Special Tool
(A): 09931-76011 (Suzuki scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 14 pin DLC adapter)
3) Turn ignition switch ON.
4) Read DTC stored in ECM according to instructions displayed on
Suzuki scan tool and print it or write it down. Refer to Suzuki scan
tool operator’s manual for further details.
NOTE:
When reading DTC stored in ECM using Suzuki scan tool,
select “ECM” from the applications menu and “SUZUKI
mode” from the communication mode menu displayed on
Suzuki scan tool.
If ECM detects a trouble in both electric fuel injection sys-
tem and immobilizer control system, Suzuki scan tool in-
dicates trouble codes of both systems using Suzuki mode
of ECM application.
If communication between Suzuki scan tool and ECM is not pos-
sible, check if Suzuki scan tool is communicable by connecting
it to ECM in another vehicle. If communication is possible in this
case, Suzuki scan tool is in good condition. Then check data link
connector and serial data line (circuit) in the vehicle with which
communication was not possible.
5) After completing the check, turn ignition switch OFF and discon-
nect Suzuki scan tool from 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 “CLR. TRANS
COD (CLEAR TP CODE)” command in the SELECT MODE
menu by using Suzuki scan tool.
NOTE:
When “CLR. TRANS COD (CLEAR TP CODE)” 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 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 “ENT. TRANS COD (ENT. TP
CODE)” 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.
