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
      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)
      				When Intelligent Key is not in the antenna detection area (The distance between Intelligent Key and antenna: Approx. 2 m)

      Is the inspection result normal? 

      YES: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".

      NO: GO TO 2.

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

      BCM		Outside key antenna (passenger side)		Continuity
      Connector	Terminal	Connector	Terminal
      M80	114	D118	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: GO TO 3.

      NO: Repair or replace harness.

3. CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 2 
   1. Replace outside key antenna (passenger side). (New antenna or other antenna)
   2. Connect BCM connector and outside key antenna (passenger side) 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)
      				When Intelligent Key is not in the antenna detection area (The distance between Intelligent Key and antenna: Approx. 2 m)

      Is the inspection result normal? 

      YES: Replace outside key antenna (passenger side). Refer to "PASSENGER SIDE: REMOVAL AND INSTALLATION ".

      NO: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".
