W/Harness Inspection

Electric Parking Brake
C1102 Battery Voltage Low - 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 System Inspection

1. Engine "ON"
2. headlight and heatwire "ON".
3. Measure voltage between terminal (+) and (-) of battery maintaining ENG. RPM at 2,500 RPM (idle) over 2 minutes.

Specification : More than 10 [V]

4. Is the measured voltage within specifications?






Power Circuit Inspection

Open or Short Check
1. Ignition "OFF"
2. Disconnect EPB ECU connector.
3. Engine "ON", headlight and heatwire "ON".
4. Measure voltage between battery power terminal of EPB ECU harness connector and chassis ground maintaining ENG. RPM at 2,500 RPM (idle) over 2 minutes.

Specification : More than 10 [V]




5. Is the measured voltage within specifications?






Ground Circuit Inspection

Open or Short Check
1. Ignition "OFF".
2. Disconnect EPB ECU connector.
3. Measure resistance between ground terminal of EPB ECU harness connector and chassis ground.

Specification : Approx. 1.0 Ohms




4. Is the measured resistance within specifications?
