What do the Onix codes 18 and 20 indicate?
Years 2013-2022

Answer

Codes 18 and 20 on the Chevrolet Onix are meant to indicate that your headlights are burnt out and need to be replaced. These two codes may sometimes appear on the display even after you have replaced the bulb, because you have inserted LED bulbs. In this case, you just need to reset the settings by going to the menu of settings.
