Description:

This diagnostic trouble code is generated when there is a data transfer problem between the TIQ control software and the ECU control software. The issue may involve intermittent or non-existent reception of CAN messages transmitted by the ECU 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 vehicle’s performance.

Recommendations:

• Inspect CAN Bus Wiring and Connections:
  • Check for loose, damaged, or corroded wires and connectors in the CAN Bus network.
  • Repair or replace any faulty components.
• Verify ECU and TIQ Communication:
  • Ensure that the ECU and TIQ control software are properly communicating.
  • Use diagnostic tools to monitor CAN Bus messages and identify communication gaps.
• 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 ECU and TIQ control software.
• Consult Technical Support:
  • Contact technical support or the manufacturer if the issue persists.

Note:

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