Description:

This diagnostic trouble code (DTC), SSU 523826.02, is triggered when the wheel angle sensor (WAS) sends false signals to the SSU control unit during calibration. This indicates an issue with the accuracy of the signals from the sensor during the calibration process.

Reaction:

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

Recommendations:

Inspect Wheel Angle Sensor:

• Check the wheel angle sensor (WAS) for proper operation and signal transmission.
• Ensure the sensor is securely mounted and properly connected.

Verify Sensor Signals:

• Use diagnostic tools to verify the signals from the wheel angle sensor during calibration.
• Ensure that the signals are accurate and within the expected range.

Perform Calibration:

• Recalibrate the steering system following the correct procedure to ensure accurate alignment and configuration of the sensor.
• Follow the manufacturer’s guidelines for the calibration process.

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 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.

Note:

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