Hi guys

I want to log the key presses in on my mercedes like steering wheel, window, commander keys etc ...
Need some information on the canbus wiring and OBD-2 port on my 2008 C300.
I tried to find the information on the owners manual but unsuccessful.

I have few questions.
1) There are two canbus on mercedes? CAN-C and CAN-B? what are their operating baudrates?
2) CAN-C is used for engine and CAN-B used for interior communications?
3) Are both CAN-C and CAN-B exposed on the OBD-2 port or only CAN-C?
4) Easiest way to tap into the CAN-B? Hopefully without cutting any wires.

thanks

Hi guys

After some searching. Found some answers.
1) yes and can-c is 500Kbps. Can-b not sure.
2) yes
3) only can-c
4) found this link http://www.carlogic.org/bg/data/MB%20CAN(ICC).pdf which shows the location on w203. might be same for w204

I want to know the part no for plugs that go in the can distribution rail X30 connector, So I can tap onto the can-bus. Check the following pic, the brown and brown-red wires are for can-b.

what is the best way to clean the connectors? Water leak has caused my car not to start anymore

Do not clean them...... Replace them. Make sure you find out why there was water inside your vehicle. If you don't it is going to happen again.
