Reading and Clearing Diagnostic Trouble Codes

Erasing Past Failure Memory




When DTCs are displayed in the past failure indication mode, they remain in the memory after the failed systems are corrected. Consequently, the next time the past failure indication mode is used, the same past failure DTCs will be indicated on the information display. Therefore, erase the past failure memory after correcting all failed systems. To clear the past malfunction memory, press the AUTO and REC switches on the front climate control unit at the same time. Then "01" is displayed. If cleared, "00" will be indicated.
