Passenger Select Unlock Relay Circuit Check (With Intelligent Key)

1. Turn ignition switch OFF.
2. Disconnect BCM and inoperative rear door lock actuator.
3. Check continuity between BCM connector M20 (A) terminal 65 and rear door lock actuator LH connector D202 (B) terminal 2 or rear door lock actuator RH connector D302 (C) Terminal 2.

   65 - 2 : Continuity should exist. 

4. Check continuity between BCM connector M20 (A) terminal 65 and body ground.

   65 - Ground : Continuity should not exist. 

OK or NG 

OK: GO TO  4.

NG: GO TO 2.
