SCO 002000.09 (SCO 2000.09)

Code: 002000.09

Shortcode: 2000.09


This error code, SCO 002000.09, is generated when a data transfer problem occurs between the ECU control unit and the SCO control software. The reception of one, several, or all of the CAN messages expected by the ECU control unit is intermittent or non-existent. This indicates a problem in the CAN BUS or in the transmitting control software, potentially due to a loose wire or faulty components.


When this fault is detected, the control software may have limited functionality or may cease to function altogether.


  • Inspect CAN BUS Wiring:
    • Check all CAN BUS wiring for signs of damage, loose connections, or corrosion. Secure and repair any issues found.
  • Verify ECU Control Unit:
    • Ensure that the ECU control unit is functioning correctly. Recalibrate or replace the unit if necessary.
  • Check CAN BUS Communication:
    • Test the CAN BUS network for proper communication and address any faults detected.
  • Consult Technical Support:
    • If the issue persists, consult technical support for further diagnostics and assistance.


Intermittent Issues:

  • Intermittent reception can be difficult to diagnose. Regular monitoring and thorough inspection of the CAN BUS system are recommended.
