Diagnosis Procedure

WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

CHECK REVERSE POSITION INPUT SIGNAL

NOTE: Apply parking brakes before proceeding.

Turn ignition switch ON.
Shift transmission into reverse.

Check voltage between AV control unit harness connector M166 terminal 105 and ground.

(+)		(-)	Transmission position	Value (Approx.)
Connector	Terminal	(-)	Transmission position	Value (Approx.)
M166	105	Ground	Reverse	12V

Is voltage reading approximately 12 volts?

YES: GO TO 2

NO: Check harness for open or short between AV control unit and back-up lamp relay.

CHECK CAMERA IMAGE SIGNAL CIRCUIT CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect AV control unit connector M164 and rear view camera connector D504.
3. Check continuity between AV control unit harness connector M164 terminals 64, 65, 72 and rear view camera harness connector D504 terminals 3, 5 and 6.
  64 - 5: Continuity should exist.
  
  65 - 6: Continuity should exist.
  
  72 - 3: Continuity should exist.
4. Check continuity between AV control unit harness connector M164 terminals 64, 65, 72 and ground.
  64, 65, 72 - Ground: Continuity should not exist.
  
  Is inspection result OK?
  
  YES: GO TO 3
  
  NO: Repair harness or connector.
