Clearing Diagnostic Trouble Codes

CAUTION: When battery is disconnected, vehicle computer and memory system may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See appropriate COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

CAUTION: Record DTCs and freeze frame data before erasing DTCs, or freeze frame data will be lost.

DTCs may be cleared by using Hi-Scan Pro tool or equivalent scan tool, or by disconnecting negative battery cable. Clearing DTCs will also clear freeze frame data. Turn ignition off. Disconnect negative battery cable for at least 20 seconds. Reconnect negative battery cable. Verify DTCs have been erased.
