Press the “read” button on the scanner and turn the key to the “on” position

A string of letters and numbers will make up the code. Make a note of all the codes so you can figure out what they mean and make the necessary repairs to your car.

While some scanners identify or explain the codes, others do not. Look up the code in the owner’s manual or online if you don’t obtain a definition.

Turn off and disconnect your scanner’s key after pressing the “erase/clear” button

As long as the “erase/clear” button is pressed, the light will stay off. After you release it, the check engine light may turn back on if there are other issues with your car that are causing it to trigger.
