Fuses Toyota Sienta / Porte / WiLL Cypha (NP10 / NCP80 / XP70), 2002–2015

The Toyota Sienta, Porte, and WiLL Cypha are subcompact minivans built on the Toyota Vitz platform. This article provides detailed fuse box diagrams and relay locations for the first-generation Toyota Porte (NP10), Sienta (NCP80), and WiLL Cypha (XP70) produced from 2002 to 2015.

Below are the locations, diagrams, and photos of the power distribution boxes. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold text.

In the Engine Compartment

The main fuse box is located next to the battery, while a fusible link block is mounted directly on the battery terminal. Depending on vehicle trim and optional equipment, additional sub-boxes for the daytime running light (DRL) system and ABS may also be installed in the engine compartment.
