I am a manager at Autozone in UT. We read the codes, but there has been some major uproar of that. we used to be able to clear them and stuff, but now we aren't allowed...some lawsuit...whatever, but I also worked at a shop and understand it from a mechanic's point of view...most of them have spent some serious money on their machines and need to recoop that costs... ie. Snap on machines...a couple grand I'm sure. So it wouldn't surprise me if that happened in CA.
