U0256Lost Communication With Front Controls Interface Module A
- Generic OBD-II code · Network
- How the car detects it
- Module A of the front controls interface collects radio and climate key presses in the middle of the dash and passes them to the network. At Ford this is the FCIM; for the 2011 Saab 9-5 GM labels U0256 as the infotainment faceplate control module. Ford cites the code directly: on 2023 Super Duty trucks a wrong measurement sequence during the body control module self-test could leave U0256:87 and several other codes in history status; if the BCM has no other codes, the MIL is off and the truck drives normally, they are to be ignored (SSM 51578). That the panel itself can go silent is shown by 2015-2017 F-150 trucks, where heavy CAN traffic froze the FCIM so A/C, radio and window switch control failed until a battery reset (SSM 46902). A real loss disables its keys; panel B is U025D.

- PossibleLoose connector or missing supply at the panel after dashboard work
- RareInternal failure of the control panel
