SSU 523824.06 – B138 Steering Wheel Position Sensor, Current in Channel 2 Too High
SSU 523824.06 (SSU )
Code: 523824.06
Shortcode:
Description:
This diagnostic trouble code (DTC), SSU 523824.06, is generated when more than 20 mA flow to the steering input device SID 2 for longer than 320 milliseconds. This indicates an overcurrent 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 Shorts:
- Check the wiring and connectors of channel 2 for signs of short circuits.
- Use diagnostic tools to identify and locate any short circuits 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 not providing excessive current.
- Ensure that the current does not exceed 20 mA.
Update Software:
- Ensure that the SSU software is up-to-date. Apply any available firmware updates to improve system performance and prevent overcurrent 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 short circuits.
- Ensuring the wiring and connectors are in good condition is crucial for reliable operation of the control unit and steering system.
