Diagnosis Procedure

Regarding Wiring Diagram information, [1][2]Electrical Diagrams.

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.
- 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 CONSULT
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 M18, M19 terminals 12, 13, 43, 47, 48 and door switch connector B8 (Front LH), B108 (Front RH), B18 (Rear LH), B116 (Rear RH) terminal 2 or back door latch connector D502 terminal 3.





2 - 47:Continuity should exist
2 - 12:Continuity should exist
2 - 48:Continuity should exist
2 - 13:Continuity should exist
3 - 43:Continuity should exist
4.Check continuity between door switch connector B8 (Front LH), B108 (Front RH), B18 (Rear LH), B116 (Rear RH) terminal 2 or back door latch connector (C) D502 terminal 3 and ground.
2 - Ground:Continuity should not exist
3 - Ground:Continuity should not exist
Is the inspection result normal?
YES- GO TO 3 (front and rear door).
YES- GO TO 4 (back door).
NO- Repair or replace harness.

3. CHECK FRONT AND REAR DOOR SWITCHES

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










Is the inspection result normal?
YES- Door switch circuit is OK.
NO- Replace door switch.

4. CHECK BACK DOOR SWITCH

Check continuity between door switch terminals.










Is the inspection result normal?
YES- Repair or replace back door switch ground circuit.
NO- Replace back door switch.
