TRANSMITTER
REPLACEMEMT OF THE BATTERY
If the transmitter becomes unreliable, replace the battery.
As the battery power is consumed, the operation distance will be
shorter.
1) Remove screw.
2) Use a small coin or flat blade screwdriver to separate the
bottom half from the top half of the transmitter.
3) Replace the battery with the new one. Make sure the posi-
tive (+) side of battery faces up. For battery replacement,
use type CR2032 or equivalent.
4) Put the two halves back together and install a screw.
5) Make sure the door locks can be operated with the transmit-
ter. Terminal Voltage (V) Condition

INSPECTION
1) Remove mirror switch from instrument panel.
2) Check for continuity between terminals at each switch posi-
tion as show below.
If check result is not as specified, replace mirror switch. CAUTION:
Use care not to allow grease or dirt to be attached on the
printed circuit board and the battery.
NOTE:
To prevent theft, be sure to break the transmitter
before discarding it.
Dispose of the used battery properly according to
applicable rules or regulations. Do not dispose of lith-
ium batteries with ordinary household trash.

HOW TO REGISTER IGNITION KEY ........... 8G-23 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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).

GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.
Engine control module (ECM)
Immobilizer control module (1) with coil antenna
Ignition key (2) with built-in transponder
Operation of this system is as follows.
i) 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.
ii) Immobilizer Control Module compares the Transponder code read in Step (i) and that registered in Immo-
bilizer Control Module and checks if they match.
iii) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Con-
trol Module and ECM check if ECM/Immobilizer Control Module codes registered in them respectively
match.
iv) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (ii) or ECM/Immobilizer Control Module codes in Step (iii) do not match, ECM
will stop operation of the injector and ignition of spark plug.
3. Data link connector (DLC)
4. Immobilizer indicator lamp
5. ECM

8G-20 IMMOBILIZER CONTROL SYSTEM
INSPECTION OF ECM, IMMOBILIZER CON-
TROL MODULE AND ITS CIRCUIT
ECM, Immobilizer Control Module and its circuit can be checked
at ECM wiring couplers and Immobilizer Control Module wiring
coupler by measuring voltage. Described here is only inspection
of Immobilizer Control Module. For inspection of ECM, refer to
“ENGINE & EMISSION CONTROL INPUT/OUTPUT TABLE” in
Section 6E1.
Voltage Check
1) Remove Immobilizer Control Module from steering lock
assembly with ignition switch OFF, referring to “REMOVAL”
of “IMMOBILIZER CONTROL MODULE” in this section.
2) Connect Immobilizer Control Module coupler to Immobilizer
Control Module.
3) Check voltage at each terminal of coupler connected.CAUTION:
Immobilizer Control Module cannot be checked by itself.
It is strictly prohibited to connect voltmeter or ohmmeter
to Immobilizer Control Module with coupler disconnected
from it.
NOTE:
As each terminal voltage is affected by the battery volt-
age, confirm that it is 11V or more when ignition switch is
ON.

8G-22 IMMOBILIZER CONTROL SYSTEM
Do not turn ON ignition switch with a radio antenna placed
near Immobilizer Control Module. Or the system may detect
abnormal condition and prevent engine from starting.
IMMOBILIZER CONTROL MODULE
REMOBAL
1) Disconnect negative (–) cable at battery.
2) Remove steering column upper and lower cover.
3) Disconnect coupler at Immobilizer Control Module.
4) Remove immobilizer control module (1) from steering lock
assembly (2) after removing instrument cluster panel.
INSTALLATION
Reverse removal procedure for installation.
NOTE:
If a screwdriver whose length is 40mm or less is used,
the immobilizer control module can be removed without
removing the instrument cluster panel.
NOTE:
After replacing Immobilizer Control Module, be sure to
register Transponder code and ECM/Immobilizer Control
Module code in Immobilizer Control Module and ECM/
Immobilizer Control Module code in ECM by performing
procedure described in “PROCEDURE AFTER IMMOBI-
LIZER CONTROL MODULE REPLACEMENT” in this sec-
tion.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” 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).
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
specified during reassembly to assure proper retention of these parts.
