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:
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.
- CAN communication OBD 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.
2) Turn ignition switch to OFF position.
3) Connect scan tool to DLC (1).
