1. Ignition key with built-in transponder 1. Data link connector (DLC)
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
Immobilizer Control Module and ECM / Immobilizer Control Module
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.
