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.
