The instrument cluster locks or unlocks the doors when an actuation input signal from a door lock switch or Memory Mirror Module is received. The instrument cluster turns on the output drivers and provides a voltage level to the door lock motor for a specified time. All passenger doors can be locked or unlocked using a mechanical button mounted on the door trim panel. The drivers door can be locked or unlocked by using the key cylinder.
