5 Series E60 525d (M57TU) SAL
The crash safety module evaluates the data from the sensors.
In the case of a crash, the crash safety module decides whether it is necessary to trigger the seat belt tensioner
and airbags and what airbags need to be triggered.
The crash safety module also triggers the active head restraints (only E60, E61 and E70 from 09/2007).

CAS: Car access system
The CAS control unit provides input signals relating to terminal voltage (e.g. terminal R ON). The CAS control
unit is the master control unit for the central locking system. (KGM, KBM and JBE are the executing control units
for the central locking.)
-
DME or DDE: Digital engine electronics or digital diesel electronics
When an airbag is triggered, the electric fuel pump is switched off by the DME or DDE (only on vehicles with no
electronic control of the fuel pump).
-
EKP: Controlled fuel pump
When an airbag is triggered, the electric fuel pump is switched off by the EKP control unit (only on vehicles with
electronic control of the fuel pump).
The EKP control unit receives a message from the crash safety module.
-
GM: General module
> E85
The general module provides input signals relating to terminal voltage (e.g. terminal R ON). The general
module is the executing control unit for the central locking system. The general module controls the interior
lighting. In the event of an accident with corresponding severity, the interior light switches on automatically and
the central locking unlocks.
-
KOMBI: Instrument cluster
The instrument cluster provides a visual seat belt warning and triggers an audible seat belt warning.
The crash safety module controls the seat belt warning using a check control message.
The instrument cluster receives data about the status from the crash safety module when terminal R is ON.
Depending on the status, the optical and audible warning is triggered when terminal 15 is ON.
-
KGM: Body gateway module
> E60, E61, E63, E64
The KGM is the data interface (= the gateway) between the K-CAN and the PT-CAN. (K-CAN = body CAN; PT-
CAN = powertrain CAN.)
The KGM is connected to the crash safety module via the K-CAN.
The KGM is the executing control unit for the front central locking system. (The CAS control unit is the master
control unit for the central locking system. )
The KGM controls activation of all front central locking drive units.
In the event of an accident exceeding a certain severity (crash signal from crash safety module) the front central
locking is automatically unlocked.
-
KBM: Basic body module
> E60, E61, E63, E64
The KBM is connected to the crash safety module via the K-CAN.
The KBM is the executing control unit for the rear central locking system. (The CAS control unit is the master
control unit for the central locking system. )
The KBM controls activation of all rear central locking drive units.
