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-52 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.
•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 (unde-
ployed) 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:
Never attempt to measure the resistance of the air bag
(inflator) modules (driver and passenger). It is very dan-
gerous as the electric current from the tester may deploy
the air bag.
WARNING:
For handling and storage of a live air bag (inflator)
module, select a place where the ambient temperature
below 65°
°° °C (150°
°° °F), 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 minimal 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.

AIR BAG SYSTEM 10B-53
LIVE (INACTIVATED) SEAT BELT PRETENSIONER
Special care is necessary when handling and storing a live (inac-
tivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is generated
and the seat belt (1) is retracted into the retractor assembly (2)
quickly.
Note, therefore, that if they activate accidentally, the seat belt pre-
tensioners and other object(s) around them may be thrown
through the air.
•Never attempt to disassemble the seat belt pretensioners
(retractor 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 (inacti-
vated) 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 immedi-
ately 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:
When placing a live air bag (inflator) module on bench or
other surface, always face the bag up, away from the sur-
face. As the live passenger air bag (inflator) module must
be placed with its bag (trim cover) facing up, place it on
the workbench with a slit (1) or use the workbench vise
(2) to hold it securely at its lower mounting bracket (3).
It is also prohibited to place anything on top of the trim
cover and stack air bag (inflator) modules.
This is necessary so that a free space is provided to
allow the air bag to expand in the unlikely event of acci-
dental deployment.
Otherwise, personal injury may result.

WARNING:
Never attempt to measure the resistance of the seat belt
pretensioners. It is very dangerous as the electric current
from the tester may activate pretensioner.

INSPECTION
•Check sensor (1) and its bracket (2) for dents, cracks, defor-
mation or rust.
•Check sensor connector (sensor side and harness side) or
lock mechanism for damage or crack.
•Check connector terminals for bent, corrosion or rust.
•Check sensor for resistance.
