Not sure if this belongs in a different section, however, is it possible to easily access the wheel speed data over the ODBII bus? I've googled a few different terms, but mainly get results about wheel speed sensor faults. Most ODBII readers I have found are fault code readers which isn't what I need.

I just want to be able to access the wheel speed over CAN, do a bit of data reformatting, and output again to another system. I really don't want to have to fit a separate wheel speed sensor for the work I'm doing. I thought about using precision GPS, but that can get noisy at low speeds.

Thanks for the replies. I think a 2Byte message would be useable, 1Byte wouldn't be accurate enough. I've got access to a 2011 Defender, and a 2013 Focus.

Thought I'd made a miracle breakthrough when someone pointed out we have a Kistler sensor. No idea why we have it, but unfortunately it is not road legal.
