Solution

1. Preparation

Tools Required: OBD-II scanner, ratchet and socket set, multimeter (if needed for electrical diagnostics).
Ensure the vehicle is parked on a flat surface, and the engine is off and cool.

2. Use OBD-II Scanner

Plug the OBD-II scanner into the vehicle's OBD-II port, typically located under the dashboard near the driver's seat.
Turn the ignition key to the "On" position without starting the engine.
Follow the scanner's instructions to access the diagnostic menu and select "Read Codes."
Note any trouble codes and clear them by selecting the "Clear Codes" option on the scanner.

3. Disconnect Battery Terminal

Using the appropriate socket, loosen the nut on the negative battery terminal.
Remove the negative terminal from the battery post and ensure it does not touch the battery for at least 10 minutes.
Reconnect the negative battery terminal and tighten the nut securely.

4. Verify the Reset

Start the engine and check if the check engine light is still illuminated.
If the light is off, conduct a test drive to ensure the vehicle operates without issues.
