Reading the AC codes
I did the set up to see the AC codes and notice I got more number then I should. http://www.idavette.net/tech/c4diag.htm Here the link of the codes. But for some reason when I run through the code I got more codes. 19,20,21,22,23,24. Are the other number normal?

As mentioned above consult your FSM. If you are not satified with your findings: Remove the negative cable on the battery for a few minutes or more then reinstall. Run the AC unit through the various cycles then check for fault codes again to see if they reappear.

Beats me - Fault Codes are in Module 0. All the other stuff is a binary representation of sensor input; temp door position and maybe one or two other things. That's useful only if you think you're getting the wrong output from the input or garbage in garbage out. Why are you looking for fault codes? The most common failure is no gas. After that, the temp door craps out and you don't get heat or you don't get a/c - post the issue.

If there no faults, I wouldn't worry about it OR page through the Modules and write each number down and then compare it to the list which generally gives you the extreme for each device. Getting something in between the extremes would be normal unless there was a problem.

0,1,2,3,4,5,6,7,9,10,11,12,30,31,34,36,3 7
These are the parameter that the book states.
I have these 6 other parameter 19,20,21,22,23,24. I have no clue what they could be or what use they may have.
