Most electrical supply circuits in this vehicle are protected by fuses. High-draw electrical components—such as headlights, cooling fan motors, and the fuel pump—are connected via relays. Protective components are housed in power distribution boxes located in the engine compartment and the passenger compartment.
This guide provides comprehensive fuse box diagrams for the Toyota Vitz (chassis codes KSP90, SCP90, NCP91, NCP95; B platform; 2005–2010 models) equipped with 1.0 L (1KR-FE), 1.3 L (2SZ-FE, 2NZ-FE), and 1.5 L (1NZ-FE) engines.
