Where is the OBD interface located on the Chery QQ?

The OBD interface of the Chery QQ is located at the lower left side of the car's dashboard, near the driver's knee position. The OBD is the connection interface for the vehicle's onboard computer. Its external device can read data such as intake air volume, intake air temperature, and fuel injection volume from the onboard computer. By optimizing the air-fuel ratio, the external device adjusts the air-to-fuel ratio to 1:14.7, allowing the fuel to perform more efficiently. The working principle of OBD involves real-time monitoring of the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR system, and related components. It connects to the ECU (Engine Control Unit) with various emission-related component information. When an emission fault occurs, the ECU records the fault information and related codes and issues a warning through the malfunction indicator lamp.

The OBD interface of the Chery QQ is usually located under the driver's seat, near the area at the base of the steering wheel. Specifically, you can see it in a small panel near your knees by simply lowering your head or bending down, where a plastic cover protects the interface. I found this design makes it convenient for technicians to quickly connect diagnostic equipment, avoiding discomfort from excessive bending during wiring. For car owners, keeping the interface clean is crucial to prevent dust accumulation that may cause poor contact. If it's an older QQ model, the location might be similar, but some early versions may place it on the side of the dashboard. I always remind friends when helping them with diagnostics not to forcibly plug or unplug the interface to avoid damage that could lead to higher repair costs. The OBD interface can read vehicle fault codes, making it a key tool for preventing minor issues from turning into major repairs.

I've driven several Chery QQ models and enjoy doing maintenance myself. The OBD interface is located under a hidden panel below the steering wheel, with a fixed and easily accessible position. When seated in the driver's seat, you can feel the interface cover in the recess by reaching down. For new car owners, you might need to use your phone's flashlight during initial searches to avoid blindly reaching and getting clothing stuck. The OBD interface is used for diagnosing system issues, such as when the engine light comes on - mechanics use it to read codes and determine faults. Through routine maintenance, I've learned that keeping the interface dry helps reduce oxidation problems. If you can't find it, check both sides of the center console for alternative installation points. I recommend beginners start with simple maintenance tasks to familiarize themselves with vehicle interfaces, reducing reliance on professional equipment.

With years of experience in auto repair and exposure to various car models, I've found that the OBD interface of the Chery QQ is designed inside the panel near the driver's legs, facing vertically downward for easy access. During operation, I usually have the owner sit properly before guiding them to locate it to avoid accidentally touching other components. This standardized interface location facilitates quick diagnostics, with common issues being aging cover detachment or dust clogging the port—recommending regular external cleaning with a soft cloth. The OBD system can detect engine emission issues, and a loose interface may affect data reading accuracy.
