DTC Diagnosis Procedure

Detects door open/close condition.

1. CHECK DOOR SWITCHES INPUT SIGNAL 

   With CONSULT

   Check door switches (DOOR SW-DR, DOOR SW-AS) in DATA MONITOR mode in BCM with CONSULT.

   • When doors are open:

     DOOR SW-DR (Front door LH)	:ON
     DOOR SW-AS (Front door RH)	:ON

   • When doors are closed:

     DOOR SW-DR (Front door LH)	:OFF
     DOOR SW-AS (Front door RH)	:OFF

   Without CONSULT

   Close all doors. Check suspect door switch circuit voltage between BCM connector M18 or M19 terminals 12, 47 and ground. Cycle suspect door open and closed while monitoring voltage.

   Connector	Item	Terminals		Condition	Voltage (V) (approx.)
   		(+)	(-)
   M19	Front door switch LH	47	Ground	Open Closed	0 Battery voltage
   M18	Front door switch RH	12

   Is the inspection result normal?

   YES

   Refer to Intermittent Incident .

   NO

   GO TO 2.

2. CHECK DOOR SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect suspect door switch and BCM.
   3. Check continuity between suspect door switch and BCM.

      Item	Connector	Terminal	Item	Connector	Terminal	Continuity
      BCM	M18	12	Front door switch RH	B108	2	Yes
      	M19	47	Front door switch LH	B8

   4. Check continuity between BCM and ground.

      Item	Connector	Terminal	--	Continuity
      BCM	M18	12	Ground	No
      	M19	47

   Is the inspection result normal?

   YES

   GO TO 3.

   NO

   Repair or replace harness.

3. CHECK DOOR SWITCHES AND GROUND CIRCUIT 
   1. Reconnect door switch harness.
   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 to close status.

      Item	Connector	Terminal	Item	--	Continuity
      BCM	M18	12	Front door switch RH	Ground	Yes No
      	M19	47	Front door switch LH

   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.
   2. Check continuity between door switch terminals while cycling suspect switch open to closed.

      Item	Terminals	Continuity
      Front door switch LH	2 - Switch body	Yes No
      Front door switch RH

   Is the inspection result normal?

   YES

   Repair or replace harness or ground.

   NO

   Replace door switch. Refer to Removal and Installation .
