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.

for which these three modes, ID code new registration, ID
code additional registration and ID code check, are
available.
ID Code New Registration

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.
