It’s frustrating when the check engine light comes on unexpectedly while driving in Regina. While it’s important to address any underlying issues with your vehicle, there may be times when the light needs resetting after maintenance or minor repairs.

The check engine light is part of your vehicle’s onboard diagnostics (OBD) system. It alerts you to potential problems with the engine, emissions system, or other critical components. Whether you drive a Ford F-150 Lariat or a Toyota RAV4 Limited, it’s essential to take this warning seriously. However, after addressing the issue, you may need to reset the light manually to ensure it stays off. 

Let’s cover how to reset a check engine light and what you need to know about this common issue.

How to Reset the Check Engine Light

Before attempting to reset a check engine light, ensure that your vehicle has been inspected and any necessary repairs have been made. Ignoring significant issues can lead to more costly repairs down the road. Here’s how you can reset a check engine light for most vehicles: 

  • Ensure your vehicle is parked in a safe location and the ignition is turned off.
  • Open the hood and disconnect the negative terminal of your car’s battery. Leave it disconnected for about 10-15 minutes.
  • After waiting, reconnect the battery terminal and ensure it’s secure.
  • Turn the ignition back on and check to see if the check engine light has reset. If the light remains on, it may indicate a persistent problem. It’s best to visit Titan Automotive; your local Canadian dealership near Saskatoon for a professional diagnosis.

Using an OBD-II Scanner to Reset a Check Engine Light

If you prefer a more straightforward approach, an OBD-II scanner is a handy tool for resetting the check engine light:

  • Plug the OBD-II scanner into your vehicle’s diagnostic port, usually located under the dashboard.
  • Turn on the ignition but do not start the engine.
  • Use the scanner’s interface to read the error codes.
  • Once the problem has been fixed, select the option to clear or reset the codes, which will turn off the check engine light.
