For anyone like OP here, get a BT device that plugs in the computer. Then get the Android app, free but worth paying for if you want more bells and whistles. I had a hacked version but was so pleased I bought it to always have on future phones.
You can see and lookup engine codes, see what’s wrong with your car. It kind of a trip what all it does. I’m not gearhead, but when the car acts up, I can get a clue. Also clears annoying gremlin lights.
