05 ultra diagnostics codes

I need a good techy that can decipher my code combination.
I am getting U 1300, U1255, U1016, and U1097 all at the same time. This gives me an amber check engine light that comes on intermittantly for short periods.
Today when I got home after a short ride I got "Bus ER" on my odometer and flashing of 4 ways when I turned thi ignition to check codes. I did finally get the codes retrieved and they are as above.
Suggestions / advice??

Thanks
