The second generation of Toyota Allion and Toyota Premio was designated T260 and was produced in 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016. During this time, the model was restyled. In this publication, we will show the locations of electronic control units, a description of fuses and relays Toyota Allion T260 (Premio) with block diagrams and photo examples of their implementation. We will highlight the cigarette lighter fuse.
