Driver Door Module (DDM)

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The DDM monitors the inputs and provides outputs and diagnostic information for the following multiple vehicle systems, including the:

Power door locks
Remote keyless entry (RKE) system

The DDM monitors all of the door ajar switches as they are hardwired to the module. This door ajar information is sent through the standard corporate protocol (SCP) network to the instrument cluster (IC), which sends the door ajar information to the vehicle dynamics module (VDM) on the high speed controller area network (HS-CAN). Diagnostic information is retrieved from the DDM on the standard corporate protocol (SCP) communication network. The power door locks and the RKE system are all controlled by the DDM. The DDM also receives an input from the luggage compartment lid release switch and operates the luggage compartment lid release solenoid unless the vehicle is equipped with a power luggage compartment lid. In this case, the DDM sends a signal to the luggage compartment lid module, which will operate the luggage compartment lid release solenoid.
