U048AInvalid Data Received From Digital Disc Player/Changer Module C

U048A is a communication fault indicating that a control module received invalid or corrupted data from the digital disc player/changer module, designated as module C on the vehicle's communication network. The computer detected a message from the disc player that failed its internal validity check, such as a missing checksum, out-of-range value, or malformed data packet, rather than a complete loss of communication.
