Terminal and Connector Inspection

  1. Many malfunctions in the electrical system are caused by poor harness and terminals. 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 then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
