Description:

This diagnostic trouble code is generated when the control software receives too many incorrect CAN Bus messages or detects a general problem in the connection to the vehicle CAN Bus (500 kBd). This could be due to communication errors, faulty wiring, or hardware issues.

Reaction:

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

Recommendations:

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

Note:

Maintaining a healthy CAN Bus network is crucial for reliable vehicle operations. Regular inspections and prompt attention to communication errors can prevent significant issues.
