Replacing the fuse box of a VAZ 2110 injector 8 valves

An important component in every car is safety. In addition to seat belts, the car itself must have a protection system so that a short circuit does not result from the car burning out. The car is a complex device of mechanical and electronic systems that ensure trouble-free operation of the car and comfort inside the cabin. The well-known injector cannot function without electricity and a control unit, and many electronic and mechanical components are involved in its operation.

The injector allows you to achieve high fuel economy without loss of power, even on cars with an 8-valve gas distribution system.

Replacing the fuse mounting block

The fuse mounting block on VAZ 2110, 2111 and 2112 cars is located in the lower left part of the instrument panel, where you must first open the cover by pressing the button. You can handle the rest without any problems, having just a couple of screwdrivers on hand: flat and Phillips.

So, when the lid is lowered down, you can unscrew one fastening screw, which is clearly shown in the photo below:

Then we remove the metal retainer. After this, we disengage the block body, as shown below:

All that remains now is to disconnect all the wires that go to the fuse box by lifting it up:

Now you need to use a flat-head screwdriver to disconnect the plugs from the relay:

And after that, you can freely remove the VAZ 2110 fuse box from the instrument panel, since nothing else holds it.

If necessary, we buy a new one and install it in the reverse order, connecting all the wires and relays. The price of a mounting block for a VAZ 2110-2112 is about 2,500 rubles, but a used one can be found at half the price.

Repair

Repairing the VAZ 2110-2112 fuse box is necessary in some cases, of which there are only two:

The first most common problem is combustion. If this happened, it means that the fuses were not in order, which subsequently led to damage to the unit. Many inexperienced car enthusiasts, when they discover a burnt fuse, replace it with a non-standard metal object, which can subsequently create an additional defect.
The second probable reason for changing the unit is a manufacturing defect. In most cases, no problems arise, but in order to save money, drivers often purchase parts from unreliable suppliers at reduced prices and, as a result, end up with a burnt-out power supply system.

You should not purchase a fuse box for a VAZ 2110-2112 made in China; it is better to buy a proven brand, which will most likely pay for itself in terms of service life and trouble-free operation.

The mounting fuse block for the VAZ 2110-2112 is not particularly expensive compared to other important parts. It is better to purchase a high-quality model and install it yourself to be sure of the reliability and performance of the device.

In conclusion, I would like to note that the fuse box is one of the main and very important parts for the operation of the car, which is also responsible for the safety of passengers.

Removing the mounting block: work order

1. From the battery, it is necessary to disconnect the wire from this terminal with a negative terminal sign.

2. Next, you need to slightly open the cover of this vehicle mounting block, then unscrew the screw securing it with a Phillips screwdriver.3. Then you need to pull out the fuse box by pulling it towards you.

4. Then it will be necessary to detach the blocks with attached wires from the block.

5. Next, it is recommended to tie the existing wires with insulating tape into a flagellum.

6. Finally, you will need to remove the cover of the mounting block, while unscrewing a couple of screws securing the bracket hinges.

They also recommend: marking the terminal blocks with the wires pulled out - this action will greatly facilitate the work during subsequent reinstallation and installation of a new one.

Fuse blown

Sometimes the device does not need to be replaced. It is enough to change the fuse located inside the device itself. The procedure is carried out as follows.

Open the hood and remove the negative terminal from the battery. You can also remove the fuse from the mounting block that is responsible for the cigarette lighter of the VAZ 2110.
We unscrew the four fasteners of the tunnel covering and remove both parts of the lining.
Disconnect the three-pin plug going to the cigarette lighter.
Remove the lining under the handbrake lever.
Remove the gearshift lever cover.
We move the seats back, and then unscrew the three fastenings of the upper part of the tunnel and remove it.
Pull out the cartridge.
Use a flat-head screwdriver to pry the cigarette lighter latch so that it comes out of the seat.
We remove the nest from the cladding for subsequent repairs.

Inside the cigarette lighter is a miniature mica plate. It is a semiconductor that sometimes breaks and melts. It needs to be removed. After this, it is worth assembling the unit and then checking the functionality of the device.

VAZ 2110 fuse box: its purpose and replacement

VAZ 2110 fuse box

The VAZ 2110 fuse box can be replaced independently. However, replacing it is not too difficult. All parts of the block can be easily replaced, as they are easily removed. And to replace, you only need to remove the old part and install a new one in its place. In addition, the unit is quite affordable, as it can be purchased at many auto parts stores. But it is expensive, although its design is striking in its reliability, which increases its “viability”. During the replacement process, you definitely need a VAZ 2110 fuse diagram.

Functions

Where are the fuses for the VAZ 2110?

The fuse box has few functions, but they are all very important. And even if at least one of them breaks down, it will lead to a problem with the entire car. Its functions are as follows:

 All fuses are inserted into it. What are fuses? They protect the machine's electronics from short circuits.

Note: If just one fuse is in poor condition, it can cause the entire fuse block to fail. Therefore, the car owner must monitor their performance.

Why doesn't the cigarette lighter work?

On the VAZ-2115 the device stops working due to the following reasons:

Fuses blown. The cigarette lighter in domestically produced cars often shorts out, and the protective parts have to be changed regularly. This is considered a design flaw that is difficult to eliminate.
Connecting too powerful devices to the socket. Burnout is caused by the insertion of a plug into a car vacuum cleaner or compressor.
Changing the state of the nest. With frequent use, it becomes loose, the block dangles, which provokes a short circuit. In this case, the fusible protective elements quickly burn out. The absence of a beep helps determine the malfunction (the fuse-link is loaded with sound devices).
Fan motor short circuit. Standard devices are unreliable and quickly break down. In this case, the cigarette lighter does not work on the VAZ-2115.
Burnout of the track in the installation block due to a short circuit. When the pads are exposed to moisture, the contacts become covered with an oxide film. The fuse box is the weak point of a domestic car.

Causes of failure

There are also not many reasons for breakdowns. There are only two of them:

Defect due to production. Quality companies do not allow their products to have any flaws. Therefore, defective goods are sorted and thrown away. However, Chinese firms neglect this.

Note: Without wanting to install a low-quality unit on your car, you should pay attention to it at the time of purchase.

In addition, the unit may fail due to the fact that a short circuit has formed in the system. But it happens because the fuses are not in order. However, choosing high quality fuses (see VAZ 2110: how to replace fuses) for your car is not as easy as it seems at first glance. Recently, you can increasingly find fuses from “left-wing” sellers. You should avoid them.

Installing Blade Fuses

Such fuses are much better than conventional ones, as they have many positive properties. They have better contact with the socket into which they are inserted. Due to this, they retain their positive qualities for a long time, so they are not in danger of melting or heating. To install them you need to have:

A screwdriver that can be used to remove the terminals.
Key for 8
Heat shrink
Female connectors
Block
Wire to make jumpers

The installation itself is carried out as follows:

Disconnect the negative terminal of the battery so that a short circuit does not occur in the system.
A size 8 wrench will allow you to easily unscrew the fasteners from the block.

Note: It is very important that the wires do not fall off the terminals.

When the block is unscrewed, it must be weighed down until it stops. But you need to act carefully so that the wires do not break.
Make jumpers.
Install blade guards.
Return everything to its place.

Denominations

The fuses themselves are usually sold along with the fuse box. They may be different. The smallest denomination is 5A. At the same time, the largest fuses are rated 25A, but they are not suitable for tens. For the VAZ 2110 it is ideal to use fuses with ratings of 8A and 16A. However, they are not easy to find. Therefore, you need to use those whose denomination is the closest. It is better for it to have a smaller digital value than a larger one.

Replacing the fuse box

To replace the unit, you must perform the following steps.

Note. Some of the work is done in the house. It is advisable to sit comfortably at the table. Jumpers need to be prepared.

Take a thin wire and cut it into 6 equal parts. One segment must be at least 10 cm.

Note: if the top ten does not have a heated rear window function, then you will only need 5 pieces.

All pieces need to be crimped and heat-shrinkable.
Now you need to choose the right diagram for how to insert jumpers. There are many of them on the Internet and in car magazines.

Do-it-yourself repair of the VAZ 2110-2112 fuse box

The injector allows you to achieve high fuel economy without loss of power, even on cars with an 8-valve gas distribution system.

Fuel system.

If the starter in the car is spinning at full strength and a good spark is observed in the ignition system, then possible problems with starting the engine may be associated with the fuel system.

If your car is equipped with electronic fuel injection, then several of its subsystems may specifically cause the power unit to fail to start.

True, it should be noted here that in most of these cases you simply will not be able to independently diagnose all kinds of electronic systems and subsystems, which may actually be the reason for the failure to start the engine. The point is this: this check requires special diagnostic equipment, which is only available in car service centers or car service dealerships.

True, there are some moments when you can check certain subsystems yourself in a garage. And all this thanks to certain and specific methods of such checking. Although you will not find the specific cause of the breakdown, in any case you will significantly narrow the scope of the search for this malfunction, which will save you a lot of money when you go to a car service for electronic diagnostics of the car.

— Electrical connections: There are many electrical connections in the fuel injection system. Each fuel injector has its own connector on top. There are electrical connectors in the air system of the car, as well as on the cylinder head. You should check all the electrical connectors that are under the hood of the car. This is quite difficult, we understand, but nevertheless, you will save a lot of money on this, which you can then give to a car repair shop without regret.

— Fuel pump and relay: To check the fuel pump you will need special equipment that diagnoses the vehicle's fuel system (pressure). Since most of us motorists do not have this kind of equipment, all we can do ourselves is to completely check all electrical connections.

For example, check the flow of electrical current on the positive wire that powers the fuel pump itself. To do this you need an electrical tester. Before checking, make sure the ignition key is in the “On” position. If the tester shows that current is flowing to the pump, then proceed to the next troubleshooting step. If there is no current and does not flow, then you need to check the fuse. If the fuse is in good condition, then the problem with starting the engine is in the fuel pump relay itself. Replace this relay with a new one.

— Fuel filter: If the fuel pump is working correctly, this does not mean that fuel is getting into the engine in the normal sufficient quantity. For example, due to this fuel filter, fuel may not flow into the combustion chamber in sufficient quantities, which may cause the power unit to fail to start. In order to avoid such problems, you need to change the fuel filter in your car every 20 thousand kilometers, which can be heavily contaminated with enzyme-forming substances present in the fuel itself.

You can easily check all these elements in the car yourself and, if necessary, replace them yourself, specifically using everyday auto tools. Unfortunately, there are many other fuel electronic systems that simply cannot be checked without the use of special equipment. Therefore, remember, our dear motorists, to do electronic diagnostics of a car, it is best to trust specifically to professionals and contact a car service center.

Component functions

Each element of the block is responsible for its own electronic unit. A blown fuse or damaged element can lead to malfunction of the vehicle's lighting system, power system and other volatile devices.
Each electronic device in a car unit plays a very important role. If you suspect a malfunction, it is necessary to change it as soon as possible, so that on the road the car does not present you with a surprise in the form of a malfunction.
If the car does not have an injector, but a carburetor, then the car will be able to work with a damaged or inoperative fuse block, but there will be no idle speed and other components may not function fully.
When the unit burns out, the central locking and alarm system stop working, so the car must be parked in a safe place during this time.

Removal and disassembly

The fuse box on a VAZ 2110-2112 car can be changed on your own. The procedure is not difficult; even an inexperienced car owner can do it if desired. Each element of the block is replaceable.

First, remove the block cover. In some fuse boxes, a special button is responsible for removing the panel. The change is carried out by removing the unusable part and installing a new one of the same rating.

Make sure that the circuit of the part being replaced matches the new one, otherwise the new one may also deteriorate and lead to additional elements in the circuit. Before starting work, check the manufacturer's description of the unit to ensure all disassembly is performed correctly.

If the fuse box is completely burnt out or damaged, it can be replaced with a new one. This part is affordable today and can be bought at any spare parts store for VAZ cars.
