STEERING ANGLE SENSOR SIGNAL CIRCUIT


Description

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




STEERING ANGLE SENSOR SIGNAL CIRCUIT


Diagnosis Procedure

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





4. Check continuity between around view monitor control unit harness connector and ground.





Is inspection result normal?
YES - GO TO 2.
NO - Repair harness or connector.
2.CHECK SIGNAL SENSOR SIGNAL
1. Connect around view monitor control unit connector.
2. Turn ignition switch ON.
3. Check voltage between around view monitor control unit harness connector and ground.





Is inspection result normal?
YES - GO TO 3.
NO - Replace around view monitor control unit.
3.CHECK SIGNAL SENSOR SIGNAL
1. Turn ignition switch OFF.
2. Connect steering angle sensor connector.
3. Turn ignition switch ON.
4. Check signal between around view monitor control unit harness connector and ground.





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