Description:

This diagnostic trouble code (TCU 002005.09) is generated when a data transfer problem occurs between the UIC and TCU. The reception of CAN messages concerning general transmission information (clutch pedal, acceleration, transmission ratios, etc.) transmitted by UIC is intermittent or nonexistent, which could be due to a loose wire or other communication issues.

Reaction:

When this error code is detected, the equipment may experience intermittent performance issues or erratic behavior due to the lack of reliable transmission data. The system might display warnings or enter a protective mode to prevent potential damage.

Recommendations:

1. Inspect CAN BUS Communication:

• Check Connections: Ensure that all CAN BUS connections between the UIC and TCU are secure and free of corrosion.
• Inspect for Loose Wires: Look for any loose wires or connectors that could cause intermittent data transfer.

2. Test Communication Integrity:

• Use Diagnostic Tools: Use diagnostic tools to test the integrity of the CAN BUS communication.
• Monitor Data Transfer: Monitor the data transfer between the UIC and TCU to identify any interruptions.

3. Examine Wiring and Connectors:

• Inspect Wiring: Check all wiring and connectors associated with the CAN BUS system for damage or disconnection.
• Repair or Replace: Repair or replace any faulty wiring or connectors.

4. Verify UIC Functionality:

• Test UIC: Ensure that the UIC is functioning correctly and transmitting accurate data.
• Update Software: Update the UIC software if necessary.

Note:

Maintaining reliable CAN BUS communication between the UIC and TCU is essential for optimal equipment performance. Regular inspections and prompt repairs can help prevent data transfer issues.
