Clearing Trouble 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 No. 6 ECT CLOCK (1OA) 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 systems (ECM diagnosis memory, etc.) will also be canceled out.
^ The diagnostic code can also be canceled 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 on 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.
