Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, standard socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Check and Top Up Power Steering Fluid

Locate the power steering fluid reservoir (consult the owner’s manual for exact location).
Remove the cap and check the fluid level against the dipstick or marking.
If low, use the manufacturer-recommended power steering fluid to top it up.
Replace the cap securely.

3. Inspect Steering Components

Use the socket set to remove any covers obstructing access to the steering components.
Visually inspect the steering rack, tie rods, and any joints for wear or damage.
If any components are damaged, replace them with OEM parts.

4. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all four tires.
Inflate any tires that are below the recommended pressure, typically found on the driver's side door jamb.
Recheck the pressure after inflation to ensure it is correct.

5. Perform a Steering Angle Calibration (if applicable)

Reconnect the battery and turn on the vehicle.
Use the vehicle’s software interface to access the steering angle calibration feature.
Follow the prompts to recalibrate the steering system, ensuring it functions correctly.
