Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and possibly a wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
If disconnecting the battery, have a replacement battery terminal connector if needed.

2. Using an OBD-II Scanner

Locate the OBD-II port under the dashboard on the driver's side.
Plug in the OBD-II scanner and turn the ignition key to the "On" position without starting the engine.
Follow the scanner's instructions to read and note any stored diagnostic trouble codes.
If the issues have been resolved, select the option to clear the codes/reset the check engine light from the scanner's menu.
Turn off the ignition and disconnect the scanner.

3. Disconnecting the Battery (if no scanner available)

Open the hood and locate the vehicle's battery.
Using a wrench, disconnect the negative (-) battery terminal.
Wait for at least 15 minutes to ensure all residual power is drained from the ECU.
Reconnect the negative (-) battery terminal securely.
Start the vehicle and check if the check engine light has turned off.
