Where is the Chery QQ computer diagnostic connector located?
4 Answers
The OBD computer diagnostic connector for the Chery QQ is located below the right storage compartment. Here are the detailed explanations: 1. The vehicle diagnostic interface, also known as the OBD interface, is an electrical socket for the onboard automatic diagnostic system. When connecting, it should be inserted while the power is off. The vehicle diagnostic interface has a total of 16 pins, each representing a different function. 2. Generally, 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 only for power supply or detecting battery voltage and current. 3. When checking the battery, there is no need to open the engine cover; simply insert the OBD device, which is very convenient. 4. The remaining pins can have their functions set by the manufacturer.
I recently helped a friend fix a Chery QQ and got quite familiar with its diagnostic port. That port is located just below the steering wheel, on the driver's side. You'll need to crouch down and look under the dashboard, usually near the area around the accelerator pedal. It's a small trapezoidal connector, possibly in a black-gray color scheme, and can be spotted with some careful searching. I remember it took me a while to find it last time because it's tucked away quite deep, designed to be dust-proof and protected from damage. I recommend turning off the engine before checking to ensure safety and avoid harming yourself or the electronic systems. Also, the location is pretty much the same for both older and newer models of the Chery QQ, so it shouldn't be too far off. If you really can't find it, use a flashlight or flip to the back section of the owner's manual—there's a diagram that pinpoints the exact spot, which can save a lot of hassle. Connecting an OBD-II device to the diagnostic port to read fault codes is super useful, and it’s also handy for routine maintenance checks, so don’t overlook it.
As an auto mechanic, I'll tell you that locating the diagnostic port on a Chery QQ is quite straightforward: it's on the driver's side, in the lower left corner area below the steering column. Specifically, if you look down, you'll spot a small black rectangular-shaped port at the bottom of the instrument panel. It's usually fixed in that position and doesn't move around. Why is it designed there? Mainly for easy scanner access and crash protection. Remember to turn off the engine before connecting, and avoid touching metal parts to prevent short circuits. Some owners complain about difficulty finding the port - it might be covered by floor mats or clutter, so clear the area first. Also, the Chery QQ's port is similar to most domestic brands - durable but not moisture-resistant, so always replace the protective cap after use to prevent rust issues. I'm sharing this to help make your diagnostics smoother, because safety always comes first!
When I used to drive a Chery QQ, I tinkered with the diagnostic connector myself and found its location quite decent. It's positioned under the steering wheel, slightly to the left, near the driver's footwell area. If you crouch down and feel around the bottom of the dashboard, you'll find a small port. The first time I looked for it, I was a bit confused, but got used to it later. Remember to have good lighting—it's clearer under bright light. It's safer to turn off the engine before using it each time, unlike me rushing and making mistakes. The placement of this connector is quite reasonable, avoiding frequent wear from the driver's usual activity zones. If it's hard to spot, try adjusting the seat to give yourself more space to maneuver.
