STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT
STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT
Description
INFOID:0000000000964877
• 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:0000000000964878
