How to Find the OBD Port in Your Car
Share
In almost every car sold in India over the last decade, the OBD port sits under the dashboard on the driver's side — most often just above the pedals or tucked to the right of the steering column. The OBD-II standard actually requires the port to be reachable from the driver's seat without any tools, so it is never buried deep inside the car. Sit in the driver's seat, switch on your phone torch, duck your head under the steering wheel, and scan the plastic panel above the pedals. That single move locates the port in the vast majority of Indian cars in under a minute. Here is what the port looks like, where popular brands usually place it, and what to do if yours is playing hide-and-seek.
The 10-second checkStart under the steering wheel
Do this in daylight or with a torch, because the port usually faces downward — you see it edge-on rather than head-on, which is why people miss it. Check three zones in order. First, look directly beneath the steering column, on the underside of the dash. Second, scan the panel above the pedals, roughly where your knee sits while driving. Third, run your eyes along the right-hand edge of the dashboard near the driver's door, where the fuse-box cover usually is. In many cars the port hangs from a small bracket; in others it is recessed into the plastic or hidden behind a hinged flap that pops open with a fingernail.
Know what you're looking forA 16-pin trapezoid you can't mistake
The OBD port — technically the Data Link Connector — looks the same in every car because it is standardised. It is a female socket about four centimetres wide, shaped like a flattened trapezoid (a D lying on its side), with 16 pin slots arranged in two rows of eight. The plastic is usually black or white, and some carmakers add a rubber dust cap or a cover marked \"OBD\" or \"DLC\".
Quick ID checklist: 16 pin slots in two rows • trapezoid shape, wider at the top • about the width of two fingers • always accessible without removing any screws. If you need a screwdriver to reach it, you're looking at the wrong thing.
One detail worth knowing: pin 16 of the port carries power directly from the car's battery. That is why devices plugged into it — diagnostic scanners, plug-and-play GPS trackers — need no wiring and keep working even when the ignition is off.
Brand by brandWhere popular cars in India usually keep it
Exact placement varies by model year, but the patterns are consistent. In most Maruti Suzuki models — Swift, Baleno, WagonR, Dzire — the port sits under the dash just right of the steering column. Hyundai models like the i10, i20, Venue and Creta typically place it on the driver's side under-dash area, sometimes close to the bonnet-release lever. Tata cars such as the Nexon, Punch and Tiago usually keep it near the driver's-side fuse box, occasionally behind a small plastic flap. Mahindra SUVs — XUV lines, Scorpio, Thar — generally put it under the dash on the driver's side as well, and Honda and Toyota follow the same convention. If you want certainty for your exact variant, open the owner's manual index and look for \"OBD\" or \"Data Link Connector\" — every manual lists the location.
TroubleshootingStill can't find it?
A few cars are sneakier. Check behind the fuse-box cover itself, behind a removable coin tray, or above the driver's footrest. In a handful of older or imported models the port hides near the centre console. Two reassurances: if your petrol or diesel car was sold in India in 2013 or later, an OBD-II port is effectively guaranteed, and most cars from 2010 onward have one too. A CNG retrofit does not remove it. Electric vehicles are the one grey area — many EVs have the physical port, but what it reports varies by manufacturer.
Why it mattersWhat this little port can actually do
Mechanics use the OBD port to read fault codes — it is how a service centre decodes a check-engine light in minutes instead of guessing. A basic Bluetooth scanner costing a few hundred rupees lets you read those codes yourself on your phone. The same port is also why modern plug-and-play GPS trackers install in seconds: a device like the DontTouch Chowkidar for Car pushes straight into the OBD socket and is live immediately, drawing power from the port with no cutting, splicing or garage visit. Once you know where your port is, everything that uses it becomes a ten-second job.
FAQCommon questions
Practically all petrol and diesel cars sold from 2013 onward have an OBD-II port, as emission norms of that era required it. Most cars from 2010 onward have one too. Only much older vehicles may lack it.
Yes — the port is designed for continuous connection, and well-designed low-power devices draw a tiny current. If the car will sit unused for several weeks, remember that any always-on electronics adds a small battery drain.
Simply reading data or using a plug-in accessory does not void a warranty — the port is a standard service interface that dealerships themselves use. Modifications that alter engine behaviour, like ECU remaps, are a different matter.
