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?






Signal Circuit Inspection

Check shorted to battery in signal circuit.
1. IG KEY OFF.
2. Disconnect Mode switch and TCCM connector.
3. IG KEY ON.
4. Measure voltage between signal terminal of Mode switch and chassis ground.

Specification : 0V





5. Is the measured value within specification ?





Open in signal circuit
1. IG KEY OFF.
2. Disconnect MODE switch and TCCM connector.
3. Measure resistance between one and the other signal terminal of Mode Switch harness connector.

Specification : below 1 Ohm





4. Is the measured value within specification ?






Ground Circuit Inspection

Check open in ground circuit
1. IG KEY OFF.
2. Disconnect Mode switch and TCCM connector.
3. Measure resistance between ground terminal of Mode switch harness connector and chassis ground.

Specification : below 1 Ohm





4. Is the measured value within specification ?
