Learn How to Reset Check Engine Lights

Discover the Issue and Fix it Right Away

Since you’re here wondering how to reset check engine lights on your car, that likely means that you’ve either already deduced that there’s nothing wrong with your car, or you don’t think the issue is pressing enough to resolve it right now. However, if there is any issue with your car that causes the check engine light to come on, we suggest you do not ignore the problem but instead have it taken care of as soon as possible. If you do not have your car serviced for this issue, it could lead to further repairs down the line. So, if you think there is an issue with your vehicle, schedule a service with us so you can comfortably and safely get back onto Dayton’s streets!

Disconnect the Negative Battery Cable

In the chance that you cannot locate an issue that needs to be fixed and the light is still on, you can manually reset the check engine light. To do this fairly simple process, just follow the steps listed below:

1. Make sure your car is off and that the engine is cool, and equip yourself with safety gloves and glasses.
2. Find the negative terminal under the hood of your car, which will typically have a black cap and a negative (–) symbol on it. The positive terminal should be red with a positive (+) symbol, so make sure you are focused on the right terminal.
3. Using a wrench, loosen the nut on the negative terminal and pull the negative connector out from the battery, leaving it off to the side for upwards of a whole minute.
4. Finally, reconnect the negative cable and use your wrench to tighten the nut back.

Note that doing this could reset your vehicle’s Uconnect (or other infotainment) system. While this should work and keep your check engine light from being on, if it doesn’t, there is another option.

Check Your Vehicle’s Gas Cap

One reason why your vehicle’s check engine light may be on could be due to a cracked or loose gas cap. If your gas cap is faulty, it will release fumes and should illuminate your car’s check engine light. If you have a cracked cap, then you may have to replace it. Otherwise, you can always turn of your car and check to see if the cap is tightened, then turn it back on and see if the light turns off. If not, try disconnecting the battery from the steps listed above and see if that works!
