Where is the diagnostic connector for the C4L?
3 Answers
The diagnostic connector for the C4L is located in front of the gear shift, near the USB port and cigarette lighter. By touching the area, you can feel a small hole. Use your finger to pull it open, and you will find the OBD interface inside. OBD stands for On-Board Diagnostics, and this interface can be connected to a diagnostic computer to read the vehicle's fault codes, making it an important component in the car. The C4L has dimensions of 4675mm in length, 1780mm in width, and 1500mm in height, with a wheelbase of 2710mm. It is a 4-door, 5-seat sedan equipped with a 5-speed manual transmission.
I've been driving the C4L for ten years, and the diagnostic port is located under the dashboard, in the corner to the left of the steering wheel. I remember it took some effort to find it the first time, but later I got familiar with its location—it's at knee height, a square-shaped port where you can easily plug in the diagnostic tool. It's quite useful, like reading fault codes or adjusting vehicle data. When operating, make sure the engine is off and the key is turned to cut the power to avoid short circuits or device damage. The location is well-designed, so it's not easily bumped into while driving. I also recommend owners regularly check the port for dust buildup—cleaning it with a soft brush can maintain a stable connection. Additionally, if there's a need for modifications, like installing a real-time monitoring device, the port is right there ready for use.
As a C4L owner, locating the diagnostic port was quite straightforward: it sits on the dashboard just below and in front of the driver, slightly to the left of the steering wheel. When I first got my car, I had to explore a bit—the port is concealed in the knee-height area, featuring a standard small square socket. Its function is to connect diagnostic tools for scanning vehicle issues, such as when the engine light comes on. While driving, it goes unnoticed, but when needed, it's conveniently accessible—just bend down to reach it. The placement is highly standardized, as most vehicles follow this arrangement to avoid driver distraction. I also learned that keeping the port clean is crucial, as dirt can interfere with signal transmission. You can easily purchase a small cleaning tool from e-commerce platforms—affordable and handy.
