SSU 523824.04 – B138 Steering Wheel Position Sensor, Supply Voltage in Channel 2 Too Low

SSU 523824.04 (SSU )

Code: 523824.04

Shortcode:

Description:

This diagnostic trouble code (DTC), SSU 523824.04, is triggered when the power supply for the steering input device SID 2 falls below 4.75 volts for longer than 320 milliseconds. This indicates a low voltage condition, potentially due to an open circuit 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 Power Supply:

  • Check the power supply to the steering input device SID 2 for proper voltage regulation.
  • Ensure that the voltage does not fall below 4.75 volts.

Verify Sensor Connections:

  • Inspect the wiring and connectors related to channel 2 of the steering input device for signs of damage, loose connections, or corrosion.
  • Ensure all connections are secure and free from contaminants.

Check for Open Circuits:

  • Use diagnostic tools to check for continuity in the power supply circuit to ensure there are no open connections.

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 the steering input device SID 2 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 low voltage conditions.
  • Ensuring the electrical system is properly regulated can avoid interruptions in sensor operation.
