Precautions
Precautions on Service and Diagnosis of Air
Bag System
S6RW0D8200004
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, both front seat or any other on
or around air bag system components.
Modifications can adversely affect air bag
system performance and lead to injury.
• Be sure to follow the procedures described
in this section. Failure to follow
procedures could result in possible air bag
system activation, personal injury or
unneeded air bag system repairs.

• 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
“A/B” fuse and air bag (inflator) module(s) (driver
module, passenger module, side modules and curtain
modules) 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 flow
requests it, as this will set a 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 light operation and will lead you to the
correct flow 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
process), remove the air bag system components
beforehand to avoid component damage or
unintended system activation.• When handling the air bag (inflator) modules (driver
module, passenger module, side modules and curtain
modules), seat belt pretensioners (driver module and
passenger module), SDM, forward impact-sensor or
side impact-sensor be careful not to drop it or apply
an impact to it. If an excessive impact was applied
(e.g., SDM, forward impact-sensor are 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 disassembly or repair but
replace it with a new one.
• When using electric welding, be sure to disconnect air
bag (inflator) module connectors (driver module,
passenger module, side modules and curtain
modules) and seat belt pretensioner connectors
(driver module and passenger module) 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 procedures listed in “Disabling Air
Bag System” 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.

Precautions on Handling and Storage of Air Bag
System Components
S6RW0D8200002
SDM
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, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.

• 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
(inactivated) 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 immediately 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!
• For handling and storage of a live seat belt
pretensioner, 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
webbing.
• When placing a live seat belt pretensioner
on the workbench 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.

Deployed Air Bag (Inflator) Module and Activated
Seat Belt Pretensioner
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
proceeding the work.
• Do not apply water, oil, etc. to deployed air
bag (inflator) 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 residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products 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 completing the work.

Refer to the procedure described under “Deployed Air
Bag (Inflator) Module and Activated Seat Belt
Pretensioner Disposal” for disposal.
Air Bag Wire Harness and Connector
Air bag wire harness is included in main harness (1),
instrument panel harness (4), floor harness (3), seat
harness (5) and curtain air bag harness (6). Air bag wire
harness can be identified easily as the part of connector
side wire harness is covered with a yellow protection
tube. Be very careful when handling it.
• When an open in air bag wire harness, damaged wire
harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• When installing it, be careful so that the air bag wire
harness is not caught or does not interfere with other
parts.
• Make sure air bag system grounding point (2) is clean
and ground is securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.
