Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, power steering fluid, fluid siphon, torque wrench, power steering pressure gauge.
Ensure the vehicle is on a level surface and the engine is turned off.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir and remove the cap.
Use a fluid siphon to remove any contaminated or low fluid; inspect fluid condition (should be clear and not dark).
Refill with the appropriate type of power steering fluid as per manufacturer specifications (usually Dexron III or equivalent).
Replace the reservoir cap securely.

3. Check for Leaks

Visually inspect all power steering hoses, connections, and the steering rack for signs of fluid leaks.
If leaks are found, replace the damaged hoses or fittings as necessary.
Clean the area around leaks to monitor for new leakage.

4. Inspect and Replace Power Steering Belt

Locate the power steering belt and check for cracks, fraying, or wear.
If the belt is damaged, loosen the tensioner and remove the old belt.
Install a new belt, ensuring proper tension as per manufacturer specifications.
Torque the belt tensioner to the specified value.

5. Test Power Steering Pump Pressure

Connect the power steering pressure gauge to the pump outlet.
Start the engine and turn the steering wheel to check for proper pressure readings (should be within manufacturer specifications).
If pressure is low, replace the power steering pump.
