Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, socket set, power steering fluid, multimeter, torque wrench, pressure gauge.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening any components.

2. Fluid Check and Replacement

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; top off with the manufacturer-recommended power steering fluid if low.
3. If the fluid is dark or contaminated, drain the old fluid from the reservoir and lines.
4. Replace it with fresh power steering fluid according to the specifications in the owner’s manual.

3. Electrical System Inspection

Sub-steps:
1. Inspect the wiring harness connected to the power steering control module for damage or corrosion.
2. Use a multimeter to check for continuity and voltage at the power steering control module.
3. Repair or replace any damaged connectors or wiring as necessary.

4. Power Steering Pump Testing

Sub-steps:
1. Disconnect the power steering pump from the serpentine belt.
2. Attach a pressure gauge to the pump outlet.
3. Start the engine and check the pressure readings; they should meet manufacturer specifications.
4. If pressure is low, replace the power steering pump.

5. Steering Rack Inspection

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Inspect the steering rack for leaks, play, or physical damage.
3. If issues are found, replace the steering rack assembly following manufacturer-specific torque values for bolts.
