RAC System Fail Code

Has anyone ever heard of this code; "RAC System Fail"? I get this on the dash readout about 5-7 times a week. It is accompanied by a warning beep (same as low air beep) and if it is going to happen, it only has ever happened when it changes to 8th gear - no other gear.

I have called Eaton and six different Freightliner dealerships and they are all puzzled by this saying that they have never heard of it.

I'll be doggone, Jerry, I do believe you are onto something here. This is the closest thing I have seen to answer this problem. I can't believe that out of six Freightliner dealers none of them could come up with anything.

Thank you for your help. Now I will go to my appointment tomorrow and rub this in their faces.
