CAN Bus Protocol for Mercedes-Benz Atego 2003

Hello everyone,

zur Zeit mache ich eine Diplomarbeit im Bereich Dual Fuel mit einem Mercedes Benz Atego Baujahr 2003.

Initially, I didn't realize that this vehicle had a cruise control system. So far, the dual-fuel system has been working without the cruise control. The cruise control is then manually activated, and when it's engaged, my control unit only receives information from the CAN bus.

I have also been able to retrieve CAN data using CANPeak, and then I receive data like the following example:
Identifier: 8 bytes of data.
200h 10 20 30 30 AF B4 FF 00
3B4h 23 EF D§ F4 78 00 FF 20

Hat jemand vielleicht Ahnung, wie man diese Daten entschlüsseln kann?
Thank you in advance.

Best regards,

How? Yes, according to the WPW principle hehe.

WPW = Was passiert wenn.....

If you have the identifier, you already know a little bit. Then, try connecting, driving, or stopping (you'll have to experiment), and see what happens when you turn on the Tempomat (cruise control) or activate it, etc. Which data changes how ?

which data can decipher this? little problem
