RPT 523908.31 – Remote Control Switch for Rear PTO, Malfunction

RPT 523908.31 (RPT )

Code: 523908.31



This diagnostic trouble code, RPT 523908.31, is generated when the OIC control software detects an open circuit in the circuit for the remote control switch for the rear PTO. A transmitted replacement value generates this diagnostic trouble code in the RPT control software. In its active state, this fault also generates a diagnostic trouble code at the OIC control software. The OIC diagnostic trouble codes take priority.


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


Inspect Remote Control Switch Circuit:

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

Test Remote Control Switch:

  • Use diagnostic tools to test the remote control switch for proper operation.
  • Replace the switch if it is found to be defective.

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 OIC control software are being correctly transmitted and received by the RPT control software.

Update Control Software:

  • Ensure that both the OIC and RPT control software are updated to the latest versions.
  • Install any available patches or updates that address circuit and communication issues.

Consult Technical Support:

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


Regular maintenance and inspections of the remote control switch circuit and associated wiring can help prevent such issues. Keeping the control software updated is crucial for reliable operation.
