CANCEL OUT DIAGNOSTIC TROUBLE CODE
1. After repair of the trouble area, the diagnostic trouble
code retained in memory by the ECM must be canceled
by removing the MFI fuse
(1 5A) for 10 seconds or more,
HINT:
• Cancellation can be also done by removing the battery
negative (–) terminal, but in this case other memory
systems will be also canceled out.
• The diagnostic trouble code can be also canceled out
by disconnecting the ECM connector.
• If the diagnostic trouble code is not canceled out, it will
be retained by the ECM 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 O/D OFF light.
