Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is on a level surface with the ignition off.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and remove the cap.
- Check the fluid level; if low, add manufacturer-recommended power steering fluid.
- If fluid is dirty or contaminated, drain the system using a siphon.
- Flush the power steering system with new fluid and refill to the appropriate level.

3. Repair or Replace Steering Components

Sub-steps:
- If any components (steering rack, pump, or hoses) show signs of wear or damage, remove and replace them.
- Use a socket set to detach the steering rack from the vehicle.
- Install the new rack, ensuring all bolts are torqued to the manufacturer's specifications.
- Reconnect all hoses and electrical connections securely.

4. Recalibrate Steering Angle Sensor

Sub-steps:
- Using a diagnostic tool, access the steering angle sensor calibration function.
- Follow the on-screen prompts to complete the calibration process.
- Clear any existing error codes from the system.

5. Final Assembly and Testing

Sub-steps:
- Reconnect the vehicle’s battery.
- Start the vehicle and turn the steering wheel to check for any abnormal noises or resistance.
- Test drive the vehicle to ensure proper steering function and verify that no warning lights are illuminated.
