These checks follow this Mazda 3's own most-recorded failure strings, starting with what a tester is most likely to flag on a Mazda 3.
the wipers and washers — “wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
the lights — “headlamp aim too high”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
