2. Address Low Fluid Level

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the dipstick.
3. If low, add the appropriate power steering fluid as specified in the owner's manual.
4. Inspect for leaks around the reservoir and hoses; repair any leaks if found.

3. Inspect and Replace Steering Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect the steering rack and linkages for damage or wear.
3. If damage is found, remove the damaged component using the socket set.
4. Install the new steering rack or components, ensuring they are torqued to the manufacturer specifications.

4. Check Electrical Connections

Sub-steps:
1. Locate the power steering control module.
2. Disconnect the electrical connectors and inspect for corrosion or damage.
3. Clean the connectors with electronic cleaner and reconnect securely.

5. Perform Steering Angle Sensor Calibration

Sub-steps:
1. Connect the OBD-II scanner and navigate to the steering angle sensor calibration function.
2. Follow the prompts to reset and calibrate the steering angle sensor as per the scanner instructions.
3. Turn the steering wheel from lock to lock to finalize calibration.
