A speech recognition module turns spoken commands into actions for phone, audio or navigation. Some makers place it in a separate box: FCA built Uconnect Voice Command into its hands-free unit (HFM) of 2012-2017 Journey, Charger and 300. Old software could leave it stuck while loading, unresponsive and off the bus, or deaf to the voice key on the steering wheel, and a reflash cured it (08-055-17 REV. A). FCA records such a silent unit as U0197, the telephone module code, not as U0263. GM shows that a voice complaint need not lie in the recognition unit: on the 2014 Cadillac ATS the cluster displayed Unable to Start Speech Recognition although voice control worked, fixed by cluster software (PIC6008C). No manufacturer documents U0263 publicly. Voice commands are then ignored; U0564 means corrupt data.

Likely causes

Voice module software hangs during start-up, fixed by reflash
Voice module without power or ground, or connector loose
Fault message created by cluster or head unit software although the module works
Internal failure of the speech recognition module

Symptoms

  • No reaction to the voice button on the steering wheel
  • Message that speech recognition cannot be started
  • Hands-free phone functions unavailable where combined in one module
