CAMERA IMAGE SIGNAL CIRCUIT
Description
INFOID:0000000003765723
• 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 AV
control unit.
Diagnosis Procedure
INFOID:0000000003901195
1.
CHECK CONTINUITY CAMERA IMAGE SIGNAL CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect camera control unit connector and AV control unit connector.
3.
Check continuity between camera control unit harness connector and AV control unit harness connector.
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 CAMERA IMAGE SIGNAL
1.
Connect camera control unit connector and AV control unit connector.
2.
Turn ignition switch ON.
3.
Check signal between camera control unit harness connector using an oscilloscope.
Is inspection result normal?
YES
>> Replace AV control unit.
NO
>> Replace camera control unit.

STEERING ANGLE SENSOR SIGNAL CIRCUIT
Description
INFOID: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 Procedure
INFOID: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.
