WITH AROUND VIEW MONITOR : Description
INFOID:0000000003513842
• Around view monitor control unit supplies to the front camera, rear camera and side camera. And then it
superimpose the images from each camera and outputs then to the display unit.
• Superimpose the guiding lines, predicted course line and sonar indicator to the camera image that outputs to
the display unit.
• Around view monitor control unit performs the reception/transmission of communication signal with each
camera.
WITH AROUND VIEW MONITOR : Diagnosis Procedure
INFOID:0000000003415753
1.
CHECK CONTINUITY CAMERA IMAGE SIGNAL CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect around view monitor control unit connector and display unit connector.
3.
Check continuity between around view monitor control unit harness connector and display unit harness
connector.

STEERING ANGLE SENSOR SIGNAL CIRCUIT
WITH REAR VIEW MONITOR
WITH REAR VIEW MONITOR : Description
INFOID:0000000003160727
• 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.
WITH REAR VIEW MONITOR : Diagnosis Procedure
INFOID:0000000003160728
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?
