Description:

This diagnostic trouble code is generated when the OIC control software detects an open circuit to the front PTO switch. A transmitted replacement value generates this diagnostic trouble code in the PTF control software. In its active state, this fault also generates a diagnostic trouble code in the OIC control software. The OIC diagnostic trouble codes take priority.

Reaction:

When this code is detected, the control software may exhibit limited or no functionality.

Recommendations:

• Inspect PTO Switch Circuit:
  • Check for an open circuit in the wiring to the front PTO switch.
  • Repair or replace any damaged or disconnected wires.
• Test the PTO Switch:
  • Verify the functionality of the front PTO switch using diagnostic tools.
  • Replace the switch if it is found to be faulty.
• Check Connectors:
  • Ensure that all connectors are properly seated and free of corrosion.
  • Clean or replace connectors as needed.

Note:

Regular inspection and maintenance of the front PTO switch and its circuit can prevent open circuit issues and ensure reliable operation.
