U0558 code meaning
Invalid Data Received From Front Controls/Display Interface Module
What U0558 means
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.

Symptoms of U0558
- Radio presets cannot be stored or recalled, preset keys act erratically
- Small audio display blank or showing wrong settings
Common causes of U0558
- Most likelySoftware fault in the combined controls/display unit (Ford remedy is reprogramming)

What each part of U0558 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 58 | The exact fault in that area. |
What to do next
- Note U0558 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
