Clearing Trouble Codes

CANCELING DIAGNOSTIC CODES




1. After repair of the trouble area, the diagnostic code retained in memory by the ECT computer must be canceled by removing the fuse AM2 (7.5 A) for 10 seconds or more, depending on ambient temperature (the lower the temperature, the longer the fuse must be left out) with the ignition switch off.

NOTE:
- Cancellation can also be done by removing the battery negative (-) terminal, but in this case other memory system (clock, radio ETR, etc.) will also be cancelled out.
- The diagnostic code can also be cancelled out by disconnecting the ECT computer connector.
- If the diagnostic code is not cancelled out, it will be retained by the ECT computer and appear along with a new code in event of future trouble.

2. After cancellation, perform a road test to confirm that a "normal code" is now read on the OD "OFF" light.
