The first-generation Toyota Auris (chassis code E150; Toyota New MC platform) hatchback was produced from 2006 to 2013 and distributed worldwide. A mid-cycle facelift was introduced during its production run. This guide provides detailed location information for electronic control units (ECUs), along with comprehensive fuse and relay box diagrams and reference photos for the Toyota Auris. The cigarette lighter fuse location is explicitly highlighted.
Note: Fuse and relay configurations may vary depending on vehicle specification and model year. Always cross-reference this information with the diagram on the fuse box cover.
