It's great you can check many codes on the climate control, (http://www.youtube.com/watch?v=gU6aiySTHpU), but which codes are really important to watch out for? Is anybody using this cool feature on regular basis? If any specific codes should better be checked, let me know. I want to know which codes, at what timing (idle, full throttle, etc), and the acceptable value range.
