The computer connector of Huansu S3 is located under the glove box on the passenger side. Move the passenger seat to the rearmost position to see it. Below is some information about this vehicle: 1. Exterior: The new model remains largely consistent with the current version, featuring the Beiqi family's signature "X"-shaped front grille. The dimensions of the new model are 4380/1730/1720mm (length/width/height), with a wheelbase of 2685mm. It adopts a 7-seat layout, offering over 20 seating configurations, ample storage space, and a maximum luggage compartment expansion space of 1668L. 2. Interior: The design largely retains the style of the current model, with the color scheme updated to a warmer gray. The 1.5L Comfort variant adds a rearview camera, while the 1.5L Luxury variant includes an electric sunroof. 3. Powertrain: This vehicle continues to use a 1.5L engine, delivering a maximum power of 83kW (113PS) and a maximum torque of 150Nm, paired with a 5-speed manual transmission.

As an experienced driver who often maintains my own car, the diagnostic port of the Huansu S3 is located behind the plastic cover panel below the steering wheel, right where your knees are. You can see it by looking down – it's a palm-sized black trapezoidal connector with a standard 16-pin OBD interface. Some owners might miss it because it's positioned quite low; you'll need to bend down to spot it. Remember to turn off the engine power before connecting a diagnostic tool. I've seen cases where sparks flew from the battery during plugging/unplugging. Don't randomly insert devices into this port, especially those cheap fuel-saving gadgets bought online, as they might interfere with the ECU data. If you absolutely can't find it, run your hand along the wiring below the steering column – you'll definitely feel that hard plastic connector with a dust cover.

Last time I helped my neighbor troubleshoot their Huansu S3, I specifically took photos of the connector locations. Crouching in the driver's seat and looking under the dashboard, about 20 cm above the accelerator and brake pedals, you'll notice a trapezoidal slot (6 cm long and 2 cm wide) protruding from the edge of the black plastic cover. The dust cap is engraved with '16PIN'. This area typically houses the fuse box and ECU connector. Beginners should remember to disconnect the battery negative terminal before removing panels for access. Using a phone flashlight shining upward from below provides better visibility—just be careful not to let floor mats interfere with the cover's clips. Huansu models consistently position connectors in this zone, though dust cap shades may vary slightly across model years.

Auto repair shops often encounter car owners who can't locate the diagnostic port. The OBD port of the Huansu S3 is hidden at the bottom of the steering column plastic cover. When bending down, pay attention to the triangular area between the dashboard and the door hinge. The port is an ISO-standard DLC3 trapezoidal socket, tilted downward at a 45-degree angle for easy plugging and unplugging. When connecting the diagnostic tool, power on the vehicle but do not start the engine. Last year, a vehicle converted to natural gas had additional wiring harness installed in this position, causing poor contact. If you can't find it, try adjusting the seat to the rearmost position, lie down on the driver's cabin floor, and look up—it's much less strenuous than searching while standing.

Newbie mechanics should remember: BAIC Huansu vehicles all have their OBD ports located at the lower left corner of the cabin. Specifically for the S3 model, sit in the driver's seat, press your right toes against the base of the brake pedal, and reach up 45 degrees to the left to feel the ribbed dust cover. This design facilitates dealership maintenance but makes the port prone to water splash during car washes. It's advised to check for oxidation on the copper pins during each service. Last month, we handled a case where spilled milk tea caused communication failure. In older models, the port might be obscured by additional GPS wiring harnesses—just push aside the harness to reveal the black socket secured by metal clips.
