Peugeot 207 CAN-Bus

I want to connect an Arduino to the CAN-bus of my Peugeot 207. I haven't been successful yet using cables in the radio or the OBD2 connector.

Has anyone managed to do this with a 207? I've seen videos on YouTube, but no guides explaining how to do it.

(Sorry for my German, I am Dutch )

You can take the CAN connection from here as well .

"Vielen Dank, und welche Datenrate sollte ich verwenden?"

**Translation:**

"Thank you, and what data speed should I use?"

When I attempt to connect, the entire system crashes (the multifunction display goes blank, the dials start moving, and error lights illuminate).

"I don't remember the baud rate... maybe 125 kbps."

You can also try using the OBD 6 and 14 pins with a baud rate of 500 kbps.

With either connection, you shouldn't encounter any errors on the instrument cluster. Either your baud rate is incorrect, or you may have swapped the positive and negative wires.

"I've connected my interface to Peugeot cars (the 308 was the most recent), and I haven't encountered any errors."

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

Sure. I'll try again. What adapter did you use?

I've tried that one before.

adapter for what?
For reading the CAN bus using a PC: Interfaces from Peak System.
For final applications: my own custom-designed PCB.

"Thank you, and where did you make the connection in the Peugeot cars?"

OBD 6 & 14 pin connections with a baud rate of 500 kbps are yielding no data. However, at least there were no error messages displayed on the instrument panel. I also tried 125 kbps, but that didn't resolve the issue.

Die Frage ist: Wann wurde Ihr Peugeot hergestellt?
"I've successfully connected to many French vehicles, and they all allow free access to the CAN bus through the OBD port pins 6 and 14."

The question is, when was your Peugeot built?

It's a Peugeot 207 from 2008.

I am getting no data, but at least I did not get any errors on the instruments. } Also tried 125 kbps, but it didn't help.}
I connected to ports 6 and 14, as shown in the picture.

Okay, I'm ready. Please provide the German text you want me to translate into English.

"I managed to get it working using pins 6 and 14 on the ODB connector. I have another question: Does the wire gauge matter for an OBD connection? Can I safely use breadboard-style jumper wires (0.2mm², AWG24)?"
