  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
