Description:

This diagnostic trouble code (DTC), SSU 523822.02, is triggered when the Steering System Control Unit (SSU) detects that the wheel angle sensor-flow meter direction is incorrect after the manual steering portion of the SSU calibration procedure. This indicates a misalignment or incorrect configuration of the sensor and flow meter.

Reaction:

When this error is detected, the steering system may not calibrate correctly, leading to inaccurate steering control and potential safety issues.

Recommendations:

Verify Sensor and Flow Meter Alignment:

• Check the alignment of the wheel angle sensor and flow meter to ensure they are correctly positioned.
• Ensure that the sensor and flow meter are properly configured according to the manufacturer’s guidelines.

Perform Calibration:

• Recalibrate the steering system following the correct procedure to ensure accurate alignment and configuration of the sensor and flow meter.
• Ensure that the calibration process is followed precisely to avoid discrepancies.

Update Software:

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

Replace Faulty Components:

• If the wheel angle sensor or flow meter 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.

Note:

• Regular maintenance and inspection of the steering system can help prevent calibration faults.
• Ensuring proper alignment and accurate calibration is crucial for reliable steering performance.
