U0214Lost Communication With Remote Function Actuation Module
- Generic OBD-II code · Network
- How the car detects it
- U0214 stands for the remote function actuation module, the receiver for key fob, passive entry or phone as a key. Ford calls it RFA: SSM 51571 (Mustang Mach-E 2021–2023) and SSM 54773 (Nautilus 2021–2023) describe phone as a key failing and U0214 in several modules because the RFA hangs in programming mode following an over-the-air update; one minute without the RFA fuse in the BCM and a reprogramming bring it back. GM bulletin 15-NA-004 (Acadia 2013–2016) lists U0214 with many other codes when the slow LAN line feeding the remote door lock receiver gets squeezed by the rear HVAC duct in the headliner, giving intermittent no-crank. Ford's 2014 list marks no MIL.
