Description:

This error code indicates that too many incorrect CAN Bus messages are being received, suggesting a general problem at the connection to the Vehicle CAN Bus (500 kBd). Such a high error rate can severely disrupt communication within the vehicle’s network.

Reaction:

When this error is detected, the control software will limit or disable certain functions to prevent potential damage and ensure safe operation despite the very high error rate.

Recommendations:

Inspect CAN Bus Network:

• Thoroughly check the CAN Bus wiring and connections for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Verify Terminating Resistors:

• Ensure the terminating resistors at both ends of the CAN Bus network are functioning correctly. Replace if defective.

Monitor CAN Traffic:

• Use diagnostic tools to monitor CAN Bus traffic and identify any sources of incorrect messages.

Check for Electrical Interference:

• Identify and mitigate any sources of electrical interference that may be affecting CAN Bus communication.

Update Control Software:

• Ensure that the control software is up-to-date and optimized for handling CAN Bus communication.

Consult Technical Support:

• If the issue persists, consult technical support for further assistance in diagnosing and resolving the very high error rate issue.

Note:

Maintaining the integrity of the CAN Bus network is crucial for reliable vehicle communication. Regular inspection and maintenance can help prevent such issues from arising.
