Can Programmers affect brake controllers?

[DGEM]

I am relativley new to the site and am curious about my new edge evo II tuner. Yesterday I was towing my 18,500# 5th wheel and I changed power levels at a rest stop. When I resumed my trip I had no trailer brakes. My controller indicated that I was not connected at all (I was, my trailer lights were all on). I turned the truck off and restarted it and no change at all. I then unplugged and re-plugged the 5th wheel cord to the truck. As a fluke last resort I unplugged the clip to the safety brake on the trailer and it "re-connected" me to the 5th wheel and I had my brakes back. Does anyone have any idea what caused this? Here is what I have:

2001 F350 7.3
Edge Evo II
Reese Brake Controller set at 7
2002 Travel Supreme 40' 5th Wheel

Thank you and this is an awesome site!

Welcome to the site. i dont know if that would cause it, but maybe by swapping power levels in the programmer it created an electrical fault in the controller to make it think it was disconnected and by pulling the clip it did a hard reset or something. i dont know much about the brake controllers but this sounds possible to me.

Thanks for the input and that definitely sounds like a possibility. Anyone else have any ideas?
