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.
