5 Series E60 M5 (S85) SAL
Brief description of components
The following components supply an input signal for the power windows function:
-
Switch block in driver's door
>up to 09/2005
All the power windows can be operated via the switch block in the driver's door. The switch block is connected
via a LIN bus on the driver's door module TMFA (LIN = Local Interconnect Network).
>from 09/2005
The switch block is also connected to the body gateway module (KGM) via the LIN bus.

-
Power window switch in front-passenger door, power window switch in rear doors
The passenger door and the rear doors (not on the E63, E64) are each equipped with their own power window
switch.
-
Door contacts of all doors
The door contacts are analysed to detect the status of the doors (OPEN or CLOSED). In the event of a faulty
door contact, a closed door is assumed.
-
Hall sensors in power window motors
Two Hall sensors are integrated in the power window motor (not E63 or E64). The direction of rotation, speed
and position can be determined through these.
The following control units are involved in the operation of the power windows:
-
CAS: Car Access System
The CAS control unit is the master control unit for the functioning of the power windows.
The commands are transmitted via the K-CAN.
-
SGM: Safety and gateway module
>up to 09/2005
The safety and gateway module (SGM) forms the gateway between K-CAN and byteflight.
-
TMFA and TMBF: Driver's door module and front-passenger door module
>up to 09/2005
The door modules are a component of the passive safety system ASE (= Advanced Safety Electronics). The
door modules (TMFA and TMBF) actuate the power windows in the front doors.

-
KGM: Body gateway module
>from 09/2005
The door modules and byteflight have been discontinued. The body gateway module (KGM) actuates the power
windows in the front doors. Moreover, the KGM is the central gateway in the bus system.

-
KBM: Body basic module
The body basic module (KBM) controls the power windows in the rear doors (not on the E63). The body basic
module is linked to the safety and gateway module (SGM) and to the CAS control unit by means of the K-CAN.
[more ...]
The following actuators are controlled for the operation of the power windows:
-
Power window motors
There is a DC motor in each door which drives the power windows.
