U0442: Your Car’s Communication System Needs Attention
The u0442 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 u0442 code is set when a receiving device detects a discrepancy in the information it receives from the Engine Control Module (ECM)Powertrain Control Module (PCM) ‘B’. This causes the integrity of the information to be questioned, resulting in an invalid data Diagnostic Trouble Code (DTC).
In summary, the u0442 fault code indicates that there is an issue with the information being exchanged between devices on the CAN network.
This can cause problems with the vehicle’s performance and should be addressed promptly to avoid further damage.
