1. 1

   Restart the tractor engine to verify if the active Diagnostic Trouble Code reappears or if it was a temporary communication glitch

2. 2

   Press the select switch on the CommandCenter display to acknowledge the code and see if the display returns to normal mode

3. 3

   While seated in the operator's seat, cycle the front PTO switch off and on

4. 4

   Visually inspect the front PTO switch and its related wiring circuit for any obvious signs of damage, debris, or loose connections

5. 5

   Check the Operator Interface Control (OIC) software version to ensure it is up to date

1. 1

   Confirm fault

   Restart the tractor and cycle the front PTO switch to confirm the fault is a hard, returning fault.

2. 2

   Inspect wiring

   Inspect the wiring harness and connectors running between the front PTO switch and the Cab Module (AIC) or Arm Rest Module (AIC) for shorts, opens, or corrosion.

3. 3

   Repair wiring

   Repair or replace any damaged wiring components found during the inspection.

4. 4

   Replace switch

   If the wiring is intact and the CAN BUS messages remain implausible, replace the faulty Front PTO Switch.

5. 5

   Update software

   Update the OIC control software if an update is available, as outdated software can cause implausible signal readings.

6. 6

   Clear codes and test

   Clear the diagnostic trouble codes and test the front PTO system to ensure proper operation. If the code returns, official documentation recommends having a John Deere dealer perform further module diagnostics.
