PDU 002035.09 – HCC Message Missing

PDU 002035.09 (PDU 2035.09)

Code: 002035.09

Shortcode: 2035.09


This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Hitch Control Unit (HCC). This issue can arise due to communication problems, faulty wiring, or malfunctions in the HCC or PDU.


There is no immediate reaction from the control unit; however, the lack of communication may result in incomplete or missing hitch-related information on the PDU, affecting the operator’s ability to monitor and control hitch functions.


  • Inspect Communication Lines:
    • Check the wiring and connectors between the PDU and HCC for any signs of damage, loose connections, or interference.
  • Verify HCC Operation:
    • Ensure that the HCC is functioning correctly and transmitting messages as expected.
  • Update Software:
    • Update the software of both the PDU and HCC 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 HCC.
  • 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 hitch functions.
