Description:

This diagnostic trouble code (DTC), SSU 001807.05, is generated when less than 4 mA flow to the steering wheel position sensor SID 1 for longer than 320 milliseconds. This indicates an open circuit or insufficient current supply to the sensor.

Reaction:

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

Recommendations:

Inspect Power Supply:

• Check the power supply to the steering wheel position sensor SID 1 to ensure proper current flow.
• Ensure that the current does not drop below 4 mA.

Verify Sensor Connections:

• Inspect the wiring and connectors related to the steering wheel position sensor SID 1 for signs of damage, loose connections, or corrosion.
• Ensure all connections are secure and free from contaminants.

Check for Open Circuit:

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

Update Software:

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

Replace Faulty Components:

• If the steering wheel position sensor SID 1 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 current conditions.
• Ensuring the electrical system is properly regulated can avoid interruptions in sensor operation.
