BCU 523715.31 – Open Circuit Detected at Y72 Solenoid Valve for Draft Link Stabilizer. John Deere System Advisory.

BCU 523715.31 (BCU )

Code: 523715.31



Diagnostic trouble code BCU 523715.31 is initiated when the Body Control Unit (BCU) detects an open circuit in the wiring leading to the Y72 solenoid valve, which is responsible for controlling the draft link stabilizer. An open circuit suggests a break or disconnection within the electrical pathway, preventing the solenoid valve from functioning properly and affecting the stability and control of the draft link mechanism.


To prevent unpredictable behavior and potential mechanical issues, the BCU will likely disable the Y72 solenoid valve function, and the system may alert the operator with a diagnostic warning or malfunction indicator.


  • Inspect Wiring and Connectors: Thoroughly check all wiring and connectors associated with the Y72 solenoid valve for signs of damage, such as fraying, cuts, or disconnections, which might have led to the open circuit.
  • Test for Continuity: Utilize a multimeter to verify continuity in the circuit. This step is essential for locating the specific area where the circuit is broken.
  • Repair or Replace Faulty Wiring: Address any identified issues by repairing or replacing damaged wiring or connectors to restore proper electrical connectivity.
  • Ensure Solenoid Valve Functionality: After making the necessary repairs, test the Y72 solenoid valve to confirm it is operational and receiving adequate power.
  • Reset and Recheck the System: Clear the error code from the BCU’s memory and perform a system reset if required. Verify that the draft link stabilizer operates correctly in subsequent tests.


Maintaining electrical integrity in machinery controls like solenoid valves is crucial for operational reliability. Regular inspections and prompt repair of electrical faults are vital for preventing downtime and ensuring that the machinery continues to operate efficiently and safely. Proactive management of these systems can significantly mitigate the risk of equipment failure and maintain optimal performance.
