SSU 523822.05 – Wheel Angle Sensor-Flow Meter Current Low

SSU 523822.05 (SSU )

Code: 523822.05



This diagnostic trouble code (DTC), SSU 523822.05, is triggered when the Steering System Control Unit (SSU) detects that the wheel angle sensor-flow meter return current is open. This indicates a low current condition in the return circuit of the wheel angle sensor-flow meter.


When this error is detected, the steering system may not function correctly, potentially leading to inaccurate steering angle readings and compromised vehicle control.


Inspect Circuit for Open Connections:

  • Check the wiring and connectors of the wheel angle sensor-flow meter return circuit for signs of an open circuit.
  • Use diagnostic tools to identify and locate any breaks or discontinuities in the circuit.

Verify Connections:

  • Inspect the connections related to the wheel angle sensor-flow meter for damage, loose connections, or corrosion.
  • 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 low current issues.

Replace Faulty Components:

  • If any wiring, connectors, or the wheel angle sensor-flow meter 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.
  • Ensuring the wiring and connectors are in good condition is crucial for reliable operation of the control unit and steering system.
