Description:

This error code arises when there is a data transfer issue between the User Interface Controller (UIC) and the ECU, leading to intermittent or nonexistent reception of CAN messages concerning general transmission information.

Reaction:

This communication failure may result in the ECU receiving incomplete or incorrect information, potentially affecting the vehicle’s operational controls and user interface.

Recommendations:

• Inspect CAN Bus Wiring and Connections: Check for any loose connections or damaged wires in the CAN Bus system that could disrupt communication.
• Test CAN Bus Functionality: Use diagnostic tools to evaluate the functionality and integrity of the CAN Bus, focusing on the path from the UIC to the ECU.
• Identify and Resolve Interference Issues: Locate and mitigate any potential sources of electromagnetic interference affecting the CAN Bus.
• Replace Damaged Components: If any components of the CAN Bus are found to be faulty, replace them to ensure reliable data transmission.
• Reset ECU and Verify System Functionality: After making necessary repairs, reset the ECU to ensure all changes take effect and verify that communication with the UIC is consistent and correct.

Note:

Regular maintenance of the CAN Bus system and its components is crucial for ensuring effective communication and operation across vehicle control units. Addressing issues promptly helps maintain optimal performance and functionality.
