SSU 523826.10 – B139 Steering Angle Sensor, Signals from Steering Wheel Position Sensor (B138) Not Recognized
SSU 523826.10 (SSU )
Code: 523826.10
Shortcode:
Description:
This diagnostic trouble code (DTC), SSU 523826.10, is triggered when a movement is detected by the wheel angle sensor (WAS) but not by the steering input device (SID). This indicates a discrepancy between the steering wheel input and the actual steering motion detected by the wheel angle sensor.
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) 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.
- 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.
