W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) 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?






Power Circuit Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure voltage between terminal "1" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.

Specification : Approx. B+




3. Is the measured voltage within specifications?






Ground Circuit Inspection

1. Ignition "OFF".
2. Disconnect Yaw Rate & Lateral G sensor connector.
3. Measure resistance between terminal "4" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.

Specification : Approx. below 1 Ohms




4. Is the measured resistance within specifications?






Signal Circuit Inspection

1. Ignition "OFF".
2. Disconnect the HECU harness connector and yaw rate & lateral G sensor harness connector.
3. Measure resistance between CAN HIGH terminal of the HECU harness connector and CAN HIGH terminal of the yaw rate & lateral G sensor harness connector.
4. Measure resistance between CAN LOW terminal of the HECU harness connector and CAN LOW terminal of the yaw rate & lateral G sensor harness connector.

Specification : Approx. below 1 Ohms




5. Is the measured resistance within specifications?
