OK or NG

OK: Door switch circuit is OK.

NG: GO TO 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) or D512 (Back) terminal 1 and BCM connector (A) M18, M20 terminals 12, 13, 58, 62 and 63.
  1 - 12: Continuity should exist.
  
  1 - 13: Continuity should exist.
  
  1 - 58: Continuity should exist.
  
  1 - 62: Continuity should exist.
  
  1 - 63: Continuity should exist.
4. Check continuity between door switch connector (B) B8 (Front LH), B108 (Front RH), B46 (Sliding LH), B135 (Sliding RH) or D512 (Back) terminal 1 and ground.
