Fault symptom

•	Check Engine on when ignition switch next turned on.

Conditions

The following conditions apply for the DTC in question:

•

A check of the main relay circuit is performed in the afterrun function. When the control module stops grounding pin 58 to the main relay, a clock starts. If it takes longer than two seconds for the current to disappear from pin 3 after the grounding has ceased, the diagnostic trouble code will be generated the next time the ignition is turned on.

Diagnostic help

The diagnostic trouble code can be generated if the relay coil ground lead is shorted to ground or if the main relay circuit is shorted to B+.
