    OK or NG 

    OK: Door switch 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), B46 (Sliding LH), B135 (Sliding RH) terminal 1 or back door latch (door ajar switch) connector (C) D511 terminal 7 and BCM connector (A) M18, M20 terminals 12, 13, 58, 62 and 63

      1 - 62: Continuity should exist. 

      1 - 12: Continuity should exist. 

      1 - 63: Continuity should exist. 

      1 - 13: Continuity should exist. 

      7 - 58: Continuity should exist. 

    4. Check continuity between door switch connector (B) B8 (Front LH), B108 (Front RH), B46 (Sliding LH), B135 (Sliding RH) terminal 1 or back door latch (door ajar switch) connector (C) D511 terminal 7 and ground.

      1 - Ground: Continuity should not exist. 

      7 - Ground: Continuity should not exist. 

    OK or NG 

    OK: GO TO 3.

    NG: Repair or replace harness.

    BACK DOOR 

    Check continuity between back door latch (door ajar switch) connector D511 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 sliding doors) Switch circuit is OK.

    OK: (Back door) GO TO 4.

    NG: Replace door switch.
