PDU 002240.09 – TEC Message Missing

PDU 002240.09 (PDU 2240.09)

Code: 002240.09

Shortcode: 2240.09


This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Tractor Equipment Control Unit (TEC). This can result from communication problems, wiring issues, or faults within the TEC or PDU.


There is no immediate reaction from the control unit; however, the lack of communication can lead to incomplete or missing tractor equipment-related information on the PDU, affecting the operator’s ability to monitor and control various equipment functions.


  • Inspect Communication Lines:
    • Check the wiring and connectors between the PDU and TEC for any signs of damage, loose connections, or interference.
  • Verify TEC Operation:
    • Ensure that the TEC is functioning correctly and transmitting messages as expected.
  • Update Software:
    • Update the software of both the PDU and TEC to the latest versions to ensure compatibility and proper communication protocols.
  • Reset the System:
    • Perform a system reset to reestablish communication between the PDU and TEC.
  • Consult Technical Support:
    • If the communication issue persists, contact technical support for further diagnostics and solutions.


Regular maintenance of communication lines and software updates can prevent such issues and ensure reliable operation of tractor equipment functions.
