CAMERA IMAGE SIGNAL CIRCUIT (REAR VIEW CAMERA TO CAMERA
CONTROL UNIT)

Description

INFOID:0000000000947110

• 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:0000000000947111

1.

CHECK CONTINUITY CAMERA IMAGE 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 terminal 10 and rear view camera har-
ness connector terminal 3.

4.

Check continuity between camera control unit harness connector terminal 10 and ground.

Is inspection result OK?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK CAMERA IMAGE 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 terminal 10 and ground.

Is inspection result OK?

YES

>> Replace camera control unit.

NO

>> Replace rear view camera.

10 - 3

: Continuity should exist.
