Clearing Diagnostic Trouble Codes

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

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

When battery is disconnected, vehicle computer memory system may lose memory data. Driveability problems may exist. After disconnecting battery or replacing ECM, drive vehicle to enable ECM to relearn driveability. Inform your customer that they may experience driveability different from what they are accustomed to until ECM completes relearn function.
