U0354Software Incompatibility With Hybrid/EV Battery Inductive Charger Control Module

U0354 is a generic network communication code indicating that a control module on the vehicle's data bus has detected a software incompatibility with the hybrid or electric vehicle battery inductive charger control module. The computer is not reporting a hardware failure of the charger itself, but rather that the charger module's software version, calibration, or configuration does not match what other modules expect, preventing proper coordinated operation of the inductive charging system.
