Diagnosis Procedure

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

1. CHECK REMOTE KEYLESS ENTRY RECEIVER OUTPUT SIGNAL 
   1. Turn ignition switch OFF.
   2. Check signal between BCM harness connector and ground using oscilloscope.

      (+)		(-)	Condition	Signal (Reference value)
      BCM
      Connector	Terminal
      M80	119	Ground	Standby state
      			Press the Intelligent Key lock or unlock button

      Is the inspection result normal? 

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

      NO: GO TO 2.

2. CHECK REMOTE KEYLESS ENTRY RECEIVER CIRCUIT 1 
   1. Disconnect BCM and remote keyless entry receiver connectors.
   2. Check continuity between BCM harness connector and remote keyless entry receiver harness connector.

      BCM		Remote keyless entry receiver		Continuity
      Connector	Terminal	Connector	Terminal
      M80	119	M86	2	Yes

   3. Check continuity between BCM harness connector and ground.

      (+)		(-)	Continuity
      BCM
      Connector	Terminal
      M80	119	Ground	No

      Is the inspection result normal? 

      YES: GO TO 3.

      NO: Repair or replace harness.

3. CHECK REMOTE KEYLESS ENTRY RECEIVER POWER SUPPLY 

   Check voltage between remote keyless entry receiver harness connector and ground.

   (+)		(-)	Voltage Approx.
   Remote keyless entry receiver
   Connector	Terminal
   M86	1	Ground	Battery voltage

   Is the inspection result normal? 

   YES: GO TO 4.

   NO-1: Check 10A fuse No. 25 [located in fuse block J/B].

   NO-2: Repair or replace harness between remote keyless entry receiver and 10A fuse No. 25.

4. CHECK REMOTE KEYLESS ENTRY RECEIVER GROUND CIRCUIT 

   Check continuity between remote keyless entry receiver harness connector and ground.

   Remote keyless entry receiver		Ground	Continuity
   Connector	Terminal
   M86	3		Yes

   Is the inspection result normal? 

   YES: Replace remote keyless entry receiver. Refer to "REMOVAL AND INSTALLATION ".

   NO: Repair or replace harness.
