Door Lock Operation - Remote Control Door Lock Receiver

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.

Battery voltage is available at cavity R of the Remote Control Door Lock Receiver. This voltage energizes the Door Lock Relay, which in turn, activates the door lock motors. The ground path for the LH Front Door Lock is through the Remote Control Door Lock Receiver cavity A. The RH Front and Side Door Lock Motors ground through the Remote Control Door Lock Receiver cavity H. The Rear Door Lock Motor grounds thorough the Remote Control Door lock Receiver cavity C. The Remote Control Door lock Receiver grounds through G200.
