1. Gather your tools. You will need a scan tool or code reader, a flashlight, and a pair of gloves.
2. Park your vehicle in a safe location and turn off the engine.
3. Open the hood of your vehicle.
4. Locate the diagnostic port. It is usually located under the dashboard on the driver's side.
5. Connect the scan tool or code reader to the diagnostic port.
6. Turn on the ignition, but do not start the engine.
7. Follow the prompts on the scan tool or code reader to retrieve and clear the diagnostic trouble codes (DTCs).
8. Once the DTCs have been cleared, turn off the ignition and disconnect the scan tool or code reader.
9. Start the engine and verify that the check engine light is off.
If the check engine light remains on after following these steps, you may need to take your vehicle to a qualified mechanic for further diagnosis and repair.
Important Note: Clearing the diagnostic trouble codes does not fix the underlying problem that caused the light to illuminate in the first place. It is crucial to address the root cause of the issue to ensure the proper functioning of your vehicle and prevent further damage.
