SSU 523824.05 – B138 Steering Wheel Position Sensor, Current in Channel 2 Too Low

SSU 523824.05 (SSU )

Code: 523824.05

Shortcode:

Description:

This diagnostic trouble code (DTC), SSU 523824.05, is generated when less than 4 mA flow to the steering input device SID 2 for longer than 320 milliseconds. This indicates a low current condition in channel 2 of the steering wheel position sensor.

Reaction:

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

Recommendations:

Inspect Circuit for Open Connections:

  • Check the wiring and connectors of channel 2 for signs of an open circuit.
  • Use diagnostic tools to identify and locate any breaks or discontinuities in the circuit.

Verify Connections:

  • Inspect the connections related to SID 2 for damage, loose connections, or corrosion.
  • Ensure all connections are secure and free from contaminants.

Check Power Supply:

  • Verify that the power supply to channel 2 is providing adequate current.
  • Ensure that the current does not fall below 4 mA.

Update Software:

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

Replace Faulty Components:

  • If any wiring, connectors, or SID 2 itself 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 electrical system can help prevent open circuits.
  • Ensuring the wiring and connectors are in good condition is crucial for reliable operation of the control unit and steering system.
