Code U0457 indicates that a control module on the vehicle network has received invalid data from the Information Center module (often the instrument cluster or a central display). This is a communication error, meaning the data sent by the Information Center is corrupted or implausible, not necessarily that the module itself has failed.
The information center module itself may have an internal fault, software glitch, or corrupted memory causing it to send invalid data. This is the most common cause.
Low voltage, intermittent power, or a bad ground connection to the information center module can cause erratic operation and invalid data transmission.
Wiring issues such as shorts, opens, or high resistance in the CAN bus network between the information center and other modules can corrupt data signals.
Poor connections at the information center module or at inline harness connectors can cause intermittent communication faults.
A weak battery or charging system problem can cause multiple modules to behave unpredictably, leading to communication errors like U0457.
Rarely, the module that requested the data may have an internal fault causing it to misinterpret valid data. This is the least likely cause and should only be considered after all other possibilities are ruled out.
Almost never. The PCM is usually the receiver of the invalid data, not the cause. Replacing the PCM without diagnosing the information center module, wiring, or power supply is a common misdiagnosis and will not resolve the issue.
In most cases, yes, the vehicle will remain drivable. However, you may lose important information from the instrument cluster, and other systems may be affected. It should be diagnosed and repaired to ensure safe operation.
No, U0457 is a generic network code defined by SAE standards. It can appear on any vehicle equipped with an information center module that communicates over CAN bus, though the exact module name may vary by manufacturer.
The most common fix is repairing a poor connection, restoring proper power or ground to the information center module, or replacing the information center module itself if it has failed internally.
