GMC Troubleshooting Questions? Ask a Mechanic for Answers
HI there, I am Cam. Can I get your first name please?How did you stumble on the Airbag fuse fixing the rest of the issues?
OK, so if the Sdm (air bag module) is setting that code, it needs to be replaced. Its possible that it has issues that is killing the network. With that code confirmed, there is no diagnosis, replacement is the diagnosis. I suggest we verify that replacement fixes your other issue and if so, perfect. IF not lets follow up in here.
