Overview

Door control module (in WIS) or Electric Seat Adjuster Switch (in EPC) is ... When looking for part in catalogues, you may need to add 7C45 to end of part number (e.g., A22082106587C45).

The door control module in itself is pretty dumb device. All key presses are sent over CANBUS to SAM. SAM then broadcasts message to all modules and module which understands the message acts appropriately (whether lighting up some bulb, engaging seat heating, moving seat, etc.).

Location

In door panel hold by plastic clips.

Front of door control module trim.
Back of door control module trim.

PICTURE

Using right hand drive DCM in left hand drive vehicle

It has been tested that RHD DCM A2208212179 installed on left side of LHD vehicle originally equipped with A2208214179 will work fine, however, the mirror controlling switch will not work and window controlling switch will be able open only driver's door window. Similarly, RHD DCM A2208211879 installed on left side of LHD vehicle originally equipped with A2208214979 will work fine, however, the window opening switch will open left side driver's door window.

Using left DCM on the right side

The physical location of DCM is programmed into DCM. E.g., if left DCM is connected to right side, the DCM will still move left seat.

Seat ventilation

Seat ventilation functionality does not depend on DCM. Appropriate buttons are not part of DCM and can be bought separately.


Door control module with heating button removed.
Back of heated and ventilated seat button.
A2208210358 -- Heated seat button for left DCMs.
A2208210458 -- Heated seat button for right DCMs.
A2208210558 -- Heated and ventilated seat button for left DCMs.
A2208210658 -- Heated and ventilated seat button for right DCMs.

Upgrading to DCM supporting memory seats

It seems that seat memory function is determined by DCM itself.

It has been tested that vehicle originally equipped with DCM A2208214179 in drivers doors can be replaced with DCM A2208211579 and memory seats will work out of the box. To mount DCM with memory buttons appropriate door panel with holes for memory buttons must be mounted. Alternatively, if memory functionality is not needed, one can replace front control board connected by wire with control board from A2208214179.
