The BCM unlocks all doors when pressing unlock once on either door lock switch.

Pressing unlock on either door lock switch sends a ground signal to the BCM through circuit 781. This action causes the BCM to supply voltage from circuit 1540 to circuit 294 for 350)+/- 35) ms, energizing all passenger door actuators and unlocking all passenger doors. At the same time the BCM grounds circuit 1391, energizing the door lock relay. The door lock relay, when energized, supplies voltage in circuit 694. This action energizes the driver's door lock actuator and unlocks the driver's door lock.

Pressing lock on either door lock switch sends a ground signal to the BCM through circuit 780. When the BCM deems appropriate to lock the doors (based on last door closed locking and lockout prevention features), the BCM applies voltage from circuit 1540 to circuit 295 for 350 (+/- 35) ms, energizing all door actuators and locking all vehicle doors.

The BCM activates the last door closed locking feature when these conditions are met:

Upon pressing lock, the BCM to sound the chime 3 times. This provides feedback indicating that the last door closed locking feature is active. 5 (+/- 0.5) seconds after all doors are closed, the BCM locks all doors.

To cancel this feature:

To override this feature: Press lock twice. The BCM locks all door immediately with a door still open.

The BCM does not lock the vehicle doors when pressing lock on either door lock switch with the lockout prevention feature active. The BCM activates the lockout prevention feature when these conditions are met:

When the lockout prevention feature is active, the BCM disables these automatic door lock features:

To override the lockout prevention feature, press and hold lock on either door lock switch for three seconds. This action causes the BCM to lock all doors immediately.

The BCM unlocks all doors when these conditions are met:

The BCM unlocks the driver's door only when these conditions are met:

The BCM locks the doors when these conditions are met:

Two ways to change the automatic door lock/unlock mode:

Perform the following procedure to change the automatic door lock/unlock mode using the door lock switch method:

1. Close all vehicle doors.
2. Turn the ignition switch on.
3. Step firmly and hold brake pedal.
4. Press and hold lock on either door lock switch. Note: All door lock.
5. While holding lock on the door lock switch, shift the transaxle out PARK. The automatic door lock/unlock mode remains in mode 3, and all doors lock.
6. While still holding lock on the door lock switch, shift the transaxle into PARK. The automatic door lock/unlock mode remains in mode 3, and all doors unlock.
7. While still holding lock on the door lock switch, shift the transaxle out PARK. The automatic door lock/unlock mode changes to mode 4, and all doors lock.
8. While still holding lock on the door lock switch, shift the transaxle into PARK. The automatic door lock/unlock mode remains in mode 4, and only the driver door unlocks.
9. While still holding lock on the door lock switch, shift the transaxle out PARK. The automatic door lock/unlock mode changes to mode 1, and all doors do not lock.
10. While still holding lock on the door lock switch, shift the transaxle into PARK. The automatic door lock/unlock mode remains in mode 1, and doors do not unlock.
11. To advance the mode, shift the transaxle out PARK then back into PARK again while holding the door lock switch in the lock position.
12. A transition past mode 4 repeats the sequence starting with mode 1.
13. To exit and save the current customization mode:

Release the door lock switch when obtaining desired mode.

14. Mode 3 is set when the vehicle was manufactured. Disconnecting the vehicle battery for up to a year will not change the mode.

Two ways to change the delayed locking mode:

Perform this procedure to change the last door closed locking mode using the door lock switch method:

1. Close all vehicle doors.
2. Turn the ignition switch on.
3. Step firmly and hold brake pedal.
4. Press and hold unlock on either door lock switch.
5. While holding unlock on the door lock switch, shift the transaxle out PARK then back into PARK.
6. To change the last door closed locking mode shift the transaxle out PARK then back into PARK again.

•	The BCM sounds the chime once when the last door closed locking mode is disabled and twice when enabled.

•	To exit and save the current customization mode: Release the door lock switch when obtaining desired mode.

•	The last door closed locking mode is enabled when the vehicle was manufactured. Disconnecting the vehicle battery for up to a year will not change the mode.
