Diagnosis Procedure

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

1. CHECK REVERSE INPUT SIGNAL 
   1. Turn ignition switch ON.
   2. Shift the selector lever to R (reverse).
   3. Check voltage between AV control unit connector M97 and ground.

      AV control unit		Ground	Condition	Voltage (Approx.)
      Connector	Terminal
      M97	28	-	Selector lever in R (reverse)	Battery Voltage

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: Repair or replace harness or connectors.

2. CHECK CAMERA POWER SUPPLY CIRCUIT CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect AV control unit connector M97 and rear view camera connector.
   3. Check continuity between AV control unit connector M97 and rear view camera connector D506.

      AV control unit		Rear view camera		Continuity
      Connector	Terminal	Connector	Terminal
      M97	34	D506	1	Yes

   4. Check continuity between AV control unit connector M97 and ground.

      AV control unit		Ground	Continuity
      Connector	Terminal
      M97	34		No

      Is the inspection result normal? 

      YES: GO TO 3.

      NO: Repair or replace harness or connectors.

3. CHECK CAMERA POWER SUPPLY VOLTAGE 
   1. Connect AV control unit connector M97 and rear view camera connector.
   2. Turn ignition switch ON.
   3. Shift the selector lever to R (reverse).
   4. Check voltage between AV control unit connector M97 and ground.

      AV control unit		Ground	Condition	Voltage (Approx.)
      Connector	Terminal
      M97	34	-	Selector lever is in "R".	6.0 V

      Is the inspection result normal? 

      YES: GO TO 4.

      NO: Replace AV control unit. Refer to "REMOVAL AND INSTALLATION ".

4. CHECK CAMERA IMAGE SIGNAL CIRCUIT CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect AV control unit connector M97 and rear view camera connector.
   3. Check continuity between AV control unit connector M97 and rear view camera connector D506.

      AV control unit		Rear view camera		Continuity
      Connector	Terminal	Connector	Terminal
      M97	36	D506	3	Yes

   4. Check continuity between AV control unit connector M97 and ground.

      AV control unit		Ground	Continuity
      Connector	Terminal
      M97	36		No

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair or replace harness or connectors.

5. CHECK CAMERA GROUND CIRCUIT CONTINUITY 

   Check continuity between AV control unit connector M97 and rear view camera connector D506.

   AV control unit		Rear view camera		Continuity
   Connector	Terminal	Connector	Terminal
   M97	35	D506	4	Yes

   Is the inspection result normal? 

   YES: GO TO 6.

   NO: Repair or replace harness or connectors.

6. CHECK CAMERA IMAGE SIGNAL 
   1. Connect AV control unit connector M97 and rear view camera connector.
   2. Turn ignition switch ON.
   3. Shift the selector lever to R (reverse).
   4. Check signal between AV control unit connector M97 and ground.

      AV control unit Connector M97		Condition	Reference value
      (+)	(-)
      Terminal	Terminal
      36	35	Camera image displayed.

      Is the inspection result normal? 

      YES: Replace AV control unit. Refer to "REMOVAL AND INSTALLATION ".
