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
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.

AIR BAG SYSTEM 10B-51
DEPLOYED AIR BAG (INFLATOR) MODULE AND ACTI-
VATED SEAT BELT PRETENSIONER
Refer to the procedure described under “DEPLOYED AIR BAG
(INFLATOR) MODULE AND ACTIVATED SEAT BELT PRETEN-
SIONER DISPOSAL”. WARNING:
For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65
°
°° °C (150
°
°° °F), without high humidity and away
from electric noise.
Never carry the seat belt pretensioner by the wire or
connector of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench or other surface, be sure not to lay it with its
exhaust hole (1) provided side facing down. It is also
prohibited to put something on its face with an exhaust
hole (1) or to put a seat belt pretensioner on top of
another.
Otherwise, personal injury may result.
WARNING:
The air bag (inflator) module and seat belt pretensioner
immediately after deployment/activation is very hot.
Wait for at least 30 minutes to cool it off before pro-
ceeding the work.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) module and to activate seat belt pretensioner.
After an air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction. As with many service
procedures, gloves and safety glasses should be
worn.
Wash your hands with mild soap and water after com-
pleting the work.

10B-52 AIR BAG SYSTEM
AIR BAG WIRE HARNESS AND CONNECTOR
Air bag wire harness (1) can be identified easily as it is covered
with a yellow protection tube. Be very careful when handling it.
When an open in air bag wire harness (1), damaged wire
harness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
When installing it, be careful so that the air bag wire harness
(1) is not caught or does not interfere with other parts.
Make sure all air bag system grounding points (2) are clean
and grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent prob-
lems that are difficult to diagnose.
DISPOSAL
Do not dispose of the live (undeployed) air bag (inflator) modules
and the live (inactivated) seat belt pretensioners. When disposal
is necessary, be sure to deploy/activate the air bag and seat belt
pretensioner according to deployment/activation procedure
described in “AIR BAG (INFLATOR) MODULE AND SEAT BELT
PRETENSIONER DISPOSAL”.

Follow this procedure when scrapping the entire vehicle including the air bag (inflator) modules and seat belt
pretensioners.WARNING:
Failure to follow proper air bag (inflator) module and seat belt pretensioner disposal procedures can
result in air bag deployment and pretensioner activation which may cause personal injury.
Undeployed air bag (inflator) module/inactivated seat belt pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and inactivated seat belt pretensioner contain substances
that can cause severe illness or personal injury if the sealed container is damaged during disposal.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.
The procedure should be followed strictly as described here.
Be sure to read “SERVICE PRECAUTIONS” beforehand.
To avoid an accidental deployment, this work should be performed by no more than one person.
Since the smoke is produced when air bag is deployed and pretensioner is activated, select a well-
ventilated area.
The air bag (inflator) module and seat belt pretensioner will immediately deploy/activate when a
power source is connected to it. Wear safety glasses throughout this entire deployment/activation
and disposal procedure.
Wear suitable ear protection when deploying air bag/activating pretensioner. Also, advise those
who are in the area close to deployment/activation site to wear suitable ear protection.
