OK or NG 

OK : Door switch circuit is OK.

NG : GO TO 2.

1. Disconnect door switch and BCM connector.
2. Check continuity between door switch connector B26, B36, B46, B206 terminals 1 and BCM connector M3, B14 terminals 62, 12, 63, 13.

   Driver side door 

   1 (W) -62 (W) : Continuity should exist. 

   Passenger side door 

   1 (SB) - 12 (P/B) : Continuity should exist. 

   Rear door LH 

   1 (P) - 63 (P) : Continuity should exist. 

   Rear door RH 

   1 (P) - 13 (P/L) : Continuity should exist. 

3. Check continuity between door switch connector B26, B36, B46, B206 terminal 1 and ground.

   1 (W, SB, P) - Ground : Continuity should not exist. 

OK or NG 

OK : GO TO 3.

NG : Repair or replace harness.
