Description:

This operator information (diagnostic trouble code) is generated if the front PTO is switched on when starting the engine or turning on the ignition. If the diagnostic trouble code is generated although the front PTO was not on while starting the engine, the switch circuit must be checked.

Reaction:

The control software informs the operator that the front PTO was on during engine start, potentially affecting normal operation.

Recommendations:

• Inspect Front PTO Switch:
  • Check if the front PTO switch is in the “on” position during engine start.
  • Ensure that the switch is functioning correctly.
• Verify Switch Circuit:
  • Inspect the wiring and connections of the front PTO switch for any faults or loose connections.
  • Repair or replace any defective components.
• Check for False Signals:
  • Ensure that there are no false signals being sent to the control software indicating the PTO is on.

Note:

Ensuring the front PTO switch and its circuit are in proper working condition is essential for accurate diagnostics and preventing unintended PTO engagement during engine start.
