Pending and Confirmed DTC

  1. With ignition switch turned OFF, connect CAN communication OBD generic scan tool or SUZUKI scan tool to DLC.
  2. Turn ignition switch to ON position.
  3. Erase DTC and pending DTC according to instructions displayed on scan tool. Freeze frame data is cleared together with DTC. 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 .

  4. After completing the clearance, turn OFF ignition switch and disconnect scan tool from DLC.
    NOTE: Pending and confirmed DTC and freeze frame data stored in ECM memory are also cleared in the following cases.
    Be careful not to clear them before recording them.
    • When power to ECM is cut off (by disconnecting battery cable, removing fuse or disconnecting ECM (connectors)).
    • When the same malfunction (DTC) is not detected again during 40 engine warm-up cycles (refer to WARM-UP CYCLE OF ON-BOARD DIAGNOSTIC (OBD) SYSTEM DESCRIPTION: J24B ).
    • Even though the pending and confirmed DTCs are cleared, the permanent DTC will not be cleared.
