The second-generation Toyota Previa (Estima), released in 2000, is a standout model in the minivan segment. Unlike its predecessor, which featured a mid-engine layout, this generation transitioned to a front-wheel-drive platform with optional active torque control all-wheel drive. This article provides detailed fuse box diagrams and component locations for the second-generation Toyota Previa / Estima (chassis codes ACR30, ACR40, MCR30, MCR40, AHR10; K platform) covering the 2000, 2001, 2002, 2003, 2004, 2005, and 2006 model years.
Here you will find location diagrams, photos, and assignments for the fuse and relay boxes. The fuses responsible for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
