Tesla Model 3 and Model Y don’t have a standard OBD2 port like most gasoline cars. Instead, they use a diagnostic port located in the rear passenger footwell. This port requires a special adapter to connect with standard OBD2 tools and software. Let’s explore how to access data from your Tesla and what kind of information you can get.
Accessing Tesla Data with an OBD2 Adapter
Accessing your Tesla’s data requires an OBD2 adapter compatible with Tesla’s diagnostic port and an ELM327 or STN1110 compatible OBD2 tool or device. Popular choices include the OBDLink LX or MX Bluetooth devices. This adapter bridges the connection between the Tesla’s unique diagnostic port and your OBD2 scanner, allowing you to tap into a wealth of vehicle information.
Unlocking Insights: Popular Tesla Diagnostic Apps
While Tesla’s security protocols prevent modifications to critical systems, connecting to the diagnostic port allows access to live vehicle data using dedicated apps. Two popular options are Scan My Tesla and TM-Spy, available for both Android and iOS devices.
