As I understand it, no. ODBII is a read-only data port that surfaces information about the state of your car. I don't believe it lets you enter commands.
That being said, there have been man vulnerabilities in car software which is all proprietary and hasn't undergone any public review, so I guess it is possible.
- Peroni 14y agoI don't believe it lets you enter commands. They can but they are usually pre-programmed commands set by the manufacturer. Most electronic elements to a vehicle can be controlled with the correct manufacturer equipment and software that most branded dealerships have.
- UnoriginalGuy 14y agoOBD-II isn't completely read-only. I mean at the very least it is used to control car keys. I know that because MANY cars are being stolen locally via the keys being reset using the OBD-II port. They target particular models of a car. They drive around, find that car/model, then use a slim jim to open the door, plug into the OBD-II port, and reset the key to one in their possession - then they can just drive the car away as if it was their own.
