In 2001, Toyota launched a new family of three-row minivans to replace the TownAce Noah and LiteAce Noah models. Their direct successors were the Noah and Voxy, respectively. Although virtually identical mechanically, the two vehicles feature distinct styling and were distributed through different retail dealership channels. This article provides a detailed overview of the fuse box and relay panel diagrams for first-generation Toyota Noah and Voxy models (chassis codes AZR60, AZR65; MC platform): model years 2001, 2002, 2003, 2004, 2005, 2006, and 2007.
Below you will find the locations and reference diagrams for the power distribution boxes. Fuses for critical components such as the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold text.
