C1206 Wheel Speed Sensor Rear-LH Open/Short - 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

1. Ignition "ON" & Engine "OFF".
2. Measure voltage between power terminal of the wheel speed sensor harness connector and chassis ground.

Specification : Approx. B+




3. Is the measured value within specifications?






Signal Circuit Inspection

Check for open in harness
1. IG "OFF"
2. Disconnect wheel speed sensor connector and HECU connector.
3. Measure resistance between signal terminal of wheel speed sensor harness connector and signal terminal of HECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specifications?





Check for short in harness
1. IG "OFF"
2. Disconnect wheel speed sensor connector and HECU connector.
3. Measure resistance between signal terminal of wheel speed sensor harness connector and chassis ground.

Specification : Infinite




4. Is the measured value within specifications?
