Solution

1. Preparation

Gather tools such as an OBD-II scanner and a wrench for battery terminal removal.
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition to the "ON" position (do not start the engine).
Follow the scanner's prompts to read and clear trouble codes, selecting the option to erase codes.

3. Battery Disconnect Method

Open the hood and locate the battery.
Using a wrench, loosen the negative (-) battery terminal clamp and remove it from the battery post.
Wait for at least 10 minutes to allow the vehicle's systems to reset.
Reattach the negative battery terminal and tighten the clamp securely.

4. Verification

Start the engine and observe the dashboard for the check engine light.
If the light remains off, perform a test drive to ensure normal operation.
After the drive, recheck with the OBD-II scanner to confirm no new codes have appeared.
