U0558 Invalid Data Received From Front Controls/Display Interface Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

Simpler infotainment systems put buttons and a small screen into one unit, the front controls/display interface module. Ford calls it FCDIM, used for example with the 4-inch audio display, and the GM-built 2011 Saab 9-5 lists U0257 for its info display module/infotainment faceplate control module. Ford bulletins show its typical weak spot, the software: on the Escape from 2013 to 2016 and on 2016 Focus, Transit Connect and Transit vans, AM/FM presets could not be stored or recalled and the preset keys acted erratically until the FCDIM was reprogrammed (SSM 46891, 47234). U0558 means the combined unit sends frames that receivers reject; U0257 stands for lost contact, while U0556 and U0557 cover separate display and button modules. No bulletin cites U0558. Radio keys or the small display may misbehave.

Likely causes

Software fault in the combined controls/display unit (Ford remedy is reprogramming)
Unit programmed with a calibration for a different equipment level
Front controls/display interface module internally faulty

Symptoms

  • Radio presets cannot be stored or recalled, preset keys act erratically
  • Small audio display blank or showing wrong settings
