What does x065 mean?

The system bus (CAN) has entered a BUS-OFF state (displayed as CE4), indicating that too many faulty telegrams have been transmitted. This often means the CAN node has ceased transmitting due to excessive errors. The monitoring relates to parameter C0595 and typically points to severe bus communication problems.
