Save yourself the hassle . You can buy a basic reader that will just give you the codes ( no discription ) and erase for 30.00 . that's basically all the codes the key dance is going to give you ,cause it won't give you all of them anyways .for well under 100.00 you can get a good code reader that will read all obdii , manufacturer specific codes , can codes and give you freeze frame data and erase. for 100-150 you can get one that will give you live data , abs codes and do some diagnostics as well .
