Fuses and relays Toyota Corolla (E180; 2012–2018)

Toyota Corolla E180 represents the 11th generation of the Corolla model range and was produced in 2012, 2013, 2014, 2015, 2016, 2017, and 2018. During this production run, it received a facelift. In this article, we provide a detailed guide to the fuses and relays for the Toyota Corolla (chassis codes E180/E170/E160; New MC platform), including fuse box diagrams and component location maps. The fuse responsible for the cigarette lighter is highlighted in bold.

The exact location and function of individual fuses and relays in power distribution boxes may vary depending on vehicle specification and trim level. Always refer to the fuse box cover diagram on your specific vehicle.
