DTC Diagnosis Procedure

Detects door open/close condition.

1. CHECK DOOR SWITCHES INPUT SIGNAL 

   CONSULT

   1. Select "DOOR SW-DR", "DOOR SW-AS", "DOOR SW-RL" or "DOOR SW-RR" in "Data Monitor" mode of "BCM (DOOR LOCK)".
   2. Check that the function operates normally according to the following conditions:

   Monitor Item	Condition		Status
   DOOR SW-DR	Front door LH	Open	On
   		Closed	Off
   DOOR SW-AS	Front door RH	Open	On
   		Closed	Off
   DOOR SW-RL	Sliding door or back doors	Open	On
   		Closed	Off
   DOOR SW-RR	Back door RH	Open	On
   		Closed	Off

   CONSULT

   Close all doors. Check suspect door switch circuit voltage between BCM connector and ground. Cycle suspect door open and closed while monitoring voltage.

   (+)		(-)	Condition		Voltage (approx.)
   BCM
   Connector	Terminals
   M19	47	Ground	Front door switch LH	Open Closed	0 Battery voltage
   	48		Sliding door switch, back door switch lower LH, back door switch lower RH, secondary sliding door switch
   M18	12		Front door switch RH
   	13		Back door switch upper RH

   Is the inspection result normal?

   YES

   Refer to Intermittent Incident .

   NO

   GO TO 2.

2. CHECK DOOR SWITCH CIRCUIT 
   1. Ignition switch OFF.
   2. Disconnect suspect door switch and BCM harness connectors.
   3. With sliding side door closed, check continuity between suspect door switch harness connector and BCM harness connectors.

      BCM		Door switch			Continuity
      Connector	Terminal	Connector		Terminal
      M18	12	Front door switch RH	B108	2	Yes
      	13	Back door switch upper RH (Cargo van)	R21	1
      		Back door switch upper RH (Passenger van)	B70
      M19	47	Front door switch LH	B8	2
      	48	Sliding door switch	B116
      		Back door switch lower LH	D407	1
      		Back door switch lower RH	D607
      		Secondary sliding door switch	D301

   4. Check continuity between BCM and ground.

      BCM		--	Continuity
      Connector	Terminal
      M18	12	Ground	No
      	13
      M19	47
      	48

   Is the inspection result normal?

   YES

   GO TO 3.

   NO

   Repair or replace harness.

3. CHECK DOOR SWITCHES AND GROUND CIRCUIT 
   1. Connect door switch harness connectors.
   2. With suspect door open (switch in closed position) and all other doors in the closed position (switches in open position), check continuity between BCM connector and ground for suspected door. Close suspect door and insure continuity to ground switches relative to door open/close status.

      BCM			--	Continuity
      Connector	Terminal	Item
      M18	12	Front door switch RH	Ground	Yes No
      	13	Back door switch upper RH
      M19	47	Front door switch LH
      	48	Sliding door switch
      		Back door switch lower LH
      		Back door switch lower RH
      		Secondary sliding door switch

   Is the inspection result normal?

   YES

   Replace BCM. Refer to Removal and Installation .

   NO

   GO TO 4.

4. CHECK DOOR SWITCHES 
   1. Disconnect door switch harness connectors.
   2. Check continuity between door switch terminals while cycling suspect switch open to closed.

      Door switch		Continuity
      Item	Terminals
      Front door switch LH	2 - Switch body	Yes No
      Front door switch RH
      Sliding door switch
      Back door switch upper RH	2 - 1
      Back door switch lower LH
      Back door switch lower RH
      Secondary sliding door switch

   Is the inspection result normal?

   YES

   Repair or replace harness or ground.

   NO

   Replace door switch. Refer to Removal and Installation .
