Door Lock Control Switches
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The door lock control switches are double pole, single throw switches. The DDM and PDM provide the voltage signal to the corresponding door lock control switch for the lock and unlock requests. When a switch is pressed to lock or unlock, the corresponding input circuit is routed to ground, indicating a request to lock or unlock the doors.
