Description:

This diagnostic trouble code, RPT 524218.31, is generated when the PTA (AutoPowr™/IVT™ transmission), PTQ (PowrQuad™ transmission), or PTD (DirectDrive transmission) control software detects an open circuit at the park position sensor. 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 PTA, PTQ, or PTD control software. This diagnostic trouble code takes priority.

Reaction:

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

Recommendations:

Inspect Park Position Sensor Circuit:

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

Test Park Position Sensor:

• Use diagnostic tools to test the park position sensor for proper operation.
• Replace the sensor 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 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 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.

Note:

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