Solution

1. Preparation

Gather necessary tools, including an OBD-II scanner and a wrench for battery removal.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Use an OBD-II Scanner

Locate the OBD-II port, typically found under the dashboard, near the steering column.
Connect the OBD-II scanner to the port.
Turn on the vehicle’s ignition (do not start the engine).
Follow the scanner instructions to read and record any error codes.
Clear the codes using the scanner's "Erase" or "Clear Codes" function.

3. Disconnect the Battery

Turn off the ignition and ensure all accessories are off.
Using a wrench, loosen the negative (-) terminal of the battery and remove the cable.
Wait for approximately 10-15 minutes to allow the vehicle's ECU to reset.
Reattach the negative terminal and tighten it securely.

4. Final Check

Start the vehicle and observe the dashboard for the check engine light.
Drive the vehicle for a short distance to ensure the light does not return.
