Diagnosis Procedure

Regarding Wiring Diagram information, refer to the appropriate 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
      M80	114, 115	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

   .

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

      BCM		Outside key antenna (RH)		Continuity
      Connector	Terminal	Connector	Terminal
      M80	114	D116	1	Yes
      	115		2

   3. Check continuity between BCM harness connector and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M80	114		No
      	115

   Is the inspection result normal?

   YES

   .

   NO

   Repair or replace harness.

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

      (+)		(-)	Condition		Signal (Reference value)
      BCM
      Connector	Terminal
      M80	114, 115	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.
