Where is the diagnostic connector for Chery QQ?
2 Answers
The diagnostic connector for Chery QQ is located under the right storage compartment. Below are the detailed specifications of the automotive diagnostic connector: 1. Function: The automotive diagnostic interface, also known as the OBD interface, is an electrical socket for the On-Board Diagnostics system. It should be connected when the power is off. 2. Pins: The automotive diagnostic interface has 16 pins, each serving a different purpose. Pin 2 is the bus positive, Pin 4 is chassis ground, Pin 5 is signal ground, Pin 7 is the K-line, Pin 10 is the bus negative, Pin 15 is the L-line, and Pin 16 is solely for power supply or battery voltage and current detection. 3. Battery check: There's no need to open the hood to check the battery; simply plug in the OBD device. 4. Other pins: The remaining pins can be assigned functions by the manufacturer as needed.
I remembered looking for the diagnostic port of the Chery QQ. It's located under the steering wheel on the driver's side, near the floor area. Squat down and feel around with your hand—you'll usually find a small square opening covered by a plastic cap to the left of the accelerator pedal or footrest. Open the cap, and inside is the OBD-II port, which is used to connect a diagnostic tool for reading trouble codes. For example, when the engine light comes on or acceleration feels sluggish, plugging in a device can help quickly identify the root cause. I recommend using an interior light or phone flashlight in dimly lit areas to avoid bumping your head. Remember, don't pull too hard on the connector, as damaging the port could affect vehicle diagnostics. Also, pay attention to this spot during routine maintenance to keep it clean and prevent dust buildup. The exact position may vary slightly depending on the model year, but most Chery QQs have it here—very standard.
