1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the engine and ensure all accessories are off.
Gather tools and equipment needed for the reset.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s OBD-II port (usually located under the dashboard near the steering wheel).
Turn on the vehicle's ignition without starting the engine (position II).
Follow the scanner’s instructions to read and clear the diagnostic trouble codes.
- Navigate to the 'Read Codes' section and note any fault codes.
- Navigate to the 'Clear Codes' section and confirm the action to reset.

3. Disconnect the Battery (Alternative Method)

If an OBD-II scanner is unavailable, you can reset the CEL by disconnecting the battery.
- Use a socket set to remove the negative terminal of the battery.
- Leave it disconnected for at least 15 minutes to allow the vehicle’s computer to reset.
- Reconnect the negative terminal and tighten it securely.

4. Test Drive

Start the engine and allow it to run for a few minutes.
Take the vehicle for a short test drive to ensure the check engine light remains off.
