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.

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 On-Board Diagnostic (OBD) System Description
