BCU 524224.14 – Information for Operator: Switch On the Rear PTO Switch. John Deere Advisory.

BCU 524224.14 (BCU )

Code: 524224.14



Diagnostic trouble code BCU 524224.14 is an informational alert generated to notify the operator that the rear PTO (Power Take-Off) switch needs to be turned on when the HMS Plus (Headland Management System Plus) is activated, but the rear PTO is not yet engaged. This alert is specifically aimed at ensuring that the rear PTO is activated as part of the programmed operations within HMS Plus, which is designed to optimize the tractor’s performance by automating certain functions during headland turns or specific field operations.


The system does not automatically activate the rear PTO; instead, it provides this notification to guide the operator to manually engage the rear PTO to comply with the HMS Plus programmed sequences.


  • Manual Activation Required: Manually turn on the rear PTO as instructed by the diagnostic code to ensure it aligns with the HMS Plus operational programming.
  • Verify HMS Plus Programming: Check the HMS Plus settings to confirm that the rear PTO activation is correctly programmed and synchronized with other automated functions.
  • Operator Training: Ensure that all operators understand how to operate the rear PTO in conjunction with HMS Plus, and are aware of the need to activate the PTO under specific conditions dictated by the system.
  • Reset Diagnostic Codes: After activating the rear PTO and ensuring it is functioning as part of the HMS Plus sequence, reset any diagnostic codes to clear the system’s error log.
  • Continuous Monitoring: Keep monitoring the system’s performance to ensure that the PTO and HMS Plus are functioning correctly together, particularly after making adjustments or reconfigurations.


Proper synchronization of the PTO with automated systems like HMS Plus is essential for maximizing the efficiency and effectiveness of agricultural operations. Regular training sessions and updates on system functionalities can help prevent operational discrepancies and ensure smooth functioning of all integrated systems.
