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)
modules and seat belt pretensioners). Be sure to follow the instructions.
Many of service procedures require disconnection of “AIR BAG” fuse and air bag (inflator) module(s) (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 (DTC).
The “AIR BAG DIAGNOSTIC SYSTEM CHECK” must be the starting point of any air bag diagnostics. The
“AIR BAG DIAGNOSTIC SYSTEM CHECK” will verify proper “AIR BAG” warning lamp operation and will
lead you to the correct table to diagnose any air bag malfunctions. Bypassing these procedures may result
in extended diagnostic time, incorrect 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 pro-
cess), remove the air bag system components beforehand to avoid component damage or unintended sys-
tem activation.
When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver and
passenger) or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was applied
(e.g., SDM is dropped, air bag (inflator) module is dropped from a height of 90 cm (3 ft) or more, seat belt
pretensioner (retractor assembly) is dropped from a height of 30 cm (1 ft) or more), never attempt disassem-
bly or repair but replace it with a new one.
When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passen-
ger) and seat belt pretensioner connectors (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:
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 on or around air bag system compo-
nents. 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
unneeded air bag system repairs.
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.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.

AIR BAG SYSTEM 10B-47
DISABLING AIR BAG SYSTEM
1) Turn steering wheel so that vehicle's wheels (front tires) and
pointing straight ahead.
2) Turn ignition switch to “LOCK” position and remove key.
3) Remove “AIR BAG” fuse (2) from fuse box (1).
4) Disconnect Yellow connector (3) of contact coil and combi-
nation switch assembly.
a) Release locking of lock lever.
b) After unlocked, disconnect connector.
5) If equipped with passenger air bag (inflator) module, pull out
glove box while pushing its stopper from both right and left
sides and disconnect Yellow connector (4) of passenger air
bag (inflator) module.
a) Release locking of lock lever.
b) After unlocked, disconnect connector.
ENABLING AIR BAG SYSTEM
1) Turn ignition switch to “LOCK” position and remove key.
2) Connect Yellow connector (1) of contact coil and combina-
tion switch assembly, and be sure to lock connector with lock
lever.
a) Connect connector.
b) Lock connector with lock lever.NOTE:
With “AIR BAG” fuse removed and ignition switch ON,
“AIR BAG” warning lamp will be ON.
This is normal operation and does not indicate a air bag
system malfunction.

10B-48 AIR BAG SYSTEM
3) If equipped with passenger air bag (inflator) module, connect
Yellow connector (1) of passenger air bag (inflator) module,
and be sure to lock connector with lock lever.
a) Connect connector.
b) Lock connector with lock lever.
4) Install glove box.
5) Install “AIR BAG” fuse to fuse box.
6) Turn ignition switch to ON position and verify that “AIR BAG”
warning lamp flashes 6 times and then turns OFF.
If it does not operate as described, perform “AIR BAG DIAG-
NOSTIC SYSTEM CHECK”.
HANDLING AND STORAGE
SDM
Never attempt disassembly of SDM.
When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
If SDM has been dropped, replace it with a new one.
If installation part of SDM was damaged, repair that part
completely before reinstallation.
All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
WARNING:
Never power up air bag system when SDM is not rigidly
attached to the vehicle. Otherwise, personal injury may
result.
CAUTION:
After detecting one time of such collision as to meet
deployment conditions, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.
