11A-46 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
The ICU is installed to the steering lock. The ICU
controls the immobilizer system by authentication of the
transponder key and the ECM. An antenna coil is a part
of the ICU and it is located around steering key lock
cylinder. An antenna coil is energized when the ICU is
performing an authentication of the transponder key.
Engine Control Module (ECM)
Legend 1. ECM (4JK1/ 4JJ1)
2. ECM (HFV6)

The ECM is located inside of engine compartment via
mounting bracket and is behind air cleaner case (4JK1/
4JJ1) or attached to the engine (HFV6). The ECM
mainly controls the engine control and also exchanges
a request signal and a response signal to an ICU. If
fault occurs on immobilizer system, the ECM sets
DTC(s) and illuminates the service vehicle soon (SVS)
lamp or the malfunction indicator lamp (MIL). Powertrain Interface Module (PIM)
The PIM is located behind the driver’s side lower hinge
pillar trim. The PIM acts as the communication gateway
between the CAN communication protocol and other
protocol. The PIM converts analog signals from some
switches into serial data. The PIM upon inputs received
from the ECM, TCM and ICU controls the operation of
instruments and indicator lamps. (HFV6)
Transponder Key
Legend 1. Transponder chip

The transponder key accommodates a transponder
chip in the grip portion. The transponder keys have no
conventional power supply. The transponder chip is
energized via a radio wave supplied from an antenna
coil fitted around the steering lock cylinder. Only
transponder key that is correctly programmed key is
possible to engine run. Maximum five transponder keys
can be provided by additional programming.

11B-2 ANTITHEFT SYSTEM

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
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.

General Description
The Antitheft system consists of the four major
components which are Antitheft Control Unit (ACU),
Antitheft horn, key (remote key), and scan tool (Tech-2).
This system can be activated by a correctly
programmed key (remote key) and starter switch is set
to OFF.
This system can be deactivated by a correctly
programmed key (remote key) connected with a
correctly programmed ACU and a correctly
programmed lCU.
W hen the vehicle doors, and engine hood are locked,
the antitheft alarm system is designed to protect your
vehicle and valuables from theft.
Any attempt to forcibly open any door, the engine hood
without using the vehicle key (or remote control) will
cause the hazard lights to flash on and off and the horn
to sound intermittently. This will continue for 30 seconds
(Hazard lamp flash; For 5 minutes) before the system
automatically shuts itself off.
Please operate the door either the key lock or remote
key after closing all doors to arm the alarm system.
Miss waning will be detected when the passenger door
is opened with locked condition and then this door is
closed.

During the first 10 seconds:
• LED lights up; Test, switch - on delay
• LED rapidly flashes (2Hz); Door, bonnet, open or
system fault

After approx. 10 seconds:
• LED slowly flashes; System on (0.5Hz)


RTU7Z0SH019101
Activating the anti-theft system
1. W hen the key switch is turned to the ACC position or
removed from the starter switch.
2. Closing and locking all the doors by the keylock o
r
remote key, and the engine hood will cause the
indicator light to come on.
3. Approximately 10 seconds later, the indicator light will slow flash. The anti-theft system is now in
operation.
Antitheft system alarm operating
conditions
W hen the antitheft system is engaged, the alarm will
operate under the following condition;

1. W henever some forcibly attempts to open a door, the engine hood without using the key.
2. W henever someone unlocks a door with door lock knob.
