While the standard OBDII (On-Board Diagnostics II) port has been a staple in most modern vehicles for accessing diagnostic information, Tesla vehicles, known for their innovative technology, take a slightly different approach. If you’re wondering Does Tesla Have Obdii Link, the answer isn’t a straightforward yes.
Tesla Model 3 OBD2 Adapter Location
Instead of the conventional OBDII port readily accessible under the dashboard, Tesla Model 3 and Model Y vehicles utilize a console connector located in the back seat area. This means that to access the diagnostic data from your Tesla, you’ll need a Tesla OBDII adapter cable to bridge the connection between your vehicle and a standard OBDII tool.
This unique setup doesn’t mean Tesla vehicles are inaccessible for diagnostics. It simply requires a different approach. By using a compatible OBDII adapter, Tesla owners and technicians can still tap into the wealth of data their vehicles generate. These adapters essentially convert Tesla’s proprietary connector to the universally recognized OBDII format, allowing for the use of standard OBDII scanners and devices.
To effectively diagnose and monitor your Tesla Model 3 or Model Y, you will need two key components: a diagnostic port cable adapter specifically designed for Tesla vehicles and an OBDII tool or device that is compatible with ELM327 or STN1110 chipsets. Popular choices for OBDII tools among Tesla owners include the OBDLink LX or MX Bluetooth devices, known for their reliability and seamless connectivity.
Scan My Tesla App Interface displaying live vehicle data
Once connected, accessing Tesla’s diagnostic system primarily allows users to view live data through specialized apps and software. Due to Tesla’s robust security measures, deeper system modifications or reprogramming are generally restricted. However, the available live data is incredibly valuable for monitoring vehicle health and performance.
Two prominent apps in the Tesla community for accessing this live data are the “Scan My Tesla” app (available for both Android and iOS) and the “TM-Spy” app (Android and iOS).
The Scan My Tesla app provides a comprehensive overview of live vehicle statistics, including:
- Battery health metrics: power, voltage, current, and temperatures.
- Drive Unit performance data: electric power, torque, horsepower, RPM, and temperatures.
- Battery lifespan statistics, capacity estimations, and mileage.
- 12V system monitoring: current, voltage, and temperature.
- Trip recording and statistics, including charging information.
- HVAC system controls and readings.
On the other hand, the TM-Spy app focuses on detailed battery pack analysis, displaying information such as:
- Individual cell voltages for a granular view of battery health.
- Maximum, minimum, and delta cell voltages to assess battery balance.
- Histogram representation of battery pack balance.
- Temperature readings from 16 pairs of battery pack sensors.
- Total battery voltage and current during driving and charging cycles.
- Pack capacity and remaining energy in kWh.
- Mileage driven on the current battery pack.

The development of these valuable diagnostic tools and the understanding of Tesla’s data interface are largely attributed to the dedicated Tesla Model 3 community. Their efforts in identifying and compiling Tesla Model 3 CAN bus IDs and data have paved the way for accessible Tesla vehicle diagnostics. You can explore their collaborative findings in this document. Further appreciation can be given to the community at Tesla Owners Online.
In conclusion, while Tesla vehicles don’t feature a standard OBDII port in the traditional location, they are equipped with a diagnostic interface that, when used with the correct adapter and tools, provides access to a wealth of vehicle data. This allows owners and technicians to monitor vehicle health and performance effectively, ensuring optimal operation and maintenance. For those seeking to access this diagnostic capability, the OHP OBD2 Adapter for Tesla Model 3 & Y 2019-2020 Build is a recommended solution.
