W/Harness 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 connectors for looseness, poor connection, bending, corrosion, contamination, deterioration,or damage.
3. Has a problem been found?






CAN communication circuit inspection (EHPS ECU <--> Steering angle sensor)

1. Ignition "OFF"
2. Disconnect Steering angle sensor connector and EHPS ECU connector
3. Measure the resistance between CAN-HIGH terminal of Steering angle sensor harness connector and CAN-HIGH terminal of EHPS ECU harness connector.
4. Measure the resistance between CAN-LOW terminal of Steering angle sensor harness connector and CAN-LOW terminal of EHPS ECU harness connector.

Specification :below 1Ohms




5. Is the measured resistance within specification ?
