CAMERA IMAGE SIGNAL CIRCUIT (CAMERA CONTROL UNIT TO FRONT
DISPLAY UNIT)
Description
INFOID:0000000003356659
• Camera control unit outputs camera ON signal to rear view camera and inputs rear view camera image sig-
nal from rear view camera when the reverse signal is input.
• The camera control unit that inputs the camera image signal transmits the camera image signal to the front
display unit.
Diagnosis Procedure
INFOID:0000000003356660
1.
CHECK CONTINUITY CAMERA IMAGE SIGNAL CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect camera control unit connector and front display unit connector.
3.
Check continuity between camera control unit harness connector and front display unit harness connec-
tor.
4.
Check continuity between camera control unit harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair harness or connector.
2.
CHECK CAMERA IMAGE SIGNAL
1.
Connect camera control unit connector and front display unit connector.
2.
Turn ignition switch ON.
3.
Check signal between camera control unit harness connector and ground using an oscilloscope.
Is the inspection result normal?
YES
>> Replace front display unit.
NO
>> Replace camera control unit.

STEERING ANGLE SENSOR SIGNAL CIRCUIT
STEERING ANGLE SENSOR SIGNAL CIRCUIT
Description
INFOID:0000000003566413
• 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.

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.
NO
>> Repair harness or connector.
2.
CHECK VOLTAGE CAMERA CONTROL UNIT
1.
Connect camera control unit connector.
2.
Turn ignition switch ON.
3.
Check voltage between camera control unit harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace camera control unit.
3.
