BCU 524224.02 – Information for Operator: Switch Off the Rear PTO Switch. John Deere Advisory.

BCU 524224.02 (BCU )

Code: 524224.02



Diagnostic trouble code BCU 524224.02 is an informational alert generated to notify the operator that the rear PTO (Power Take-Off) was activated after the HMS Plus (Headland Management System Plus) was engaged, despite the rear PTO not being programmed to operate within the HMS Plus sequences. This alert serves to prevent potential operational conflicts or inefficiencies, as the rear PTO activation is not synchronized with the automated management provided by HMS Plus.


The system does not automatically deactivate the rear PTO; instead, it issues this alert to prompt the operator to manually switch off the rear PTO. This is intended to align machine operation with the programmed sequences of HMS Plus and ensure safety and efficiency.


  • Manual Intervention Required: Manually switch off the rear PTO as advised by the diagnostic code to align operations with the HMS Plus settings.
  • Check HMS Plus Settings: Review the HMS Plus configuration to verify whether the rear PTO should be included or excluded from its sequences. Adjust the settings accordingly if integration is desired.
  • Operator Training: Ensure that all operators are familiar with the functionalities of HMS Plus and understand the implications of activating the rear PTO when it is not included in the HMS Plus program.
  • Reset Diagnostic Codes: After addressing the issue, reset any diagnostic codes that were triggered as a result of this situation to clear the system’s error log.
  • Consult Technical Support: If there is uncertainty about configuring or operating HMS Plus with PTO settings, or if issues persist, consult with John Deere technical support for further guidance.


Understanding the integration and operational parameters of systems like HMS Plus with PTO settings is crucial for efficient machine operation. Proper training and adherence to system guidelines can prevent operational errors and ensure that all machinery functions are optimized and used within their designed capacities. Regular updates and checks on the configuration of HMS Plus and related systems are recommended to enhance operational safety and efficiency.
