Soooo I think I messed up Finally got my bypass cable so I can use AlphaOBD to make changes to tire size and TPMS. It's cold so I had the truck running while I'm getting setup and then I made my tire size change with the engine on. Oops! Nowmy dash is lit up like a Christmas tree. I got too excited and should have turned the engine off and turned the key on to accessory. Now what?
