Lost Communication With 'Door Switch F'. U0220 is a generic network communication code indicating that one or more control modules have lost the expected signal from the door switch circuit designated as 'F'. The computer detected that the door switch message, typically broadcast over the vehicle's controller area network (CAN) bus, is missing or intermittent, so other modules can no longer confirm that door's open or closed status.
