SSU 523822.10 – Wheel Angle Sensor-Flow Meter Fault / Steered Motion Detected Without Steering Wheel Motion

SSU 523822.10 (SSU )

Code: 523822.10



This diagnostic trouble code (DTC), SSU 523822.10, is triggered when the Steering System Control Unit (SSU) detects steering movement from the wheel angle sensor-flow meter with little or no steering wheel movement from the steering wheel position sensor 1 or 2 (SID). This indicates a discrepancy between the detected wheel movement and the steering wheel input.


When this error is detected, the steering system may not respond correctly to steering inputs, potentially leading to inaccurate or unintended steering control.


Verify Sensor Alignment:

  • Check the alignment of the wheel angle sensor and the steering wheel position sensors (SID 1 and SID 2) to ensure they are properly aligned.

Inspect Sensor Signals:

  • Use diagnostic tools to verify the signals from the wheel angle sensor and the steering wheel position sensors.
  • Ensure that the signals are consistent and within the expected range.

Check for Mechanical Issues:

  • Inspect the steering mechanism for any signs of looseness or mechanical play that could cause discrepancies in sensor readings.

Update Software:

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

Replace Faulty Components:

  • If any of the sensors or related 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 steering system can help prevent discrepancies between sensor readings.
  • Ensuring accurate sensor alignment and calibration is crucial for reliable steering performance.
