Door Modules: Notes
WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
A multiplexed door module is located on each front door. These are Driver Door Module (DDM) and Passenger Door Module (PDM). They control the following features: power door locks, automatic (rolling) door locks, driver window express down, memory recall functions (adjustable pedals, memory seats and mirrors), remote keyless entry, power mirrors, heated mirrors, door key cylinder disarm (driver door only), door lock inhibit and auto unlock on exit.
Reduced wiring complexity is a key advantage of using multiplexed (MUX) door modules. These modules are addressable with the DRBIII(R) from the Body menu to facilitate faster and easier diagnosis.
