OBD2 Adapter Cable Tesla Model 3 2019 – Tesla OBD → 16-pin OBD2 (passive cable for external diagnostic tools)
Short Version
This OBD cable for Tesla Model 3 (2019) is a practical adapter cable that allows connecting external diagnostic tools with standard 16-pin OBD2 to Tesla's own diagnostic port. The product is described as an “OBD to OBD2 cable” and is used to replace/adapt the car's OBD interface when you want to connect an OBD2 scanner, logger, or other test equipment for troubleshooting and diagnostics.
Important: the cable is explicitly without functions. This means it does not contain electronics and does not “translate” protocols or unlock extra features – it is a passive connecting cable that simply provides the correct connector format for your equipment. Which data and functions you can read therefore depends entirely on your OBD2 device, the app, and what your specific car can expose via the diagnostic connection.
Perfect for workshops and enthusiasts who already have OBD2 equipment and want a simple cable to connect it for diagnostics on a Tesla Model 3, model year 2019.

The cable only provides a connection. What data you can retrieve depends on your scanner/app and the car's support.
3) Does it fit all Model 3s?
It is specified for Tesla Model 3 (2019). Check the model year and connector before purchasing.
4) Does the cable contain electronics?
No, it is described as “without Functions” and is therefore a passive adapter cable.
5) Where is the connector located in the car?
Location may vary. If you are unsure: follow the workshop manual or check the documentation for your specific car before dismantling panels.
Notes & Safety
- Turn off the car before connecting/disconnecting equipment and work carefully around panels and connectors.
- This is a passive adapter – it does not replace an OBD2 scanner.
- Check compatibility with your car (Model 3 2019) and that the connection matches before ordering.
