U0498 code meaning
Invalid Data Received From Telephone Control Module
What U0498 means
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.

What each part of U0498 means

What to do next
- Note U0498 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.
