This is going to require a trip to the dealer. The heart of the problems is the radio. The engineers built the Body Computer into it to prevent people from replacing them with aftermarket radios. All the other dozens of computers are told to "wake up" by the radio when the ignition switch is turned on.
The fault code refers to two computers disagreeing with the programming of the air bag system, so it may be necessary to simply unlock one of them or one may need new software installed. GM has it figured out so most independent shops can't do the programming, so I don't know how serious this will be. I only know they don't do it for free.
