Description:

This diagnostic trouble code, RPT 000186.01, is generated when the rear PTO does not start up correctly after being turned on. The rear PTO is turned off and can only be turned back on again after 30 seconds. This indicates that the rear PTO is overloaded, possibly due to an implement being blocked or sluggish, or too much slip at the rear PTO clutch.

Reaction:

When this error is detected, the rear PTO shuts down to protect the system and can only be restarted after a 30-second delay. This impacts the operation of the rear PTO and the connected implement.

Recommendations:

Inspect Rear PTO Implement:

• Check the implement connected to the rear PTO for any blockages or mechanical issues that could cause overload.
• Ensure the implement is properly maintained and lubricated.

Examine PTO Clutch:

• Inspect the rear PTO clutch for signs of excessive slip or wear.
• Adjust or replace the clutch if necessary.

Verify PTO Speed Sensor:

• Ensure the rear PTO speed sensor is functioning correctly and transmitting accurate data.
• Replace the sensor if it is found to be faulty.

Check PTO Circuit:

• Inspect the wiring and connections in the rear PTO circuit for any signs of damage, corrosion, or loose connections.
• Repair or replace any damaged components.

Monitor PTO Operation:

• After addressing the issue, monitor the rear PTO operation to ensure it starts and runs correctly.
• Record any further issues to aid in ongoing diagnostics.

Note:

Overloading the rear PTO can cause significant wear and damage to both the PTO system and the connected implement. Regular maintenance and proper use of the PTO and implement can prevent such issues.
