5 Series E60 525d (M57TU) SAL
The CAS control unit and M-ASK/CCC receive the converted wheel speed signal from the rear left wheel.
Both these control units use this signal to ascertain whether the car is moving or at a standstill.

SGM: Safety and gateway module
> E60, E61, E63, E64 up to 09/2005
The SGM is the data interface (= gateway) between:
•
PT-CAN
•
K-CAN
•
Byteflight
•
Diagnosis wire to diagnosis socket
-
KGM: Body gateway module
> E60, E61, E63, E64 from 09/2005
The vehicle electrical system was changed from 09/2005. As a result of the change, several control units were
discontinued and some control unit functions were integrated into new control units.
The new body gateway module supersedes the safety and gateway module (SGM) previously fitted.
The KGM is the data interface (= gateway) between:
•
PT-CAN
•
K-CAN
•
Diagnosis wire to diagnosis socket
-
JBE: Junction box electronics
> E90, E91 from 09/2005 and
> E92 from 06/2006
The JBE is the data interface (= gateway) between:
•
PT-CAN
•
K-CAN
•
Diagnosis wire to diagnosis socket
Signals from the chassis CAN (F-CAN) are simply looped through.
-
ACC: Active Cruise Control
DSC receives requests from Active Cruise Control (ACC) via the PT-CAN. In response, DSC reduces speed by
applying the brakes at all four wheels.

>
E90, E91 from 09/2005 and
E92 from 06/2006
The request for brake application is given by the LDM control unit (LDM: longitudinal dynamics
management).

LM: Light module
> E60, E61, E63, E64
As required by law, the brake lights are activated in the event of automatic braking when the Electronically
Controlled Deceleration function (ECD) is triggered by the ACC.
To do this, a signal must be sent from the DSC to the light module (LM) via the K-CAN.
