The fuse box is the hub where all of these fuses are kept, organized, and easy to get to for checking and replacing. This important part was carefully made to make sure that each fuse goes to the right circuit, which makes upkeep and troubleshooting easier. It is important to know how the 2020 Toyota Land Cruiser’s electrical system works by figuring out the layout and purpose of the fuse box and how to read the fuse diagrams that go with them.

After a fuse is replaced

• If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement.
