Where is the OBD port located on the GAC Trumpchi GS4?

GAC Trumpchi GS4's OBD port is located near the left leg under the dashboard of the driver's seat, below the left side of the steering wheel, by the cover panel edge. OBD System: OBD stands for On-Board Diagnostic, which translates to "vehicle diagnostic system" in Chinese. The OBD system continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system. If it detects any situation that might cause excessive emissions, it will immediately issue a warning. When a system malfunction occurs, the vehicle's dashboard warning light will illuminate, and the OBD system will store the fault information in memory. Using standard diagnostic tools and interfaces, relevant information can be read in the form of fault codes. Based on these fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault. Connecting OBD to USB: First, run the ECANTools software installation program and follow the prompts to complete the installation. Then locate the vehicle's OBD port and connect the OBD port of the Guangcheng USBCAN-OBD device to the vehicle's OBD interface. Connect the other end's USB interface to the computer. This way, the OBD is connected to the USB.
Last time I helped my friend repair his GAC Trumpchi GS4, I specifically looked for the OBD port, and the design of this location is quite reasonable. It's right under the steering column on the left side beneath the driver's seat. If you bend down and feel around between the steering column and the brake pedal, you'll find a square plastic connector with a protective cover. It's actually easy to locate—just make sure the vehicle is turned off to avoid accidental electric shock, then lean down and use your phone's flashlight to see it clearly. This port is crucial for connecting diagnostic tools, especially when checking engine faults. Many people think it's in the passenger side or dashboard, but actually, 90% of cars are laid out this way. Remember to clean the dust regularly to prevent buildup that might affect the connection. The position isn't fixed and may vary by model, but for the GS4, it's definitely here. Next time you're troubleshooting, just try this spot directly.
