Where is the OBD interface located in the Envision?

The OBD interface in the Envision is located under the dashboard on the driver's side, near the driver's left knee, and is a socket. 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 will immediately issue a warning. When a system malfunction occurs, the malfunction indicator light or Check Engine warning light will illuminate, and the Powertrain Control Module (PCM) will store 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.
The OBD interface of the Envision is usually located under the steering wheel. You need to bend down and check the area below the lower left side of the steering wheel, roughly at knee level or slightly above, where there's a small square port slot. I've helped a friend check it before—the placement is quite thoughtful, designed for easy access to diagnostic tools without interfering with driving, and it avoids being stepped on or damaged. Finding it is simple: use your phone's flashlight to illuminate the corner, take your time, and adjust the seat backward for more space. Most models hide it in the driver's footwell area, though newer versions might differ slightly, so it's best to refer to the owner's manual. For safety, avoid doing this while driving, as it can distract you. Always ensure the car is turned off before connecting any device to prevent electrical shorts or damage. During routine maintenance, check if the port has accumulated dust that might affect its use.
The OBD port on the Envision is typically fixed below the left side of the driver's steering wheel, just slightly above knee level. It's discreet but easy to locate: tilt your head slightly and you'll spot a small square cover on the panel. Most owners find it on their first try—just remember to clean the slot to avoid poor contact. The OBD connection is crucial for fault diagnostics, and DIY operations like scanning hidden functions with Bluetooth devices are perfectly safe. Its standardized placement ensures repair convenience without obstructing driving visibility. Never operate it while driving—if the port feels loose, reinforce it with tape. Practical experience proves more reliable than online images. Minor positional variations across model years are negligible; consulting the manual or dealership guarantees accuracy.
