W/Harness Inspection

Brake

ABS/ESC - C1643 CAN Time-out Yaw Rate & Lateral G Sensor - 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 "OFF"
2. Disconnect Yaw rate & Lateral G sensor connector.
3. Measure voltage between terminal "1" of the Yaw rate & Lateral G sensor harness connector and chassis ground.

Specification : Approx. Battery voltage




4. Is the measured voltage within specifications?






Ground Circuit Inspection

1. Ignition "OFF"
2. Disconnect the yaw rate & lateral G sensor harness 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?






CAN Circuit Inspection

1. Ignition "OFF".
2. Disconnect the HECU harness connector and yaw rate & lateral G sensor harness connector.
3. Measure resistance between terminal "35" of the HECU harness connector and terminal "2" of the yaw rate & lateral G sensor harness connector.
4. Measure resistance between terminal "14" of the HECU harness connector and terminal "3" of the yaw rate & lateral G sensor harness connector.

Specification : Approx. below 1 Ohms




5. Is the measured resistance within specifications?
