All Door Unlock

The Body Control Module (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.
