Description:

This error code, TEC 001231.14, is triggered when the data received by the TEC control unit from the vehicle CAN BUS are significantly faulty or incomplete. This indicates a severe problem in the CAN BUS communication network, which could be due to extensive interference, critical wiring issues, or major device malfunction.

Reaction:

When this error occurs, the control unit may experience severe communication issues with other vehicle systems, potentially leading to major performance issues or complete inoperability. This can significantly impact the machine’s functionality and safety.

Recommendations:

Inspect CAN BUS Connections Thoroughly:

• Conduct a detailed inspection of all CAN BUS connections for secure fitting and signs of damage or corrosion.
• Ensure all connectors are properly seated and cables are intact.

Eliminate Interference Sources:

• Identify and mitigate potential sources of electromagnetic interference disrupting CAN BUS communication.
• Ensure proper shielding and routing of CAN BUS cables away from high-interference areas.

Update Firmware:

• Verify that the firmware of the control unit and all connected devices is the latest version. Update if necessary.

Comprehensive Testing of CAN BUS Devices:

• Use advanced diagnostic tools to test the functionality of all devices connected to the CAN BUS.
• Replace or repair any devices found to be malfunctioning or contributing to high error rates.

Consult with Technical Support:

• If the problem persists, escalate the issue to the manufacturer’s technical support for in-depth diagnostics and assistance.
• Provide detailed information about the error code and the steps taken to resolve it.

Ongoing Monitoring:

• After implementing the recommended actions, continuously monitor the equipment to ensure the error does not recur.
• Maintain a detailed log of any further occurrences to assist in future troubleshooting.

Note:

Maintaining a stable and interference-free electrical environment is crucial for the proper functioning of the CAN BUS network. Regular updates and preventive maintenance are essential to minimize the risk of severe communication errors.
