Description:

This diagnostic trouble code (DTC), SSU 522387.07, is triggered when, despite a steering movement being commanded, the SSU control unit fails to detect a signal from the wheel angle sensor (WAS) or receives a signal that is too low. This indicates a failure in detecting the expected steering movement.

Reaction:

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

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 Signal:

• Use diagnostic tools to verify the signal strength and accuracy from the wheel angle sensor.
• Ensure the signal meets the required thresholds.

Update Software:

• Ensure that the SSU and WAS software are up-to-date. Apply any available firmware updates to improve system performance and signal detection.

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 and sensors can help prevent signal detection failures.
• Ensuring the electrical system is properly regulated can avoid interruptions in sensor operation.
