With Generic Scan Tool

DTC Check

NOTE:
The MIL is turned on when the ECM and/or TCM detect malfunction(s). Each ECM and TCM stores diagnostic information as the diagnostic trouble code (DTC) in its memory and outputs the DTC to the scan tool.
Therefore, check both of the ECM and TCM for any DTC with the scan tool because the DTC stored in ECM and TCM is not read and displayed at a time. However, each of the ECM and TCM needs not to be checked with the generic scan tool because the DTC stored in ECM and TCM is read and displayed at a time.

1. Prepare CAN communication OBD-II generic scan tool or SUZUKI scan tool.

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

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





3. Turn ignition switch ON 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 Error with Scan Tool Using CAN. Scan Tool Testing and Procedures
5. After completing the check, turn ignition switch off and disconnect scan tool from DLC.
