PREDICTED COURSE LINE OPERATION PRINCIPLE
Detection Of Steering Rotation Direction
Camera control unit detects the rotation direction of steering according to the phase difference of two pairs of
pulse signals (sensor signal 1 and sensor signal 2) input from steering angle sensor.
Detection Of Steering Neutral Position
The sensor signal 3 input from steering angle sensor is generated at 1 pulse per 1 rotation of the steering
wheel. Camera control unit detects the steering neutral position from this pulse.
Correction Of Steering Neutral Position
Camera control unit corrects the steering neutral position during driving according to the vehicle speed signal
and sensor signal.

Component DescriptionINFOID:0000000003791251
Part name Description
AV CONTROL UNIT Image on display is transmitted to rear view monitor image by serial communi-
cation between AV control unit and display unit.
 AV control unit recognizes the presence of camera system with camera con-
nection recognition signal.
DISPLAY UNIT Camera image signal is input from AV control unit.
 Rear view monitor image is changed by serial communication from AV control
unit.
CAMERA CONTROL UNIT Camera image signal is input from rear view camera. Camera image signal is
output to AV control unit.
 Power supply is transmitted to rear view camera.
 Superimposes the guiding line and predicted course line to the camera image
that outputs to AV control unit.
 Inputs the sensor signal from steering angle sensor, and then controls the pre-
dicted course line.
 Camera control unit is connected via AV communication.
REAR VIEW CAMERA The image of vehicle rear view is transmitted to camera control unit.
 It receives power supply from camera control unit and operates.
STEERING ANGLE SENSORSteering signal necessary for predicted course line control is transmitted to cam-
era control unit.

STEERING ANGLE SENSOR SIGNAL CIRCUIT
DescriptionINFOID:0000000003765727
 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 ProcedureINFOID:0000000003901197
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 inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK SIGNAL SENSOR SIGNAL
1. Connect camera control unit connector.
2. Turn ignition switch ON.
3. Check voltage between camera control unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 3.
NO >> Replace camera control unit.
3.CHECK SIGNAL SENSOR SIGNAL
1. Turn ignition switch OFF.
2. Connect steering angle sensor connector.
