U0258Lost Communication With Radio Transceiver
- Generic OBD-II code · Network
- How the car detects it
- Despite its name this unit has nothing to do with the audio tuner: Ford's radio transceiver module (RTM) handles the wireless link to keys and remote accessories. On the 2021-2022 Bronco Sport, Ford traced No Key Detected messages to blocked key frequencies or a flat key battery and advised laying the key in the forward console tray, the backup position close to the RTM (SSM 50341); RTMs in recent F-150 and Super Duty trucks work on a changed frequency, so only one accessory keypad part fits (SSM 54546). No manufacturer documents U0258 itself publicly, nor a timeout. A receiver such as the body control module would set it when RTM messages stop on the bus. Keyless entry, key detection at start-up or remote functions may then fail; corrupt RTM data are U0559, a remote start module is U0254.
