Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s OBD-II port (usually located under the dashboard near the steering column).
Turn the ignition to the "ON" position (do not start the engine).
Follow the scanner’s instructions to read any stored error codes.

3. Clear Error Codes

If error codes were found and addressed, use the OBD-II scanner to clear the codes.
Follow the scanner instructions to select the "Clear Codes" function.
Confirm the action and wait for the scanner to indicate that the codes have been cleared.

4. Disconnecting the Battery (if necessary)

If no scanner is available or you prefer not to use it, you can reset the check engine light by disconnecting the battery:
- Using a socket set, loosen and remove the negative terminal (-) from the battery.
- Wait for approximately 10-15 minutes to allow the vehicle's computer to reset.
- Reconnect the negative terminal and tighten securely.
