REAR VIEW CAMERA POWER SUPPLY

Description

INFOID:0000000003882757

• 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:0000000003901214

CAMERA IMAGE SIGNAL CIRCUIT

CAMERA IMAGE SIGNAL CIRCUIT

Description

INFOID:0000000003882759

• 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 dis-

play unit.

Diagnosis Procedure

INFOID:0000000003901215

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.

COMPOSITE IMAGE SIGNAL CIRCUIT

Description

INFOID:0000000003882761

AV control unit that inputs the camera image signal and AUX image signal transmits the composite image sig-
nal to the display unit.

Diagnosis Procedure

INFOID:0000000003901216

1.

CHECK CONTINUITY COMPOSITE IMAGE SIGNAL CIRCUIT (AV CONTROL UNIT TO DISPLAY UNIT)

1.

Turn ignition switch OFF.

2.

Disconnect AV control unit connector and display unit connector.

3.

Check continuity between AV control unit harness connector and display unit harness connector.

4.

Check continuity between AV control unit harness connector and ground.

Is inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK COMPOSITE IMAGE SIGNAL (AV CONTROL UNIT TO DISPLAY UNIT)

1.

Connect AV control unit connector and display unit connector.

2.

Turn ignition switch ON.

3.

Check signal between AV control unit harness connector using an oscilloscope.

Is inspection result normal?

YES

>> Replace display unit.

NO

>> Replace AV control unit.

STEERING ANGLE SENSOR SIGNAL CIRCUIT

STEERING ANGLE SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000003939943

• 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:0000000003939944

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.
