PTF 523905.14 (PTF )

Code: 523905.14



This diagnostic trouble code is generated when the PTF control software detects that the voltage in the positive lead of the front PTO solenoid valve is above 16 V. This indicates a short to a higher voltage source.


When this code is detected, the front PTO may exhibit limited or no functionality.


  • Inspect Solenoid Valve Circuit:
    • Check for a short to a higher voltage source in the wiring to the front PTO solenoid valve.
    • Repair or replace any damaged wires.
  • Test the Solenoid Valve:
    • Verify the functionality of the front PTO solenoid valve using diagnostic tools.
    • Replace the solenoid valve if it is found to be faulty.
  • Check Connectors:
    • Ensure that all connectors are properly seated and free of corrosion.
    • Clean or replace connectors as needed.


Maintaining proper voltage levels and ensuring there are no shorts to higher voltage sources is crucial for the front PTO solenoid valve’s operation.
