Passenger Select Unlock Relay

PASSENGER SELECT UNLOCK RELAY

Description

Controls the operation of both rear door lock actuators, back door latch and glass hatch lock actuators.


Component Function Check


1. CHECK FUNCTION

1.Ensure "SELECTIVE UNLOCK FUNCTION" in WORK SUPPORT is enabled.
2.Use CONSULT to perform Active Test "DOOR LOCK".
3.Touch "ALL LOCK" or "ALL UNLOCK" to check that both rear doors, back door latch and glass hatch lock actuators work normally.
Is the inspection result normal?
YES- Passenger select unlock relay is OK.
NO- .


Diagnosis Procedure

Regarding Wiring Diagram information, With Intelligent Key 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.

65 - 2: Continuity should exist.
65 - 4: Continuity should exist.

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.

4 - 2: Continuity should exist.
4 - 4: Continuity should exist.

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.
