Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, and possibly a multimeter.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to reset the system.

2. Reconnect the Battery

Reconnect the negative battery terminal securely after waiting for at least 10-15 minutes.
Tighten the terminal using a socket wrench to ensure a good connection.

3. Reset the Power Steering System

Turn the ignition key to the "ON" position without starting the engine.
Wait for about 5 seconds, then turn the steering wheel fully to the left and right, stopping at each end for a few seconds.
Start the engine and allow it to idle for a minute, which helps the system recalibrate.

4. Check for DTCs

Reconnect the OBD-II scanner and check for any power steering-related trouble codes.
Clear any codes that may be present, and turn off the ignition.

5. Test Drive

Take the vehicle for a short test drive to ensure the power steering assist is functioning normally.
Monitor the steering responsiveness and check for any warning lights.
