Well, it's OBD II, but typo is no big deal. As for checking codes, 2 options. 1 is go to places like Discount Auto, Autozone, etc, and have them use the scanner. It's free and takes about 2-5 minutes. The other option is bring them up via the DIC. Your little message board in your gauge cluster. To do this, press and hold I THINK, the passenger heater up, and the AC OFF buttons. Should hold for about 5 seconds. It may be the passenger heat and the AC button, I don't recall 100%. Someone else on the board may know for sure, or it may even be in your manual. Best 2 ways I know.
