Good morning.
I installed a speeduino on my clio 2 rs. with an STM32 controller by pazi88.

but the can bus does not want to work.
I tested with a universal diagnostic tool and an ELM327 but no information was transmitted to my obd2 port.

I don't know if this is due to an error on my part, a bad setting in tunerstudio or a hardware default.

if anyone has any idea what my problem is.

THANKS.


ps: sorry if my English is bad, I am French

You have termination resistors in place?

I placed a 120 ohm resistor on the speeduino side between the Can H and Can L wires.

On the OBD2 port I measured the resistance between the Can H and Can L pin. I have 60 ohm like the original system
