Where is the 2010 Nissan Altima OBD port location?

I just bought a used 2010 Nissan Altima and the check engine light has already switched on. Where do I plug in the scanner to check what’s wrong?

You’re smart to check it ASAP! For the 2010
Nissan Altima
, the OBD port location—also called the Data Link Connector for Nissans—is located under the steering wheel. You’ll see a trim cover that you can remove to reveal the connector.
The OBD connector in the 2010 Altima is an OBD-2 port, which you might also see written as “OBD-II.” This means you can diagnose your Nissan’s problem with any OBD-2 scanner. Don’t have one? Don’t sweat it—you can typically use one for free at your local chain auto parts store like AutoZone or O’Reilly Auto Parts.
If you have a scanner you can use at home, the most efficient way to read your Altima’s
OBD codes
is to read your user manual. If you lost that, though, the following steps will work for most scanners:
  • Make sure your car is off. Then open the port on your Altima and insert the connector to the OBD port.
  • Turn on your vehicle, then follow any prompts you see on the screen. Depending on the scanner, you may be asked to enter your car’s VIN.
  • Start the scan process by pressing the necessary button, which may say “scan” or “start.” The screen should then reveal any error codes your Nissan is producing.
  • Document the data so you’ll know what to do next to fix your Altima’s problem.
Once you’ve solved the problem, you can typically use the scanner to reset your warning lights, but this process will depend on the specific scanner you’re using.
