The OBD interface of the Chevrolet Sail is located at the lower part of the steering column cover on the driver's side, specifically below the steering wheel and directly above the driver's accelerator pedal. OBD stands for On-Board Diagnostics, a system that continuously monitors the engine's operating conditions to detect whether the vehicle's emissions exceed standards. If emissions exceed the limit, the system will immediately issue a warning. The Chevrolet Sail is a joint-venture brand model under SAIC-GM, with body dimensions of 3947mm in length, 1690mm in width, and 1503mm in height, and a wheelbase of 2465mm. The front grille of the Chevrolet Sail adopts the Chevrolet family design, featuring a double-layer design centered around the Chevrolet logo. The headlight shape is similar to that of the new Lova, giving it a relatively stylish appearance.

I recently helped a friend locate the OBD port on a Sail. That thing usually hides in the lower left corner behind the steering wheel—you’ll need to crouch and look toward the bottom of the dashboard, right above the accelerator pedal behind a plastic trim panel. On older Sail models, you might have to duck your head under the steering wheel to spot it. The port is a standard 16-pin blue rectangular socket. Some owners mistake its absence for a malfunction, but it’s just cleverly tucked away. My advice: feel for it manually. About 15 cm above the plastic cover, there’s a recess where you can detect the edge of the port. If floor mats are installed, check for obstructions—it’s best to clear any clutter under the driver’s seat. This location is practically standardized for all post-China IV emission compliance vehicles.

When working on cars, I've come across quite a few Sail models, and the OBD port is located in the area facing the driver's knees. To be specific, after sitting in the driver's seat, look down at the lower left side of the steering wheel, behind the black plastic trim panel where your knees rest. The location has remained largely unchanged between old and new models, though it's tucked deeper in older Sail models. You can reach your hand along the lower edge of the dashboard to feel a trapezoidal port with a dust cover. When plugging in a diagnostic tool, remember to open the small cover first—I've seen people break it by applying too much force. This placement is mainly designed for easy access to diagnostic equipment while preventing accidental contact with feet. If you can't find it, try using your phone's flashlight for better visibility than the dome light.

The OBD interface of the Sail is located in the plastic cover panel below the left side of the steering column, in front of the driver's legs. The interface adopts a standard DLC-16 pin structure, approximately three fingers wide. It's indeed not easy to locate - it took me five minutes to find it the first time. Here's a tip: adjust the seat to its rearmost position, squat outside the car door and bend over to look - the interface is embedded in a groove of the trim panel. Newer models have a position diagram sticker on the side of the glove compartment base, which I recommend checking. This interface mainly reads engine data; connecting a Bluetooth diagnostic module can retrieve trouble codes. Be careful not to spill drinks on it. Its position is basically the same as that of the Cruze.
