More OBD code outputs (P1637-P1643)

There seems to be a lot of OBD code threads around recently, I have another one. I have a persistent code of P1637 and P1643. This generates the "Reduced Performance" message along with "Transmission fault", "Cruse Control Not Available" and "Low Brake Fluid" messages.
The codes are associated with modules not talking to each other and I know the brake fluid is not low so at least some of the other messages are probably artifacts also. Does anyone know of a particular bad ground or connection or other cause I can test before I go to my dealer with the problem?
Thanks for any help.
