How to Reset Check Engine Light

check engine light on

Let’s say you’ve gotten your vehicle serviced, but the check engine light is still glowing on your dashboard. What’s going on? You could always call the service center to get the problem solved. However, you can also reset your check engine light by hand if you’d prefer. Follow our guide to determine how to reset a check engine light, and visit Dan Cava's Buick GMC for more service tips.



Before You Reset Your Engine Light

If your check engine light is illuminated, it’s important to get to the bottom of the issue. Some drivers simply want to turn off the light and delay a trip to the service center, but this can cause bigger problems down the line. And sometimes, the issue is as minor as a loose gas cap! We recommend scheduling a service appointment, so our expert technicians can perform quick and accurate diagnostic services at your convenience. After the problem has been resolved, they will turn off the light for you.

Steps to Reset Your Engine Light Manually

If you had the issue professionally resolved and your check engine light refuses to budge, you can also reset your engine light manually if you don’t want to make the trip back to the dealership. Learning how to reset your check engine light by hand just takes a few minutes:

  • Put on safety glasses and gloves.
  • Park in a well-ventilated area and turn off the ignition.
  • Look for the negative battery terminal with a black cap and a negative (-) symbol.
  • Loosen the negative terminal bolt and pull the negative cable from the battery.
  • Hold the cable away from the battery for between 30 to 60 seconds.
  • Reattach the negative cable and tighten it again with your wrench. 

Keep in mind that this will reset all of the electronic systems in your car, which includes your infotainment system. You may need to reprogram your information when you start the car back up again.
