2020 Mazda 3 - OEM Factory Repair Manual

Get the manufacturer’s repair information for your 2020 Mazda 3, including factory service procedures, diagnostics, technical illustrations, and wiring diagrams—in one digital manual made for your exact vehicle. Understand your vehicle. Approach repairs with confidence.

About the Mazda 3

We cover the Mazda3 across the BK, BL, BM/BN and BP generations. Engines include 2.0- and 2.3-liter MZR units, the Mazdaspeed3 2.3 turbo, 2.0- and 2.5-liter Skyactiv-G and the 2.5-liter turbo, with Skyactiv transmissions and i-Activ AWD.

Made for your car, by VIN

The same model can differ by engine, transmission, body, and trim. That’s why we don’t sell a generic file: after payment, you give us your vehicle’s VIN, and we save the matching service information directly from the manufacturer’s official technical information website. You get the information that applies to your car—no guessing between years, engines, or versions.

Factory information you can put to work

Review repair procedures before starting a job (from routine maintenance to major repairs)
Understand component layouts with technical illustrations (procedures are explained step by step)
Follow electrical connections using wiring diagrams
Plan your work and discuss recommended repairs with your mechanic (or double-check a quote)

Illustrations and diagrams keep the original image quality supplied by the manufacturer. The PDF has bookmarks, an index, and working links, so you can go straight to the section you need.

Permanent ownership with no recurring subscription fees—the manual is yours to keep.

About the 2020 Mazda 3

The 2020 Mazda 3 belongs to the fourth-generation Mazda3 (BP), built for model years 2019–2026. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2020 model year.

Check the model year on your VIN: on a 2020 vehicle the 10th character of the 17-digit VIN is “L”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.

At about 6 years old, a 2020 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.

Same generation: 2019 Mazda 3, 2021 Mazda 3.

All Mazda 3 model years: 2006 · 2007 · 2008 · 2009 · 2010 · 2011 · 2012 · 2013 · 2014 · 2015 · 2016 · 2017 · 2018 · 2019 · 2020 · 2021
