Good post, there, ^^^^, very helpful, and good way to have a quick reference. I do have to say I like the way they have standardized the codes so to speak, which does make them easier to understand.

Nice Job

Thanks for the post. I'm trying to learn how to use the canbus to find some problems in my '06 Ram 3500 5.9L that are driving me crazy, I'm sure this will help in that vane.
