Tesla OBD – What Are The Options?

If you know anything about cars and electronics then you might be wondering if Tesla has OBD (On-board Diagnostic)?

After all, access to the OBD port gives you a lot of data about the car and enables you to learn, diagnose and fix things that you otherwise would have no chance with.

Interestingly, OBD became a standard way back in 1988 with an SAE recommendation for all new passenger vehicles, light, and medium-duty vehicles. It was put in place to help measure fuel and exhaust system-related values.

Does Tesla Have OBD-II?

Given that all vehicles have OBD, it is no surprise that Tesla also has it. In fact, Tesla has the latest standard called OBD2 or OBD-II, which became standard in 1995.

On each of Tesla’s models, there is an OBD2 port under the dash which is accessible with the right tools and adapters.

Tesla OBD Port Location (For Each Model)

There is no standard position for the OBD port on a Tesla, however, I have highlighted the location on each Tesla model below:

Model Y / Model 3

The Tesla Model Y and Model 3 have made the OBD port easier to access by placing it on the door side of the footwell on the driver’s side of the vehicle. You can see an example from the Tesla owners manual in the image below.

Model 3 – Alternative Location

I have also seen confusing information about the Model 3 connector, so here is some extra information.

If you cannot find the OBD connector under the dash, then there appears to be a Tesla Model 3 diagnostic cable behind the center console on the bottom (in the back seat area). It is not an open connector for attaching diagnostics, so be far more cautious about playing with this one. Below is a video from a company that sells OBD adapters with more information. I do not recommend this in any way shape or form.

Model S / Model X

In the Tesla Model S, the OBD-II connecter is located below the main screen. It is relatively simple to get to it, you just have to pull down on the cubby below it to release the clips. The video below shows you how to do it

Tesla OBD2 Adapters

If you want to connect to the OBD-II port you are going to need a specific adapter. The majority are designed to plug into the Onboard Diagnostics and be accessed via bluetooth on your phone. You can then make use of various Apps to view the data that is available.

Just be aware that you need to get the right adapter for your Model Tesla as they have changed over the years and with each model.

OHP have developed a handy ODB2 adapter that is also a splitter. This is useful for inserting it into the rear console connector where you have to kind of splice it into the current connector in order to add another one in.
