   OK or NG 

   OK: Door switches are OK.

   NG: GO TO 2.

2. CHECK DOOR SWITCH CIRCUIT 
   1. Disconnect front door switches and BCM connectors.
   2. Check continuity between front door switch connector B8 (LH) or B108 (RH) terminal 2 and BCM connectors M18, M19 terminals 12, 47.

      Front door switch LH 

      2 - 47: Continuity should exist. 

      Front door switch RH 

      2 - 12: Continuity should exist. 

   3. Check continuity between front door switch LH connector B8 or front door switch RH connector B108 terminal 2 and ground.

      2 - Ground: Continuity should not exist.
