U0559Invalid Data Received From Radio Transceiver
- Generic OBD-II code · Network
- How the car detects it
- Despite the name, the radio transceiver is not the audio tuner but the module that exchanges radio signals with keys and wireless accessories. Ford's name is RTM: on 2021–2022 Bronco Sport, jammed passive-key frequencies or a weak key battery could trigger No Key Detected, solved by placing the key in the console backup spot close to the RTM (SSM 50341); on recent F-150 and Super Duty trucks the RTM uses a new frequency, so only one specific accessory keypad pairs (SSM 54546). Keyless systems commonly work at 315 or 433.92 MHz. U0559 means the RTM's messages arrive but are invalid; U0258 means none arrive. No bulletin names U0559. Keyless entry, remote functions or key detection may fail.
