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. The u0431 code is set when a receiving device detects a discrepancy in the information it receives from the Body Control Module (BCM) ‘A’.
This causes the integrity of the information to be questioned, resulting in an invalid data Diagnostic Trouble Code (DTC). In simpler terms, the u0431 code means that the BCM ‘A’ is sending incorrect data to another device on the CAN network.
