Gather tools: OBD-II scanner, vehicle owner's manual.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Connect OBD-II Scanner

Step 1: Locate the OBD-II port, typically found under the dashboard near the driver's seat.
Step 2: Plug the OBD-II scanner into the port.
Step 3: Turn the ignition key to the 'On' position without starting the engine.

3. Read and Clear Codes

Step 1: Follow the scanner's prompts to read the diagnostic trouble codes (DTCs).
Step 2: Note down any active codes for reference.
Step 3: Use the scanner's option to clear or reset the codes. This will turn off the check engine light.

4. Disconnect the Battery (Optional Method)

Step 1: If the scanner method is unavailable, disconnect the negative battery terminal using a socket wrench.
Step 2: Wait for at least 15 minutes to allow the vehicle's systems to reset.

5. Test the System

Step 1: Start the engine and observe the dashboard for the check engine light.
Step 2: Drive the vehicle for a few miles to ensure the light remains off.
