All Door Unlock

The Unlock function is separated into two operations depending on how the "UNLOCK" Button is pressed on the Transmitter. If the "UNLOCK" Button is pressed once, only the LH Door is unlocked. If the "UNLOCK" Button is pressed twice within 1 to 5 seconds, all doors will be unlocked.

When the Unlock Button is pressed once on the Transmitter and the RCDLR receives a signal with a valid Vehicle Access Code (VAC), the Unlock function sequence is performed. The Remote Control Door Lock Receiver (RCDLR) will supply battery voltage to the LH Door Lock Actuator via CKT 694. The actuator is grounded through the contacts of the Lock Relay in the Door Lock Relay. The LH Door Lock Actuator runs to unlock the LH Door.

If the "UNLOCK" Button on the Transmitter is pressed twice to unlock all doors, the RCDLR will activate the Door Unlock output at CKT 694. The RCDLR will then supply battery voltage to the coil of the Unlock Relay in the Door Lock Relay. The Unlock Relay is energized and closes its contacts. Battery voltage is supplied to all Door Lock Actuators except the LH Front. The Actuators are grounded through the contacts of the Lock Relay in the Door Lock Relay. The Actuators activate and unlock the doors.
