airbag problem help, radio, ect. not working

Ever since I bought this truck maybe 4500 miles ago (3 months or so) I have had the airbag light come and go with the code B1650/32 =occupant classification system malfunction
And it disables my radio, keyless entry, and inside lights.
I believe it is a short in the center airbag sensor assembly.
Has anyone else had this same problem and is it common for it to short/go bad?
I acquired the alldata diaggnostc prossedure and to test the assembly I have replace it and see if that fixes the problem.

Any and all help would be greatly appreciate.
P.S. I just replaced all my speakers and would like to use them when I want not when the truck wants, and this hard been going on since before I replaced the speakers so its not from that.
