Terminal And Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) 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: 

   • Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   No: 

   • Go to CAN High line Inspection procedure.

CAN HIGH LINE INSPECTION 

1. Check for Open in harness.

   [With ABS]

   1. Ignition "OFF".
   2. Measure resistance between terminals 7 of the PCM harness connectors and 11 of the ABS control module harness connector.

      Specification: Approx. 0Ω
