STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT


Description

- Steering angle sensor signal 1, 2 detects the turning direction and quantity of the steering and transmits it to the camera control unit.
- Steering angle sensor signal 3 detects the neutral position of the steering and transmits it to the camera control unit.
- Camera control unit performs the correction of neutral position with sensor signal 1, 2, 3 and vehicle speed signal.




STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT


Diagnosis Procedure

1.CHECK CONTINUITY STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect camera control unit connector and steering angle sensor connector.
3. Check continuity between camera control unit harness connector and steering angle sensor harness connector.





4. Check continuity between camera control unit harness connector and ground.

NO - Replace camera control unit.
3.CHECK SENSOR SIGNAL 1, 2
1. Connect steering angle sensor connector.
2. Check signal between camera control unit harness connector and ground.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace steering angle sensor.
