This covers most major brands such as Ford, Chevrolet, Toyota, Honda, BMW, Mercedes-Benz, Volkswagen, and many more.

Q: Can this scanner turn off the Check Engine light?

A: Yes! Once you have read and reviewed the diagnostic trouble codes (DTCs), you can use the scanner to clear them and turn off the Check Engine light. Note that if the underlying issue is not fixed, the light may come back on after a short period of driving.
