Where is the 2020 Chevy Silverado’s OBD port location?

I’m driving my sister’s 2020 Chevy Silverado while she’s out of town, and the Check Engine light came on yesterday. I don’t have the money to take it to a mechanic, but diagnosing the issue shouldn’t be too hard. Where is the OBD port?

We like your enthusiasm, but proceed cautiously! The OBD port location in a 2020
Chevy Silverado
is under the dashboard, near the steering column.
You probably already know that the Onboard Diagnostics II (OBD-II) port helps monitor your sister’s Chevy’s emissions, engine, and transmission performance. It will allow you to access the vehicle’s internal computer for running tests and diagnostics.
Now, for a few words of warning: it’s important to have the correct tools and follow instructions so you don’t damage the vehicle’s system while running a diagnostic.
First, you’ll need an OBD-II scan tool. Then, follow these instructions to
read any codes
  • Plug the scan tool into the Chevy’s OBD port
  • Turn on the scan tool and crank the ignition in the Chevy
  • Press “Scan” on the scan tool and follow the directions on the screen
Keep in mind that all scan tools are different, so be sure to follow your scanner’s specific instructions carefully. If all goes according to plan, the scanner should provide you with a Diagnostic Trouble Code (DTC) to help you find out what’s wrong with your sis’ ride.
Best of luck!
