Passenger Select Unlock Relay Circuit Check (With Intelligent Key)

WARNING: This page is about a different car, the 2007 Nissan Versa. However, it is still accessible from the selected car via links, so may be relevant.

CHECK PASSENGER SELECT UNLOCK RELAY CIRCUIT
NOTE: Passenger select unlock relay must remain connected during this step.
1. Turn ignition switch OFF.
2. Disconnect BCM and inoperative rear door lock actuator.
3. Check continuity between BCM connector (A) M20 terminal 65 and rear door lock actuator LH connector (B) D205 terminal 3 or rear door lock actuator RH connector (C) D305 Terminal 3.
  65 - 3: Continuity should exist.
4. Check continuity between BCM connector M20 terminal 65 and body ground.
  65 - Ground: Continuity should not exist.
OK or NG

OK >> GO TO 4.

NG >> GO TO 2.
