What type of vehicle? You can get an OBD2 scan tool off Amazon for around $30 now. Granted, it doesn’t go as in-depth as an Autel or Innova, but it will easily tell you the issue and also let you clear the code/light. Most people don’t need and likely would never fully use the capabilities of the expensive units anyway.
I’ve been deeply involved in/on the automotive side for over twenty years, so if you ever want to shoot me a question or ask for advice with anything, don’t hesitate. I got into the endless hobby when my grandfather raced dirt tracks and I’ve never thought of getting away from it.
