Where is the OBD interface located on the new Excelle?

The OBD interface of the Excelle is located above the left side of the brake pedal. There is a bundle of wires; pull it out, and the OBD interface will be there. Below is some relevant information about the Excelle's OBD: 1. OBD: OBD is translated into Chinese as "On-Board Diagnostics." This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed the standard. If they do, it will immediately issue a warning. When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. At the same time, 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. 2. The development of OBD: In its later development, OBD gradually expanded its control scope. With the increase in various sensors and the level of electronicization in vehicles, OBD has incorporated various monitoring functions into its jurisdiction. Nowadays, when people refer to OBD, they generally use the term "OBD interface" because only the transmission interface of this system is visible on the vehicle, but it represents the collective body of the vehicle's control system.
The OBD port of the new Excelle can be found on the driver's side. Just crouch down and look below the steering wheel on the left, near the knee area above the pedal. There's usually a small black box socket that's easy to spot. I often use it to connect my phone's diagnostic app to scan for trouble codes, saving a trip to the repair shop. The port location is similar in most car models, and Buick's design is quite user-friendly, making it easy to plug in a diagnostic tool or install a GPS tracking device. Knowing this location allows you to handle minor issues like clearing fault lights yourself, but it's recommended to turn off the engine to prevent short circuits. If you can't find it, check under the driver's side dashboard or near the floor mat, and avoid pulling the wires forcefully. Keep the port clean to prevent dust from affecting the connection.
Having driven for over a decade, I'm quite familiar with the OBD port on the new Excelle. It's located in front of the driver's seat—just bend down and look near your left leg, above the brake pedal area. Usually, it's quite noticeable with a label. I remember modifying the car computer system myself when I was younger; knowing the fixed port position made plugging in devices much smoother. The location might vary slightly across different model years, but it's generally in this area. Once you're familiar with its position, you can use it to read the car's health status, like checking fuel consumption or emission data, which is quite practical. Be gentle when operating it—don't yank hard, as the small port can be easily damaged. If it's too dark to see clearly, use a flashlight to confirm the position and avoid plugging into the wrong hole.
