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
