The computer interface of BAIC Weiwang M20 is located under the co-driver's blower. The computer diagnostic system refers to the OBD system, specifically the On-Board Diagnostics system, which continuously monitors the faults of components and systems. When a fault is detected, it alerts through the warning indicator on the dashboard. The BAIC Weiwang M20 adopts a new family-style design element, featuring a double U-shaped front air intake grille that complements the newly added silver lower guard at the bottom of the front bumper, giving it a strong recognition. In terms of interior, the BAIC Weiwang M20 is largely similar to the existing models, with the difference being the extensive use of soft materials, which enhances the sense of quality. Additionally, the vehicle has a 7-seat layout in a 2+2+3 format. For power, it is equipped with a 1.5L engine, delivering a maximum power of 85 kW and a maximum torque of 150 Nm, paired with a 5-speed manual transmission.

I usually drive a BAIC Weiwang M20. Last time at the repair shop, the owner mentioned that the computer interface is usually installed near the left side below the steering wheel at leg level. If you crouch down and look towards the foot brake, you'll spot a small black box with a plastic cover. Sometimes it's also found at the rear corner of the side storage compartment next to the driver's seat. For older models, the interface is mostly tightly attached next to the steering column, requiring you to lift the carpet or plastic trim to find it. Plugging a small device into this interface can read the vehicle's fault codes, instantly revealing issues like the engine light coming on, saving you the hassle of long queues at 4S shops. I think it's good to occasionally check if the interface is covered by dust and keep it clean to avoid poor contact and false fault reports during diagnosis, since daily driving relies heavily on electronic systems for safety.

As someone who enjoys tinkering with car repairs, I've played around with quite a few diagnostic devices. The OBD port of the BAIC Weiwang M20 is usually located on the instrument panel bracket below the steering wheel on the driver's side. Just feel around with your hand to locate the 16-pin connector. Don't just focus on the port location—once connected to a scanner, it can detect the status of all electronic modules including the engine and ABS. If the warning light is on or acceleration is sluggish, simply plug it in to read the specific fault codes. I also recommend checking the wiring harness for signs of aging or looseness. Sometimes, vibrations on bumpy roads can cause poor contact due to port wobbling, leading to misjudgments by the car's computer. Addressing this early can prevent the risk of breaking down midway. During regular use, make sure rainwater doesn't seep into the area—keeping it dry prevents corrosion and ensures smooth data reading.

Having driven for many years and being attentive to driving safety, I always check the computer interface for diagnosis at the first sign of any abnormal noise or warning light. The interface for the BAIC Weiwang M20 is typically located in the area in front of the legs on the left side of the steering wheel. Just flip open the cover to see the standard OBD port. Connecting a diagnostic tool takes only a few seconds, and reading the data promptly can prevent minor issues from escalating into major accidents. For instance, detecting unstable battery voltage or sensor malfunctions through the interface allows for quick repairs, ensuring safety and peace of mind while driving on the road.
