MODULE CONTROLLED FUNCTIONS
The multi-function modules consist of the following:
^ air suspension control module
^ Driver Door Module (DDM)
^ Driver Seat Module (DSM)
^ [1][2]Lighting Control Module (LCM)

The air suspension control module is linked to its own Data Link Connector (DLC). The air suspension control module controls the air suspension and the electronic variable orifice (EVO) steering.

The Driver Door Module (DDM) is connected on the Standard Corporate Protocol (SCP) communication network. The DDM controls many functions including power windows, power door locks and remote keyless entry. The DDM also communicates with the Driver Seat Module (DSM) to control the power mirror and seat memory functions.

The DSM is connected on the SCP communication network. The DSM controls the driver power seat and communicates with the DDM to control the driver seat memory and both outside memory mirror functions.

The Lighting Control Module (LCM) is connected on the SCP communication network. The LCM controls both interior and exterior lighting, back lighting, the battery saver and warning chimes.
