Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, power steering fluid, multimeter, fluid catch pan.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the battery before starting any electrical work.

2. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir (typically near the engine).
2. Remove the cap and check the fluid level against the markings.
3. If low, add the appropriate type of power steering fluid as specified in the owner's manual.
4. Replace the cap securely and check for leaks.

3. Inspect Power Steering System Components

Sub-steps:
1. Visually inspect all power steering hoses for cracks or leaks.
2. Tighten any loose clamps or connections.
3. Check the power steering pump for signs of wear or damage.
4. If necessary, replace any faulty hoses or the power steering pump.

4. Test Power Steering Pump

Sub-steps:
1. Reconnect the battery and start the engine.
2. Use a multimeter to measure the voltage at the power steering pump's connector.
3. If voltage is present but the pump does not operate, replace the pump.
4. If no voltage is present, trace wiring back to the steering control module.

5. Inspect Steering Rack and Tie Rods

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Inspect the steering rack for leaks and physical damage.
3. Check tie rods for end play by moving them side to side.
4. If wear is present, replace the steering rack or tie rods as necessary.
