KGM: Body gateway module
> E60, E61, E63, E64 from 09/2005
From 09/2005, the vehicle electrical system has been modified. The body gateway module (KGM) supersedes
the SGM.
The KGM is the data interface (= gateway) between the K-CAN and the PT-CAN. (K-CAN = body CAN; PT-CAN
= powertrain CAN.) The diagnosis wire is connected to the KGM.
-
SGM: Safety and gateway module
> E60, E61, E63, E64 up to 09/2005
> E65, E66
The SGM is the data interface (= gateway) between the K-CAN, byteflight and the PT-CAN. (K-CAN = body
CAN; PT-CAN = powertrain CAN.) The diagnosis wire is connected to the SGM.

Adaptive transmission control
As with earlier automatic transmissions, the 6-speed automatic transmissions offer the choice between a comfort
program and a sport program.
The adaptive transmission control (component of electronic transmission control) adapts the shift characteristics
of the comfort program and sport program to the driver's wish and the driving situation.
In both programs, the adaptive transmission control changes from a basic map to a performance-orientated
map, as required:
•
Comfort program in selector lever position "D"
The comfort program is based on 2 maps: The XE map (extreme economy) and the E map (economy).
The EGS control unit normally selects the economical XE map (= basic map). In case of particular
demands (e.g. load requirements), the system will change to the performance-orientated E map. If the
input signals change in favour of a more gentle driving style, the system will change back to the more
economical XE map.
•
Sport program in selector lever position "M/S"
The sport program effects dynamic, sporty shift characteristics. In the sport program, there is the basic S
SBT 6-speed automatic transmission E53, E60, E61, E63, E64, E65, E66, E70, E81, E83,
