DTC Check

DTC Check

NOTE:

In case that MIL turns on, the malfunction(s) is detected in either ECM or TCM and it stores the trouble information (DTC, freeze flame data, etc.) in its memory.

According to the varieties of scan tool, check the trouble information as follows.

- SUZUKI scan tool (SUZUKI-SDT):
It is necessary to check both ECM and TCM separately because the trouble information of both modules can not be read and displayed at once.
- Generic scan tool:
It is not necessary to check both ECM and TCM separately because the trouble information of both modules can be read and displayed at once.

1) Prepare CAN communication OBD generic scan tool or SUZUKI scan tool.
Special Tool

(A): SUZUKI scan tool (SUZUKI-SDT)

2) With ignition switch turned OFF, connect it to DLC (1) located on underside of instrument panel at driver's seat side.





3) Turn ignition switch to ON position and confirm that MIL lights.
4) Read DTC and freeze frame data according to instructions displayed on scan tool and print them or write them down. Refer to scan tool operator's manual for details.

If communication between scan tool and ECM is not possible, go to Troubleshooting for Communication Bus Off Troubleshooting for Communication Bus Off.
5) After completing the check, turn OFF ignition switch and disconnect scan tool from DLC.
