2011 Silverado Service Air Bag

Recently had the airbag light illuminate on my truck. I had a mechanic scan the truck but his scanner could not connect to the module. He said this meant the module has gone bad. Does this sound correct? I really don't want to spend $130 for the dealer to scan and tell me the same thing. Is the SDM still under the drivers seat on a 2011 like the 2007-8 that had the recall? Truck is a crew cab. I can't seem to find anything under there.

Depends on which scanner was used. Most aftermarket scanners won't read SIR modules. If it was a scanner that normally sees GM SIR modules, then it is probably dead. Although it could be a power,ground or network issue. Located under the console

It was large Autel diagnostic scanner, he said he had checked these trucks before. The first few days the light would actually flicker on and off leading me to think it was a connection problem. The other thing is that my seat belt warning light and chime has been completely inoperable since the light came on, is that normal or could it be part of the problem?
