Terminal and Connector Inspection

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






Signal Circuit Inspection

Open Check
1. Ignition "OFF" & Engine "OFF".
2. Disconnect TPMS ECU, PCM and ABS ECU connector.
3. Measure resistance between CAN HIGH, LOW terminal of the TPMS ECU harness connector and CAN HIGH, LOW terminal terminal of the PCM harness connector.
4. Measure resistance between CAN HIGH, LOW terminal of the TPMS ECU harness connector and CAN HIGH, LOW terminal terminal of the ABS ECU harness connector.
5. Measure resistance between Vehicle speed in terminal of the PCM harness connector and Vehicle speed out terminal of the ABS ECU harness connector.
6. Measure resistance between FR WSS Power terminal of the ABS ECU harness connector and FR WSS Power terminal of the FR WSS harness connector.
7. Measure resistance between FR WSS Signal terminal of the ABS ECU harness connector and FR WSS Signal terminal of the FR WSS harness connector.

Specification :0 Ohms








8. Is the measured resistance within specifications?
