RPT 523812.04 – Solenoid for PTO Speed 2 On, Current Too High at PAP Control Software

RPT 523812.04 (RPT )

Code: 523812.04



This diagnostic trouble code, RPT 523812.04, is generated when the PAP control software measures a current above 30 A when the solenoid for PTO speed 2 is turned on. This indicates a grounded circuit.


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 a grounded 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 not drawing excessive 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.


High current levels can cause significant damage to the solenoids and the PTO system. Regular inspections and maintenance of the electrical components can help prevent such issues.
