If I might ask, what connection hardware are you using to connect to your vehicle (e.g. ELM, Mongoose, etc.), and what network(s) did you find on the vehicle (e.g. J1850VPW, CAN, etc.)?
Hello, I'm working on a small personal project and am trying to find a good listing of GM or more specifically 2006 silverado enhanced PIDs. I have gotten all the standard mode 01 data just fine, but I'd like to get everything out of the computer possible. If I understand this right it's proprietary, but no doubt someone has at least a few of them they've figured out. I will share any that I decode myself but no doubt it'll take a long time to decode them all considering the mode 22-24 stuff is 16 bit and there's 65000+ possibilities
I'm using an ELM 327. And although I believe GM is J1850VPW only, I haven't tried any others.
