REAR VIEW CAMERA POWER SUPPLY
REAR VIEW CAMERA POWER SUPPLY
DescriptionINFOID:0000000003838249
 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 ProcedureINFOID:0000000003901194
1.CHECK CONTINUITY CAMERA ON SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect camera control unit connector and rear view camera connector.
3. Check continuity between camera control unit harness connector and rear view camera harness connec-
tor.
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 VOLTAGE CAMERA ON SIGNAL
1. Connect camera control unit connector and rear view camera connector.
2. Turn ignition switch ON.
3. Check signal between camera control unit harness connector and ground.
Is inspection result normal?
YES >> Replace rear view camera.
NO >> Replace camera control unit.

STEERING ANGLE SENSOR SIGNAL CIRCUIT
DescriptionINFOID: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 ProcedureINFOID: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.
