W/Harness Inspection

Motor driven Power Steering
C1101 Battery Voltage High - Inspection/Repair:_: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?






Charging Circuit Inspection

1. Engine "ON", headight and heatwire "ON".
2. Measure voltage between the battery (+) and (-) while maintaining ENG. RPM at 2,500 (idle) over 2 minutes.
Specification :









3. Is the measured voltage within specifications?






Power Circuit Inspection

1. Ignition "OFF"
2. Disconnect EPS CM connector.
3. Engine "ON",
4. Measure voltage between ON/START INPUT terminal of EPS CM harness connector and chassis ground.

Specification: Battery Voltage








5. Is the measured voltage within specifications?






Ground Circuit Inspection

1. Ignition "OFF".
2. Disconnect EPS CM connector.
3. Measure resistance between ground terminal of EPS CM harness connector and chassis ground.

Specification: Approx. 0 Ohms




> Check for open and contact resistance in ground harness.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
