SSU 001865.09 – ELX Message Missing

SSU 001865.09 (SSU 1865.09)

Code: 001865.09

Shortcode: 1865.09


This diagnostic trouble code (DTC), SSU 001865.09, is triggered when the Steering System Control Unit (SSU) detects that the Vehicle Load Center (VLC) ELX output 2 message is not available on the CAN Bus. This indicates a communication issue with the VLC.


When this error is detected, the steering system may not receive necessary information from the VLC, potentially leading to operational issues.


Verify CAN Bus Communication:

  • Inspect the CAN Bus wiring and connectors for any signs of damage, loose connections, or corrosion.
  • Use diagnostic tools to check for continuity and proper voltage levels in the CAN Bus lines.

Check VLC:

  • Ensure that the Vehicle Load Center (VLC) is functioning properly and transmitting the ELX output 2 message correctly.
  • Verify that the VLC is correctly configured and operating.

Update Software:

  • Ensure that the SSU and VLC software are up-to-date. Apply any available firmware updates to improve system performance and communication protocols.

Replace Faulty Components:

  • If the VLC or related CAN Bus components are found to be defective, replace them with new, genuine parts.

Consult Technical Support:

  • If the error persists after performing the above steps, consult technical support or the manufacturer for further assistance.


  • Regular maintenance and inspection of the CAN Bus network and connected components can help prevent communication issues.
  • Keeping the system firmware up-to-date ensures compatibility and reliability of the vehicle’s communication systems.
