Honda Accord 8th generation was produced in 2008, 2009, 2010, 2011 and 2012. The most popular models were the Accord 8 with 2.4 and 2.0 liter gasoline engines. The model was supplied worldwide and is also known as the Acura TSX . In this material we will show a description of the fuses and relays of the Honda Accord 8 with block diagrams, photo examples of their execution and locations. We will highlight the cigarette lighter fuse.
The purpose of fuses and relays may differ from those presented and depends on the level of electrical equipment, the region of installation and the year of manufacture of your car.
