Unlock Operation

The unlock function is separated into two operations depending on how the UNLOCK button is pressed on the keyless entry transmitter.
^ When the UNLOCK button is pressed once only the driver's side door lock is unlocked.
^ When the UNLOCK button is pressed again within five seconds all doors will be unlocked.

When the UNLOCK button is pressed once on the keyless entry transmitter and the Remote Control Door Lock Receiver (RCDLR) receives a signal with a valid Vehicle Access Code (VAC), the unlock function sequence is performed. The RCDLR will supply voltage to the driver's door lock actuator through circuit 694. The actuator is grounded through the contacts of the door lock relay in the door lock relay. The driver's door lock actuator runs to unlock the driver's side door.

If the UNLOCK button on the transmitter is pressed twice to unlock all doors, the RCDLR will activate the door unlock output at circuit 194. The RCDLR will then supply voltage to the coil of the unlock relay in the door lock relay. The unlock relay is energized and closes its contacts. Voltage is supplied to all door lock actuators except the driver's side door. The actuators are grounded through the contacts of the door lock relay. The actuators run to unlock the doors.
