CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
Step Action Yes No
1 1) Make sure that SUZUKI scan tool is free from malfunc-
tion and correct cartridge for air bag system is used.
2) Ignition switch OFF.
3) Check proper connection of SUZUKI scan tool to DLC.
Is connection in good condition?Go to step 2. Properly connect SUZUKI
scan tool to DLC.

HANDLING AND STORAGE
SDM
Never attempt disassembly of SDM.
When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
If SDM has been dropped, replace it with a new one.
If installation part of SDM was damaged, repair that part
completely before reinstallation.
All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
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, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.

AIR BAG SYSTEM 10B-57
INSPECTION
Check SDM (3) and SDM plate (5) for dents, cracks or defor-
mation.
Check SDM connector (2) for damage, cracks or lock mech-
anism.
Check SDM terminal for bent, corrosion or rust.
If any faulty condition is found in above checks, replace.
INSTALLATION
For installation, reverse removal procedure, nothing following
points.
Ensure that arrow (4) on the SDM (3) is pointing toward the
front of the vehicle.
Tighten SDM bolts to specified torque.
Tightening torque
SDM mounting bolt (a) : 6 N·m (0.6 kg-m, 4.5 lb-ft)
Connect SDM connector (2) to SDM (3) securely.
Enable air bag system. Refer to “ENABLING AIR BAG SYS-
TEM”. CAUTION:
Do not connect a tester whatever type it may be.
Never repair or disassemble SDM (3).
If SDM has been dropped, or if there are cracks, dents
or other defects in the case or plate, replace it with a
new one.

DEPLOYMENT/ACTIVATION OUTSIDE VEHI-
CLE
Use this procedure when the vehicle itself is used again (only the
air bag (inflator) module(s) and seat belt pretensioner(s) are dis-
posed).
1) Turn ignition switch to “LOCK”, position remove key and put
on safety glasses.
2) Check that there is no open, short or damage in special tool
(deployment harness). If any faulty is found, do not use it
and be sure to use new deployment harness.
Special tool
(A) : 09932-75030
3) Short (1) the two deployment harness leads together by fully
seating one banana plug into the other.
4) Remove air bag (inflator) module(s) and seat belt preten-
sioner(s) from vehicle, referring to SECTION 3C, 10B and
10. WARNING:
Deployment harness shall remain shorted and not be
connected to a power source until the air bag is to be
deployed and seat belt pretensioner is to be activated.
WARNING:
Always carry live air bag (inflator) module with trim
cover away from you.
When storing a live air bag (inflator) module or when
leaving a live air bag (inflator) module unattended on a
bench or other surface, always face the bag and trim
cover up and away from the surface. As the live pas-
senger 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).
This is necessary so that a free space is provided to
allow the air bag to expand in the unlikely event of
accidental deployment.
Failure to follow procedures may result in personal
injury.

6) Stretch the deployment harness from the driver or passen-
ger air bag (inflator) module to its full length 10 m (33 ft) (1).
Special tool
(A) : 09932-75030
7) Place a power source (3) near the shorted end of the deploy-
ment harness. Recommended application: 12 Volts mini-
mum, 2 amps minimum. A vehicle battery is suggested.
8) Verify that the area around the air bag (inflator) module or
seat belt pretensioner is clear of all people and loose or flam-
mable objects.
9) Verify setting condition of air bag (inflator) module or preten-
sioner as follows.
[In case of driver air bag (inflater) module]
Verify that the driver air bag (inflator) module is resting with
its vinyl trim cover facing up.
[In case of passenger air bag (inflator) module]
Verify that the passenger air bag (inflator) module is firmly
and properly secured in passenger air bag (inflator) module
deployment fixture (special tool).
[In case of seat belt pretensioner]
Verify that the seat belt pretensioner, is placed as shown in
the figure on the ground in the space just cleared.
10) Connect (2) the air bag (inflator) module or seat belt preten-
sioner to the deployment harness connector and lock con-
nector with lock lever.
11) Notify all people in the immediate area that you intend to
deploy/activate the air bag (inflator) module or seat belt pre-
tensioner.
NOTE:
When the air bag deploys and the pretensioner acti-
vates, the rapid gas expansion will create a substantial
report. Wear suitable ear protection. Notify all people
in the immediate area that you intend to deploy the air
bag (inflator) module or activate the seat belt preten-
sioner and suitable ear protection should be worn.
When the driver air bag deploys and the pretensioner
activates, driver air bag (inflator) module and preten-
sioner (retractor assembly) may jump about 30 cm (1
ft) vertically. This is a normal reaction of them to the
force of the rapid gas expansion inside the air bag and
pretensioner.
After the 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.

AIR BAG SYSTEM 10B-67
DEPLOYMENT/ACTIVATION INSIDE VEHICLE
Use this procedure when scrapping the entire vehicle including
the air bag (inflator) modules and seat belt pretensioners.
1) Turn ignition switch to “LOCK” position, remove key and put
on safety glasses.
2) Remove all loose objects from front seats and instrument
panel.
3) [For driver air bag (inflator) module]
Disconnect contact coil connector (1) located near the base
of the steering column.
[For passenger air bag (inflator) module]
Remove glove box from instrument panel and disconnect
passenger air bag (inflator) module connector (2).
[For seat belt pretensioner]
Remove both side (driver and passenger side) center pillar
lower trim and disconnect seat belt pretensioner connectors
(3).
4) Confirm that each air bag (inflator) module is securely
mounted.
5) Check that there is no open, short or damage in special tool
(deployment harness). If any faulty condition is found, do not
use it and be sure to use new deployment harness.
Special tool
(A) : 09932-75030
6) Short (1) the two deployment harness leads together by fully
seating one banana plug into the other.
7) Connect deployment harness connector to air bag (inflator)
module (driver or passenger) or seat belt pretensioner
(driver or passenger) and lock connector with lock lever.
a) Connect connector.
b) Lock connector with lock lever.CAUTION:
When vehicle itself will be used again, deploy/activate
the air bag and pretensioner outside vehicle according to
“DEPLOYMENT/ACTIVATION OUTSIDE VEHICLE”, for
deploying/activating it inside will cause the instrument
panel, glove box and their vicinity to be deformed.
Failure to observe this CAUTION may require unneeded
vehicle inspection and repair.
