Q: What does code U0255 mean?

Lost Communication With Front Display Interface Module. U0255 is a network communication code indicating that a control module, usually the body control module or gateway, has lost the expected data messages from the front display interface module over the vehicle's communication bus. The computer sets this code when it stops receiving regular status frames from that display module for a calibrated period, not necessarily because the display itself has failed.
