U0598Invalid Data Received From AC/DC Converter Control Module B
- Generic OBD-II code · Network
- How the car detects it
- A second AC/DC converter exists where makers raise AC charging power by fitting two charger units; the F-150 Lightning, for instance, can be ordered with two 40-amp charger units that together reach 19.2 kW. Patents show how the pair is run: Porsche's US10029578B2 has one charger lead and the other follow via a communication line only, and Hyundai's US10270273B2 uses a master controller with slave controllers per power module. U0598 means the second unit keeps reporting but its data are rejected, so the vehicle typically falls back to the first charger and charges more slowly. No manufacturer documents U0598 publicly. The lost-communication counterpart in current code lists is U0297.
