5 Series E60 525xd (M57T2) SAL
The shift pulse is transmitted electrically to the EGS control unit. With this gearshift method ("shift-by-wire") there
is no mechanical linkage between the gearshift paddles and the transmission.
Pull one of the gearshift paddles briefly to change up a gear.
Press one of the gearshift paddles briefly to change down a gear.

Instrument cluster display
The drive ranges and drive program are displayed in the instrument cluster, the signal required for this is sent
from the electronic transmission control.

CID: Central Information Display
> E60, E61, E63, E64, E70, E81, E85, E86, E87, E90, E91, E92, E93
The CID displays detailed information about the Check-Control messages in the instrument cluster.
The instrument cluster controls these messages on the K-CAN (body CAN).
In addition to the visual display, the Check Control also alerts the driver with acoustic signals. Depending on the
importance of the associated message, a single or double gong with varying volume and tone will sound. The
instrument cluster controls these warnings by means of the K-CAN. Acoustic warnings are emitted by the M-ASK
(multi-audio system controller) or CCC (Car Communication Computer).
-
CD: Control display
> E65, E66
The control display is the central display for the information and communication system.
The control display is used as an interface between the MOST and K-CAN data buses. (MOST = "Media
Oriented System Transport"; K-CAN = body controller area network".)
Amongst other things, detailed information about the Check-Control messages in the instrument cluster are
displayed on the control display.
The instrument cluster controls these messages on the K-CAN (body CAN).
The electronic transmission control requires signals from the following components (in alphabetical order):
-
Brake light switch
The signal from the brake light switch is needed for the function of the selector lever lock and the adaptive
transmission control.
-
DME or DDE: Digital engine electronics or digital diesel electronics
The DME or DDE sends messages about the current operating status of the engine to the EGS (e.g. engine
speed or torque).
The EGS reports the current operating status of the transmission back to the DME or DDE.
-
DSC: Dynamic Stability Control
The DSC optimises both driving stability when pulling away or accelerating and traction. Within the limitations of
the laws of physics, DSC compensates for driving conditions such as over/understeering. As part of this
process, dynamic driving signals (e.g. wheel rotation speed, lateral acceleration) are sent to the DSC control
unit. DSC transmits the processed signals regarding cornering, acceleration and winter detection to the EGS
control unit.
-
Accelerator pedal module
The signal from the accelerator pedal module is needed for the adaptive transmission control.
-
JBE: Junction box electronics
> E70, E81, E87, E90, E91, E92, E93
The JBE is the data interface (= gateway) between the K-CAN and the PT-CAN. Signals from the F-CAN are
simply looped through. (K-CAN = body CAN; PT-CAN = powertrain CAN; F-CAN = chassis CAN.)
The junction box consists of the JBE and the power distributor.
