Lost Communication With Hybrid/EV Battery Inductive Charging Module

Moderate severity

What it means

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?
