The third-generation Mazda 6 Mk3 (GJ/GL) (2012–Present) is Mazda’s handsome SkyActiv-era saloon and Tourer estate, blending efficient petrol and diesel engines with a premium-feeling cabin. After servicing, several electronic systems expect resetting. The oil service reset clears the maintenance message from the multi-information display once fresh oil is in — a particular point on diesels, which track oil dilution. A TPMS reset relearns tyre pressures after a rotation, the brake pad wear warning needs clearing when new pads are fitted, and a steering angle calibration follows alignment work. Disconnecting the 12V battery resets clock, audio and idle learn. Choose the reset routine that matches your Mazda 6 from the procedures listed directly below.
