Description:

This diagnostic trouble code (DTC) is generated when there is a data transfer problem between the ECU control software and the TIA control software. This can occur if the reception of messages sent on the CAN BUS by the ECU control software is intermittent or non-existent, indicating a potential open circuit, short circuit, or faulty CAN BUS terminating resistors.

Reaction:

Limited or no function of the control software due to unreliable data communication.

Recommendations:

Inspect CAN BUS Wiring and Connections:

• Check all CAN BUS wiring and connectors for any signs of damage, corrosion, or loose connections.
• Repair or replace any faulty wiring or connectors.

Verify Terminating Resistors:

• Ensure that the CAN BUS network is properly terminated with functioning resistors.
• Replace any faulty or missing terminating resistors.

Check for Open or Short Circuits:

• Use diagnostic tools to check for open circuits or short circuits in the CAN BUS lines.
• Repair any identified circuit issues.

Update ECU and TIA Control Software:

• Ensure that both the ECU and TIA control software are up-to-date with the latest versions provided by the manufacturer.

Consult Technical Support:

• If the issue persists, consult technical support for further diagnostic procedures or potential hardware issues.

Note:

Regular inspection and maintenance of the CAN BUS network can prevent communication errors. Ensuring all components are functioning correctly is essential for reliable data transfer.
