SSU 523810.01 (SSU )

Code: 523810.01



This diagnostic trouble code (DTC), SSU 523810.01, is triggered when the control unit measures too low an amperage at the connecting leads 4043/4061 for the steering valve Y49. This indicates that the circuit is open.


When this error is detected, the control unit may not be able to properly control the steering valve, leading to potential issues with steering functionality.

  • Ensure all connections are secure and free from contaminants.

Update Software:

  • Ensure that the SSU software is up-to-date. Apply any available firmware updates to improve system performance and prevent undercurrent issues.

Replace Faulty Components:

  • If any wiring, connectors, or the steering valve Y49 itself 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 electrical system can help prevent open circuits.
