Fuse Box Diagrams Lexus LX570 (J200; 2014-2015)

In this article, you will find information about the fuses of the Lexus LX570 (J200) (models 2014 and 2015), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.

Checking and Replacing Fuses in Lexus LX 570

The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Replace it with one of an appropriate amperage rating. The amperage rating can be found on the fuse box lid.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Lexus dealer correct it as soon as possible.
