Rav 4 fuses, where they are and how to replace them

The main purpose of a fuse box is to control loads and prevent short circuits in electrical connections. The elements of the block break the circuit when the electric current (voltage) indicators remain at a critical level for a long time.

Most of the power supply circuits for the electrical equipment of the machine are protected by fuses. Devices that consume large amounts of electricity (for example, a gas pump and electric power steering) are connected via a relay. Failure of these parts can lead to failure of the entire vehicle system, as well as accidental fire.

Toyota RAV4 Fuse Boxes

Sudden surges in current usually occur due to a fault in the circuit (short circuit). Therefore, almost all electrical wiring connecting vehicle equipment has protection elements. The most energy-intensive areas are connected via a relay.

For ease of use, all these current controllers are combined into special mounting blocks, which are located in the passenger compartment and under the hood of the car.

Below are typical diagrams of electrical fuses in blocks for 4th generation cars (from 2012 to the present).

On the website avto-fresh.com you can find a diagram of fuses and relays for Toyota rav4 (2000-2005; xa20), photos and descriptions of the blocks, as well as answers to questions about where it is located and what it is responsible for. The designation of electrical equipment is described in detail in the article.

Additional block

The additional block contains only four fuses. Each of them is presented in the diagrams separately for cases where the steering wheel is located on the right or on the left. Also below is a breakdown of what each element is responsible for.

This element is responsible for the electric drive of the left seat.
The same thing, but for the right seat.
In this case, the element is used to organize the operation of the tailgate.
Fuse for front power windows.

Mounting block

This unit can be found under the dashboard of a Toyota RAV4.

The arrangement of fuses in the block is as follows:

As for the designation and purpose, the decoding of the numbering looks like this:

Designation	Purpose
1	Stop light operation.
2	Opening/closing the hatch.
5	Door lock.
6	Operation of fog lights.
15	Windshield wiper operation.
14	Turn on/off the reversing lights.
20	Turning on/off side lights.
25,26	Heated seats.

The table shows only the most popular fuses. The block also contains elements that are responsible, for example, for the operation of various sensors in the system and the cigarette lighter. They also provide electricity to the car's outlets, control the audio system, heater, and other functions or devices of the vehicle. This also includes fuses that regulate the operation of airbags, the fuel pump and the generator.
