The OBD interface in the Sylphy is located behind the plastic cover under the steering wheel. You need to use a flat-head screwdriver to pry open the cover to see the OBD interface. The Sylphy is a new strategic model launched globally by Nissan, featuring innovative design and advanced technology. The dimensions of the Nissan Sylphy are 4665mm in length, 1700mm in width, and 1510mm in height, with a wheelbase of 2700mm. The Sylphy is equipped with a new 2.0 engine, coded MR20DE, which is made of all-aluminum. Through the adoption of new technologies, the MR20DE engine achieves high output power, high torque, lightweight, low fuel consumption, low noise, and compliance with Euro IV emission regulations.

I remember when I helped a friend repair their Sylphy, I studied the location of the OBD port—it's just below the steering wheel on the left side. Crouch down and look towards the bottom of the dashboard, and you'll spot it. There's a black trapezoidal port there, about the size of a USB flash drive. Once, when the car's fault light came on, I plugged in a diagnostic tool and checked for a long time, only to find out it was just a false alarm because the fuel cap wasn't tightened properly. The port on older Sylphy models is a bit more hidden, possibly tucked behind a plastic trim panel, requiring you to pry open a small cover. The newer models make it much more obvious. When working on it, remember to turn the key to the power-on position before operating, otherwise some data won't be readable.

A friend bought a used Sylphy and asked where the OBD port is. I directly told her to sit in the driver's seat and look for a black plastic box to the upper left of her left foot. It's less than 30 cm between the accelerator pedal and the door, right against the edge of the dashboard. You can feel the slightly raised trapezoidal cover with your fingertips. I recommend beginners familiarize themselves with the port location before a diagnostic cable. Last time, someone mistook the port for an anti-theft device socket and wasted half a day. Japanese car designs are quite standardized, unlike some American cars that hide it in the glove box, which is a hassle.
