The relay and fuse box is also called the mounting block or black box. If problems are identified in the car related to electrical equipment, first check the fuses and relays. If they burn out, we replace them with the same ones, but first we must determine the cause of the burnout. The article contains a complete description of all Lada Largus mounting blocks.

The first car of this VAZ family was released in 2011, and already in 2013 it became one of the leaders of the Russian car market, further consolidating its victory in 2014. Among the various options, the Largus Cross crossover is offered, which appeared in various trim levels in 2015 and 2021.
In 2017, it was announced the start of production of Lada Largus on gas, which was implemented in 2021, which also became the year of restyling of the family members. You can buy a car of the family with an 8-valve engine and a 16-valve engine. Unlike configurations, this does not greatly affect the set of fuses and relays that can be found in one of the two mounting blocks of the machine.
The first and main one is located in the cabin, and the second is under the hood, which is quite typical for AvtoVAZ models.

Cigarette lighter fuse Lada Largus - where is it located on the diagram?

The Lada Largus cigarette lighter fuse is the most frequently burned fuse, which can cause a lot of inconvenience. In this material we will look at what fuse is on the Lada Largus cigarette lighter and where it is located.

Where is the cigarette lighter fuse on Lada Largus?

The Lada Largus cigarette lighter fuse is located in the mounting block in the car interior. The layout of the Lada Largus mounting block is shown in the photo:

In order to find a blown fuse, you need to open the driver's door and remove the cover of the mounting block. Next, using special tweezers, you can remove the burnt fuse and replace it with a new one.

In order to understand where the Lada Largus fuse is located, let's turn to the diagram.

The fuse for the cigarette lighter of the Lada Largus is located under number F38. At the bottom of the mounting block it is located in the third row, second from the bottom. In addition to the cigarette lighter, this fuse is responsible for the car's audio system.

What is the fuse for the cigarette lighter of Lada Largus?

The Lada Lagrus cigarette lighter is equipped with a Standard (Norma, Regular, Standart) fuse with a rating of 15A. Such a fuse can be purchased at any auto parts store, as it is suitable for a large number of cars, incl. for almost all AvtoVAZ cars.

Why does the Lada Largus cigarette lighter fuse light up?

If the car's electrical system is fully operational, then a common cause of the cigarette lighter fuse blowing is excessive load on the power wires.

This is due to the fact that the cigarette lighter connector of the Lada Largus is often used as a socket for connecting various accessories - for example, a compressor for inflating wheels, various chargers for gadgets (phone, recorder, laptop, etc.), voltage inverters, etc.

Often these devices consume a lot of current, and the wiring is of insufficient cross-section, so they overheat and the fuse simply blows.

However, if you do not use such devices, and the fuse continues to burn, then there is a short circuit somewhere. In this case, you need to sort out the wiring and only then replace the fuse with a new one.

Most electrical circuits on the Lada Largus car are protected by fuses. Powerful consumers, such as headlight lamps, fan motors, fuel pump and others, are connected through a control relay. Fuses and relays are installed in mounting blocks, which are located in the vehicle interior and in the engine compartment. In this article we will talk about fuses and relays of the Lada Largus, where they are installed, what ratings they should have, and which unit is responsible for powering them.

Most fuses are installed in the fuse mounting block located in the passenger compartment (Fig. 1), at the left end of the instrument panel, under a plastic cover.

In Fig. 1 shows the maximum possible set of fuses. On a specific vehicle, depending on the configuration, some fuses may be missing. The circuits protected by fuses on the Lada Largus car from the end of the instrument panel (shown above) are given in table. 1.

In addition, relays and fuses are located in the mounting block in the engine compartment of the Lada Largus (Fig. 2).

In the mounting blocks in the engine compartment of Lada Largus cars, six panels are used that have symbols corresponding to the symbols on the electrical diagrams. Depending on the vehicle configuration, some of the relays shown in Fig. 2 may be missing. In table. 2 shows the designations of relays and fuses in the mounting blocks located in the engine compartment.

1. To gain access to the mounting block located in the passenger compartment, remove the cover on the left side of the instrument panel.

On the inside of the cover there is a diagram of the location of the fuses. The cover also contains spare fuses A of various current strengths and plastic tweezers B for removing fuses from the mounting block.

2. Before replacing a blown fuse, find out the cause of its blown and eliminate it. When troubleshooting, look at the information listed in the table. 1 circuits that this fuse protects. Do not replace fuses with jumpers, fuses rated for a different amperage, or homemade jumpers - this may cause damage to electrical devices and even cause a fire.3. Remove the fuse to be replaced using special tweezers.Fig. 2. Numbers of relays and fuses in the mounting block located in the engine compartment4. This is what a blown fuse looks like (the jumper inside the holder shown by the arrow has burned out and opened).
