Intermittents

Bad and intermittent electrical connections can cause dash warning light and ECU LED to illuminate, even though no apparent problem exists. To troubleshoot this condition:

1. Note LED display codes.
2. Check connectors associated with items mentioned in "Possible Cause" column. Clean or repair connections as needed.
3. Clear ECU trouble codes.
