Solution

1. Preparation

Gather tools required: OBD-II scanner, torque wrench, socket set, power steering fluid (if applicable).
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick or markings.
- If low, clean the area around the reservoir cap, remove it, and slowly add the recommended power steering fluid until it reaches the proper level.
- If fluid is contaminated (dark or gritty), perform a fluid flush and refill.

3. Check and Repair Steering Components

Inspect the steering rack and linkages:
- Remove any protective covers if necessary.
- Look for signs of wear, damage, or leaks in the steering rack; replace if faulty.
Check the steering column:
- Remove the steering wheel (if necessary) to access the column.
- Inspect for any blockages or obstructions; replace any damaged components.

4. Test Power Steering Motor

Reconnect the battery.
Power on the vehicle and check for any messages on the dashboard.
Use a multimeter to test the power steering motor for proper voltage and operation.
- If the motor is faulty, replace it as per manufacturer specifications.

5. Reassemble and Test

Reinstall any removed components and ensure all fasteners are torqued to specifications.
Test the steering feel by turning the steering wheel with the vehicle in motion in a safe environment.
