WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adaptor from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

AIR BAG SYSTEM 10B-49
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.

10B-50 AIR BAG SYSTEM
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 from “AIR BAG” fuse box (1).
4) Disconnect Yellow connector (2) of contact coil and combina-
tion switch assembly.
a) Release locking of lock lever.
b) After unlocked, disconnect to connector.
5) Pull out glove box while pushing its stopper from both right
and left sides and disconnect Yellow connector (1) of pas-
senger air bag (inflator) module.
a) Release locking of lock lever.
b) After unlocked, disconnect to connector.
Enabling air bag system
1) Turn ignition switch to “LOCK” and remove key.
2) Connect Yellow connector (1) of contact coil and combination
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 an air bag
system malfunction.
