ESP (CTC)
C1260 Steering Angle Sensor Circuit-Signal - 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?






Signal Circuit Inspection

Check CAN communication line
1. IG "OFF"
2. Disconnect steering angle sensor connector and HECU connector.
3. Measure resistance between CAN-High terminal of the steering angle sensor harness connector and CAN-High terminal of the HECU harness connector.
4. Measure resistance between CAN-Low terminal of the steering angle sensor harness connector and CAN-Low terminal of the HECU harness connector.

Specification : Below approx. 1 Ohms




5. Is the measured value within specifications?
