U058CInvalid Data Received From Active Grille Air Shutter Module C

U058C is a communication fault where the engine control module (ECM) or body control module (BCM) receives data from the active grille air shutter module that it considers invalid or out of range. The computer has detected a message from the shutter module that fails its internal plausibility checks, such as a position value that does not match the commanded state or a signal that contradicts other sensor inputs.
