The Mazda 5 minivan has been produced in two generations since 1994. We will show the location of all the electronic control units of the Mazda 5 for cars manufactured in 2005, 2006, 2007, 2008, 2009, 2010. We will consider in detail the diagrams of the fuse blocks and relays of the Mazda 5 with a description of the purpose of their elements. We will note the cigarette lighter fuse.
Check the assignment of the blocks with your diagrams on the protective cover.
