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.

4.

Check continuity between around view monitor 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 around view monitor control unit connector and display unit connector.

2.

Turn ignition switch ON.

3.

Check signal between around view monitor control unit harness connector and ground.

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?

YES

>> GO TO 3.

NO

>> Replace camera control unit.

WITH AROUND VIEW MONITOR

WITH AROUND VIEW MONITOR : Description

INFOID:0000000003514103

• Steering angle sensor signal 1, 2 detects the turning direction and quantity of the steering and transmits it to

the around view monitor control unit.

• Steering angle sensor signal 3 detects the neutral position of the steering and transmits it to around view

monitor control unit.

• Around view monitor control unit performs the correction of neutral position with sensor signal 1, 2, 3 and

vehicle speed signal.
