Solution
1. Preparation
  • Gather tools: socket set, wrench set, OBD-II scanner, fluid catch pan.
  • Ensure the vehicle is on a level surface and the engine is off.
  • Wear safety gloves and goggles.
2. Check Power Steering Fluid
  • Locate the power steering reservoir, typically near the engine.
  • Remove the cap and check the fluid level; it should be between the "min" and "max" marks.
  • If low, add the recommended power steering fluid (check the owner’s manual for specifications).
3. Inspect for Leaks
  • Look for any fluid spills or wet areas around the power steering pump and hoses.
  • If leaks are found, replace the affected hoses or seals as necessary.
4. Diagnose with OBD-II Scanner
  • Connect the OBD-II scanner to the vehicle’s diagnostic port.
  • Scan for any error codes related to the steering system, such as EPS faults.
  • Research any codes to determine the necessary repairs.
5. Examine Power Steering Pump
  • Start the engine and listen for any unusual noises from the power steering pump.
  • Check for vibrations or excessive heat from the pump while running.
  • If the pump is faulty, replace it with a new unit, following the manufacturer’s specifications.
6. Check Serpentine Belt
  • Inspect the serpentine belt for signs of wear, cracks, or glazing.
  • Ensure the belt is properly tensioned and aligned.
  • If damaged, replace the belt and recheck the power steering operation.
7. Inspect Steering Rack and Tie Rods
  • Lift the vehicle safely using jack stands.
  • Inspect the steering rack for any signs of leaks or damage.
  • Check the tie rod ends for play or excessive wear; replace if necessary.
