SSU 523824.10 – B138 Steering Wheel Position Sensor, Voltage in Channel 1 and Channel 2 Not in Correct Ratio

SSU 523824.10 (SSU )

Code: 523824.10

Shortcode:

Description:

This diagnostic trouble code (DTC), SSU 523824.10, is triggered when the values read by the steering wheel position sensors SID 1 and SID 2 differ by more than 20. This indicates a problem in steering input device SID 2.

Reaction:

When this error is detected, the steering system may not function correctly, potentially leading to inaccurate steering inputs and compromised vehicle control.

Recommendations:

Verify Sensor Calibration:

  • Ensure that both steering wheel position sensors SID 1 and SID 2 are correctly calibrated.

Inspect Sensor Alignment:

  • Check the physical alignment of the steering wheel position sensors to ensure they are correctly positioned.

Verify Sensor Signals:

  • Use diagnostic tools to verify that the voltage ratio between channel 1 and channel 2 meets the required specifications.
  • Ensure that the signals from both sensors are consistent and within the expected range.

Update Software:

  • Ensure that the SSU software is up-to-date. Apply any available firmware updates to improve system performance and compatibility.

Replace Faulty Components:

  • If either of the steering wheel position 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 components can help prevent voltage ratio discrepancies.
  • Ensuring both sensors are functioning correctly is crucial for accurate steering input and vehicle control.
