Where is the Tesla OBD port located?

Tesla's OBD port is located behind the small storage compartment beneath the large infotainment screen. OBD stands for On-Board Diagnostics, which translates to "on-board automatic diagnostic system" in Chinese. This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it immediately issues a warning. Below is a detailed introduction to the OBD system: 1. Brief Introduction: OBD, short for On-Board Diagnostics, is a diagnostic system extended for automotive fault detection. 2. Working Principle: The OBD system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed standards. If they do, it immediately issues a warning. When a system fault occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. Simultaneously, the Powertrain Control Module (PCM) stores the fault information in memory. Through a specific procedure, the fault code can be read from the PCM. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. 3. Scope of Coverage: OBD monitors in real-time systems and components such as the engine, catalytic converter, particulate filter, oxygen sensors, emission control system, fuel system, EGR, etc. It then connects to the ECU through information related to various emission-related components.
I've always been fascinated by Tesla cars, so I did some research on where the OBD interface is located. On the Model 3 and Model Y, it's right under the steering wheel. If you crouch down, you can see a small plastic cover near the top of the brake pedal. Pry it open, and you'll reveal the diagnostic port. As an electric vehicle, Tesla's port can also connect to a mobile app or third-party scanning tools to read data, such as battery health or fault codes, which is very convenient. I remember when I first started tinkering, I almost couldn't find it because the design is quite hidden, but with a little exploration, you'll get it. Checking it before driving out can help detect minor issues in advance, preventing problems midway, especially during long trips. The location may vary slightly in different models, like the Model S being a bit more to the left, but it's generally in the driver's footwell area.
