Wiring diagram Lada Vesta - Lada Vesta Cross SW

Lada Vesta, like all modern cars, has a large amount of electronics and electrical equipment. In order for this whole thing to work and function properly, the car requires electrical wiring, which, like the veins in the human body, literally permeates the entire body of the car. If we pull out all the wiring of the Lada Vesta and measure its length, we will get a figure of several hundred meters.

The need to study electrical circuits most often arises when an element breaks down or fails. In this case, it is necessary to correctly diagnose and establish the cause of the breakdown - to “sentence” the element itself or the wiring to replacement. Let's look at a small example. The car lost idle speed. The diagnostics revealed an error in the XX regulator. There may be several reasons - either the regulator itself has failed, or poor contact on the wire chips, or a break in the wiring. Before buying a regulator, you need to make sure that the problem is not a broken electrical circuit. We can do this with a tester and test the wiring. But here's the problem. The IAC wires are located under the hood, and control comes from the ECU in the cabin. So what should we do? In this case, the Lada Vesta electrical diagram will help us. Using the diagram, we can find where the contact is coming from the ECU to the IAC and make a call without any problems. This is a seemingly very simple situation, but without knowledge of the Lada Vesta electrical circuit it would not be possible to solve it in a short time.

In this article you will find all the electrical equipment diagrams of the Lada Vesta with a detailed description. So, let's go.

Lada Vesta: Electrical equipment pinout

Modern AvtoVAZ cars are already at the level of imported competitors in terms of the availability of standard equipment and installed auxiliary devices.

The Lada Vesta itself differs from outdated models in the abundance of electronics and increased reliability of the chassis. On the other hand, car enthusiasts often complain about frequent failures of electrical equipment and their weakness when used in domestic conditions.

Consequently, the Vesta pinout is in great demand among specialists or ordinary drivers.

How to increase the service life of electrical equipment

To extend the life of standard wiring, it is recommended to perform certain actions. Periodically check the tightness of the plugs - during active driving, the plastic fasteners may wobble, which can cause a short circuit.

Before active use, treat all detachable connections with special oil. This will prevent their oxidation and deterioration of impulse transmission.

Every year check the condition of the wire braiding - during operation there are strong temperature changes on the main line - this dries out the insulation and stimulates short circuits.

How to avoid connection problems

When repairing or replacing electrical units, some users make mistakes by connecting the wrong terminals, which causes short circuits and burnout of parts. To avoid possible problems, experts recommend studying the location of pins and contact groups in advance, and also marking the contacts yourself before disconnecting them.

Bottom line

The above Lada Vesta pinout is taken from the manufacturer's service documentation supplied with the new car. At the same time, general provisions are indicated - depending on the configuration and year of manufacture, the connection of outputs and the location of units may differ slightly.

If you are unsure of your own abilities, it is recommended not to interfere with the car yourself, but to contact a qualified technician.

Fuse box Diagram and location of Lada Vesta (Lada Vesta)

In any car, sooner or later, the car owner is faced with the inoperability of certain components and assemblies, especially when it comes to electrics. The cigarette lighter may stop working, the lights may go out, the air conditioning may turn off, or the interior lighting may simply fail. Lada Vesta was no exception.

Before replacing a faulty unit, you must check the fuses that protect these circuits. Or a relay. All this is traditionally located in the fuse box, of which the Lada Vesta has two - one in the cabin and the second in the engine compartment.

Let's look together at which fuses and relays are responsible for what and where exactly to go if certain electrical appliances fail in Vesta. Let's start with the interior fuse box.

Location of the interior fuse box of the Lada Vesta:
In order to gain access to the fuse box in the Lada Vesta, we need to remove two latches, this is done as follows:
Congratulations, if you did it carefully, the rivets will remain intact, they are reusable
This is what the fuse box looks like in a Lada Vesta
Let's look at the schematic designation of relays and fuses in the cabin unit on Vesta:
Now let’s find out which electrical circuits are protected by fuses in the block:

Warning
The presence of fuses depends on the degree of electrical equipment of the vehicle.
Interior mounting block relay

On-board computer control algorithm

1. Selection of on-board computer functions (carried out using the keys on the right steering column switch).

2. Selecting trip meters and switching between clock and temperature.

3. Enter parameter setting mode, select parameter.

3.1. Setting the time.

When you exit the time setting mode, the seconds counter is reset to zero (reset without rounding). If there are no button presses within 60 seconds, the time setting mode will exit automatically.

4. Display mode of parameters of the “Cruise control” or “Speed limiter” functions.

In the mode of displaying the parameters of the “Cruise control” or “Speed limiter” functions, it is possible to switch the displayed function of the on-board computer (point 1) and the total and daily mileage counters (point 2), the indication of outside air temperature and time is not available, parameter setting modes (point 3 ) are not available.

“short” – press for less than 1.5 seconds, triggered when released.
“long” – press for more than 1.5 seconds, triggered by time.
yellow color – the segment is blinking (square wave, 1 Hz).
When resetting the route parameters (clause 3(d)), the following parameters are reset to zero: average fuel consumption, fuel consumed, travel time, average speed.

Bookmaker settings are also shown in the video:

To change the sound of the turn signals, you need to go to the secret menu (it does not work on the instrument cluster). To do this, press two BC buttons at the same time. More detailed instructions in the video:

Are you satisfied with the functions of the Lada Vesta on-board computer? Let us remind you that other operating instructions for this vehicle can be found in this section.

It is difficult to imagine a modern car without an on-board computer (alternative names: “BC”, “carputer”, “onborder”), which allows you to increase engine efficiency, reduce gasoline consumption, optimize the operation of the gas distribution system and synchronize the interaction of all units. In addition to the above, BC reduces the concentration of harmful emissions. The onborder performs the functions of cruise control, climate control, and displays the information necessary for the driver, allowing him to make the right decisions on transport management and optimal movement along the chosen route. That is why all modern Lada Vesta models are equipped with BCs that successfully perform the functions assigned to them.
