Description:

This diagnostic trouble code is generated when the TIA control software is unable to determine the clutch torque command (DCTL) and cannot provide the CAN BUS with relevant data. A transmitted replacement value generates this diagnostic trouble code in the PTA control software.

Reaction:

Limited or no function of the control software until the error is corrected, indicating a critical issue with CAN BUS communication.

Recommendations:

Inspect TIA Control Software:

• Verify that the TIA control software is functioning correctly.
• Update the TIA control software if necessary.

Check CAN BUS Communication:

• Ensure that the CAN BUS communication between the TIA and PTA control software is intact.
• Repair any communication issues.

Examine Wiring and Connectors:

• Inspect all wiring and connectors associated with the CAN BUS for signs of damage or disconnection.
• Repair or replace any damaged components to ensure proper electrical connections.

Consult Technical Support:

• If the issue persists, consult technical support or the manufacturer for further diagnosis and assistance.

Note:

Maintaining accurate clutch torque command communication is essential for proper vehicle operation. Regular inspection and maintenance can help prevent communication issues.
