Precautions
Precautions on Service and Diagnosis of Air
Bag System
S7RS0B8200001
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/BAG” fuse and air bag (inflator) module(s) (driver,
passenger, side of both si des and curtain of both
sides) 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 S ystem Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning right operatio n 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, passenger, side of both si des and curtain of both
sides), seat belt pretensio ners (driver and passenger),
SDM, forward-sensor or side-sensor, be careful not to
drop it or apply an impact to it. If an excessive impact
was applied (e.g., SDM, forward-sensor and side-
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, passenger,
side of both sides and curtain of both sides) 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 expo sed 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.

Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS7RS0B8204001
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.
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 right operation
through “AIR BAG” warning right and whether air
bag DTCs exist.)
2) Refer to the proper diagnost ic 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.)

DTC CheckS7RS0B8204004
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
If communication between scan tool and SDM is not
possible, check if scan tool is communicable by
connecting it to SDM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. 5) After completing the check,
turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).

CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this 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 there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
Flow Test Description
Step 1: Check for “A/BAG” fuse blown.
Step 2, 3: Check for loose connection between junction block assembly connector and junction block
assembly.
Step 4: Check for loose connection between SDM connector and SDM.
Step 5: Check for SDM power supply circuit.
Step 6: Check for short circuit between “A IR BAG” warning right circuit and ground.
Troubleshooting Step Action YesNo
1 1) Turn ignition switch OFF.
2) Remove and inspect “A/BAG” fuse.
Is fuse good? Go to Step 2.
“RED” wire short to
ground.
After repair, replace “A/
BAG” fuse.
2 1) Check for loose connection of junction block assembly connector “L04”.
Is it connected securely? Go to Step 3.
Correct connector “L04”
securely.
3 1) Check for loose connection of junction block assembly connector “G34”.
Is it connected securely? Go to Step 4.
Correct connector “G34”
securely.
4 1) Check for loose connection of SDM connector “L29”. Is it connected securely? Go to Step 5.
Correct connector “L29”
securely.
5 1) Disconnect SDM connector “L29”. 2) Check proper connection to SDM at terminal “L29-27”.
3) If OK, then check voltage between “L29-27” terminal of SDM connector and body ground with ignition switch
ON.

Is it 8 V or more? Go to Step 6.
“RED” wire (between “A/
BAG” fuse and SDM
connector) open or
“GRN” wire (between
ignition switch and “A/
BAG” fuse) open or
short to ground.

NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.
“AIR BAG” Warning Right Does Not Come ONS7RS0B8204008
Wiring Diagram6 1) Disconnect combination meter connector “G28” referring
to “Combination Meter Removal and Installation in
Section 9C”.
2) Check proper connection to combination meter at “YEL/ BLK” terminal for “AIR BAG” warning right and to SDM at
terminal “L29-2”.
3) If OK, then check resistance between “YEL/BLK” wire terminal of combination meter connector “G28” and
“L29-2” terminal of SDM connector.
Special tool
(A): 09932-76010
Is resistance 1
Ω or less? Substitute a known-
good SDM and recheck.
If “AIR BAG” warning
right remain lighting,
replace combination
meter.
“YEL/BLK” wire
(between combination
meter and SDM
connector) open or
short to ground.
