Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and a multimeter if needed.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner instructions to retrieve any error codes. Note them down for reference.

3. Address Fault Codes

If error codes are present, refer to the vehicle's service manual to troubleshoot and fix the underlying issues.
Common issues might include faulty sensors, misfires, or exhaust leaks. Repair or replace components as necessary.

4. Check Gas Cap

Inspect the gas cap for any signs of damage or wear.
If the gas cap is loose, tighten it until you hear a click. If damaged, replace it with a new one.

5. Reset the Engine Light

Disconnect the negative terminal of the battery using a socket set.
Leave it disconnected for at least 15 minutes to ensure the computer resets.
Reconnect the negative terminal and ensure it is tight.

6. Verify Reset

Start the engine and monitor the dashboard for the check engine light.
If the light is off and no error codes are present, the reset was successful.
