Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir (typically found near the engine).
Remove the cap and check the fluid level; it should be between the "Min" and "Max" marks.
If low, add the recommended power steering fluid until the correct level is reached.

3. Check for Leaks

Inspect hoses, connections, and the steering rack for any signs of fluid leaks.
If leaks are found, replace the damaged hoses or seals as necessary.

4. Test and Replace Steering Angle Sensor (if necessary)

Locate the steering angle sensor, typically mounted on the steering column.
Use a multimeter to check the sensor's output; refer to the vehicle's service manual for specific resistance values.
If the sensor is faulty, disconnect it and replace it with a new unit, ensuring proper alignment and calibration.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes related to the steering system.

6. Test Drive the Vehicle

Take the vehicle for a test drive to ensure the warning light does not re-illuminate and that steering feels normal.
