Inspection/Repair - W/Harness Inspection

Terminal & Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal conditions. 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?






Control Circuit Inspection

Short to battery in control circuit
1. IG KEY OFF.
2. Disconnect EMC and TCCM connector.
3. IG KEY ON.
4. Measure voltage between control terminal of EMC harness connector and chassis ground.

Specification : 0V





5. Is the measured value within specification ?





Open in control circuit
1. IG KEY OFF.
2. Disconnect EMC and TCCM connector.
3. Measure resistance between control terminal of one and the other of EMC harness connector.

Specification : below 1 Ohm





4. Is the measured voltage within specification ?






Ground Circuit Inspection

Check open in ground circuit
1. IG KEY OFF.
2. Disconnect EMC and TCCM connector.
3. Measure resistance between ground terminal of one and the other of EMC harness connector.

Specification : below 1 Ohm





4. Is the measured value within specification ?
