Terminal and Connector Inspection

  1. Many malfunctions in the electrical system are caused by poor harness and terminal connections.

    Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

  2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
  3. Has a problem been found?

    YES 

    NO 

    • Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair " procedure.
