Check the wiring

Faults in the control module's female connector could be the cause of the diagnostic trouble code. Check the connector for oxidation, dislodged pins and pin clamping force.

Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits in the wiring harness. Monitor the multimeter, the diagnostic tool or test lamp during the check. In addition, check contacts, connectors and crimp connections for oxidation, dislodged pins and pin clamping force.
