The diagnostic interface of BAIC Huansu is located under the glove box on the passenger side, which can be seen by simply moving the passenger seat. Below is the relevant introduction: Computer diagnosis: Computer diagnosis refers to the OBD system, specifically the On-Board Diagnostics system. Its common function is to continuously monitor the faults of components and systems. When a fault is detected, it alerts through the warning indicator on the dashboard. Introduction to BAIC Huansu S3: The BAIC Huansu S3 is a vehicle under BAIC Yinxiang Automobile Co., Ltd., independently developed over more than three years, positioned as a compact SUV in the market. As a compact SUV, it features seven seats, which has become its biggest selling point. In terms of power, it still uses a 1.5L displacement engine, with a maximum power of 83kW (113PS) and a maximum torque of 150Nm, paired with a 5-speed manual transmission.
I've been driving my own BAIC Huansu for three years, and the diagnostic port is right under the steering wheel, easily visible when you look down. It's behind that plastic panel above the driver's left knee—there's a black trapezoidal port with a small cover. Just pry it open to reveal the OBD socket. It's very convenient to connect a scanner myself, but I’d remind you not to use excessive force when plugging or unplugging, as the port pins are quite delicate. Always make sure the car is completely turned off before scanning, or the dashboard might throw error codes—last time, I carelessly plugged in while the engine was running, and the ABS light stayed on for half an hour. If you have floor mats, move them aside, as they can block the port. I recommend keeping a phone flashlight handy for better visibility.
Last time I went to the repair shop for maintenance, the technician showed me how to locate the diagnostic port for the BAIC Huansu. It's inside the plastic cover on the left side of the steering column—just crouch down and look above the accelerator pedal area to find it. Those standard 16-pin OBD ports are usually hidden in the space below the steering wheel. It's best to adjust the seat backward when connecting for more operating space. Mechanics often encounter foreign objects stuck in the port, so they recommend cleaning the pins with a fine brush every six months. During diagnosis, make sure the key isn't in the ACC position, as it may trigger the anti-theft system on some models. Using a Bluetooth scanner is more convenient, as the data cable won't get tangled around the pedals.
From the perspective of vehicle design principles, the OBD interface layout of BAIC Huansu complies with industry standards. It is typically installed within easy reach of the driver, specifically on the steering column cover beneath the steering wheel. This location is chosen for both quick access by maintenance personnel and to prevent exposed wiring from affecting aesthetics. The interface is internally equipped with a dust cover to protect the pins, but the spring clip tends to loosen after prolonged use. The onboard diagnostic system requires stable communication protocols, so it is advisable to avoid installing strong magnetic devices or modifying circuits near the port. It is recommended to observe the status indicator light each time a diagnostic tool is connected; continuous flashing indicates a communication fault. Regular maintenance of the interface with electronic contact cleaner can extend its service life.
