Delay Locking

The power door lock control module, controls the activation of the side door lock actuator. With the side door open, actuation of a door lock switch to the lock position locks the front doors and the rear door immediately. However, the side door lock actuator does not operate, because the contacts at the side door contact plate are open. When the power door lock control module senses an active state on the side door jamb switch signal circuit (side door open) a delay lock function is activated. When the door lock control module senses an inactive state on the side door jamb switch signal circuit (side door closed) the door lock control module starts a timer which, after approximately 5 seconds, produces another lock command. This additional lock command cycles the door lock relay to lock all the doors.

If during the 5 second delay, the side door reopens, the power door lock control module remains enabled. The power door lock control module again waits for closure of the side door. The side door will lock 5 seconds after the side door closes. If, during the timing process, the module receives a command for unlocking all of the doors, both the logic and the timer reset. The side door does not lock, even when the door is already closed.
