PDU 002030.09 – VLC Message Missing

PDU 002030.09 (PDU 2030.09)

Code: 002030.09

Shortcode: 2030.09


This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Vehicle Load Center Control Unit (VLC). This can be due to communication issues, wiring problems, or faults within the VLC or PDU.


There is no immediate reaction from the control unit; however, the lack of communication can lead to incomplete or missing load center information on the PDU, affecting the operator’s ability to monitor and manage vehicle loads.


  • Inspect Communication Lines:
    • Check the wiring and connectors between the PDU and VLC for any signs of damage, loose connections, or interference.
  • Verify VLC Operation:
    • Ensure that the VLC is functioning correctly and transmitting messages as expected.
  • Update Software:
    • Update the software of both the PDU and VLC 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 VLC.
  • Consult Technical Support:
    • If the communication issue persists, contact technical support for further diagnostics and solutions.


Maintaining secure and clean connections between the PDU and VLC, along with regular software updates, is crucial for reliable communication and vehicle load management.
