INSPECTION OF ECM / PCM, IMMOBILIZER
CONTROL MODULE AND ITS CIRCUIT
ECM / PCM, Immobilizer Control Module and its circuit can be
checked at ECM / PCM wiring couplers and Immobilizer Control
Module wiring coupler by measuring voltage and resistance. De-
scribed here is only inspection of Immobilizer Control Module. For
inspection of ECM / PCM, refer to ªSECTION 6E1 or 6E2º.
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.
Voltage Check
1) Remove Immobilizer Control Module from body with ignition
switch OFF, referring to p. 8G-24.
2) Connect Immobilizer Control Module coupler to Immobilizer
Control Module.
3) Check voltage at each terminal of coupler connected.
NOTE:
As each terminal voltage is affected by the battery voltage,
confirm that it is 11 V or more when ignition switch is ON.

Resistance Check
1) Disconnect Immobilizer Control Module couplers from Immobi-
lizer Control Module with ignition switch OFF.
CAUTION:
Never touch terminals of Immobilizer Control Module it-
self or connect voltmeter or ohmmeter.
2) Check resistance between each terminal of coupler discon-
nected.
CAUTION:

Be sure to connect ohmmeter probe from wire harness
side of coupler.

Be sure to turn OFF ignition switch for this check.

PRECAUTIONS IN HANDLING IMMOBILIZER
CONTROL SYSTEM

Do not turn ON ignition switch with ignition key for immobilizer
control system put together with another one or placed quite close
to another one. Or the system may detect abnormal condition and
prevent engine from starting.

Do not turn ON ignition switch by using ignition key with any type
of metal wound around its grip or in contact with it. Or the system
may detect abnormal condition and prevent engine from starting.

Do not leave ignition key where high temperature is anticipated.
High temperature will cause transponder in ignition key to be ab-
normal or damaged.

Do not turn ON ignition switch with a radio antenna placed near
coil antenna or its harness to Immobilizer Control Module. Or the
system may detect abnormal condition and prevent engine from
starting.

HOW TO REGISTER IGNITION KEY
Register the ignition key with a built-in transponder in Immobilizer
Control Module by using the following procedure.
1) Prepare Suzuki scan tool (TECH 1A kit and cartridge for immobi-
lizer control system).
2) With ignition switch OFF, connect Suzuki scan tool to data link
connector (DLC) located on underside of instrument panel at
driver's seat side.
Special Tool
(A): 09931-76011 (Tech 1A)
(B): Immobilizer cartridge
(C): 09931-76030 (16 / 14-pin DLC cable)
NOTE:
For operation procedure of Suzuki scan tool, refer to Suzuki
scan tool operator's manual.
3) Prepare ignition key with a built-in transponder. And then turn
ignition switch ON by using it.
4) Number of Transponder codes for ignition key with a built-in
transponder that can be registered in Immobilizer Control Mod-
ule is limited to 4. If needed, clear all Transponder codes for igni-
tion key with a built-in transponder that have been registered in
Immobilizer Control Module by executing the ªCLR. TRANS
COD (CLEAR TP CODE)º command in the SELECT MODE
menu by using Suzuki scan tool.
NOTE:
When ªCLR. TRANS COD (CLEAR TP CODE)º command is
executed with the malfunction indicator lamp (the lamp for
vehicles equipped with the monitor coupler) ON or the im-
mobilizer indicator lamp (the lamp for vehicle not equipped
with the monitor coupler) ON, it remains ON even after
execution of that command is over. It will start flashing
when the ignition switch is turned OFF once and then
turned ON after some seconds.
5) Using Suzuki scan tool, register Transponder code in Immobiliz-
er Control Module by executing ªENT. TRANS COD (ENT. TP
CODE)º command in SELECT MODE menu.
6) [Vehicle equipped with monitor coupler]
Make sure that malfunction indicator lamp lights when ignition
switch is turned OFF once and then ON.
[Vehicle not equipped with monitor coupler]
Make sure that immobilizer indicator lamp lights when ignition
switch is turned OFF once and then ON.

7) If any other Transponder code for ignition key with a built-in
transponder needs to be registered, repeat above Steps 3), 5)
and 6).
NOTE:

Up to 4 Transponder codes for ignition key with a built-in
transponder can be registered.

It is not possible to register the same Transponder code
for ignition key with a built-in transponder as the one al-
ready registered in Immobilizer Control Module.
PROCEDURE AFTER IMMOBILIZER
CONTROL MODULE REPLACEMENT
When Immobilizer Control Module was replaced, including when
replaced because rechecking by using a known-good Immobilizer
Control Module was necessary during trouble diagnosis, register
Transponder code and ECM / Immobilizer Control Module code in

code in ECM/PCM by performing following procedure.
1) Perform Steps 1) and 2) described in ªHow to register ignition
keyº section.
2) Prepare ignition key with a built-in transponder. And then turn
ignition switch ON by using it.
3) Using Suzuki scan tool, clear all transponder codes registered
in Immobilizer Control Module by executing ªCLR. TRANS COD
(CLEAR TP CODE)º command in SELECT MODE menu.
NOTE:
When ªCLR. TRANS COD (CLEAR TP CODE)º command is
executed with the malfunction indicator lamp (the lamp for
vehicles equipped with the monitor coupler) ON or the im-
mobilizer indicator lamp (the lamp for vehicles not
equipped with the monitor coupler) ON, it remains ON even
after execution of that command is over. It will start flashing
when the ignition switch is turned OFF once and then
turned ON after some seconds.
4) Using Suzuki scan tool, register Transponder code in Immobiliz-
er Control Module by executing ªENT. TRANS COD (ENT. TP
CODE)º command in SELECT MODE menu.
5) Using Suzuki scan tool, register ECM / Immobilizer Control Mod-
ule code in both Immobilizer Control Module and ECM / PCM by
executing ªRECORD ECU (RECORD ECM / PCM / ICM)º com-
mand in SELECT MODE menu.
6) [Vehicle equipped with monitor coupler]
Make sure that malfunction indicator lamp lights when ignition
switch is turned OFF once and then ON.
[Vehicle not equipped with monitor coupler]
Make sure that immobilizer indicator lamp lights when ignition
switch is turned OFF once and then ON.
7) If any other Transponder code for ignition key with a built-in trans-
ponder needs to be registered, repeat above Steps 2), 4) and 6).
NOTE:

Up to 4 Transponder codes for ignition key with a built-in
transponder can be registered.

It is not possible to register the same Transponder code
for ignition key with a built-in transponder as the one al-
ready registered in Immobilizer Control Module.

SECTION 9
BODY SERVICE
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).

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.
