Centralised 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.
> E60, E61, E63, E64 up to 09/2005
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.
The window lifters for the rear doors are actuated by the body basic module (KBM). The appropriate commands
are delivered on the data buses.
> E70, E81, E87, E90, E91, E92, E93
The power windows in the doors are actuated by the junction box electronics (JBE) and by the footwell module
(FRM).
Centralised control for CA (Comfort Access)
With Comfort Access, an ID transmitter is needed instead of the usual remote control.
The ID transmitter also performs standard remote control functions.
Comfort Access can be used to carry out the following functions:
•
Passive Entry
Opening the vehicle or luggage compartment without actively using the ID transmitter
•
Passive Go
Engine start without actively using the ID transmitter
•
Passive Exit
Closing the vehicle without actively using the ID transmitter
The CAS control unit is the master control unit for all functions carried out via Comfort Access. Vehicles with
Comfort Access are fitted with a CA control unit.
Waking of the MOST via the K CAN for a telematics service
The telephone control unit wakes up cyclically in order to check for receipt of a new request from the telematics
(e.g. an SMS text message to switch on the auxiliary heating).
The MOST network is a closed ring only. For it to work, all bus participants in the MOST network must be
"awake".
As a control unit in the MOST network, the telephone control unit is not able to wake the MOST.
The CAS sends the trigger signal from the telephone control unit via the K-CAN to wake the multi-audio system
controller (M-ASK). The M-ASK then wakes the MOST. Only now can the telephone control unit check whether a
telematics service needs to be executed.
Centralised data source for the vehicle order and redundant data storage for vehicle data
The vehicle order is stored in the CAS. The vehicle order describes the vehicle model, the national version and
