FCC 000639.14 (FCC 639.14)

Code: 000639.14

Shortcode: 639.14

Description:

This error code indicates a very high error rate in CAN Bus messages at a 500 kBd rate. This suggests a general problem with the connection to the Vehicle CAN Bus, potentially due to bus overload, faulty nodes, or issues in the control software.

Reaction:

The control software will have limited or no functionality due to the very high error rate, severely impacting CAN bus communication and overall machine operation.

Recommendations:

  • Comprehensive CAN Bus Diagnostics: Perform in-depth diagnostics on the CAN bus to identify and rectify the cause of the high error rate.
  • Inspect and Replace Faulty Components: Check for and replace any faulty CAN bus components or wiring.
  • Reduce CAN Bus Load: If possible, reduce the load on the CAN bus to alleviate communication issues.
  • Update Firmware and Software: Ensure all firmware and control software are up-to-date to support efficient CAN bus communication.
  • Seek Expert Assistance: Engage John Deere technical support for advanced troubleshooting and resolution.

Note:

Very high error rates can lead to critical failures in communication systems. Immediate and thorough action is required to restore reliable CAN bus operations.
