U0564 code meaning
Invalid Data Received From Speech Recognition Module
What U0564 means
In-car voice control lets the driver place calls, pick stations or play music by spoken command, in newer systems even in natural sentences. Some makers house it in a module of its own: FCA put Uconnect voice recognition into a hands-free module (HFM) on 2012–2017 Journey, Charger and 300; with old software it could hang while loading, ignore the steering-wheel voice key or pick up background noise, and a reflash fixed it (08-055-17 REV. A, where a silent HFM sets U0197). Ford runs voice commands on the SYNC computer (APIM). U0564 is set when a dedicated speech recognition module sends data that fail checks; U0263 covers lost contact. No manufacturer documents U0564 publicly. Voice commands may be ignored, misread or cause wrong actions.
U0564 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0564
- Voice control does not respond to the steering-wheel button
- Voice commands misrecognized or system stuck while loading
Common causes of U0564
- Most likelySpeech recognition software outdated or faulty (fixed by reflashing)
- Less likelyUnsupported language selection or mismatch between module and head unit settings
- Less likelySpeech recognition module internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0564 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 64 | The exact fault in that area. |
What to do next
- Note U0564 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.
Questions about U0564
What does U0564 mean?
U0564 means "Invalid Data Received From Speech Recognition Module". In-car voice control lets the driver place calls, pick stations or play music by spoken command, in newer systems even in natural sentences. It is a generic code, so it means the same on every make.
Is it safe to drive with U0564?
U0564 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0564 fail an emissions test?
U0564 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0564 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will U0564 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
