1. 1

   Check the 540 PTO button on the armrest/console for physical damage, sticking, or debris preventing it from making a clean contact.

2. 2

   Using a multimeter, test the PTO 540 switch for proper continuity when pressed and released. If the switch does not show a clear open/closed state, it has failed internally.

3. 3

   Inspect the wiring harness running from the PTO switch panel to the TRANS1 module. Look for chafed wires, pinched lines, or loose/corroded pins at the connector block.

4. 4

   Verify that the switch is receiving the correct reference voltage from the TRANS1 module to rule out a short to ground or short to power in the harness.

1. 1

   Power Down

   Turn off the tractor and disconnect the negative battery terminal to prevent electrical spikes.

2. 2

   Access the Switch

   Carefully pry up or unscrew the PTO control panel/armrest bezel where the 540 PTO button is housed.

3. 3

   Disconnect

   Unplug the electrical connector from the back of the faulty PTO switch.

4. 4

   Remove and Replace

   Depress the retaining tabs on the side of the switch body to push it out of the console panel. Snap the new OEM switch into place.

5. 5

   Reassemble

   Reconnect the wiring harness to the new switch and reinstall the console panel.

6. 6

   Clear Codes

   Reconnect the battery, turn the key to the ON position, and use a specialized Massey Ferguson diagnostic tool to clear the stored 06.00.13 DTC from the TRANS1 module.

7. 7

   Test Operation

   Start the tractor and engage the 540 PTO to verify the signal is recognized and the PTO clutch engages smoothly without throwing a code.
