Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 1
   
   
   1. Turn ignition switch OFF.
   2. Check signal between BCM harness connector and ground using oscilloscope.

      (+)		(-)	Condition		Signal (Reference value)
      BCM
      Connector	Terminal
      B16	61, 64	Ground	When the driver door request switch is operated with ignition switch OFF.	When Intelligent Key is in the antenna detection area. (The distance between Intelligent Key and antenna: 80 cm or less.)	Courtesy of NISSAN NORTH AMERICA, INC.
      				When Intelligent Key is not in the antenna detection area. (The distance between Intelligent Key and antenna: Approx. 2 m.)	Courtesy of NISSAN NORTH AMERICA, INC.

   Is the inspection result normal?

   YES 

   Replace BCM. Refer to REMOVAL AND INSTALLATION .

   NO 

   GO TO STEP 2  .

2. CHECK OUTSIDE KEY ANTENNA CIRCUIT
   
   
   1. Disconnect BCM connector and outside key antenna (rear bumper) connector.
   2. Check continuity between BCM harness connector and outside key antenna (rear bumper) harness connector.

      BCM		Outside key antenna (rear bumper)		Continuity
      Connector	Terminal	Connector	Terminal
      B16	64	B76	1	Yes
      	61		2

   3. Check continuity between BCM harness connector and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      B16	64		No
      	61

   Is the inspection result normal?

   YES 

   GO TO STEP 3  .

   NO 

   Repair or replace harness.

3. CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 2
   
   
   1. Replace outside key antenna (rear bumper). (New antenna or other antenna)
   2. Connect BCM and outside key antenna (rear bumper) connector.
   3. Check signal between BCM harness connector and ground using oscilloscope.

      (+)		(-)	Condition		Signal (Reference value)
