W/Harness Inspection

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 all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration and/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 "Power Supply Circuit Inspection" procedure.

Power Supply Circuit Inspection

1. Ignition "OFF"
2. Disconnect solenoid connector.
3. Measure resistance between terminal "1" of solenoid harness connector and terminal "1" of EPS CM harness connector.
A. Specification : Approx. 0 Ohm




4. Is the measured resistance within specifications ?
YES
1) Check for short to ground in power harness.
-> If it is normal, go to "Control Circuit Inspection" procedure.
-> If it is abnormal, repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check for open in power harness.
2) Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

Control Circuit Inspection

1. Ignition "OFF".
2. Disconnect solenoid connector and EPS CM connector.
3. Measure resistance between terminal "2"of solenoid harness connector and terminal "2" of EPS CM harness connector.
A. Specification : Approx. 0 Ohm




4. Is the measured resistance within specifications ?
YES
1) Check for short to ground in control harness.
-> If it is normal, go to "Component Inspection" procedure.
-> If it is abnormal, repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check for open/short to ground in control harness.
2) Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
