Passenger Select Unlock Relay

PASSENGER SELECT UNLOCK RELAY





Description
Controls the operation of both rear door lock actuators.




Component Function Check
1.CHECK FUNCTION
1. Ensure "SELECTIVE UNLOCK FUNCTION" in WORK SUPPORT is enabled.
2. Use CONSULT-III to perform Active Test "DOOR LOCK".
3. Touch "ALL LOCK" or "ALL UNLOCK" to check that both rear doors work normally.
Is the inspection result normal?
YES - Passenger select unlock relay is OK.
NO - SEE Component Function Check.




Diagnosis Procedure
Regarding Wiring Diagram information, With Intelligent Key System.
1.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 66 and rear door lock actuator LH connector (B) D205 terminal 2 or rear door lock actuator RH connector (C) D305 Terminal 2.





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





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 66 and passenger select unlock relay connector (B) M7 terminal 3.





3. Check continuity between BCM connector (A) M20 terminal 66 and body ground.





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. Check continuity between passenger select unlock relay connector (A) M7 terminal 4 and rear door lock actuator LH connector (B) D205 terminal 2 or rear door lock actuator RH connector
(C) D305 terminal 2.





2. Check continuity between passenger select unlock relay connector (A) M7 terminal 4 and ground.





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 2 and 3 or rear door lock actuator connector RH
(B) D305 terminals 2 and 3.










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





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