Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard.
Turn the ignition key to the "ON" position (do not start the engine) and power on the scanner.
Follow the scanner's prompts to retrieve and record any error codes.

Navigate to the “Clear Codes” or “Erase Codes” option on the OBD-II scanner.
Confirm the action to clear the stored error codes and reset the check engine light.

4. Battery Disconnection Method (if applicable)

Turn off the ignition and locate the vehicle's battery.
Use a socket set to loosen the negative battery terminal clamp.
Carefully remove the negative terminal from the battery post.
Wait for at least 15 minutes to allow the vehicle's computer to reset.
Reattach the negative battery terminal and tighten the clamp securely.

5. Verify Reset

Start the engine and check if the check engine light is off.
If the light remains on, recheck error codes with the OBD-II scanner to identify any unresolved issues.
