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 6 and rear view camera har-
ness connector terminal 3.

4.

Check continuity between camera control unit harness connector terminal 6 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 6 and ground.

Is inspection result OK?

YES

>> Replace camera control unit.

NO

>> Replace rear view camera.
