Overall network, general • Comfort

The requirements placed on vehicle electronics, e.g. in the following • Communication
areas, increase continuously:
• Diagnosis
• Vehicle safety
© Mercedes-Benz AG, printed: 2025-01-31, P/01/25, , GF00.19-P-0001RF 5/9
This requires networking of the existing systems in the vehicle so that • CAN
the necessary information can be exchanged.
• Chassis FlexRay
This cannot be achieved using conventional data transfer since the
• MOST
amount of installation space is limited and a reduction of the weight of
the vehicle is targeted. This is why bus systems are used. • Ethernet
The vehicle electronics are networked using the following bus systems:
---------------------------------------------------------------------------
CAN • Telematics CAN
The CAN is an electrical bus system for the transmission of data via two • AMG CAN (model 205 with code 466 (Active engine mount),
lines. The CAN consists of a twisted two-core data line that connects all model 205, 253 with code 467 (Electronic locking differential))
CAN participants (control units) via a parallel connection. The two lines
• Interior CAN
of the data line must not be swapped (low level, high level). Each
connected control unit is able to transmit or receive data (bidirectional • Engine CAN
bus). The data is sent digitally via the CAN at various intervals. The
• Drive train CAN
individual data blocks are defined in a data protocol and it is specified
which data are received or transmitted by a control unit. The sum of the • Diagnostic CAN
data blocks, the short break between two transmission intervals and
• Vehicle dynamics CAN
other properties of the CAN are checked constantly. Detected faults are
stored and placed in the fault memory. • User interface CAN
The CAN offers the following advantages: • Drive train sensor CAN
• Data exchange between individual control units • Hybrid CAN (model 205.012/047/147/212/247, 253.354/954)
• Provision of sensor signals for several systems • Peripherals CAN
• Reduction of the number of electric lines • Radar-CAN 1 (with code 23P (Driving Assistance package))
