The Nissan Almera N15 is the first-generation model produced by Japanese automaker Nissan from 1995 through 2000. It was primarily available as a three-door or five-door hatchback. A mid-cycle refresh in 1998 updated the exterior styling, including the bumpers and side skirts. This guide details the locations, diagrams, and terminal descriptions for all electronic control units (ECUs), fuse boxes, and relay blocks on the Nissan Almera N15. The fuse for the cigarette lighter is highlighted in bold.
