   OK or NG

   1. OK: Door switch circuit is OK.
   2. NG: GO TO 2.
2. CHECK DOOR SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect door switch and combination meter connector.
   3. Check continuity between door switch connector B17 (driver side), B410 (passenger side) terminals 1 and combination meter connector M19 terminals 7, 6.

      Driver side door 

      1 (G/B) - 7 (W): Continuity should exist  .

      Passenger side door 

      1 (P) - 6 (P): Continuity should exist  .
