U0073 Chevrolet - Control Module Communication Bus off.

Anyone have any idea what's most likely going on? Could getting tuned help? Car spools fine.

 

That's a communication/network code so something is disconnected or not connecting properly, or worst case scenario something got fried

 

I just noticed my boost gauge flickers on the second turn. Then it works fine

 

A tune will probably not fix the problem, it's an electrical problem but ist going to be hard to give you an exact fix to the problem. But check all connections going to the ecm or bcm make sure nothing got loose

 

Your pm is full what the other code you have? Also post the cars mods and year and that good stuff
