RPT 523814.05 – Solenoid for PTO Speed 2 On, No Current Present at PAP Control Software

RPT 523814.05 (RPT )

Code: 523814.05



This diagnostic trouble code, RPT 523814.05, is generated when the PAP control software measures a current of less than 500 mA at the output to the solenoid for PTO speed 2 when the solenoid is turned on. This indicates that the circuit is open.


When this error is detected, the functionality of the rear PTO is significantly limited or entirely non-functional.


Inspect Solenoid Circuit:

  • Check the wiring and connections for the solenoid circuit for signs of an open circuit.
  • Repair or replace any damaged wires or connectors.

Test Current Levels:

  • Use diagnostic tools to measure the current levels at the solenoid for PTO speed 2.
  • Ensure the current is within the specified range when the solenoid is activated.

Verify Solenoid Operation:

  • Test the solenoid for proper operation and ensure it is receiving adequate current.
  • Replace the solenoid if it is found to be faulty.

Update Control Software:

  • Ensure that the PAP control software is updated to the latest version.
  • Apply any available patches or updates that address current regulation issues.

Consult Technical Support:

  • If the problem persists, consult with technical support or the equipment manufacturer for further assistance.
  • Provide detailed error logs and current measurements to aid in troubleshooting.


Proper current levels are essential for the correct operation of the solenoids and the PTO system. Regular inspections and maintenance of the electrical components can help prevent such issues.
