This thread is a novel, so I am not going to read back to start and try to find what I am going to ask if you dont mind.
But each compressor requires a software change in the truck. Meaning when the hardware is changed, one must change the software.
1 - With the original issues, was that truck equip with an AMK originally and worked fine until it did not?
2 - Did you ever verify the software was set for AMK?
3 - When switching to the Hitachi, did you change software?
If you never made the software change to the Hitachi and its working, I have to think that is what the software was always set to do the AMK would never work right, it was "out of spec" as far and the computer was concerned.

When you swapped to the Hitachi, you would have had to remove some extra pipe(s). Were any damaged? There is one for sure that would get yanked with the swap, ran over to the outside of the AMK from above it. I can only think that in some way the AMK conversion was done wrong???

Thomas - do you have sensor extension rods installed. If so, it will not raise form bump stops. You have to jack up the front and rear a bit to get the sensors back into readable range. If not, then we need codes.
