Terminal And Connector Inspection

  1. Many malfunctions in the electrical system are caused by poor harness and terminal condition. 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 ECM and check for proper operation. If the problem is corrected, replace ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
    NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM. After testing ECM on the vehicle, use this function before reusing the ECM
