 I understand that. It doesn't work like that anymore. If you've got a check engine light on, they could plug an inexpensive scan tool in it and tell you if you've got a bad oxygen sensor or something like that. But as far as getting any data or being able to download new software into the system, you've got to use vehicle-specific equipment. And they give that stuff away, don't they, Marty? It's cheap. They just give it to you.
