U0350Software Incompatibility With Active Grille Air Shutter Module C

U0350 is a network communication fault indicating that the active grille air shutter module C reports a software incompatibility with the vehicle's controller area network (CAN) or body control module. The computer has detected that the module's firmware or calibration does not match the version expected by the rest of the system, so it cannot reliably command the grille shutters.
