Light blue color for driver air bag assembly.
Light blue color for passenger air bag assembly.
Use only the air bag assembly for AXIOM (UP) mod-
els.
CAUTION: Proper operation of the sensors and
Supplemental Restraint System (SRS) requires that
any repairs to the vehicle structure return it to the
original production configuration. Deployment
requires, at a minimum, replacement of the SDM, air
bag assembly and dimensional inspection of the
steering column. Any visible damage to the SDM
mounting bracket (s) requires replacement, and the
steering column must be dimensionally inspected,
whether deployment occurred or not.
Accident With Deployment ± Component
Replacement and Inspections
Certain SRS components must be replaced or inspected
for damage after a frontal crash involving air bag
deployment. Those components are:

Air bag assembly

SDM
CAUTION: Refer to ªSDM Replacement Guidelinesº
below for important information on SDM
replacement in both deployment and non
deployment crashes.

SRS coil assemblyÐInspect wiring and connector for
any signs of scorching, melting, or damage due to
excessive heat. Replace if damaged. Refer to SRS
coil assembly in this section.
Accident With or Without
DeploymentÐComponent Inspection
Certain SRS and restraint system components must be
inspected after any crash, whether the air bag deployed
or not. Those components are:

Steering columnÐDimensionally inspect per
ªChecking Steering Column for Accident Damageº in
3 of this workshop manual.

Knee bolsters and mounting pointsÐ Inspect for any
distortion, bending, cracking, or other damage.

I/P steering column reinforcement plateÐ Inspect for
any distortion, bending, cracking, or other damage.

I/P bracesÐInspect for any distortion, bending,
cracking, or other damage.

Seat belts and mounting pointsÐRefer to ªSeat
Beltsº in 10 of this workshop manual.
SDM Replacement Guidelines
SDM replacement policy requires replacement of SDM,
after crash involving air bag deployment when ªSRS
Warning Lampº turn ªONº, ªSRS Diagnosisº should be
done according to ªSection 9J1º.
Wiring Damage
If any SRS wire harness is damaged, it should be
replaced. Don't repair SRS. It is replace only.
SRS Connector (Plastic Body And
Terminal Metal Pin) Damage
If any connector or terminal in the SRS wire harness
(except pigtails) is damaged, it should be replaced.
SRS Wire Pigtail Damage
If the wiring pigtail (a wire or wires attached directly to the
device, not by a connector) is damaged, the entire
component (with pigtail) must be replaced. Examples of
ªpigtailº components are the driver air bag assembly, the
passenger air bag assembly, and the SRS coil assembly.
On±Vehicle Service
Service Precautions
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in DriverÐPassenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned ªOFFº, the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
ªSRS±1º fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the ªDisabling the SRSº
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to ªlockº and remove key.
1. Remove SRS fuse SRS±1, from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2±pin connector at the base of
steering column.
3. Remove glove box assembly, Refer to ªPassenger Air
Bag Assembly Replacementº in section 9J±28.
4. Disconnect yellow 2±pin connector behind the glove
box assembly.
CAUTION: With the ªSRS±1º fuse removed and
ignition switch ªONº, ªAIR BAGº warning lamp will
be ªONº. This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
CAUTION: Never use the air bag assembly from
another vehicle and difference model year air bag
assembly.

RESTRAINT CONTROL SYSTEM
ªFlash Codeº Diagnostics
Flash code diagnostics can be used to read current codes
and to determine if history codes are present but cannot
be used to clear codes or read history codes. Flash code
diagnostics is enabled by grounding by terminal 13
shorting to terminal 4 of the DLC with the ignition switch
ªONº. Grounding terminal 13 of the DLC pulls the
ªDiagnostics Requestº input (Terminal 1) of the SDM low
and signals the SDM to enter the flash code diagnostic
display mode.
The SDM displays the trouble codes by flashing the
warning lamp. Each code that is displayed will consist of a
number of flashes which represents the tens digit, a 1.2
second pause, following by a number of flashes which
represents the ones digit of the code. Each code isdisplayed one time before moving on to the next code.
After all of the codes have been displayed, the entire code
sequence will continually by repeated until ground is
removed from terminal 13 of the DLC.
Two special codes exist when reading in the flash code
mode (Flash Code 12 and Flash Code 13). ªFlash Code
12º will always be the first code displayed when the flash
code mode is enabled Code 12 is not an indication of a
SRS problem but an indication that the flash code mode
has been enabled. If there are no current or history codes
present, the SDM will display code 12 until ground is
removed from the DLC at terminal 13. ªFlash Code 13º
will be displayed if there are history codes. To read the
history codes, a scan tool must be used.
