DOOR SW-RL :ON
DOOR SW-RR :ON
BACK DOOR SW :ON
- When doors are closed:
DOOR SW-DR :OFF
DOOR SW-AS :OFF
DOOR SW-RL :OFF
DOOR SW-RR :OFF
BACK DOOR SW :OFF
Without CONSULT-III
Check voltage between BCM connector M18 or M19 terminals 12, 13, 43, 47, 48 and ground.
Is the inspection result normal?
YES - Door switch circuit is OK.
NO - GO TO 2
2.CHECK DOOR SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect door switch and BCM.
3. Check continuity between BCM connector (A) M18, M19 terminals 12, 13, 43, 47, 48 and door switch connector (B) B8 (Front LH), B108 (Front RH), B18 (Rear LH), B116 (Rear RH) terminal 2 or back door latch connector (C) D503 terminal 7.

2 - 13 :Continuity should exist
7 - 43 :Continuity should exist
4. Check continuity between door switch connector (B) B8 (Front
LH), B108 (Front RH), B18 (Rear LH), B116 (Rear RH) terminal
2 or back door latch connector (C) D503 terminal 7 and ground.
2 - Ground :Continuity should not exist
7 - Ground :Continuity should not exist
Is the inspection result normal?
