Honda CR-V 4th generation was produced in 2012, 2013, 2014, 2015, 2016 with different body designations: Rm1, Rm2, Rm3, Rm4. During this time, the model has undergone restyling. In this article, we will provide a description of the fuses and relays of the Honda CR-V 4 with block diagrams, photos and locations. We will note the fuse responsible for the cigarette lighter.
The purpose of fuses and relays may differ from those presented and depends on the year of manufacture, level of electrical equipment and region of supply of your vehicle.
Cabin block
In the cabin, the main fuse and relay block is located under the instrument panel on the driver’s side.
Check the assignment of elements with your diagrams on the block cover.
