U0500Invalid Data Received From Communication Module
- Generic OBD-II code · Network
- How the car detects it
- The public code lists checked do not carry U0500 at all, so neither its status as a generic code nor its wording can be confirmed. In the generic numbering, an invalid-data code usually mirrors the lost-communication code of the same module 0x301 lower (U0200 to U0501, U0199 to U049A); for U0500 that partner would be U01FF, which is not assigned in those lists either, so a reserved slot is likely. No manufacturer bulletin found uses U0500. If a tool shows it, read the make-specific meaning first. By analogy only: a telematics unit links the car to mobile networks for remote and emergency services, and invalid frames from it would disable those services without affecting the engine; the defined code for that unit is U0499.
- What you may notice
- Code present without any noticeable fault
- Remote app, emergency call or online services unavailable (if it concerns the telematics unit)
- Likely causes
- LikelyCode read with a manufacturer-specific definition that differs from the generic list
- PossibleScan tool decoding the stored fault number incorrectly
- RareTelematics or communication unit sending corrupted frames (analogy to U0499)
