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.

Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS6RW0D8204001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified in this manual. Do not use a non-
powered probe type tester.
Instructions in this manual must be followed
carefully, otherwise personal injury may
result.
CAUTION!
• The order in which DTCs are diagnosed is
very important. Failure to diagnose the
DTCs in the order specified may result in
extended diagnostic time, incorrect
diagnosis and incorrect parts replacement.
• When measurement of resistance or
voltage is required in the flow, use a tester
along with a correct terminal adapter from
special tool (Connector test adapter kit).
• When a check for proper connection is
required, refer to “Inspection of
Intermittent and Poor Connections”.
• If an open circuit in the air bag wire
harness damaged, connector or terminal is
found, replace the wire harness,
connectors and terminals as an assembly.
The diagnostic procedures used are designed to find
and repair air bag system malfunctions.
To get the best results, it is important to use the
diagnostic flow and follow the sequence in the following.
1) Perform the “Air Bag Diagnostic System Check
Flow”.
(The “Air Bag Diagnostic System Check Flow” must
be the starting point of any air bag system diagnosis.
The “Air Bag Diagnostic System Check Flow” checks
for proper “AIR BAG” warning light operation through
“AIR BAG” warning light and whether air bag DTCs
exist.)
2) Refer to the proper diagnostic flow as directed by the
“Air Bag Diagnostic System Check Flow”.
(The “Air Bag Diagnostic System Check Flow” will
lead you to the correct flow to diagnose any air bag
system malfunctions. Bypassing these procedures
may result in extended diagnostic time, incorrect
diagnosis and incorrect parts replacement.)
3) Repeat the “Air Bag Diagnostic System Check Flow”
after any repair or diagnostic procedures have been
performed.
(Performing the “Air Bag Diagnostic System Check
Flow” after all repair or diagnostic procedures will
ensure that the repair has been made correctly and
that no other malfunctions exist.)

Connections”.
• If an open circuit in the air bag wire harness damaged, connector or terminal is found, replace the
wire harness, connectors and terminals as an assembly.
