Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid catch pan, multimeter, and safety gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "min" and "max" marks.
If low, use the appropriate power steering fluid (check owner's manual for specifications) to refill to the correct level.
Replace the cap securely.

3. Inspect and Repair Steering Components

If the fluid is fine, visually inspect power steering hoses and connections for leaks or damage.
If leaks are found, replace the damaged hoses or fittings.
If the power steering pump is faulty, use a socket set to remove the pump from its mounting, disconnect the hoses, and install a new pump.

4. Electrical System Check (for Electric Power Steering)

Reconnect the negative battery terminal.
Use a multimeter to check the voltage at the power steering motor connector.
If voltage is present and the motor does not operate, replace the power steering motor.

5. Test Drive

Start the vehicle and check for any warning lights.
Test the steering for responsiveness and ease of maneuvering.
Ensure that there are no additional noises or issues when turning the steering wheel.
