SV1 002034.09 – SCC Message Missing

SV1 002034.09 (SV1 2034.09)

Code: 002034.09

Shortcode: 2034.09


This error code, SV1 002034.09, occurs when the Selective Control Valve Unit I (SV I) is not receiving the required messages from the SCC (Selective Control Controller). This communication failure can be due to issues in the CAN BUS network, faulty controllers, or disrupted signal transmission


When this error is detected, the SV I may not operate correctly, as it relies on the communication with the SCC for proper functionality. This can lead to malfunctions or complete inoperability of the hydraulic functions managed by the SV I.


  • Check CAN BUS Network:
    • Inspect the CAN BUS wiring and connections for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.
  • Verify SCC Operation:
    • Ensure the SCC is operating correctly and that it is sending messages as required. This may involve performing diagnostics on the SCC to identify any internal faults.
  • Inspect Signal Integrity:
    • Use diagnostic tools to check the integrity of the signals being sent between the SCC and the SV I. Ensure there are no interruptions or significant delays in communication.
  • Update Software:
    • Ensure that the software for both the SCC and the SV I is up-to-date to avoid any software-related communication issues.
  • Consult Technical Support:
    • If the issue persists after checking the above items, consult technical support for further assistance in diagnosing and resolving the communication problem.


Ensuring reliable communication within the CAN BUS network and between various controllers is crucial for the proper operation of the vehicle’s systems. Regular maintenance and updates can help prevent communication issues and improve overall system reliability.
