In 2005, Citroën introduced the C1 small hatchback, developed in collaboration with Toyota and Peugeot. Its sister models are the Peugeot 107 and Toyota Aygo. The vehicle was available in three-door and five-door body styles. All variants feature a front-wheel-drive layout. The model belongs to the A-segment and is characterized by its ultra-compact dimensions. In this article, we will provide a detailed overview of the fuse box diagrams for the first-generation Citroën C1 (TPCA platform; chassis codes PM / PN), covering the 2005 through 2015 model years.
Below, you will find the locations and diagrams of the power distribution boxes. The fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
