Tesla Model S is a five-door electric car manufactured by the American company Tesla, which is designed on a common basis with the Tesla Model X. Therefore, these models have similar electrical circuits. In this article, we will present a description of fuses and relays Tesla Model C / X with fuse box diagrams and their locations for models produced in 2012, 2013, 2014, 2015, 2016.
There is no one general description of fuses and relays for all Tesla Model C and Tesla Model X models, we will only present the most common option. The purpose of the fuses and relays may differ from the one shown and depends on the year of manufacture, the region of delivery and the level of equipment of your car. Check the information with your technical documentation.
The diagrams is wrong or the wrong year of manufacture? Study this post.
In front of the car, under the hood, there are 3 main boxes with fuses and relays.
