Without Scan Tool

DIAGNOSTIC TROUBLE CODE (DTC) CLEARANCE WITHOUT USING SCAN TOOL

DTC and freeze frame data stored in ECM (PCM) memory are also cleared in following cases. Be careful not to clear them before keeping their record.
- When power to ECM (PCM) is cut off (by disconnecting battery cable, removing fuse or disconnecting ECM (PCM) 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 SYSTEM")
