Order of inspection
U0075 Control Module Communication Bus C Off High
The U0075 code means a module detected so many errors on communication bus C that it disconnected itself from the network so it would not block it. It usually shows up together with several lost communication codes. Depending on which network is affected, the engine, transmission or brakes can be involved.
