Door Lock/Unlock

Lock
When the LOCK button is pressed on the transmitter and the Remote Control Door Lock Receiver receives a signal with a valid Vehicle Access Code (VAC). the lock function sequence is performed. The Remote Control Door Lock Receiver will lock all doors.

The Remote Control Door Lock Receiver supplies battery voltage from Connector C1 Terminal D to the coil of the Lock Relay (part of the Door Lock Relay) through the LT BLU (195) wire. The Lock Relay is energized. and battery voltage is supplied to the Door Lock Motors. Ground for the LH Door Lock Motor is provided at the Remote Control Door Lock Receiver Connector C1 terminal D through internal contacts. Ground for the other door lock actuators is provided through the contacts of the UNLOCK Relay contacts of the Door Lock Relay. All door lock actuators energize to lock all doors.

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 front door is unlocked. If the UNLOCK button is pressed twice within one to five seconds. the other doors will be unlocked.

When the UNLOCK button is pressed once on the transmitter and the Remote Control Door Lock Receiver receives a valid VAC, the unlock function sequence is performed. The Remote Control Door Lock Receiver supplies battery voltage to the LH Front Side Door Lock Actuator through the TAN (.694) wire. The actuator is grounded through the contacts of the Lock Relay contacts in the Door Lock Relay. The LH Front Side Door Lock Actuator energizes to unlock the LH front door.

If the UNLOCK button on the transmitter is pressed twice to unlock all doors, the Remote Control Door Lock Receiver activates the door unlock output at Connector C1 terminal E. The Remote Control Door Lock Receiver supplies 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 the RH Front, LH Rear and RH Rear Side Door Lock Actuators. The actuators are grounded through contacts of the Lock Switch in the Door Lock Relay. The actuators energize to unlock the RH Front, LH Rear and RH Rear doors.
