1. GENERAL DESCRIPTION

The airba g system includes air bags for both th e driver an d

front passenger as well as front seat belt pretensioners

which supplement the seat belts. During a frontal impact

greater than a certain value, the driver airbag (inflator)

module (1) is deployed from the centre of the steering

column, the passenger airbag (inflator) module (2) from the

front passenger side of the instrument panel and the seat

belt pretensioners (3) take-up the slack in the seat belts.

The airbag system is designed to activate only in severe

frontal collisions. It is not designed to activate in rear

impacts, side impacts, rollovers, or minor frontal collisions,

since it would offer no protection in those types of

accidents.

2. DIAGNOSIS

WARNING: To avoid deployment when troubleshooting the airbag system, do not use electrical test

equipment such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electri-

cal equipment other than that specified. Do not use a non-powered probe type tester.

Instructions must be followed carefully, otherwise personal injury may result.

2.1 DIAGNOSTIC TROUBLE CODE (DTC)

The 2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK must always be the starting point of any airbag system

diagnosis. The 2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK checks for proper airbag warning lamp opera-

tion and checks for airbag Diagnostic Trouble Codes (DTCs) using on-board diagnosis function or Tech 2.

2.2 USE OF SPECIAL TOOLS

WARNING: To avoid deployment when troubleshooting the airbag system, do not use electrical test

equipment such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electri-

cal equipment other than that specified in this Service Information. Do not use a non-powered probe

type tester.

Instructions in this Service Information must be followed carefully, otherwise personal injury may

result.

You sh oul d be fam il ia r with the tools li st ed in this Se cti on un der the headi ng 5. SPE CIA L TOOLS . Yo u sh oul d

be a ble to measu re volta ge and resistan ce, and b e fa miliar with th e prop er use of a sc an too l such as air bag

Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.

Special Tool (A) 09932-76010 Connector Test Adapter Kit

must be used whenever a diagnostic procedure requests

checking or probing a terminal.

Using the appropriate adapter in the special tool will ensure

that no damage to the terminal will occur from the

multimeter probe, such as spreading or bending.

An SDM sho rt bar release too l is include d in the connector

test adapter kit.

Inserti ng it in to the SDM conn ec tor will releas e the sh ortin g

bar.

The adapter will also give an idea of whether contact

tension is sufficient, helping to find an open or intermittent

open due to poor terminal contact.

Special tool (B): 09932-75010 airbag driver/passenger load

tool is used only when called for in this Section. It is used

as a diagnostic aid and safety device to prevent inadvertent

airbag (inflator) module deployment.

The load tool has three connectors attached to its case

which are elect rically f unctional and s erve as resisti ve loa d

substitutions.

No more than two connectors are used at any time.

One of connectors (STEERING WHEEL) (2) is used to

substitute the load of followings:

• Driver airbag (inflator) module when it is connected at

the top of the column to the contact coil assembly.

• Passenger airbag (inflator) module when it is

connected to the airbag harness connector for

passenger airbag (inflator) module.

• Each of the driver and passenger seat belt

pretensioners when it is connected to the floor harness

connector for the driver and passenger seat belt

pretensioners.

Another connector (BASE OF COLUMN) (1) is used to

substitute the load of the driver airbag (inflator) module and

the contact coil as sembly whe n it is co nnected at the base

of the column to the airbag wire harness.

The third connector (PASSENGER INFLATOR) (3) is not

used.

By substituting the resistance of the load tool when called

for, a determi nation can be made as to whether an i nflator

circuit component is causing system malfunction and which

component is causing the malfunction.

The load tool should be used only when specifically called

for in the diagnostic procedures.

2.3 INTERMITTENTS AND POOR CONNECTIONS

Most intermittents are caused by faulty electrical

connec tio ns o r wirin g. W hen a c hec k f or pr ope r con nec tio n

is requested in a diagnostic flow table, perform careful

check of suspect circuits for:

• Poor ma ting of conn ector halves, o r terminals no t fully

seated in the connector body (backed out).

• Dirt or corrosion on the terminals. The terminals must

be clean and free of any foreign material which could

impede proper terminal contact.

However, cleaning the terminal with a sand paper or

the like is proh ibit ed .

• Damaged connector body, exposing the terminals to

moisture and dirt, as well as not maintaining proper

terminal orientation with the component or mating

connector.

• Improperly formed or damaged terminals.

Check each connector terminal in problem circuits

carefully to ensure good contact tension by using the

corresponding mating terminal included in the

connector test adapter kit (A) 09932-76010.

If contact tension is not enough, reform it to increase

contact tension or replace.

• Poor terminal -to- wir e co nnecti on.

Check each wire harness in problem circuits for poor

connection by shaking it by hand lightly. If any

abnormal condition is found, change the wire harness

assembly or component parts with new ones.

• Wire insulation which is rubbed through, causing an

intermit tent sh ort as the bare ar ea touc he s othe r wirin g

or parts of the vehicle.

• Wire broken inside the insulation. This condition could

cause a continuity check to show a good circuit, but if

only 1 or 2 strands of a multi-strand-type wire are

intact, resistance could be far too high.

If any abnormality is found, repair or replace as a wire

harness assembly.

2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK

WARNING: To avoid deployment when troubleshooting the airbag system, do not use electrical test

equipment such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of

electrical equipment other than that specified in this Service Information. Do not use a non-powered

probe type tester.

Instructions in this Service Information must be followed carefully, otherwise personal injury may

result.

CAUTION:

The order in which diagnostic trouble codes are diagnosed is very important. Failure

to diagnose the diagnostic troubl e codes in the order specified may result in extended

diagnostic time, incorrect diagnosis and incorrect parts replace ment.

3.1 SERVICE PRECAUTIONS

SERVICE AND DIAGNOSIS

WARNING/CAUTION labels are attached on each part of airbag system components; SDM, airbag (inflator)

modules and seat belt pretensioners. Be sure to follow the instructions.

WARNING:

• If the airbag system and another vehicle system, e.g. ABS, both need repair, to avoid unintentional

airbag system activation the airbag system should be repaired first.

• Do not modify the steering wheel, dashboard, etc. on or around airbag system components.

Modifications can adversely affect airbag system performance and lead to injury.

• Failure to follow proce dures could result in possible airbag system activation, personal injury or

unneeded airbag system repairs.

• Many service procedures require disconnection of the airbag fuse and airbag (inflator) module(s) from the

initiator circuit to avoid an accidental deployment.

• Do not apply power to the airbag system unless all components are connected or a diagnostic chart

requests it, as this will set a Diagnostic Trouble Code (DTC).

• The starting p oint of any airbag diagnostics must be 2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK. This

will verif y proper ai rbag warning la mp ope ration and wi ll lead you to the co rrect table to dia gnose any air-

bag mal function s. Bypass ing these procedur es may result in exte nded dia gnostic ti me, inc orrect d iagno-

sis and incorrect part replacement.

• Never use airbag component parts from another vehicle.

• If the vehicle will be exposed to temperatures over 93°C (for example, during a paint baking process),

remove the airbag system components beforehand to avoid component damage or unintended system

activation.

• When handling the airbag (inflator) modules, seat belt pretensioners or SDM, take care not to drop or

apply an impact to it. If an excessive impact was applied, e.g. the SDM is dropped, an airbag (inflator)

module is dropped from a height of 90 cm or more, a seat belt pretensioner (retractor assembly) is

dropped from a height of 30 cm or more, never attempt disassembly or repair but replace it with a new

one.

• When electric welding, disconnect the airbag (inflator) module connectors and seat belt pretensioner

connectors respectively.

• When applying paint around the airbag system related parts, use care so that the harness or connector

will not be exposed to the paint mist.

• Never expose airbag system component parts directly to hot air (drying or baking the vehicle after

painting) or flam es.

WARNING: When performing service on or around airba g system components or airbag wiring, follow

the procedures listed in the following pages to temporarily disable the airbag system.

Failure to follow procedures could result in possible airbag system activation, personal injury or

unneeded airbag system repairs.

2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK.

HANDLING AND STORAGE

SDM

WARNING:

Never power up the airbag system when

the SDM is not rigidly attached to the vehicle. Other-

wise, personal injury may resul t.

CAUTION:

After detecting one collision that meets

deployment conditions, the SDM must not be used.

Refer to 2.4 AIRBAG DIAGNOSTIC SYSTEM CHECK

when checking the SDM.

• Never attempt disassembly of the SDM.

• When storing the SDM, select a place where neither

high temperature nor high humidity is anticipated and

oil, water and dust are kept off.

• If the SDM has been dropped, replace it with a new

one.

• If the installation part of SDM was damaged, repair that

part completely before reinstallation.

• All SDM and mounting bracket fasteners must be care-

fully torque d and the arr ow mu st b e pointe d towa rd the

front of the vehicle to ensure proper operation of the

airbag system.

Live (undeployed) Airbag (inflator) Modules

Special care is nec essa ry when handli ng an d stor ing a l ive

(undeployed) airbag (inflator) module.

The rapid gas generation produced during deployment of

the airbag could cause the airbag (inflator) module, or an

object in front of the airbag (inflator) module to be thrown

through the air, in the unlikely event of an accidental

deployment.

WARNING:

Never attempt to measure the resistance

of the airbag (inflator) modules as the electric cur-

rent from the tester may deploy the airbag.

• Never attempt disassembly of the airbag (inflator) mod-

ules.

• If any ab normality is found, re place it wi th new one as

an assembly.

• When an abnormality is noted as existing in a live

(undeployed) airbag (inflator) module, deploy it before

discarding it.

• If grease, cleaning agent, oil, water, etc., gets on an

airbag (inflator) module, wipe it off immediately with a

dry cloth.

• If an airbag (inflator) module is dropped from a height

of 90 cm or more, it should be replaced with a new one

as an assembly.

WARNING:

•For handling and storage of a live airbag (inflator)

module, select a pla ce w her e th e ambie nt temp e ra-

ture is below 65°C, without high humidity and away

from electric noise.

• When carrying a live airbag (inflator) module, make

sure the bag opening is pointed away from you. In

case of an accident al deployment, the bag will then

deploy with minimal chance of injury. Never carry

the airba g ( inflator) module by t he wire s or conne c-

tor on the underside of the module, otherwise, per-

sonal injury may result.

WARNING: When placing a live airbag (inflator) module

on a bench or other surface, always face the airbag up,

away f rom the surface. P lace it on a wo rkbench with a

slit (1) or use the workbench vise (2) to hold it securely

at its lower mounting bracket (3).

It is also prohibited to place anything on top of the trim

cover or stack airbag (inflator) modules.

Free space must be provided to allow the airbag to

expand in the unl ikely event of acciden tal deployment ,

otherwise, personal injury may result.

Live (inacti vated) Seat Belt Pretensioner

Special care is nec essa ry when handli ng an d stor ing a l ive

(inactivated) seat belt pretensioner.

When the seat belt pretensioners activate, gas is gener-

ated and the seat belt (1) is retracted into the retractor

assembly (2) quickly.

Note, therefore, that if they activate accidentally, the seat

belt pre tens ioner s and othe r obj ect(s ) ar oun d th em m ay be

thrown through the air.

WARNING:

Never attempt to measure the resistance

of th e s eat b el t pret en sion ers as the el ectric cu rre nt

from the tester may activate pretensioner.

• Never attempt to disassemble the seat belt pretension-

ers (retractor assembly).

• If any ab normality is found, re place it wi th new one as

an assembly.

• When an abnormality is noted as existing in the live

(inactivated) seat belt pretensioner, activate it before

discarding it.

• If grease, cleaning agent oil, water, etc., gets on the

seat belt pre tensioners (retr actor asse mbly), wipe it off

immediately with a dry cloth.

• If a seat belt pretensioner is dropped it should be

replaced with a new one as an assembly.

WARNING:

•For handling and storage of a live seat belt preten-

sioner, select a place where the ambient tempera-

ture is below 65°C (150°F), without high humidity

and away from electric noise.

• Never carry the seat belt pretensioner by the wire

or connector of the pretensioner.

• When placing a live seat belt pretensioner on the

workbench or other surface, do not put anything

on it otherwise, personal injury may result.

Deployed Airbag (inflator) Module and Activated

Seat Belt Pretensioner

WARNING:

• The airbag (inflator) module and seat belt preten-

sioner is very hot immediately after deployment/

activation. Wait for at least 30 minutes for it to cool

before proceeding any work.

• Do not apply water, oil, etc. to a deployed airbag

(inflator) module or an activated seat belt preten-

sioner.

• After an airbag (inflator) module has been

deployed, the surface of the airbag may contain a

powdery residue. This powder consists primarily

of cornstarch (used to lubricate the bag as it

inflates) and by-produc ts of the chemical reaction.

As with many service procedures, gloves and

safety glasses should be worn.

• Wash your hands with mild soap and water after

completing the work.

4.3 DEPLOYED AIRBA G (INFLATOR) MODULE AND ACTIVATED

SEAT BELT PRETENSIONER DISPOSAL

WARNING:

• Failure to follow proper airbag (inflator) module

and seat belt pretensioner disposal procedures

can result in airbag deployment and pretensioner

activation, which may cause personal injury.

• The undeployed airbag (inflator) module and the

inactivated seat belt pretensioner must not be

disposed of through normal refuse channels.

• The undeployed airbag (inflator) module and the

inactivated seat belt pretensioner contains

substances that can cause severe illness or

personal injury if the sealed container is damaged

during disposal.

A deploy ed airbag (infla tor) modu le and activate d seat belt

pretensioner can be disposed of through normal refuse

channels. For disposal the following points should be

noted.

• Immediately after deployment / activation, the airbag

(inflato r) modu le and the seat belt pr etensioner is very

hot. Wait for 30 minutes for it to cool off before handling

it.

• Never app ly water, oil , etc. to a deploy ed airbag (inf la-

tor) module and activated seat belt pretensioner.

• After the airbag (inflator) module has been deployed,

the surface of the airbag may contain a powdery resi-

due. This powder consists primarily of cornstarch (used

to lubricate the bag as it inflates) and by-products of

the chemical reaction. As with many service proce-

dures, wear gloves and safety glasses.

• When disposing of the deployed airbag (inflator) mod-

ule and the activa ted seat belt pretensioner, seal it in

a vinyl bag.

• When an airbag (inflator) module and seat belt preten-

sioner have been deployed / activated inside the vehi-

cle which to be scrapped, leave them installed in the

vehicle.

• Wash your han ds with mi ld so ap and wa ter a fter work

is completed.
