Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fasteners joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fasteners.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.

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.

Service Precautions
WARNING: S A F E T Y P R ECAUTIONS MUST BE
FOLLOWED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE AIR
BAG ASSEMBLY SURFACE MAY CONTAIN A SMALL
AMOUNT OF SODIUM HYDROXIDE, A BY±PRODUCT
OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO THE SKIN AND EYES. MOST OF THE
POWDER ON THE AIR BAG ASSEMBLY IS
HARMLESS. AS A PRECAUTION, WEAR GLOVES
AND SAFETY GLASSES WHEN HANDLING A
DEPLOYED AIR BAG ASSEMBLY, AND WASH YOUR
HANDS WITH MILD SOAP AND WATER
AFTERWARDS.
WARNING: W H E N C A R RY I N G A L I V E A I R B A G
ASSEMBLY, MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU. NEVER
CARRY AIR BAG ASSEMBLY BY THE WIRES OR
CONNECTOR ON THE UNDERSIDE OF MODULE. IN
THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE
BAG WILL THEN DEPLOY WITH MINIMAL CHANCE
OF INJURY. WHEN PLACING A LIVE AIR BAG
ASSEMBLY ON A BENCH OR OTHER SURFACE,
ALWAYS FACE BAG AND TRIM COVER UP, AWAY
FROM THE SURFACE. NEVER REST A STEERING
COLUMN ASSEMBLY ON THE STEERING WHEELWITH THE AIR BAG ASSEMBLY FACE DOWN AND
COLUMN VERTICAL. THIS IS NECESSARY SO THAT
A FREE SPACE IS PROVIDED TO ALLOW THE AIR
BAG ASSEMBLY TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE: In the event deployment has occurred, inspect
coil assembly wire for any signs of scorching, melting or
any other damage due to excessive heat. If the coil has
been damaged, replace it.
Removal
1. Disable the SRS. (Refer to ªDisabling the SRSº in this
section.)
2. Remove the air bag assembly (5) from steering wheel
(6) by removing two bolts (7). Lift air bag assembly out
of steering wheel.
3. Disconnect connector (2) and remove air bag
assembly.
4. Disconnect horn lead (1)
5. Remove steering wheel attachment nut (4).

SUPPLEMENTAL RESTRAINT SYSTEM9J±31
6. Move the tires to the straight ahead position before
removing the steering wheel. Install steering wheel
puller onto steering wheel and remove steering wheel
with J±29752.
7. Apply a setting mark (3) across the steering wheel
and shaft so parts can be reassembled in their
original position.
8. Feed wiring through the wheel and remove wheel.
CAUTION: Never apply force to the steering wheel
in direction of the shaft by using a hammer or other
impact tools in an attempt to remove the steering
wheel. The steering shaft is designed as an energy
absorbing unit.
