ODB port

[YauKwan]

Did a search and didnt find anything about this. Does the Model 3 have the ODB port. If so, where is it?

Thanks

I don't believe it has one. I believe it has some proprietary port though for diagnostics. I should be on the lower dash somewhere, down by the pedals.

Apparently the OBD port is only required for cars with engines or emissions

I checked my car and it has something which looks like a proprietary 5-pin port in the approximate location where the OBDII port is usually located .

I thought Tesla’s (at least S and X) had OBD ports. They just don’t function and provide same data as ICE car OBD ports. But I thought it did have one that would provide some data. Or at least power. And then not sure what the 3 has or not. Or does or not.

Yes, the S and X do have one. The 3 does not. The post above yours shows the port I was talking about.

I understand early Model S didn't have them, but were added later. I'm surprised not to see one on M3. I believe it's US law that requires the port on every car no matter what. Maybe they finally relaxed the law for EV.

The EPA documents basically stated it’s not required.

Interesting. Anyone have the relevant excerpt from that document to share here? As far as I knew, it was required for all cars. Interesting if EVs are exempted.

Interesting information here:

Oh, the answer to the question about exemption for OBD is on the first page. Upon further searching, this document was referenced in an electrek.co article back in Aug. 2017:

New Tesla Model 3 details revealed by EPA: ~80 kWh battery pack, 258 hp, and more

I heard there might be a CAN port on the 3? Any insight into this?

Check rtanov's post above.

 

[stetsoninc]

Is that photo you are referencing in rtanov's post a CAN interface?

Fleetcarma have engineered a wiring harness adapter that adds a standard OBD II Port to the Model 3. They did this to support their fleet tracking devices.

The harness adapter is installed behind an access panel at the rear of the center console near the floor between the front seats. Tesla have a wiring harness connector back there which the Fleetcarma harness is installed between the two connectors thereby adding an OBDII port.

I wonder what data that port provides ? On a Leaf the OBD provides good info.

I’ve also wondered how i can get to the data Tesla collects on my car.

Has anyone got any further with the pinouts on this connector and adapting it to an OBD?

Sadly this doesn't appear to work on post Jan 19 cars. Not sure why though. Jack posts to the M3OC (now TOO) forum.

I was able to add to cart, does it show up as sold out for you?

I didn't try to purchase the 2019 version, since my Model 3 is actually a 2018.
