Description:

This diagnostic trouble code, RPT 523813.03, is generated when the PAP (Power Accessory Point) control software detects a voltage that is too high (12 volts) at the output to the solenoid for PTO speed 1 when the solenoid is turned on. This indicates a circuit that is open or shorted to 12 volts.

Reaction:

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

Recommendations:

Inspect Solenoid Circuit:

• Check the wiring and connections for the solenoid circuit for signs of an open circuit or a short to 12 volts.
• Repair or replace any damaged wires or connectors.

Test Voltage Levels:

• Use diagnostic tools to measure the voltage levels at the solenoid for PTO speed 1.
• Ensure the voltage is within the specified range when the solenoid is activated.

Verify Solenoid Operation:

• Test the solenoid for proper operation and ensure it is receiving the correct voltage.
• 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 voltage 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 voltage measurements to aid in troubleshooting.

Note:

Proper voltage 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.
