ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
WARNING/CAUTION labels are attached on each part of air bag system components (SDM, air bag (inflator) mod-
ules and seat belt pretensioners). Be sure to follow the instructions.
WARNING:

If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.

Do not modify the steering wheel, dashboard or any other air bag system components. Modifications
can adversely affect air bag system performance and lead to injury.

Failure to follow procedures could result in possible air bag system activation, personal injury or un-
needed air bag system repairs.

Many of service procedures require disconnection of ªAIR BAGº fuse and air bag (inflator) modules (driver and
passenger) from initiator circuit to avoid an accidental deployment.

Do not apply power to the air bag system unless all components are connected or a diagnostic chart requests
it, as this will set a diagnostic trouble code.

The ªAir Bag Diagnostic System Checkº must be the starting point of any air bag diagnostics. The ªAir Bag Diag-
nostic System Checkº will verify proper ªAIR BAGº warning lamp operation and will lead you to the correct chart
to diagnose any air bag malfunctions. Bypassing these procedures may result in extended diagnostic time, incor-
rect diagnosis, and incorrect parts replacements.

Never use air bag component parts from another vehicle.

If the vehicle will be exposed to temperatures over 93
C (200
F) (for example, during a paint baking process),
remove the air bag system components beforehand to avoid component damage or unintended system activa-
tion.

When servicing, if shocks may be applied (eg., dropped from a height of 90 cm (3 ft) or more) to air bag system
component parts, remove those parts beforehand.

When using electric welding, be sure to disconnect air bag (inflator) module and seat belt pretensioner connec-
tors (driver and passenger) respectively.

When applying paint around the air bag system related parts, use care so that the harness or connector will not
be exposed to the paint mist.

Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting) or
flames.
WARNING:
When performing service on or around air bag system components or air bag wiring, follow the proce-
dures listed in the following pages to temporarily disable the air bag system. Refer to appropriate ser-
vice manual procedures. Failure to follow procedures could result in possible air bag system activa-
tion, personal injury or unneeded air bag system repairs.

4) Install glove box.
5) Install ªAIR BAGº fuse to ªAIR BAGº fuse box.
6) Turn ignition switch to ON and verify that ªAIR BAGº warning
lamp flashes 6 times and then turns off.
If it does not operate as described, perform ªAir Bag Diagnostic
System Checkº in this section.
HANDLING AND STORAGE
SDM
WARNING:
Never power up air bag system when SDM is not rigidly at-
tached to the vehicle. Otherwise, personal injury may result.
CAUTION:
After detecting one time of such collision as to meet deploy-
ment conditions, the SDM must not be used.
Refer to ªDiagnosisº when checking the SDM.

Never attempt disassembly of SDM.

When storing SDM, select a place where neither high tempera-
ture nor high humidity is anticipated and oil, water and dust are
kept off.

If SDM was dropped from a height of 90 cm (3 ft) or more or if it
is found to be damaged or deformed, replace it with a new one.

If installation part of SDM was damaged, repair that part com-
pletely before reinstallation.

All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of the ve-
hicle to ensure proper operation of the air bag system.

ACCIDENT WITH OR WITHOUT DEPLOYMENT ± COM-
PONENT INSPECTIONS
Certain air bag and restraint system components must be in-
spected after any crash, whether the air bag deployed or not.
Those components are:

Steering column and shaft joints
± Check for length, damage and bend according to ªChecking
Steering Column for Accident Damageº in SECTION 3C1.

Steering column bracket and capsules
± Check for damage and bent.
If any faulty condition is found in above checks, replace faulty
part.

Steering wheel and driver air bag (inflator) module
± Check for damage or air bag (inflator) module fitness.
± Check trim cover (pad surface) for cracks.
± Check wire harness and connector for damage or tightness.
If any faulty condition is found in above checks, replace faulty
part.

Contact coil and combination switch assembly
± Check wire harness and connectors for damage or tightness.
± Check contact coil case for damage.
If any faulty condition is found in above checks, replace.

Instrument panel member and reinforcement
± Check for any distortion, bending, cracking or other damage.
If any faulty condition is found in above checks, replace.

DEPLOYMENT INSIDE VEHICLE
Use this procedure when scrapping the entire vehicle including the driver and passenger air bag (inflator) modules.
CAUTION:
When vehicle itself will be used again, deploy the air bag outside vehicle according to ªDeployment
Outside Vehicleº, for deploying it inside will cause the instrument panel, glove box and their vicinity
to be deformed.
Failure to observe this CAUTION may require unneeded vehicle inspection and repair.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.

To avoid an accidental deployment, this work should be performed by no more than one person.

The procedure should be followed strictly as described here.

Be sure to read ªService Precautionsº for the air bag (inflator) module beforehand.

Never connect deployment harness to any power source before connecting deployment harness to
the air bag (inflator) module. Deployment harness shall remain shorted and not be connected to a
power source until the air bag is to be deployed.

The air bag (inflator) module will immediately deploy the air bag when a power source is connected
to it. Wear safety glasses throughout this entire deployment and disposal procedure.

Wear suitable ear protection when deploying air bag. Also, advise those who are in the area close to
deployment site to wear suitable ear protection.

Do not deploy driver and passenger air bag (inflator) modules at the same time.
1) Turn ignition switch to ªLOCKº, remove key and put on safety
glasses.
2) Remove all loose objects from front seats and instrument panel.
3) [For driver air bag (inflator) module]
Disconnect contact coil connector (yellow connector) located
near the base of the steering column.
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.
[For passenger air bag (inflator) module]
Remove glove box from instrument panel and disconnect pas-
senger air bag (inflator) module connector (yellow connector).
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.

8) Route deployment harness out the vehicle.
9) Verify that the inside of the vehicle and the area surrounding
the vehicle are clear of all people and loose or flammable ob-
jects.
10) Stretch the deployment harness to its full length 10 m (33 ft).
11) Place a power source near the shorted end of the deployment
harness. Recommended application: 12 Volts minimum, 2
amps minimum. A vehicle battery is suggested.
12) Completely cover windshield area and front door window
openings with a drop cloth, blanket to similar item. This reduces
the possibility of injury due to possible fragmentation of the ve-
hicle's glass or interior.
13) Notify all people in the immediate area that you intend to deploy
the air bag (inflator) module.
NOTE:

When the air bag deploys, the rapid gas expansion will
create a substantial report. Wear suitable ear protection.
Notify all people in the immediate area that you intend to
deploy the air bag (inflator) module and suitable ear
protection should be worn.

After the air bag (inflator) module has been deployed, the
surface of the air bag may contain a powdery residue.
This powder consists primarily of cornstarch (used to lu-
bricate the bag as it inflates) and byproducts of the
chemical reaction.
WARNING:
Safety precautions must be observed when handling a
deployed air bag (inflator) module.

After deployment, the metal surfaces of the air bag (infla-
tor) module will be very hot. Do not touch the metal areas
of the air bag (inflator) module for about 30 minutes after
deployment.

Do not apply water, oil, etc. to deployed air bag (inflator)
module.

If the deployed air bag (inflator) module must be moved
before it is cool, wear gloves and handle by the air bag or
vinyl trim.
Failure to follow procedures may result in fire or personal
injury.
