11) Turn ignition switch ON.
Do other indicator / warning lights in
combination meter come ON?Go to Step 2.“IG” fuse blown, main fuse blown,
ignition switch malfunction,
“(d)” circuit between “IG” fuse
and combination meter or poor
coupler connection at
combination meter.
21) Turn ignition switch OFF and
disconnect connectors from ECM.
2) Check for proper connection to ECM
at terminal C02-18 for G10 engine or
C01-28 for G13B engine.
3) If OK, then using service wire, ground
terminal C02-18 for G10 engine or
C01-28 for G13B engine in connector
disconnected.

good ECM and
recheck.Bulb burned out or “(P)” wire

IMMOBILIZER CONTROL SYSTEM 8G-17
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 by performing following procedure.
1) Perform Steps 1) and 2) described in “How to register ignition
key” 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 “CLR. TRANS COD
(CLEAR TP CODE)” command in SELECT MODE menu.
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.
4) 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.
5) Using Suzuki scan tool, register ECM / Immobilizer Control Mod-
ule code in both Immobilizer Control Module and ECM by
executing “RECORD ECU (RECORD ECM / PCM / ICM)” 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.

PROCEDURE AFTER ECM
REPLACEMENT
When ECM was replaced, including when replaced because re-
checking by using a known-good ECM was necessary during
trouble diagnosis, register ECM/Immobilizer Control Module code
in ECM by performing following procedure.
1) Perform Steps 1) and 2) described in “How to register ignition
key” section. And then turn ignition switch ON.
2) Using Suzuki scan tool, register ECM/Immobilizer Control Module
code in ECM by executing “RECORD ECU (RECORD ECM / Im-
mobilizer Control Module)” command in SELECT MODE menu.
NOTE:
For operation procedure of Suzuki scan tool, refer to Suzuki
scan tool operator’s manual.
3) [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.
