PASSENGER SELECT UNLOCK RELAY


Diagnosis Procedure

Regarding Wiring Diagram information, Power Door Lock System.
1.CHECK PASSENGER SELECT UNLOCK RELAY CIRCUIT

NOTE:
The passenger select unlock relay must remain connected during this step.
1. Turn ignition switch OFF.
2. Disconnect BCM and inoperative back or rear door lock actuator.





3. Check continuity between BCM connector (A) M20 terminal 65 and rear door lock actuator LH connector (B) D205 terminal 2 or rear door lock actuator RH connector (B) D305 Terminal 2 or glass hatch lock actuator (C) D508 terminal 4.






4. Check continuity between BCM connector M20 terminals 66 and body ground.

65 - Ground : Continuity should not exist.

Is the inspection result normal?
YES - GO TO 4
NO - GO TO 2
2.CHECK PASSENGER SELECT UNLOCK RELAY INPUT
1. Disconnect passenger select unlock relay.





2. Check continuity between BCM connector (A) M20 terminal 65 and passenger select unlock relay connector (B) M11 terminal 3.

65 - 3 : Continuity should exist.

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

65 - Ground : Continuity should not exist.

Is the inspection result normal?
YES - GO TO 3
NO - Repair or replace harness between BCM and relay.
3.CHECK PASSENGER SELECT UNLOCK RELAY OUTPUT
1. Disconnect inoperative rear door or glass hatch lock actuator.





2. Check continuity between passenger select unlock relay connector (A) M11 terminal 4 and rear door lock actuator LH connector (B) D205 terminal 2 or rear door lock actuator RH connector (B) D305 terminal 2 or glass hatch lock actuator connector (C) D508 terminal 4.






3. Check continuity between passenger select unlock relay connector (A) M11 terminal 4 and ground.

4 - Ground : Continuity should not exist.

Is the inspection result normal?
YES - Replace passenger select unlock relay.
NO - Repair or replace harness between relay and actuator.
4.CHECK REAR DOOR LOCK ACTUATOR ASSEMBLY
1. Reconnect BCM.





2. Check voltage between rear door lock actuator connector LH (A)
D205 terminals 1 and 2 or rear door lock actuator connector RH
(A) D305 terminals 1 and 2 or glass hatch lock actuator (B)
D508 terminals 2 and 4.










3. Check voltage between rear door lock actuator connector LH (A)
D205 terminals 1 and 2 or rear door lock actuator connector RH
(A) D305 terminals 1 and 2 or glass hatch lock actuator (B)
D508 terminals 2 and 4.






Is the inspection result normal?
YES - Replace rear or glass hatch lock actuator.
NO - Repair or replace harness between actuator and splice.
