Hi!

I have been playing with CAN buses for a while now and just got my hands on a FIAT 500 Nuova 500C 1.2 MPi Cabriolet S&S 69 cv.

Last car I played with was a 2013 Volkswagen Polo, and I was able to query rpm, speed, and stuff like this using the 11bits CAN @ 500kbps using this (wikipedia -> OBD-II_PIDs#CAN_.2811-bit.29_bus_format) kind of queries and PIDs. The bus was silent and I would only get my requests and the car's responses on my candump.

However, on this ~2010 Fiat, the messages are broadcast and seem to use 29 bits CAN. I thus get a whole lot of messages per second and can't really differentiate which message comes from which unit, and my queries seem to be completely discarded.

My questions are: has anybody played with this already ? And if so, which PID would be the standard query one (like 0x7df on 11 bits CAN) ?

Thank you!

(Oh, and I checked that too, but none seem to answer directly: www dot outilsobdfacile dot com/vehicle-list-compatible-obd2/fiat)
