Tesla vehicle Diagnostic Cable Adapter – For Tesla Model S, Model X And Model 3 Diagnostic data port.

The Tesla Model S, Tesla Model 3 and Tesla Model X are equipped with a propitiatory diagnostic data connectors. This connector gives users access to a lot of useful information about your Model S, 3 & X, such as battery capacity, battery voltage, drive-train output, HVAC data etc..

There are a few 3rd party apps that are available, that with the use of an OBD-II module, and a diagnostic cable, will read this data and display it in human readable form.

These cables can also be purchased as part of a Tesla Diagnostic Bundles HERE

Location of Diagnostic connector

Model S and Model X

The propitiatory diagnostic connector on the Model S and X can be found between the front screen and the cubby. To get access the connector you need to pull the front of the cubby in a downwards direction (not towards you). It is held in place with two metal clips near the front of the cubby. The cubby can be easily clipped back in-place.

Model 3

The Model 3 Port is located at the rear of the centre console and accessible from the rear footwell.

Different versions of connector and diagnostic cable.

  • Pre Sept 2015 – For Tesla Model S manufactured before September 2015.
  • Post Sept 2015 – For ALL Tesla Model X and Tesla Model S manufactured after September 2015.

Model S/X Variations.

There are two versions of the connector depending on when your Model S/X was built. The Model X was built after September 2015, so will need the post sept-2105 cable, if your Model S was built before September 2015 you need the pre sept-2015 cable.

Model 3 Variations.

There are two versions of the connector depending on when your Model 3 was built. We presently only supply cables for post January 2019 BUILD DATE Models.

Please note that your vehicles BUILD DATE is NOT the same as the date of first registration.

The Tesla Model 3 MUST be shut down before inserting the cable in to the loom.  The shut down takes 15 minutes to complete and is performed from the screen within the vehicle.  Failure to shut down the car before inserting the cable into the loom may damage your vehicle and or cause faults.

Application software And Hardware.

You will need to purchase an OBD-II adapter as well as the application software to decode and display the data off the diagnostic connector.

Application software currently available is ScanMyTesla (Android) and TMSpy For Andriod Or TMSpy For IOS. Either app will work with the ELM327 compatible OBD-II bluetooth adapter, with the above cable. Care must be taken when selecting the OBD-II adapter, as not all cheap adapters support the CAN bus protocol (even if they say they do). We would recommend an ELM327 V2.2, but any high quality adapter that supports the ST command set is recommended. Please refer to application software for further help with ODB-II adapter selection.

Please note.  Connecting equipment to your Tesla is done entirely at your own risk.  EV Accessories Limited will not be held responsible for any damage caused to your vehicle through incorrect use of this product. The user is responsible for checking for any damage to the cable prior to use. both upon receipt and for each and every use.
