Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and equipment.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s OBD-II port, usually located under the dashboard near the driver's seat.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to navigate to the "Read Codes" option and confirm any issues.

3. Clear Trouble Codes

On the OBD-II scanner, select the "Erase Codes" or "Clear Codes" option.
Confirm the action to reset the codes and the check engine light.
Wait for the scanner to indicate that the codes have been successfully cleared.

4. Disconnect Battery (Alternative Method)

If an OBD-II scanner is unavailable, you can reset the check engine light by disconnecting the battery.
Turn off the engine and open the hood.
Use a wrench to loosen the negative terminal clamp on the battery.
Remove the negative terminal and wait for at least 15 minutes.
Reattach the negative terminal and tighten it securely.
