U0457Invalid Data Received From Information Center A

U0457 is a communication fault where a control module on the vehicle's Controller Area Network (CAN) bus reports that it has received invalid or corrupted data from the Information Center module, designated as 'A'. The detecting module sets this code when the data frames from the Information Center arrive with incorrect checksums, out-of-range values, or missing expected parameters, indicating a data integrity problem rather than a total loss of communication.
