Description:

This diagnostic trouble code (DTC), SSU 523822.14, is triggered when the Steering System Control Unit (SSU) detects that the steering wheel position sensor 1 or 2 (SID) shows movement (at least 90° rotation) with little or no corresponding movement from the wheel angle sensor-flow meter. This indicates a discrepancy between the steering wheel input and the actual steering motion.

Reaction:

When this error is detected, the steering system may not respond accurately to steering inputs, potentially leading to issues with vehicle control and safety.

Recommendations:

Inspect Steering Wheel Position Sensors:

• Check the steering wheel position sensors (SID 1 and SID 2) for proper operation and signal transmission.
• Ensure the sensors are securely mounted and properly connected.

Verify Sensor Signals:

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

Check for Mechanical Issues:

• Inspect the steering mechanism for any signs of looseness, wear, or mechanical play that could cause discrepancies in sensor readings.
• Tighten or replace any worn components as necessary.

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.

Note:

• 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.
