Description:

This diagnostic trouble code is generated when there is a data transfer problem between the TIQ control software and the CCU control software. The issue may involve intermittent or non-existent reception of CAN messages transmitted by the CCU control software, potentially due to a loose wire or other communication issues.

Reaction:

When this fault is detected, the control software may exhibit limited or no functionality, affecting the overall operation of the equipment.

Recommendations:

• Inspect CAN Bus Wiring and Connections:
  • Check for loose, damaged, or corroded wires and connectors between the TIQ and CCU control modules.
  • Repair or replace any faulty components.
• Verify CCU and TIQ Communication:
  • Use diagnostic tools to monitor CAN Bus messages and ensure proper communication between the TIQ and CCU control software.
  • Address any identified communication gaps or errors.
• Check for Interference:
  • Identify and eliminate sources of electrical interference that may disrupt CAN Bus communication.
  • Ensure proper grounding and shielding of CAN Bus cables.
• Update Software:
  • Install any available updates or patches for the CCU and TIQ control software.
• Consult Technical Support:
  • Contact technical support or the manufacturer for further assistance if the issue persists.

Note:

Maintaining secure and stable CAN Bus communication is essential for the reliable operation of control systems. Regular checks and updates can help prevent communication errors and ensure smooth performance.
