Where Is My OBD-II Port? Exact Location for Every Car Brand

What the OBD-II Port Looks Like

The OBD-II port is a 16-pin trapezoidal connector, wider at the top than the bottom. It is roughly the size of a wide USB port but taller and shaped like a trapezoid or a letter D turned on its side. The port is black or dark gray on most vehicles. All 1996 and newer gasoline vehicles in the US are required to have this port, and it must be located within reach of the driver's seat. It is almost always under the dashboard on the driver's side, but the exact position varies by manufacturer. Some ports are exposed and easy to see, while others are hidden behind plastic covers or panels.

What the connector standard actually requires

The port's position is not left to each manufacturer. SAE J1962 defines where it has to be and how reachable it has to be, and three of its rules explain the cases people find confusing.

• Commonly claimedThe port has to be within about two feet of the steering column.

  VerifiedThe requirement is a zone, and it is measured from the centre of the car rather than from the column. J1962:1995 §3.1 requires the connector be "located in the passenger compartment in the area bounded by the driver's end of the instrument panel to 300 mm beyond the vehicle centerline, attached to the instrument panel, and accessible from the driver's seat." That zone covers most of the dashboard width. Sitting "between the steering column and the vehicle centerline" is named in the same section only as the PREFERRED location — so a port over near the centre console is unusual, not non-compliant.

• Commonly claimedIf the port is hidden behind a panel or a cover, the manufacturer has broken the rules.

  VerifiedA cover is allowed; needing a tool is not. §3.2 says only that "access to the vehicle connector shall not require a tool for the removal of an instrument panel cover, connector cover, or any barriers." A trim panel that pops off by hand — the arrangement BMW, Volkswagen and Audi commonly use — meets the standard. If you genuinely need a screwdriver to reach it, that is the line being crossed.

• Commonly claimedIt should be somewhere you can spot from the driver's seat.

  VerifiedThe standard asks for close to the opposite. §3.3 states the connector "should be out of the occupant's (front and rear seat) normal line of sight but easily visible to a crouched technician." Being hard to see while seated is the intended design. Get your head down near the pedals and look up at the underside of the dash — that is the posture the requirement was written around.

Toyota and Lexus

On most Toyota and Lexus vehicles, the OBD-II port is located under the dashboard on the driver's side, just to the left of the steering column. On the Camry, Corolla, and RAV4, look directly below and slightly left of the steering wheel -- the port faces downward and is usually exposed without any cover. On the Tacoma and 4Runner, the port is in the same general area but may be recessed slightly further under the dash. Lexus models typically place the port in the same location with a small hinged plastic cover that you flip open. If you cannot find it visually, reach under the dash with your hand and feel along the bottom surface to the left of the steering column.

Honda and Acura

Honda moved the port around more than most brands. On the Civic (2006 and newer) it sits low on the driver's side -- under the dash near the pedals, often behind a small plastic cover; on the 2001-2005 Civic it is just above the pedals. On the Accord and CR-V, look under the dash on the driver's side, to the LEFT of the steering column. Only the oldest models (1996-2000 Civic) used the center-console location, behind a small panel near the front passenger's left knee. Acura models generally follow the same pattern. The Honda Fit and HR-V place the port directly below the steering column, which is more conventional. If you are having trouble, check both sides of the steering column and along the lower edge of the center console.

Ford and Lincoln

Ford consistently places the OBD-II port under the dashboard on the driver's side, directly below the steering column. On the F-150, Explorer, Escape, and Fusion, the port is easy to find -- look straight under the steering wheel and it is usually exposed, facing downward. On some models, the port is angled slightly to the left. The Ford Mustang places the port in the same area but it may be slightly further to the left near the kick panel. Lincoln models mirror Ford's placement. The port is almost never covered on Ford vehicles, making it one of the easiest brands to locate.

Chevrolet, GMC, and Buick

GM vehicles place the OBD-II port under the driver's side dashboard, typically just to the left of the steering column and below the fuse box cover. On the Silverado, Equinox, Malibu, and Cruze, the port is exposed and faces downward. On some Chevy trucks, the port is slightly recessed and you may need to look up from the footwell to spot it. GMC trucks and SUVs follow the same placement as their Chevrolet counterparts. Buick and Cadillac models also use the same driver's side location but occasionally place a small plastic cover over the port that you need to pull off or flip open.

BMW and Mini

BMW typically hides the OBD-II port more than other manufacturers. On most BMW 3 Series, 5 Series, and X-series models, the port is under the dashboard on the driver's side, but it is often behind a hinged or removable plastic panel near the driver's left knee area. Look for a small rectangular panel or cover along the lower left side of the dashboard -- pry it open or pull it downward to reveal the port. On the BMW E90 3 Series, the port is behind a small door in the lower kick panel to the left of the steering column. Mini Cooper places the port in the center console area or under the driver's dash depending on the model year. Always check for hidden covers on BMWs.

Nissan and Infiniti

Nissan places the OBD-II port under the dashboard on the driver's side, to the LEFT of the steering column on most models. On the Altima, Sentra, and Rogue, look at the left-hand side of the lower dash, above the footrest area. On the Nissan Frontier and Pathfinder, the port is in a similar position but may be angled toward the center console. Some Nissan models have a small cover or flap over the port. Infiniti vehicles follow the same placement pattern. On the 370Z and GT-R, the port location shifts slightly toward the center of the dash.

Hyundai and Kia

Hyundai and Kia make the OBD-II port easy to find on most models. On the Elantra, Sonata, Tucson, and Santa Fe, the port is under the dashboard on the driver's side, directly below the steering column and usually fully exposed. It faces downward and is visible if you lean down and look up under the steering wheel. Kia vehicles like the Forte, Optima (K5), and Sportage use the same straightforward placement. Some newer Hyundai and Kia models have a small plastic lip or cover, but the port is always in the same general area -- directly below the steering column, facing the floor.

Volkswagen and Audi

Volkswagen places the OBD-II port under the dashboard on the driver's side, but it is often hidden behind a removable or hinged cover. On the Jetta, Golf, Passat, and Tiguan, look for a small rectangular cover or panel on the lower left side of the dashboard, near the driver's left shin. Pull or pry the cover off to access the port. On older VW models (early 2000s), the port may be above the pedals and partially obstructed. Audi vehicles place the port in a similar location with a cover panel, and on some models it is positioned within the center console cubby or near the driver's knee bolster. VW and Audi ports are almost always covered, so do not be discouraged if you cannot see it immediately -- feel for a removable panel.

General Tips for Finding Any OBD-II Port

If your vehicle is not listed above, follow these universal tips. The standard that defines the connector, SAE J1962, requires it to sit in a zone running from the driver's end of the instrument panel to 300 mm past the vehicle centerline, attached to the instrument panel and accessible from the driver's seat without tools. Start by looking directly under the steering wheel, then check to the left and right along the lower dashboard edge. Feel with your hand if the area is too dark to see -- the trapezoidal shape is distinctive. Check for small plastic covers, panels, or doors along the lower edge of the dashboard. On some vehicles, the port is behind the coin tray, in the center console, or near the fuse box. Your vehicle's owner's manual always lists the exact location under the diagnostics or maintenance section.

Right-Hand-Drive Cars: Why the Port May Not Be on the Driver's Side

Everything above assumes a left-hand-drive car, because that is what the US market sells. If you are in the UK, Ireland, Australia, New Zealand, Japan, South Africa or India, the rule still holds in principle but the side flips — and quite often it does not flip at all, which is exactly why the port can be so hard to find. SAE J1962 positions the connector relative to the <strong>driver's</strong> end of the instrument panel, extending up to 300 mm past the vehicle centerline. Read literally, that puts it on the right on a right-hand-drive car. In practice it frequently does not, and the reason is how these cars get built: a model engineered left-hand-drive first and then produced in right-hand-drive form often keeps the dash harness, the bracket and the connector roughly where they always were. The steering wheel moves; the diagnostic connector does not always follow it. So on a right-hand-drive vehicle, check in this order: 1. Under the dash on the driver's (right) side, by your right knee — the position the standard implies. 2. <strong>Under the dash on the left</strong>, near the passenger's knee — the left-hand-drive position the platform may have kept. 3. Centre of the dash, above or behind the console trim, or in the fusebox area — common on models sold in both configurations, because a central position works for either. One more thing worth knowing if you bought an import: a grey-import or personally converted vehicle can have the connector anywhere the converter found room, and it may not follow the market's usual pattern at all. If none of the three positions above turn it up, the owner's manual index under "diagnostic" or "OBD" is faster than searching by feel.

Found the Port but the Scanner Still Will Not Connect?

Finding the connector is only half the job. If the port is right where it should be and your scanner still shows nothing, the next step is measuring it rather than looking for it. Pin 16 should read battery voltage with the key off; pins 4 and 5 should read continuity to ground. If those are good, the fault is usually on the data side — and on any 2008-or-later vehicle the decisive check is resistance across pins 6 and 14 with the key off, which should read about 60 ohms. The <a href="/tools/obd2-pinout/">OBD2 pinout and port tester</a> walks that through: you enter what your meter reads and it works out which protocol the vehicle uses and what is actually wrong — a missing terminator, a broken bus, a short, or simply a blown fuse feeding the connector.
