Description:

Diagnostic trouble code BCU 600006.31 is triggered when the CommandCenter (DTI) receives a BCU diagnostic trouble code via the CAN (Controller Area Network) bus that is not recognized or stored in the DTI’s memory. This “general” diagnostic trouble code allows the CommandCenter to display an alert regarding this unknown BCU code, indicating that there is a communication or system error involving codes that the DTI cannot categorize or properly interpret based on its current programming.

Reaction:

The system does not directly react to rectify the unknown trouble code but provides notification to prompt further investigation. This general code serves as a placeholder to alert the operator that there is a diagnostic issue requiring attention, which is not immediately definable within the existing parameters of the DTI.

Recommendations:

• Software Update: Ensure that the software for the CommandCenter and the BCU is up-to-date. An update may be required to include the unknown code in the DTI’s memory.
• Diagnostic Scan and Verification: Conduct a comprehensive diagnostic scan using John Deere Service Advisor or other compatible diagnostic tools to identify any underlying issues that could be causing the unrecognized code.
• Consult Technical Support: If updating software and conducting scans do not resolve the issue, consult John Deere technical support for assistance. There may be new codes or issues that are not yet incorporated into the system’s diagnostic tools.
• Reset System and Monitor: After attempting updates and diagnostics, reset the system to clear any residual codes and monitor the equipment to see if the unknown code reappears.
• Record and Report: Keep a record of the unknown code and any related symptoms or issues. Reporting these details to a service technician can help with troubleshooting and identifying software or database updates that might be needed.

Note:

Encountering an unknown diagnostic trouble code highlights the importance of keeping system software and diagnostic tools up to date. Regular maintenance checks, updates, and training on the latest diagnostics will help minimize the occurrence of such issues and ensure that all equipment operates reliably and efficiently.
