The service engine soon light often indicates liquids need topping off or it’s time for an oil change. You can, if you’re confident, service these yourself.
If your liquids are topped off, and you’ve recently taken your car to a mechanic, but your light is still on, you may need to reset the light with a diagnostic scanner or a combination of codes for your vehicle. You can look in your owner’s manual for the specific code to reset your service engine soon light.
