Driver Door Module (DDM)

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 to the air suspension module on a single hardwired circuit. 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 which case the DDM sends a signal to the luggage compartment lid module, which will operate the luggage compartment lid release solenoid.
