Diagnostic Information and Procedures

Immobilizer Control System Check

S6JB0AA324001

Diagnostic Trouble Code (DTC) Check

S6JB0AA324002

NOTE
To know how to use SUZUKI scan tool in
detail, refer to its operator’s manual.

1) Turn the ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector

(DLC) (1) located under instrument panel at driver’s
seat side.

Special tool
(A): SUZUKI scan tool

3) Turn the ignition switch to ON position.
4) Check if any DTC is stored in ICM according to the

instructions displayed on SUZUKI scan tool.

5) After completing the check, turn ignition switch to

OFF position, and then disconnect SUZUKI scan
tool from DLC.

Step

Action

Yes

No

1

Injection warning light ON check
1) Turn ignition switch to ON position using ignition key.

Does injection warning light (1) come on?

Go to Step 2.

Go to “Injection Warning
Light Does Not Come
ON with Ignition Switch
ON and Engine Stop:
For Diesel Engine
Model”.

2

Injection warning light flash check

Does injection warning light flash on and off continuously in
Step 1?

Check ICM for DTC
referring to “Diagnostic
Trouble Code (DTC)
Check: For Diesel
Engine Model”.

Go to Step 3.

3

Engine start check
1) Start engine using ignition key.

Does engine start?

Go to step 4.

Go to “Engine and
Emission Control
System Check: For
Diesel Engine Model in
Section 1A”.

4

Injection warning light remain ON check
1) Check if injection warning light remains ON after engine

start.

Does injection warning light remain ON after engine start?

Go to “Injection Warning
Light Remains ON after
Engine Start: For Diesel
Engine Model”.

Immobilizer control
system is in good
condition.

Immobilizer control module (ICM)

NOTE

• DTC marked with (*) is detected by ECM, transmitted through CAN to ICM and indicated by ICM.

ECM does not indicate (*) marked DTC.

• Immobilizer control module detects DTC B1705 when ignition switch is turned on by using remote

controller of keyless start control system (not using the ignition key). It is not abnormal.
