Production of the second-generation Citroën C4 Picasso began in 2013, following the debut of the Technospace concept car—the prototype for the new minivan—at the Geneva Motor Show in March of that year. The vehicle utilizes the new EMP2 modular platform, featuring a wheelbase extended to 2785 mm. In this article, we provide a detailed overview of the fuse box diagrams for the Citroën C4 Picasso (second generation; EMP2 platform; B78 code) for the 2014–2020 model years, including the seven-seat Grand C4 Picasso modification.
Below are the locations and photos of the fuse distribution boxes. The fuses responsible for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
