DTC's undefined codes - WHAT THE HECK!

I recently purchased a Bully Dog programer and upon checking the DTC's I have 2 codes:
1) P1000 - WHICH IS SOME KIND DIAGNOSTIC MORE DRIVING REQUIRED CODE.
2) U2205 - THIS IS THE BIG MYSTERY - THE CODE BOOK I HAVE DOES NOT HAVE THIS CODE IN IT SO I CALLED THE FORD HOUSE AND THEY SAID IT IS A UNDEFINED CODE - WHAT THE HECK DOES THAT MEAN?
My check engine light pretty much stays on these days (used to have a Quadzilla chip of which I blamed the light on - now that I have upgraded to the Bully Dog I thought it would clear the reoccuring light but it has not.

Any help would be greatly appriciated!!!

P1000 is just a generic code when the PCM has been messed with like with a chip

U codes are network communication codes. THey only appear when there is a module or wiring problem that prevents communication between modules..

So what can I do to clear these codes? I have tried with my Bully Dog and they come right back!

it could be related to the bullydog...or the problem could need to be fixed to clear it. The p1000 will only go away when the pcm is happy with the amount of drive cycles the truck has gone through and its absolutely nothing to worry about. You even get this code when you disconnect battery cables. The U code....u could try disconnecting the battery cables.....try taking the bully dog out of it...and if that doesnt fix it, then the problem needs to be figured out...

Thanks for the help - I guess by "try taking the bully dog out of it" you mean program back to stock? Should I do this and also disconnect the battery drive for a while? I am pretty new to all this so I really do appriciate the input!
