Diagnosis Procedure

Regarding Wiring Diagram information, Without Intelligent Key System.

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 (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 (D) D502 (Back without power back door) terminal 3 or (C) D503 (Back with power back door) terminal 7.






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
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 (D) D502 (Back without power back door) terminal 3 or (C) D503 (Back with power back door) terminal 7 and ground.

2 - Ground:Continuity should not exist
3 - Ground:Continuity should not exist
7 - Ground:Continuity should not exist
Is the inspection result normal?
YES- GO TO 3
NO- Repair or replace harness.

3. CHECK DOOR SWITCHES

- Disconnect door switch harness.
- Check continuity between door switch connector terminals.










Is the inspection result normal?
YES- Door switch circuit is OK.
NO- (Front and rear doors) Replace door switch.
NO- (Back door) GO TO 4

4. CHECK BACK DOOR SWITCH CIRCUIT

- Check continuity between door switch connector terminal and ground.










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