Description:

This diagnostic trouble code is generated when the control software receives an excessively high number of incorrect CAN Bus messages or detects a severe problem in the connection to the vehicle CAN Bus (500 kBd).

Reaction:

The control software may have limited or no functionality due to the very high error rate in CAN Bus communication.

Recommendations:

• Inspect CAN Bus Wiring and Connections:
  • Check all CAN Bus wiring for damage, loose connections, or corrosion.
  • Ensure all connections are secure and properly seated.
• Monitor Communication Integrity:
  • Use diagnostic tools to monitor CAN Bus communication and identify the sources of errors.
  • Replace any faulty components causing communication issues.
• Check Control Units:
  • Ensure all control units connected to the CAN Bus are functioning correctly and not transmitting erroneous messages.
• Consult Technical Support:
  • Seek assistance from technical support if the issue persists to diagnose and resolve severe CAN Bus communication problems.

Note:

Maintaining a healthy CAN Bus network is essential for reliable vehicle operations. Regular inspections and addressing communication errors promptly can prevent significant issues.
