Check the breakers in the glove box. Make sure none are tripped.
When did the problem start? Anything special happening at that time?

check all the cab plugs. maybe the J1708 0r J1939 connections shorted out?.

When i get a chance later today, I'll see if I can dig up a copy of the schematic for the data link wires. But for now check your firewall connectors. The round 1's on the driver side (turn counter clockwise to remove) and the rectangular 1's on the passenger side (I believe its a 1\4" socket needed to remove them) also as Rawze said remove the ECM connectors and give them a check. they possibly washed dirt or water or even loosened or cut wires at those connectors with their high pressure wand.
