Tesla vehicle Diagnostic Cable Adapter – For the early Tesla Model S, Pre September 2015

The Tesla Model S is equipped with a propitiatory diagnostic data connectors. This connector gives users access to a lot of useful information about your Model S, 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

The propitiatory diagnostic connector on the Model S 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.

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. Available Here.

PLEASE NOTE. If your Model S has had an MCU swap, your Model S may have the later connector, and you should order the combo cable here to be sure you can connect to your car.

Model S Variations.

There are two versions of the connector depending on when your Model S was built. If your Model  S was built after September 2015, so will need the post sept-2105 cable.

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.
