STEERING ANGLE SENSOR SIGNAL CIRCUIT
Description
INFOID:0000000005528568
• 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 con-
trol unit.
• Camera control unit performs the correction of neutral position with sensor signal 1, 2, 3 and vehicle speed
signal.
Diagnosis Procedure
INFOID:0000000005528569
1.
CHECK CONTINUITY STEERING ANGLE SENSOR SIGNAL 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 con-
nector.
4.
Check continuity between camera control unit harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 2.
