Driver Door Module (DDM)


Principles of Operation

The Driver Door Module (DDM) monitors all of the hardwired door ajar switches. This door ajar information is provided to the Instrument Cluster (IC) using the Standard Corporate Protocol (SCP) network. The IC acts as a gateway to translate the information and sends it to the Vehicle Dynamics Module (VDM), if equipped, using the High Speed Controller Area Network (HS-CAN). Diagnostic information is also retrieved from the DDM on the SCP network.

The power door locks and the Remote Keyless Entry (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.
