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.
3. W henever the engine hood release handle is operated.

ANTITHEFT SYSTEM 11B-3
Function of a keyless entry system
W ith a keyless entry system the car can be locked or
unlocked from any position around the car up to a
specified distance, by using the potable radio remote
transmitter inside key (remote key).
Status LED
W hile the system is in delay the alarm system is active
and LED flashes at 0.5Hz with or without activated
interior protection.
Hazard relay
The hazard warning lights will be activated by an
external relay. The output is low active.
Switches
All switches to ground. This makes it possible for failure
analysis to detect a short circuit or a broken wire to
each switch. To use this feature it is necessary to place
a 1.8k Ω resistor in parallel to the required switch.
Receiver
The receiver is integrated into the control unit.
To lower the idle current the receiver is equipped with a
standby mode. The antenna is integrated on the printed
circuit board.
Depending on the mounting position of the control unit
the antenna can be connected externally.
Range of communication
The range of communication between remote key and
receiver is intended to be least 3 m from centre of the
car.


Diagnosis
For diagnostic purpose the communication with an
internal diagnostic device ( Tech-2 ) is possible.

901RW 176
Transmitter (into remote key)
• Electronics integrated in remote key container for
TFR/TFS.
• Antenna integrated in remote key container.
• Frequency band is 433.92 MHz.
• Two function buttons (Door lock/Door unlock)
• Two status LED for TF (Door lock/Door unlock)
