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.

SDM
WARNING:
During service procedures, be very careful when handling
a Sensing and Diagnostic Module (SDM).
Be sure to read ªService Precautionsº in this section before
starting to work and observe every precaution during work.
Neglecting them may result in personal injury or inactiva-
tion of the air bag system when necessary.
REMOVAL
1) Disconnect negative cable at battery.
2) Disable air bag system. Refer to ªDisabling Air Bag Systemº ear-
lier in this section.
3) Remove rear and front center console box by removing screw
and clips.
4) Remove center garnish panel.
5) Remove ashtray and tuner assembly, clock assembly, tuner
pocket, radio hole cover, etc.
6) Disconnect SDM connector from SDM.
7) Remove SDM (with SDM plate) as an assembly from vehicle.
NOTE:
Do not separate SDM and SDM plate.
INSPECTION
CAUTION:

Do not connect a tester whatever type it may be.

Never repair or disassemble SDM.

If SDM was dropped from a height of 90 cm (3 ft) or more,
it should be replaced.

Check SDM and SDM plate for dents, cracks or deformation.

Check SDM connector for damage, cracks or lock mechanism.

Check SDM terminal for bent, corrosion or rust.
If any faulty condition is found in above checks, replace.

PASSENGER AIR BAG (INFLATOR) MODULE
WARNING:

Never attempt to disassemble or repair the passenger air bag (inflator) module. If any abnormality is
found, be sure to replace it with new one as an assembly.

Be sure to read ªService Precautionsº in this section before starting to work and observe every pre-
caution during work. Neglecting them may result in personal injury or undeployment of the air bag
when necessary.
REMOVAL
1) Disconnect negative battery cable at battery.
2) Disable air bag system. Refer to ªDisabling Air Bag Systemº ear-
lier in this section.
3) Open glove box, then while pressing glove box stopper, pull out
glove box from instrument panel.
4) Remove glove box from instrument panel.
5) Remove passenger air bag (inflator) module attaching bolts and
screws, and passenger air bag (inflator) module from vehicle.
WARNING:

When carrying a live air bag (inflator) module, make
sure the bag opening is pointed away from you.
Never carry air bag (inflator) module by wires or con-
nector on the side of the module. In case of an acciden-
tal deployment, the bag will then deploy with minimal
chance of injury.

As the live passenger air bag (inflator) module must be
kept with its bag (trim cover) facing up while being
stored or left standing, place it on the workbench with
a slit or use the workbench vise to hold it securely at its
lower mounting bracket. This is necessary so that a
free space is provided to allow the air bag to expand in
the unlikely event of accidental deployment.

Observe ªService Precautionsº earlier in this section
for handling and storing it.
Otherwise personal injury may result.
