Door module
no, different.
Principles of Operation
Note: Upon installation of a new driver door module (DDM), the module must be reconfigured. Refer to Section 418-01 . The 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.

Principles of Operation
The driver seat module (DSM) is connected on the standard corporate protocol (SCP) communication network. The DSM controls the driver power seat and communicates with the driver door module (DDM) to control the driver seat memory and both outside memory mirror functions.

Principles of Operation
The lighting control module (LCM) is a microprocessor based module that controls several vehicle subsystems. The LCM responds to electrical input signals from various switches, sensors, and external modules. The LCM is located under the LH side of the instrument panel. Subsystem functions of the LCM include headlamps with autolamps, turn signal lamps/hazard flasher lamps, cornering lamps, parking lamps, daytime running lamps (DRL), courtesy lamps, demand lamps, battery saver and control backlighting. The LCM interfaces with the driver door module (DDM) through the standard corporate protocol (SCP) communication network for the illuminated entry feature.

Principles of Operation
The air suspension module is linked to its own data link connector (DLC). The air suspension module controls the air suspension and the variable assist power steering VAPS. For additional air suspension system information, refer to Section 204-05 .
The air suspension module is used to monitor and control the VAPS system. The VAPS system controls the level of power assistance available to the driver based on vehicle speed and rate of change in steering position. For additional VAPS system information, refer to Section 211-00 .
