Check Door Switch/With Navigation System

First perform the "SELF-DIAG RESULTS" in "BCM" with CONSULT-II, when perform the each trouble diagnosis. Refer to  CAN COMMUNICATION INSPECTION USING CONSULT-II  .  

1. CHECK DOOR SWITCH INPUT SIGNAL 

   Check voltage between combination meter connector and ground.

   TERMINAL VOLTAGE
   
   

   Item	Connector	Terminals (Wire color)		Condition	Voltage [V] (Approx.)
   		(+)	(-)
   Driver side	M19	7 (W)	Ground	CLOSE "DOWN ARROW" OPEN	Battery voltage "DOWN ARROW" 0
   Passenger side		6 (P)
   Rear LH		9 (P)
   Rear RH		8 (P)

   OK or NG 

   1. OK: Door switch circuit is OK.
   2. NG: GO TO 2.
2. CHECK DOOR SWITCH 
   1. Turn ignition switch OFF.
   2. Disconnect door switch and combination meter connector.
   3. Check continuity between door switch connector B17, B23, B20, B32 terminals 1 and combination meter connector M19 terminals 7, 6, 9, 8.

      Front door switch driver side 

      1 (W) - 7 (W): Continuity should exist. 

      Front door switch passenger side 

      1 (P) - 6 (P): Continuity should exist. 

      Rear door switch LH 

      1 (P) - 9 (P): Continuity should exist. 

      Rear door switch RH 

      1 (P) - 8 (P): Continuity should exist. 

   4. Check continuity between door switch connector B17, B23, B20, B32 terminals 1 and ground.

      1 (W or P) - Ground: Continuity should not exist

   OK or NG 

   1. OK: GO TO 3.
   2. NG: Repair or replace harness.
3. CHECK DOOR SWITCH 

   Check continuity between each door switch terminal 1 and body ground part of door switch.

   TERMINAL CONTINUITY
   
   

   Terminal		Door switch	Continuity
   1	Body ground part of door switch	Pushed	No
   		Released	Yes

   OK or NG 

   1. OK: GO TO 4.
   2. NG: Replace door switch.
4. CHECK COMBINATION METER OUTPUT SIGNAL 
   1. Connect combination meter connector.
   2. Check voltage between combination meter connector M19 terminals 6, 7, 8, 9 and ground.

      6 (P) - Ground: Battery voltage 

      7 (W) - Ground: Battery voltage 

      8 (P) - Ground: Battery voltage 

      9 (P) - Ground: Battery voltage

   OK or NG 

   1. OK: Check harness connection.
   2. NG: Replace combination meter.
