So, does anyone know of a good OBD II scanning tool that I can buy? Are they expensive? Maybe you can suggest a good, basic-featured model that is cheaper and a good full-featured model that is more expensive.
Thanks!!

I'm almost certain that On Star will tell you what the code is and what it refers to if you push the little blue button and ask for HELP!
