Door Modules: Notes

A multiplexed Driver Door Module (DDM) is located in the driver door. The DDM controls the following features:

• power door locks
• automatic (rolling) door locks
• driver front window and driver rear window, including express down for both
• a window lockout feature for all passenger power windows
• memory recall functions (radio, adjustable pedals, memory seats and driver mirror)
• driver memory mirror
• driver power mirror
• driver heated mirror
• door key cylinder disarm (driver door only)
• door lock inhibit
• switch learning features
• central lock from the key cylinder (driver door only)
• central unlock from the key cylinder and auto unlock on exit (driver door only)

A multiplexed Passenger Door Module (PDM) is located in the front passenger door. The PDM controls the following features:

• power door locks
• passenger front window and passenger rear window, including express down for both
• passenger memory mirror
• passenger power mirror
• passenger heated mirror

Reduced wiring complexity is a key advantage of using multiplexed door modules. These modules are addressable with the DRBIII® from the "Body" menu to facilitate faster and easier diagnosis. In addition, the door nodes offer:

• battery protection
• door lock inhibit - this feature disables the door lock functions if the key is in the ignition and either front door is ajar. Pressing the RKE lock/unlock button under these conditions will result in normal lock/unlock activation.
