U0431: The Lowdown On Your Car’s Invalid Data Received
The u0431 fault code is related to the Controller Area Network (CAN) in a vehicle.
CAN is a standard that connects automotive devices without a host computer. The devices exchange operating information and commands through programmed messages on serial data circuits.
