Q: What does code U0598 mean?

Invalid Data Received From AC/DC Converter Control Module B. U0598 means the module that monitors an AC/DC converter control module (inverter B) received data that it judged invalid, so it flagged the message as corrupt or out of range. The receiving computer did not lose communication entirely; it got a frame it could not trust, which points to a data integrity or signal problem rather than a dead module.
