Rear view camera signals are transmitted from the rear view camera to the AV control unit using the camera signal circuits.

1. CHECK REVERSE POSITION INPUT SIGNAL 
   NOTE: Apply parking brake before proceeding.
   1. Turn ignition switch ON.
   2. Shift transmission into Reverse.
   3. Check voltage between AV control unit harness connector M46 terminal 28 and ground.

   (+)		(-)	Transmission position	Value (Approx.)
   Connector	Terminal
   M46	28	Ground	Reverse	12 V

   Is voltage reading as specified?

   YES

   GO TO 2

   NO

   Check harness for open or short between AV control unit and back-up lamp relay.

2. CHECK CAMERA IMAGE SIGNAL CIRCUIT CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect AV control unit connector M46 and rear view camera connector D411.
   3. Check continuity between AV control unit harness connector M46 terminals 33, 35, 36 and rear view camera harness connector D411 terminals 2, 3 and 4.

      M46 33 - D411 2	: Continuity should exist.
      M46 35 - D411 4	: Continuity should exist.
      M46 36 - D411 3	: Continuity should exist.

   4. Check continuity between AV control unit harness connector M46 terminals 33, 35, 36 and ground.

      M46 33, 35, 36 - Ground

      : Continuity should not exist.

   Is inspection result OK?
