Description:

This diagnostic trouble code (DTC), SSU 001807.02, is triggered when false signals are sent to the SSU control unit during the calibration of steering input devices SID 1 or SID 2. This indicates a calibration error in the steering wheel position sensor.

Reaction:

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

Recommendations:

Verify Calibration Procedure:

• Ensure that the correct calibration procedure is being followed for SID 1 and SID 2. Refer to the manufacturer’s guidelines for proper calibration steps.

Inspect Steering Wheel Position Sensor:

• Check the steering wheel position sensor for any signs of damage or malfunction.
• Ensure the sensor is securely mounted and properly connected.

Check for Interference:

• Ensure that there are no sources of electrical interference near the steering wheel position sensor that could be causing false signals.

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 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 calibration errors.
• Accurate calibration of steering input devices is crucial for reliable steering performance.
