Original Scion OEM parts catalog. Pick a series and generation to open factory diagrams and genuine part numbers.
Series
This Scion parts catalog is a Toyota EPC-style original parts catalog. It follows the Toyota electronic parts catalog habit: series and generations on this page, then OEM diagrams for the chosen line. English demand is Scion parts catalog; the catalog family behind it is Toyota EPC, not a generic aftermarket index.
In search terms this page is a Scion parts catalog and a Scion OEM catalog: series, generations, and diagrams on one host. Scion sits in the Toyota catalog family, known in workshops as Toyota EPC. Original part numbers are not listed in this text; they appear on the exploded diagrams after you choose a generation.
Pick a Scion series, choose the generation by years, then continue to the 7zap Scion catalog. Toyota EPC-style exploded views and VIN-accurate lookup are reached from that generation. If a series has several generations, use the year range on each card — facelifts are separate when the Scion catalog has them, because diagrams often change there.
In this North America, cars view, the Scion OEM catalog lists 8 series and 10 generations. The lines on this page are tC (2004–2016), xB (2003–2015), iA (2015–2025), xD (2007–2014), FR-S (2012–2016), iQ (2011–2015), iM (2015–2018), and xA (2003–2006). Year ranges are taken from the generations in this filter — the same spans shown on the cards above. If a series has several generations or facelifts, each keeps its own years because diagrams and original part numbers often change between them.
Toyota EPC is built on original part numbers, supersession chains, and exploded assemblies — often with chassis-level structure once you are in the diagrams. That is what this Scion OEM catalog is for. An aftermarket listing may name the model; it will not show the factory layout or the replaced number.
Regions matter in an OEM catalog because the same series can have different generations, years, and diagrams depending on the market. This Scion host currently has one region in the data: North America. The series and generations above belong to that region; a region switcher is not shown because no other region is in the payload. The grid is filtered to cars because that is the vehicle type in this Scion payload for the selected region.
From a generation you go to the 7zap Scion catalog for exploded views and VIN-accurate lookup. That step stays on the Scion OEM path: the same series and generation, with factory diagrams.
