U0457 code meaning
Invalid Data Received From Information Center A
What U0457 means
Information center A is the first of two driver information displays defined alongside the instrument cluster, in practice often the central screen or head unit of the infotainment system. U0457 is stored when a listener still hears this display but rejects what it sends, for example because a message counter or checksum fails, the kind of protection AUTOSAR specifies for safety-related frames; a silent display gives U0156 instead. No manufacturer documents U0457 publicly. For the partner itself, Mazda treats information center A as its connectivity master unit (SA-029/20, Mazda3 and CX-30), and Volvo's central electronic module logs U015600 when the Sensus screen stays black (TJ 25872). Settings, messages or audio shown on that screen may be wrong or missing, while driving stays normal and no MIL lights. U0458 is center B.

What each part of U0457 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 57 | The exact fault in that area. |
What to do next
- Note U0457 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.
