U0498 is logged when the telephone control module, the hands-free or Bluetooth unit, still sends frames but the head unit or body controller rejects their content. For Chrysler the lost-contact partner U0197 is the hands-free phone module (HFM); its bulletins 08-112-14 (2013-2015 Town & Country, Grand Caravan, Wrangler, Challenger and others) and 08-055-17 Rev. A (2012-2017 Journey, Charger, 300) restore dead Bluetooth or an HFM stuck at its loading screen with new module software. GM's Saab lists call the same partner the telephone control module. Where the phone unit also places emergency calls, the telematics code U0499 is the closer neighbour. No manufacturer documents U0498 publicly. Expect failed pairing or calls; no MIL.

Likely causes

Hands-free module software fault, cured by reprogramming

Module not booting fully or resetting, so its status values are invalid

Internal hardware fault of the telephone module

Symptoms

Bluetooth pairing or hands-free calls fail
Phone menu unavailable or stuck on a loading message
