Door Switch Check


1. CHECK DOOR SWITCHES INPUT SIGNAL

With CONSULT
Check door switches ("DOOR SW-DR", "DOOR SW-AS", "DOOR SW-RL", "DOOR SW-RR", "BACK DOOR SW") in DATA MONITOR mode with CONSULT. Scan Tool Testing and Procedures .

- When doors are open:
DOOR SW-DR: ON
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

Without CONSUL
Check voltage between BCM connector M18 or M19 terminals 12, 13, 43, 47, 48 and ground.











OK or NG
OK- Door switch circuit is OK.
NG- GO TO 2

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) terminal 2 or (C) B6
(rear LH), B116 (rear RH) terminal 1 or back door lock assembly connector (D) D405 terminal 3 and BCM
connectors (A) M18, M19 terminals 12, 13, 43, 47 and 48.
1 - 13: Continuity should exist.
1 - 48: Continuity should exist.
2 - 12: Continuity should exist.
2 - 47: Continuity should exist.
3 - 43: Continuity should exist.

4.Check continuity between door switch connector (B) B8 (front
LH), B108 (front RH) terminal 2 or (C) B6 (rear LH), B116 (rear
RH) terminal 1 or back door lock assembly connector (D) D405
terminal 3 and ground.

1 - Ground: Continuity should not exist.
2 - Ground: Continuity should not exist.
3 - Ground: Continuity should not exist.
OK or NG
OK- GO TO 3
NG- Repair or replace harness.






3. CHECK DOOR SWITCHES

FRONT AND REAR DOORS
Check continuity between front door switch terminal 2 or rear door switch terminal 1 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 lock assembly connector (back door switch) terminals 3 and 4 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-1- (Front and rear doors) Switch circuit is OK.
OK-2- (Back door) GO TO 4
NG- Replace door switch.






4. CHECK BACK DOOR SWITCH GROUND

Check continuity between back door lock assembly connector D405
terminal 4 and ground.
4 - Ground: Continuity should exist.
OK or NG
OK-1- Back door switch circuit is OK (without Intelligent Key).
OK-2- GO TO 5 (with Intelligent Key).
NG- Repair or replace harness.






5. CHECK BACK DOOR SWITCH SIGNAL FOR SHORT

1.Disconnect Intelligent Key unit.
2.Check continuity between BCM connector M18 terminal 30 and ground.
30 - Ground: Continuity should not exist.





OK or NG
OK- Back door switch circuit is OK.
NG- Repair or replace harness.
