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 93C (200F) (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.

ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
10B-58 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (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 air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.
Never attempt disassembly of the air bag (inflator) modules.
If any abnormality is found, be sure to replace it with new one as
an assembly.
When an abnormality is noted as existing in the live (undeployed)
air bag (inflator) module, be sure to deploy it before discarding it.
When grease, cleaning agent, oil, water, etc., got on the air bag
(inflator) modules (driver and passenger), wipe it off immediately
with a dry cloth.
If air bag (inflator) module was dropped from a height of 90 cm (3
ft) or more, it should be replaced with a new one as an assembly.
WARNING:
For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65C
(150F), without high humidity and away from electric
noise.
When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module.
Otherwise, personal injury may result.

Never attempt to disassemble the seat belt pretensioners (retrac-
tor assembly).
If any abnormality is found, be sure to replace it with new one as
an assembly.
When an abnormality is noted as existing in the live (inactivated)
seat belt pretensioner, be sure to activate it before discarding it.
When grease, cleaning agent oil, water, etc., got on the seat belt
pretensioners (retractor assembly), wipe it off immediately with a
dry cloth.
If seat belt pretensioner was dropped from a height of 30 cm (1
ft) or more, it should be replaced with a new one as an assembly.
WARNING:
For handling and storage of a live seat belt pretensioner,
select a place where the ambient temperature below 65C
(150F), without high humidity and away from electric
noise.
Never carry the seat belt pretensioner by the wires or con-
nector on the underside of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench or some place like that, be sure not to lay it with its
exhaust hole provided side facing down. It is also prohib-
ited to put something on its face with an exhaust hole or
to put a seat belt pretensioner on top of another.
Otherwise, personal injury may result.
