatable restraint

DTC 81 – Left Hand Side Airbag Circuit Short to Battery

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 kΩ in either the positive and/or negative circuit for more

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 inflatable restraint, positive side) and/or 2138 (side-impact inflatable restrai nt,

negative side) are shorted to battery positive.

When DTC 81 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 81. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle, 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.

If DTC 81 is set, the OPS, including the left-hand side-impact inflatable restraint assembly, may still be operational d ue 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 left-hand side-impact inflatable restraint

assembly and associated components.

Test Description

The following numbers refer to the step numbers in the diagnostic table:

2 Checks whether DTC 81 is current or history.

3 Tool AU485 is a dummy load taking the place of the left-hand side-impact inflatable restraint assembly. If DTC 81

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 2137.

5 Checks for a short circuit to battery in circuit 2138. Isolates whether circuit 2138 or the SDM is at fault.

Introduction

This test is used by the technician to aid in the diagnosis of the left-hand side-impact inflatable restraint assembly

positive and negative 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.

A current DTC 82 will set and the airbag warning indicator will illuminate when the SDM detects the resistance to ground

is less than 3 kΩ in either the positive or negative inflator circuit for more than 3 – 5 seconds.

A current DTC 82 will set and the airbag warning indicator will illuminat e whe n circuit 2137 and/or circuit 2138 are

shorted to ground.

When DTC 82 sets, the SDM illuminates the SRS warning indicator and sets a current DTC 82. Should the fault

conditions detected by the SDM clear dur ing the same ignition cycle, the current code will clear and become a history

DTC 82. The SRS warning indicator will remain on for the remainder of the ignition cycle.

If DTC 82 is set, the SRS warning indicator will illum inate on each ignition cycle, even if the DTC is set as a history DTC,

until the fault conditions for setting DTC 82 are rectified a nd the DTC (current or history) can then be cleared from the

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 power 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-impact 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 capacitor, connector X306, the OPS wiring harness,

connector A65 – X1 or the SDM.

When a history DTC 247 Left Hand Side A irbag Circuit Power Stage Error sets, the SDM illuminates the airbag warning

indicator. Should the fault conditions detecte d by 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 cycles until cleared. The airbag warning in dicator will also

remain illuminated until the history DTC 247 Left Hand Side Airbag Circuit 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 Po wer Stage Erro r and DTC 85

are set, the diagnostics for DTC 85 should be carried o ut 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 components are reconnected, and enab le 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 kΩ in either the positive and/or negative circuit for more

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 inflatable restraint, positive side) and/or 2136 (side-impact inflatable restrai nt,

negative side) are shorted to battery positive.

When DTC 97 sets, the SDM illuminates the airbag warning indicator and sets a current DTC 97. Should the fault

conditions detected by the SDM clear dur ing 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 indicato r will illuminate on each ignition c ycle, 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 d ue

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

DTC 247 – Right 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 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 Righ t Hand Side Airbag Circuit Power Stage Error sets, the SDM illuminates the airbag warning

indicator. Should the fault conditions detecte d by 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 tes 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 hi story DTC 247 Right Hand Side Airbag Circuit Power Stage Error for all ignition c ycles 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.

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 consume d current at a

constant voltage.

If this communication is interrupted or disturbed by a short circuit to ground between the SDM and the left-hand

peripheral acceler ation for longer 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 indic ator and sets a current DTC 129. Should the fault

conditions detected by the SDM clear dur ing 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

The following numbers refer to the step numbers in the diagnostic table:

2 Checks whether DTC 129 is current or histor y.

3 Checks for short to ground in circuit 2132 .

4 Swapping the left-hand periph eral acceleration sensor with a known good one (right-hand peripheral acceleration

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

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 un necessary 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 electrical system 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 Required

After a Collision.

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 fast ener of equal size and strength (or stronger) may be used. The

correct torque value must be used when inst alling fasteners. If these conditions are not ad hered to, parts or system

damage could result.

Windshield

The windshield plays an activ e part during the deployment of the instrument panel inflatable restraint assembly. The

strength of the windshield and its urethane adhesive is critic al 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.

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 inflatable 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.

Page 12M–137

Occupant Protection System Page 12M–138

Inflatable Restraint and Pretensioner Assemblies

Refer to Figure 12M – 29 for the following:

1 When carrying a live (undeployed) inflatable restraint assembly, ensure it is pointed away from you. In case of an

accidental deployment, the infl atable restraint assembly will t hen 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 power to an inflatable restra int 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 assembly or pretensioner:

a Always wear gloves and safet y glasses.

b Wash hands with mild soap and water after wards. The surface of these co mponents may contain chemicals

as a result of the gas generated during combustion which can irritate your skin.

8 When handling a steering column:

a During any service operation 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 pr ocedures, remove the ignition key from the ignition lock

and ensure the steering column is locke d. 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.

OPS Wiring Repairs

Special wiring harness rep air 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.

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 an d pretensioner as sembly

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

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. T his powder consists primarily of cornstarch

(used to lubricate 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 (N H3).

Remove

1 Disable the SDM, refer to 3.2 SDM Disabling and

Enabling Procedure.

If the steering wheel inflatable restraint

module is to be removed without removing

the steering column covers, then wrap Tool

No. AU595 with a rag or tape to ensure the

steering column co vers do not get scratched.

2 Rotate the steering wheel 90 degrees from the

straight-ahead position to expose two of the four

access aperture holes in the rear of the steering wheel

hub.

3 Fit Tool No. AU595 into the apertures and pivot the

tool toward the instrument panel to move the tangs of

the tool in an outward direction. This will relieve the

tension on the spring-loaded retaining clips. The

inflatable restraint assembly will move slig htly away

from the steering wheel.

Figure 12M – 38

4 Rotate the steering wheel 180 degrees to expose the remaining t wo access aperture holes. Repeat Step 3.

When removing a steering wheel inflatable

assembly connector (2) from the rear of assembly.

• When carrying a live (undeployed)

steering wheel inflatable restraint

assembly, make sure the trim cover is

pointed away from you. In case of an

accidental deployment, the inflatable

restraint cushion will then deploy with

minimal chance of injury.

• When placing a live steering wheel

inflatable restraint assembly on a bench

or other surface, always face the trim

cover up, away from the surface. This is

necessary so that a free space is provided

to allow the inflatable restraint assembly

cushion to expand in the unlikely event of

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 diagnosed 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.

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. E1992 for damage. If the harness or

adaptor is damaged, discard and o btain a replacement.

The deployment harness must remain shorted

and not connected to a power source until the

inflatable restraint assembly is to be

deployed, refer to Figure 12M – 55. The

inflatable restraint assembly will immediately

deploy when a power source is connected to

it.

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

deployed, refer to F igure 12M – 55.

4 Connect the deployment harness Tool No. J213526–1 (1) to the adaptor Tool No. E1992 (2).

• When storing a live instrument panel

inflatable restraint assembly or when

leaving a live assembly unattended on a

bench or other surface, always face the

assembly with the trim cover up and away

from the surface. This is n ecessary so that

a free space is provided to allow the

inflatable restraint assembly cushion to

expand in the unlikely event of accidental

deployment. Failure to follow procedures

may result in personal injury.

• Ensure other personnel working in the

area are informed where the live inflatable

restraint assembly is and to take care

when working in proximately to the

inflatable restraint assembly.

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 ic ate

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 – 71

24 Disconnect the adaptor E 1992 from the inflatable restraint assembly as soon as possible after deployment. This will

prevent damage to the adaptor or deplo yment harness. The adaptor an d deployment harness are designed to be

reused. They should, however, be inspected for damage after each deployment and replaced if necessary.

25 Dispose of the deployed steering wheel i nflatable restraint assembly through normal refuse channels after it has

cooled for at least 10 minutes.

26 Wash your hands with mild soap and water afterward.
