To reset the particulate filter warning light that appears on the instrument panel of the Mazda 6, you will need to ensure that the filter undergoes regeneration: to make sure that the regeneration occurs, you will need to drive for a few kilometers keeping the engine always above 3000 rpm. If the light should still remain on after the regeneration, it will be possible to open the hood and access the fuse box: here you can locate the relay shown in the video, which you will need to clean the contacts of. This will reset the sensor that causes the light to come on, making it disappear.
