U014B Lost Communication With Hybrid/EV Battery Inductive Charging Module
ECU lost CAN communication with the inductive charging module (wireless charging of HV battery). A communication loss with this module breaks any function relying on its data — diagnostic tools may show 'no response' and dependent modules can fall into limp mode.
Is it safe to drive with U014B?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
