U0257Lost Communication With Front Controls/Display Interface Module
- Generic OBD-II code · Network
- How the car detects it
- Some vehicles combine keys and screen in a single front controls/display interface module. Ford calls such a unit FCDIM, for example with the small audio display on the Escape (2013-2016) and the 2016 Transit Connect, Transit and Focus (SSM 47234), while the 2011 Saab 9-5 reserves U0257 for a unit merging info display and faceplate. Audi documents the code itself for the 2026 Q3: the panoramic display (KX2) ignored touches on the central MMI screen, and U025700 was active in information electronics control unit 1 (address 005F). The display's own software was to blame; dealers replace the display, while improved software follows from model year 2027 (TSB 2082126/1). A silent unit leaves both its keys and its screen without function; separate units use U0255 and U0256.
