C1282 Yaw Rate & Lateral G Sensor-Electrical - W/Harness Inspection

Terminal and Connector Inspection

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

Check for open in harness
1. IG "OFF"
2. Disconnect Yaw-rate & Lateral G & Longitudinal G sensor connector and HECU connector.
3. Measure resistance between power terminal of the Yaw-rate & Lateral G & Longitudinal G sensor harness connector and power terminal of the HECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specifications?






Ground Circuit Inspection

Check for open in harness
1. IG "OFF"
2. Disconnect Yaw-rate & Lateral G & Longitudinal G sensor connector and HECU connector.
3. Measure resistance between ground terminal of the Yaw-rate & Lateral G & Longitudinal G sensor harness connector and ground terminal of the HECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specifications?






Signal Circuit Inspection

Check for open in harness
1. IG "OFF"
2. Disconnect Yaw-rate & Lateral G & Longitudinal G sensor connector and HECU connector.
3. IG "ON"
4. Measure resistance between CAN-High terminal of the sensor harness connector and CAN-High terminal of the HECU harness connector.
5. Measure resistance between CAN-Low terminal of the sensor harness connector and CAN-Low terminal of the HECU harness connector.

Specification : Below approx. 1 Ohms




6. Is the measured value within specifications?





Check for short in harness
1. IG "OFF"
2. Disconnect Yaw-rate & Lateral G & Longitudinal G sensor connector and HECU connector.
3. Measure resistance between CAN-High terminal and CAN-Low terminal of the sensor harness connector.

Specification : Infinite




4. Is the measured value within specifications?
