Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery (positive terminal first).
  • Ensure the vehicle is on a flat surface and securely supported.
2. Fluid Inspection and Top-Up
  • Locate the power steering fluid reservoir.
  • Remove the cap and check the fluid level; add manufacturer-specified power steering fluid if low.
  • Inspect the fluid for contamination (e.g., discoloration or debris).
3. Leak Repair
  • Identify the source of any fluid leaks.
  • For hose leaks:
    • Use a socket set to remove and replace damaged hoses.
    • Secure new hoses with clamps and torque to manufacturer specifications.
  • For pump leaks:
    • Disconnect the power steering pump from its mounting.
    • Replace any faulty seals or O-rings, and reassemble.
4. Electrical Component Check
  • Inspect the wiring harness and connectors for corrosion or damage.
  • Use a multimeter to test the power steering pump for proper voltage and ground.
  • Replace any faulty electrical components as necessary.
5. Steering Angle Sensor Calibration (if applicable)
  • Use an OBD-II scanner to access the steering angle sensor settings.
  • Follow manufacturer-specific procedures to recalibrate the sensor.
6. Reassembly and Final Checks
  • Reconnect the battery (negative terminal last).
  • Start the vehicle and check for immediate leaks.
  • Turn the steering wheel side to side to purge air from the system.
