Description:

This error code is generated when the OIC control software detects an open circuit to the operator presence switch. A replacement value is transmitted, generating this diagnostic trouble code in the PTF control software. This fault also generates a diagnostic trouble code in the OIC control software, which takes priority.

Reaction:

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

Recommendations:

• Inspect Switch Circuit:
  • Check for an open circuit in the wiring to the operator presence switch.
  • Repair or replace any damaged or disconnected wires.
• Test the Switch:
  • Verify the functionality of the operator presence 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 operator presence switch and its circuit can prevent open circuit issues and ensure reliable operation.
