RPT 524218.19 – Park Position Signal Fault

RPT 524218.19 (RPT )

Code: 524218.19



This diagnostic trouble code, RPT 524218.19, is generated when the park position signal cannot be determined and provided on the CAN bus by the control software for PTA (AutoPowr™/IVT™ transmission), PTQ (PowrQuad™ transmission), or PTD (DirectDrive transmission). A transmitted replacement value generates this diagnostic trouble code. In its active state, this fault can also generate a diagnostic trouble code at the PTA, PTQ, or PTD control software. These diagnostic trouble codes take priority.


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


Inspect Park Position Sensor:

  • Check the park position sensor for proper operation.
  • Replace the sensor if it is found to be defective.

Inspect Wiring and Connections:

  • Check the wiring and connections associated with the park position sensor for signs of damage, corrosion, or loose connections.
  • Repair or replace any damaged wires or connectors.

Verify CAN Bus Communication:

  • Use diagnostic tools to test the CAN bus communication for any irregularities or failures.
  • Ensure that all CAN messages from the PTA, PTQ, or PTD control software are being correctly transmitted and received by the RPT control software.

Update Control Software:

  • Ensure that the PTA, PTQ, PTD, and RPT control software are all updated to the latest versions.
  • Install any available patches or updates that address CAN bus communication issues.

Consult Technical Support:

  • If the problem persists after initial troubleshooting, consult with technical support or the equipment manufacturer for further assistance.
  • Provide detailed information about the issue, including any error logs or diagnostic reports.


Regular maintenance and inspections of the park position sensor and associated wiring can help prevent such issues. Ensuring that the control software is up-to-date is crucial for maintaining reliable operation.
