W/Harness Inspection
Terminal and Connector Inspection
1. Many malfunctions in the electrical system are caused by poor harness(es) 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
1) Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Go to "Signal circuit inspection" procedure.
Signal Circuit Inspection
1. Ignition "OFF".
2. Disconnect HECU connector.
3. Measure resistance between terminal "14" of the HECU harness connector and terminal "9,38" of the HECU harness connector. (In case of ESC)
A. Specification : Approx. below 1 Ohm
4. Is the measured resistance within specifications?
YES
1) Go to "Component Inspection" procedure.
NO
1) Check for open or short to GND in pin coding harness. Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
