8H–22SECURITY AND LOCKS
Anti-theft System
General Description
The circuit consists of the starter switch, anti-theft &
keyless entry control unit, anti-theft horn, front door and
tailgate key switch (detect and tamper switch), door lock
(& power window) 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 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 “OFF” to “ACC” 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 Precaution
WARNING: IF SO EQUIPPED WITH 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
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.

SUPPLEMENTAL RESTRAINT SYSTEM9J–37
Steering Wheel
Service Precautions
WARNING: SAFETY PRECAUTIONS 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
POWER 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: WHEN CARRYING A LIVE AIR BAG
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 ALIVE AIR BAG
ASSEMBLY ON A BENCH OR OTHER SURFACE,
ALWAYS FACE BAG AND RIM COVER UP, AWAY
FROM THE SURFACE. NEVER REST A STEERING
COLUMN ASSEMBLY ON THE STEERING WHEEL
WITH 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 “Disabling the SRS” in this
section).
2. Loosen the air bag assembly fixing bolts from behind
the steering wheel assembly using a TORX
d r i v e r o r
equivalent until the air bag assembly can be released
from steering wheel.
827RT008
3. Disconnect the yellow 2–pin connector located
behind the air bag assembly and remove air bag
assembly.Refer to “SRS Connectors” in this section
for removal and installation.
4. Disconnect horn lead.

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.
Installation
1. Install the steering wheel and align the setting marks.

2. Tighten the steering wheel fixing nut to the specified
torque.
Torque : 34 Nꞏm (3.5 Kgꞏm/25 Ib ft)
3. Connect horn lead.
4. Connect air bag to wiring harness connector.
NOTE: Pass the lead wire through the tabs on the plastic
cover (wire protector) of air bag to prevent lead wire from
being pinched.

13. Disconnect the 12–pin wiring harness connectors
located at the base of steering column.
CAUTION: Never apply force to the steering wheel
in the 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.
14. Remove the combination switch assembly with SRS
coil.

SUPPLEMENTAL RESTRAINT SYSTEM9J–41
Installation
1. Install the combination switch assembly with SRS
coil.
2. Turn the SRS coil counterclockwise to full, return
about 3 turns and align the neutral mark (1).
CAUTION: W h e n t u r n i n g t h e S R S c o i l
