Where is the diagnostic interface located?

The location of the OBD interface varies among different vehicle models. Here are the possible locations of the OBD interface: 1. Area A (the left area below the steering wheel): Most models of brands such as General Motors, Volkswagen, BMW, Ford, Toyota, Hyundai, Citroën, etc. 2. Area B (the right area below the steering wheel): A few models such as Volkswagen Touran and imported Lexus. 3. Area C (the area in front of the gear lever): A few models such as Dongfeng Citroën. 4. Area D (the area on the side of the driver's left guard plate): A few models such as Dongfeng Citroën.
When it comes to the location of the diagnostic port, as someone who's been driving for years, I've got plenty to share. Most modern cars, like Japanese and American models, position it under the steering wheel. Look down near the accelerator or brake pedal, and you'll often spot a blue plastic connector tucked along the dashboard edge—the 16-pin type. Sometimes it's in tricky spots, like by the driver's left knee or the passenger-side footwell, depending on the car's design. In my experience, Toyota sedans usually have it clearly visible under the wheel, but SUVs like Hondas might hide it lower near the floor mat. When searching, bend slightly and feel around carefully—avoid tugging wires for safety. The variation exists because OBD-II standards allow minor placement adjustments, which helps mechanics but can trip up beginners. Pro tip: Your owner's manual usually has diagrams. Safety first—don't jam tools randomly. If stuck, just ask a pro shop to save time.
As a new car owner, I remember the diagnostic port is typically located below the driver's side. Just look down near the steering column to find it, designed conveniently close to the accelerator or brake pedal for easy access while seated. Locations may vary slightly between models—my Ford sedan has a blue port exposed under the left side of the steering wheel, while my friend’s Honda places it beneath the glove compartment. It’s safer to locate it before starting the vehicle; checking the manual or searching online for your specific model speeds up the process. This port is meant for reading trouble codes during repairs, but avoid forceful disassembly—consult professionals to prevent mishandling. Keep the port dust-free to maintain diagnostic efficiency, a basic car care tip that enhances maintenance convenience.
