The check engine light came on, I'd like to pull the code and figure out what the issue is. I have a nice laptop, don't want to lay down hundreds of $$$ for a code reader with its own processor when I've got one right here. I looked online and there are hundreds of USB / Bluetooth options for plugging the laptop into the van - any recommendations? And what software (cheap / free) goes best with it? I don't mind googling codes, the main objective is to find out what's happening in there, maybe get some data to play with, and not pay too much. There are a few similar threads on the site but the ones I found are all a few years old. My laptop runs Win 8 or linux (ability to script things with bash would be fun but not that important).
