WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

8G-2 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.

Engine control module (ECM) / Powertrain control module (PCM)

Immobilizer control module

Ignition key (with built-in transponder)

Coil antenna
Operation of this system is as follows.
(1) Each ignition key has its own code (Transponder code) stored in memory. When the ignition switch is turned
ON, Immobilizer Control Module tries to read the Transponder code through the coil antenna installed to the
steering lock assembly.
(2) Immobilizer Control Module compares the Transponder code read in (1) and that registered in Immobilizer Con-
trol Module and checks if they match.
(3) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Control
Module and ECM / PCM check if ECM/Immobilizer Control Module codes registered in them respectively match.
(4) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (2) or ECM/Immobilizer Control Module codes in Step (3) do not match, ECM / PCM
will stop operation of the injector and ignition of spark plug.

IGNITION KEY
The ignition key for the immobilizer control system has a built-in
transponder. Each transponder in the key has an each transmitting
code (Transponder code). The code will transmitted from the key
via the coil antenna to Immobilizer Control Module when the ignition
switch is turned ON.
COIL ANTENNA
The coil antenna is installed to the steering lock assembly. As it is
energized by Immobilizer Control Module, it transmits the trans-
ponder code of the ignition key to Immobilizer Control Module.

When body servicing, if shock may be applied to air bag system component parts, remove those parts
beforehand. (Refer to Section 10B.)
NOTE:
Fasteners are important attaching parts in that they could affect the performance of vital components and
systems, and / or could result in major repair expense. They must be replaced with one of the same part
number of with an equivalent part if replacement becomes necessary.
Do not use a replacement part of lesser quality or substitute a design. Torque values must be used as spe-
cified during reassembly to assure proper retention of these parts.

WARNING:
Handling of Back Door / Rear Gate Balancer (Damper)

Do not disassemble balancer because its cylinder is
filled with gas.

The gas itself is harmless but it may issue out of the
hole together with chips generated by the drill.
Therefore, be sure to wear goggle.

When discarding removed back door / rear gate balanc-
er (damper), use a 2 to 3 mm (0.08 to 0.12 in.) drill to
make a hole as shown.

Handle balancer carefully. Do not scar or scratch ex-
posed surface of its piston rod, and never allow any
paint or oil to stick to its surface.

Do not turn piston rod with balancer fully extended.
5) Remove back door / rear gate hinge bolts and back door / rear
