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

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.

S6JB0AA324003

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) Clear DTC(s) according to the instructions displayed 

on SUZUKI scan tool.

5) After completing the clearance, turn the ignition 

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

Diagnostic Trouble Code (DTC) Table

S6JB0AA324004

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.
