Description & Operation: Lock

When the LOCK button is pressed on the transmitter and the Keyless Entry Module receives a signal with a valid Vehicle Access Code (VAC), the lock function sequence is performed. The Keyless Entry Module will lock all doors.

The Keyless Entry Module supplies battery voltage from terminal F to the coil of the Lock Relay (part of the Door Lock Relay Assembly) through the LT BLU wire. See WIRING DIAGRAMS  . The Lock Relay is energized, and battery voltage is supplied to the Door Lock Motors. Ground for the left hand Door Lock Module is provided at the Keyless Entry Module terminal B through internal contacts. Ground for the other door lock motors is provided through the contacts of the UNLOCK Switch, inside the Door Lock Relay Assembly. All door lock motors run to lock all doors.
