W/Harness Inspection

Electronic Stability Control
C1623 CAN Time-out Steering Angle Sensor - Inspection/Repair:_: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

Open or Short Check
1. Ignition "OFF"
2. Disconnect Steering Angle Sensor connector.
3. Ignition "ON" & Engine "OFF"
4. Measure voltage between power terminal of the steering angle sensor harness connector and chassis ground.

Specification :Approx. 12V




5. Is the measured value within specifications?






Ground Circuit Inspection

Open or Short Check
1. Ignition "OFF" & Engine "OFF".
2. Disconnect steering angle sensor connector.
3. Measure resistance between ground terminal of the steering angle sensor harness connector and chassis ground.

Specification :Approx. below 1Ohms




4. Is the measured value within specifications?






Signal Circuit Inspection

Open or Short Check
1. IG "OFF"
2. Disconnect Steering Angle Sensor connector and HECU connector.
3. Measure resistance between CAN-High terminal of Steering Angle Sensor harness connector and CAN-High terminal of HECU harness connector.
4. Measure resistance between CAN-Low terminal of Steering Angle Sensor harness connector and CAN-Low terminal of HECU harness connector.

Specification :Below approx. 1Ohms




5. Is the measured value within specification?
