If you drive an older Tesla, you may find the OBD port under the dashboard on the driver’s side.
Newer Tesla Model 3 and Model Y vehicles have a location where you can use an adapter with a typical diagnostic tool to learn more about what’s happening with your car. You can use a Tesla app to display this live data but you might not see as much data as you’re used to viewing.
Teslas offer some self-diagnostic capabilities—but Tesla is also very committed to security. This means that your ability to monitor and diagnose your vehicle is fairly limited compared to other models.
The original purpose of OBD ports was to test adherence to emissions standards. Since Teslas are electric, this isn’t strictly necessary. Tesla received a special exemption from the OBD requirement.
