U011FLost Communication With V2X Module
- Generic OBD-II code · Network
- How the car detects it
- U011F concerns the V2X module, the radio unit through which a car exchanges messages with other vehicles, roadside infrastructure, pedestrians' devices or the network (vehicle-to-everything), either via short-range DSRC/ITS-G5 or via cellular C-V2X. It passes alerts such as an approaching hazard or signal-phase information on to the driver and to assistance systems. Another module stores U011F once the V2X unit's periodic frames stop. No manufacturer documents the code publicly; since the module has no role in emission control, a MIL is not expected. U042A covers invalid V2X data, U0198 a lost telematics module. For the driver the connected warnings simply disappear, sometimes with a cluster message; the car drives normally.
