All Door Unlock

The BCM unlocks all of the doors when you press UNLOCK once on either door lock switch.

Pressing UNLOCK once on either door lock switch sends a ground signal to the BCM through CKT 781.

The ground signal causes the BCM to supply voltage from CKT 1540 to CKT 294 for 315-385 ms.

The voltage energizes all of the passenger door actuators and unlocks all of the passenger doors. At the same time, the BCM grounds CKT 1391 and energizes the door lock relay. The energized door lock relay supplies voltage in CKT 694. The voltage energizes the driver door lock actuator and unlocks the driver door lock.
