The Toyota Gaia is a five-door, six- or seven-seater minivan built on the Toyota Ipsum platform (a sister model). As a result, the body codes for both the Ipsum and Gaia are identical: front-wheel drive (FWD) models are designated SXM10G, CXM10G, and ACM10G, while all-wheel drive (AWD) models are designated SXM15G, CXM15G, and ACM15G. This article provides detailed fuse and relay box diagrams for the first-generation Toyota Gaia (MC platform) produced from 1998 to 2004.
Below you will find component locations and photos of the distribution blocks. Fuse assignments for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
