Centralized control of the power windows

The CAS is the master control unit for the power windows.

Because of the various national versions, the functions of the power windows are heavily dependent on the encoding.

The power windows in the front doors are actuated by the door modules (TMFA and TMBF).

The window lifters for the rear doors are actuated by the body basic module (KBM). The appropriate commands are delivered on the data buses.

• E60, E61, E63, E64 from 09/2005

The power windows in the front doors are controlled by the body gateway module (KGM). The door modules and the byteflight  are discontinued.
