Peugeot 207 CAN-Bus

[Translating...]

Ich möchte einen Arduino mit meines Peugeot 207 CAN-Bus verbinden. Es ist mich noch nicht gelungen, mit Kabeln im Radio oder der ODB2 Stecker.

Hat jemand mit einem 207 dieses schon geschaft? Ich sehe schon Videos auf Youtube, aber keine Guides wie ich das schaffen kann.

(Sorry für mein Deutsch, ich bin Holländisch )

You can take CAN connection from here as well

Thank you, and what data speed should I use?

When I try to connect, the whole system crashes (Multifunction display becomes blank, dials start to move, error lights are coming on).

baudrate i dont remember.. maybe 125kbps.

But you can try also OBD 6 & 14 pins. baudrate 500kbps.

With both connections you shouldn't get any errors on instrument cluster. Or your baudrate was not correct, or you switched high and low wires.

I connected my interface in Peugeot cars (308 was last one) and I did not get any errors.

Thanks. Will try again. What adapter did you use?

I tried this one.

adapter for what?
for reading CAN bus with PC: interfaces from Peak System.
For final applications: my own pcb.

OBD 6 & 14 pins with baudrate 500kbps I'm getting no data, but at least I did not get any errors on the instruments. Also tried 125kbps, but didn't help.

The question is, when was your Peugeot built?
I have connected a lot of French vehicles, all have free access to the CAN at the OBD port pins 6 & 14.

It's a Peugeot 207 from 2008.

I connected on OBD 6 and 14 and like in my picture.

You can try this one as well:

I got it working on ODB pins 6 and 14. I've got another question; does the wire thickness matter for an OBD connection? Can I safely use breadboard-type cable (0.2mm², AWG24)?
