DOOR SW-AS : ON

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

OK or NG

OK: Door switch circuit is OK.

NG: GO TO 2.

CHECK DOOR SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect door switch and BCM.
3. 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 BCM connectors (A) M18, M19 terminals 12, 13, 43, 47 and 48.
  2 - 12 : Continuity should exist.
  
  2 - 13 : Continuity should exist.
  
  2 - 47 : Continuity should exist.
  
  2 - 48 : 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.
  
  OK or NG
OK: GO TO 3.

NG: Repair or replace harness.

CHECK DOOR SWITCHES
FRONT AND REAR DOORS

Check continuity between front or rear door switch terminal 2 and exposed metal of switch while pressing and releasing switch.

Door switch is released : Continuity should exist.

Door switch is pushed : Continuity should not exist.

BACK DOOR

Check continuity between back door latch connector (A) D503 terminals 7 and 8 while pressing (closing back door) and releasing (opening back door) switch.

When back door is open : Continuity should exist.

When back door is closed : Continuity should not exist.

OK or NG

OK: (Front and rear doors) Switch circuit is OK.

OK: (Back door) GO TO 4.

NG: Replace door switch.

CHECK BACK DOOR SWITCH GROUND
Check continuity between back door latch connector terminal 8 and ground.

8 - Ground : Continuity should exist.

OK or NG

OK: Back door switch circuit is OK.

NG: Repair or replace harness.
