Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, torque wrench, power steering fluid, multimeter.
Park the vehicle on a level surface and turn off the engine. Allow the vehicle to cool before starting work.

2. Inspect Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Check the fluid level; it should be within the recommended range.
3. If low, top off with the manufacturer's recommended power steering fluid.
4. Inspect the fluid condition; if it appears dirty or contaminated, proceed to replace it.

3. Check for Leaks

Sub-steps:
1. Visually inspect power steering hoses and connections for signs of leakage.
2. Use a fluid catch pan to collect any leaking fluid.
3. If leaks are found, replace the damaged hoses or fittings.

4. Test Power Steering Pump

Sub-steps:
1. Disconnect the power steering pump electrical connector.
2. Use a multimeter to check for voltage at the pump when the ignition is on.
3. If voltage is present but the pump is not functioning, replace the power steering pump.
4. If no voltage is detected, inspect wiring and connections leading to the pump.

5. Inspect Steering Rack

Sub-steps:
1. Check the steering rack for any signs of damage or wear.
2. If the steering rack is leaking or damaged, it will need to be replaced.
3. Follow manufacturer specifications for torque settings when reassembling components.
