Power Door Dead Lock Operation
Vehicles equipped with the dead lock feature include an additional reversible dead lock motor contained within each door latch assembly. Each door latch assembly is wired to the body control module through 2 control circuits; the door lock dead lock control circuit and the door lock actuator unlock control circuit. To disable the interior door handles, the door locks are activated by momentarily applying voltage to the door lock dead lock control circuits, and ground to the door lock actuator unlock control circuits. Ground to the dead lock actuators is provided through the door lock actuator unlock control circuits. Once the doors are locked with dead lock, the mechanical lock/unlock linkage within the door lock actuator is physically disconnected so that the door cannot be opened by using the interior door handles. If the content theft feature is armed at the same time, the interior door lock switches will not operate the locks.
