How do I reset check engine light on 2014 chevy cruze?

The only way to reset the "check engine" light in a 2014 Chevy Cruze may be to use an OBDII scanner. But try one of these simpler methods first before visiting a shop. Check for a loose gas cap. When tightened, the light will go off. Drive the car for at least 15-20 minutes above 25 mph. If You've been starting and stopping excessively, the catalytic converter may be stressed and driving at highway speeds should clear the CEL. Turn the key in the ignition to the "on" and then the "off" position three times in succession and try starting the engine. Disconnect the positive battery cable for 15-20 minutes. Reconnect and repeat the previous "on" and "off" steps outlined above. If these methods fail, keep in mind, the CEL warning is indicating there's an issue with the transmission, O2 sensors or spark plugs and get the Cruze diagnosed immediately.
