5) Using SUZUKI scan tool, register Transponder code in
Immobilizer Control Module by executing “ENT. TRANS
COD (ENT. TP CODE)” command in SELECT MODE menu.
6) Make sure that immobilizer indicator lamp lights when igni-
tion 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).
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”.
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.
4) Using SUZUKI scan tool, register Transponder code in Immobilizer Control Module by executing “ENT.
TRANS COD (ENT. TP CODE)” command in SELECT MODE menu.
5) Using SUZUKI scan tool, register ECM/Immobilizer Control Module code in both Immobilizer Control Module
and ECM by executing “RECORD ECU (RECORD ECM/PCM/ICM)” command in SELECT MODE menu.
6) 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 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 already registered in Immobilizer Control Module.
CAUTION:
When registering the ignition key including a transponder into the immobilizer control module by
using Suzuki scan tool, confirm that the knob color of the ignition key to be registered for the vehicle
is dark gray. The ignition key with wrong knob color cannot be registered.
NOTE:
When “CLR. TRANS COD (CLEAR TP CODE)” command is executed with the immobilizer indicator
lamp 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.

IMMOBILIZER CONTROL SYSTEM 8G-25
PROCEDURE AFTER ECM REPLACEMENT
When ECM was replaced, including when replaced because rechecking by using a known-good ECM was nec-
essary 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”. 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/lCM)” command in SELECT MODE menu.
3) Make sure that malfunction indicator lamp lights when ignition switch is turned OFF once and then ON.
SPECIAL TOOL
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 already registered in Immobilizer Control Module.
NOTE:
For operation procedure of SUZUKI scan tool, refer to SUZUKI scan tool operator’s manual.

AIR BAG SYSTEM 10B-9
AIR BAG DIAGNOSTIC SYSTEM CHECK
The diagnostic procedures used in this section are designed to find and repair air bag system malfunctions.
To get the best results, it is important to use the diagnostic flow tables and follow the sequence listed below.
1) Perform the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE must be the starting point of any air bag sys-
tem diagnosis.
The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE checks for proper “AIR BAG” warning lamp
operation through “AIR BAG” warning lamp and whether air bag diagnostic trouble codes exist.)
2) Refer to the proper diagnostic table as directed by the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW
TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE will lead you to the correct table to diagnose
any air bag system malfunctions. Bypassing these procedures may result in extended diagnostic time, incor-
rect diagnosis and incorrect parts replacement.)
3) Repeat the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after any repair or diagnostic proce-
dures have been performed.
(Performing the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after all repair or diagnostic pro-
cedures will ensure that the repair has been made correctly and that no other malfunctions exist.)
FLOW TABLE TEST DESCRIPTION
STEP 1 : Check that “AIR BAG” warning lamp lights.
STEP 2 : Check that “AIR BAG” warning lamp lights.
STEP 3 : Check diagnosis switch circuit.
STEP 4 : Check that “AIR BAG” warning lamp flashes 6 times after ignition switch is turned ON.
STEP 6 : Check that history codes are in SDM memory. (using SUZUKI scan tool)
STEP 7 : Check that history codes are in SDM memory. (using monitor coupler)
STEP 9 : Check that current code is in SDM memory. (using SUZUKI scan tool)
STEP 10 : Check that current code is in SDM memory. (using monitor coupler)WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equip-
ment other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
CAUTION:
The order in which diagnostic trouble codes are diagnosed is very important. Failure to diagnose the
diagnostic trouble codes in the order specified may result in extended diagnostic time, incorrect diag-
nosis and incorrect parts replacement.
