09 S-80 all communication loss issues
Hello ladies and gentlemen. I could really use some help here well the dealership more then me. So basically 1 day after work. I went out to my car to start it and got a ton of service messages on the dashboard. Apparently all of the symptoms pointed to a CEM Issue.
We replaced that and come to find out. There is zero communication with any system and their computer and the car. The dealer told me they checked for continuity between wires that allow communication and said that nothing was showing broken. Any ideas of what might be the problem? I've been without my car for almost two months and my chevy 3500 is drinking a hole in my pocket.if you need any more information please feel free to ask. Have a great day
