Anti-Theft System
General Description
The circuit consists of the starter switch, anti±theft &
keyless entry controller, anti±theft horn, front door and
tailgate key switch (detect and tamper) switch, door lock
actuator for each door, engine hood switch, clutch start
switch (M/T), ANTI±THEFT indicator light and mode
switch (A/T).
The system operates as follows: After locking the starter
switch and removing the starter key (this sets the alarm),
if the door is unlocked in any way other than with the
proper key, the headlights will start flashing, the horn
sounds, and the starter circuit is disabled. (However, the
engine hood and all the doors must be locked and closed.)
Once the system has been placed in the warning or alarm
condition, it can be released only when the starter switch
is shifted from ªOFFº to ªACCº by the starter key, or when
the lock of the front door or the tailgate is released (to
activate the detect switch) by the starter key.

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.

SUPPLEMENTAL RESTRAINT SYSTEM 9J±10
The air bag assembly has identification colors on the
bar code label as follows.
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.
Turn ignition switch to ªLOCKº and remove key.
1. Connect yellow 2±pin connector passenger air bag
assembly.
2. Install glove box assembly, refer to ªPassenger Air
Bag Assembly Replacementº in section 9J±28.
3. Connect yellow 2±pin connector at the base of
steering column.
4. Install ªAIR BAGº fuse SRS±1 to left dash side lower
fuse block or connect battery.
Turn ignition switch to ªONº and verify that the ªAIR BAGº
warning lamp flashes seven times and then turns ªOFFº If
it does not operate as described, perform the ªSRS
Diagnostic System Checkº in section 9J1±3.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200
F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet).
3. When a SDM is replaced, it must be oriented with the
arrow on the sensor pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as this
will set a diagnostic trouble code.
5. The ªSRS Diagnostic System Checkº must be the
starting point of any SRS diagnostics. The ªSRS
Diagnostic System Checkº will verify proper ªAIR
BAGº warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacement.
Air Bag Assembly Handling /
Shipping / Scrapping
Live (Undeployed) Air Bag Assembly
Special care is necessary when handling and storing a
live (undeployed) air bag assembly. The rapid gas
generation produced during deployment of the air bag
could cause the air bag assembly, or an object in front of
the air bag assembly, to be thrown through the air in the
unlikely event of an accidental deployment.
