Remove the power steering fluid reservoir cap.
Inspect fluid level; add fluid if low (use manufacturer-recommended fluid).
Check for signs of contamination (e.g., foam or debris).

3. Inspect for Leaks

Visually examine all power steering hoses and connections.
Look for wet spots or drips under the vehicle.
Tighten any loose connections or replace damaged hoses as needed.

4. Scan for Error Codes

Connect an OBD-II scanner to the vehicle’s diagnostic port.
Record any trouble codes related to the steering system.
Address any faults indicated, such as replacing faulty sensors or electrical components.

5. Inspect Steering Components

Raise the vehicle and secure it on jack stands.
Check the steering rack and pinion for play or damage.
Inspect tie rods and ball joints for wear; replace if necessary.

6. Test Electric Power Steering Motor

Reconnect the battery and start the vehicle.
Monitor the operation of the electric power steering motor.
If the motor is not functioning, check the wiring, connectors, and the motor itself for faults.
