The cigarette lighter of the VAZ 2112 16 valves does not work reasons

Modern cars are equipped with one or more connectors. However, they have long been used for purposes other than their intended purpose. Car owners connect additional devices to the car cigarette lighter socket. Among the most common:

fan;
portable electric compressor that pumps up car tires;
traffic recorder;
navigation system;
charging device for electronic devices (phone, tablet, laptop).

Therefore, if the cigarette lighter stops working, this is fraught with inconvenience and hassle. Information on why the cigarette lighter on the VAZ 2112 model does not work, how to identify the cause of the malfunction and carry out repairs can be found in the article.

Why the VAZ-2112 cigarette lighter does not work and how to fix it

A modern car is always equipped with a number of additional and completely optional gadgets and gadgets. But over time, some of the additional attributes have become so familiar to drivers that their presence seems necessary. The cigarette lighter has a similar story. Although this device is designed to replace a lighter, the socket itself can be used for a variety of purposes (from charging your phone to connecting a portable refrigerator). Such operation often leads to damage to the cigarette lighter. This is a very common problem, along with a breakdown of the radio, a malfunction of the dashboard, and other troubles of the same type. They are all electrical related, so the root of this problem is a little similar.

The cigarette lighter on the VAZ-2112 does not work: causes and repairs

Regardless of whether the injector has 8 or 16 valves, the methods for checking and repairing the cigarette lighter are similar.
Everyone knows how to use it, even non-smoking drivers. But how to conveniently check why it stopped working is a more complicated question. If the cigarette lighter on a VAZ-2112 does not work, you do not need to immediately run to a service center and order new wiring. A heating system can be used. If the fan works, then the problem is not in the wiring, but in the cigarette lighter itself (or the fuse). Since both of these devices are battery powered, they have a common fuse. If the fan does not work, it means there is a problem with the fuse (in the operating instructions it is indicated as F18).

This is a simple option, and a simple breakdown. It is quickly checked and easily corrected. In addition to this simple case, the trouble may also be in the wiring.

If testing shows that the fan is working, then there is no power. This indicates a wiring problem.

Installing an additional cigarette lighter

VAZ 2110 how to connect the cigarette lighter

For some people, one cigarette lighter is not enough, so they need another one - an additional one. It can be installed under the cover of the on-board control system connector, as there is enough space there. Of course, you can do this in another convenient place.

VAZ 2110 does not work from the cigarette lighter

Instructions:

Make a small hole under the connector cover.

Note: It is important that you have access to the factory cigarette lighter wires. It will be much less hassle if you combine the additional one with the standard one

If it is located far away, then a long wire can be used to connect them.

Connect the wires of the additional cigarette lighter with the wires of the standard one. The colors must match each other.

VAZ 2110 no cigarette lighter light

Note: it is imperative to put it through a fuse, which will protect against spontaneous combustion. In principle, a 10 A fuse is enough. Even this will prevent a short circuit.

Place the additional cigarette lighter in the hole already made and secure it.

How to connect a device to a cigarette lighter without a plug

VAZ 2110 connecting the cigarette lighter

It is not always possible to have a plug at hand that will allow you to connect an electrical device to the car’s cigarette lighter. However, you can make a plug yourself:

Remove the case from the phone.

Note: the case must be leather.

Take two wires and insert them inside the case.

Note: There are usually small holes in the corners of the case. If they don’t exist, then you need to make them yourself. The wires need to be inserted exactly there.

The plus is located in the center of the case, so the positive wire must be twisted towards the center.
In this case, the negative wire should be clamped in the opposite direction (when the cover is completely screwed in).
Insert the resulting plug into the cigarette lighter.

How to check your cigarette lighter for problems

First of all, you need to visually inspect the wires that go to the mounting block (through them the cigarette lighter receives current from the battery).
In addition to inspection, you also need to check the connectors of the connections - they must “fit” tightly. It happens that they become separated.
Special attention should be paid to electrical connectors. They are located approximately in the same place as the passenger's left foot.
If there are problems with the wires, then you need to replace them (you will need new wires, electrical tape, a utility knife for stripping the insulation, rubber gloves).

So, two of the three possible causes of failure have already been considered. There is one more thing left - the cigarette lighter itself is broken, but all the systems that ensure its operation are in order (it is advisable to check all the reasons, since there can be several breakdowns at once).

From the very beginning, you should remove the button with a flat-head screwdriver (insulating the rod with electrical tape). There are special “antennae” that you need to bend with it. The button should then be firmly fixed. If the problem is not in the button, you need to climb further.
We remove the panel near the gear lever and gain access to the cigarette lighter panel itself.
Take something to catch it with (in the upper left corner) and remove it. There you can see two plugs on which the wires are connected. They also need to be inspected and, if necessary, replaced; all parts of the cigarette lighter also need to be inspected.
There are several methods for removal, but it is better to use the one indicated in the operating instructions. It is more reliable, and if the driver has never repaired such malfunctions on his own, it will be better suited.

Having figured out why the VAZ-2112 cigarette lighter does not work and how to fix it, we can confidently say that this is not a reason to contact the service. It is quite possible for the driver to perform these operations himself, armed with a description of this process.

What is a cigarette lighter and where is it located?

To put it simply, the cigarette lighter socket is the simplest socket that has voltage. On such brands of cars as VAZ 2112, VAZ 2115, VAZ 2110, it is no more than 13 volts. Basically there is one nest. But on more modern and foreign-made Toyota Corolla and Renault Logan cars, their number can increase to two or three.

The design of this part is quite simple, so there are no difficulties during its operation.

Replace fuse

Connecting any electrical device is simple and without additional effort. The main thing is that it has the appropriate connector. This process is often compared to plugging a plug into an outlet.

But, like any other device, the cigarette lighter has its own characteristics. It is very important to take them into account when using it. Otherwise, you may encounter problems with it breaking. This is typical not only for domestic cars VAZ 2112, VAZ 2115, VAZ 2110, but also for many other newer ones.

Any breakdown in a car causes a lot of inconvenience to its owner. Even if at first glance it is not significant, and does not affect his overall work. But it may result in a malfunction of another device. Thus, for VAZ 2112, VAZ 2115, VAZ 2110 cars, the cigarette lighter and radio tape recorder have stopped working. They are interconnected, and this is more serious and it will not be possible to postpone solving the problem.

Is there a standard cigarette lighter?

VAZ 2112 models that came off the assembly line are equipped with long, old-style instruments. Their disadvantage is that they do not provide reliable fixation of connected devices that are designed to meet European standards. As a result, cigarette lighters sometimes short out and refuse to work correctly.

Many owners decide to replace the device on the 2112 with a new device (see photo). The cost of such a cigarette lighter ranges from 600 to 1.5 thousand rubles. Too low a price indicates low-quality materials used in the production of the part. Therefore, you should discard such elements; they will quickly break.

Reasons why the cigarette lighter does not work

There are several situations why a device may fail. The most common reasons why the VAZ 2112 cigarette lighter does not work:

short circuit;
broken cigarette lighter wiring;
blown fuse;
weak contact;
faulty spiral;
burnt out backlight bulb.

Each breakdown situation is discussed in detail below.

The fuses on the cigarette lighter are burning

If the device on a VAZ 2112 stops working, then a burnt-out protective element may be the cause of the malfunction. The vehicle circuit in this area is protected by a 25 amp fuse. This means that devices with a total power of more than 300 W (12 volts * 25 amperes = 300 watts) cannot be connected to the cigarette lighter socket.

Otherwise, the protective element will burn out. A hint that it is the fuse that has “gave up” is the failure of the heater fan. If it does not work, it should be replaced. The location of the mounting block is to the left of the steering column, behind the decorative panel trim.

The element with index F-18 must be replaced. The fuse rating is 25 amperes. It is prohibited to install parts designed to carry high current. This may lead to short circuits, damage to wiring cables, and fire.

Broken or shorted wiring

You need to check where the fuse for the cigarette lighter of the VAZ 2110 is. If it is intact, but often burns, then you should check the serviceability of the cables. Due to a mismatch in the rating of the protective element or connecting too powerful devices, the wires may burn out, which causes a short circuit or damage to the cigarette lighter.

For diagnostics, you will need a multitester, which needs to ring all the wires suitable for the element, finding out their condition.

It's a matter of contacts or filament coils

Over time or due to intensive use, the connection inside the device on the VAZ 2112 may be broken. Incorrect connection of devices leads to loose sockets and poor contact. This can be treated by bending the metal tendrils on the cartridge and resoldering it.

With age, oxides or rust appear on the cigarette lighter, which has a bad effect on its operation. The situation can be corrected by treating the contact areas with a needle file. It is necessary to clean them and remove all traces of corrosion. Another malfunction is a burnt-out nichrome spiral. It is recommended to replace the device here.

Backlight

Around the socket itself there is a special light element that allows you to find the device in the dark. The backlight may stop lighting due to a broken filament. In this case, it is necessary to dismantle the cigarette lighter, remove the faulty element and replace it with a new light bulb.

Causes of malfunction

Before starting the repair, it is necessary to correctly determine the reason why the cigarette lighter and radio in the 2114 do not work. The most common one is related to the additional devices that are connected to it.
Of course, this may sound ridiculous, since it is used directly for such purposes. But it is necessary to take into account the capabilities of the cigarette lighter. Each of them is able to withstand a certain amount of power. And if you use devices that are much more powerful, then this will cause its breakdown. Among the main reasons why the cigarette lighter and radio do not work in the VAZ 2114 are the following:

Connecting very powerful devices to it. For which this indicator exceeds several times the permissible standards for a fuse. It's quite easy to calculate. You can use this simple formula: multiply the maximum current value by the voltage of the on-board circuit. For example, 10 A at 12 V equals 120 W. This value is very important; if it is not taken into account, then repairing the cigarette lighter will become commonplace;
The fuse has blown. This is a consequence of the first reason. It is checked first in case of problems with the operation of the device. The design consists of several fuses: 15A and 25A. The first is responsible for the cigarette lighter itself and the portable lamp socket, and the second for the unit that controls the heating and ventilation process in the car, the light bulb that provides light in the glove compartment, and the radio. According to the diagram, they are connected through the cigarette lighter. And when it fails, the others also malfunction.
Oxidation of device contacts. To eliminate the damage, it is necessary to clean them. But first the mass must be reset. If this is not done, a short circuit may occur. This procedure is not difficult to do, so any car owner can handle it;
Connector oxidation. It is also cleaned and, in very rare cases, replaced with a new one;
Shaking the nest. This occurs quite often, especially if the additional device is poorly inserted into the cigarette lighter. Thus, the contact with its walls is weak. This leads to a short circuit and the contacts melt. As a result, the cigarette lighter and radio in the VAZ 2112 do not work. To fix the problem, you will need to clean and resolder the contacts or install new ones;
The coil in the cigarette lighter has burnt out. There are several ways to fix this problem: installing a new part or repairing a broken one. The second option is used only if the first one fails. For example, a new part is very difficult to find and purchase. The repair consists of cleaning the spiral from contaminants that have formed on it.

The coil itself in the cigarette lighter heats up in less than 25 seconds. If significant changes are observed at a given time, then disturbances have occurred in its operation. It is necessary to correct the situation immediately so as not to lead to other more complex consequences. To do this, the circuit is adjusted by extending or bending the contacts in the device itself. If T

If any measures did not bring the expected effect, then it is necessary to take more significant measures: replace the part with a new one.

Results

By looking at the photo of the device diagram, you can understand why the cigarette lighter and radio tape recorder work together. This also explains their failure together. Therefore, it is very important to monitor the operation of the main element so that others do not suffer.

If problems arise, you can solve them on your own. But, as practice shows, it is better to immediately contact specialists. They will fix the problem much faster and more efficiently. Especially if this applies to modern cars such as Toyota Corolla, Renault Logan and others. Since they have many nuances that must be taken into account when repairing any part.

Diagnosing cigarette lighter problems

If malfunctions occur, the device should be inspected to determine the cause of the failure.

Turn on the heater fan. If it does not work, then the VAZ 2111 cigarette lighter fuse located in the mounting block has blown.
We inspect the contacts on the device itself and its socket. If there are oxides or rust, remove them with a file.
Visually inspect the cables coming to the device for fractures or breaks. We test the wires using a multitester. We turn it on for resistance, and then check each of the three cables coming to the device.

After identifying the problem, you can begin to repair the device.

VAZ 2110 cigarette lighter connection diagram

Before interfering with the circuit, you should understand the pinout. Three wires come to the device.

Red is the positive contact, responsible for heating the coil. Powered by a battery through a fuse with index F18 (common for models 2110, 2111, 2112).
Yellow – backlight, positive contact.
Black – permanent negative wire. A mass connected to the device body at one end, and to the car body at the other.

Cigarette lighter of VAZ 2110 is closed

If the device fails, then you should look for the causes of the failure. It is quite easy to find out that there is a short circuit in the circuit.

Turn the key in the ignition switch, turning it off.
We measure the voltage of the battery when it is turned off.
We turn on the ignition, and then measure the voltage again. If the indicator drops more than 0.5 volts, then there is a breakdown somewhere.

To find out the location of the break, you should arm yourself with a tester and ring all the wires for integrity. You can first visually inspect the cables - there should be no creases or breaks. Additionally, it is necessary to check the tightness of the cartridge in the metal connector. A loose device can also cause a short circuit.

Repairing a broken cigarette lighter

Sometimes replacement is not necessary. In some situations, you can carry out repairs yourself. Inside the car cigarette lighter itself is a small mica plate. This is a semiconductor that often fails. It needs to be removed. After this, it is worth assembling the device and then checking that it is working correctly.

Often you just need to treat oxidized contacts or solder fallen wires.

Instructions for replacing the backlight lamp

If you need to carry out this procedure, then you should act according to a certain scheme.

Turn off the ignition, and then remove the wires from the battery.
To get to the lamp, we dismantle the plastic lining inside the cabin.
Disconnect the gearbox and parking brake housing.
We take out the car cigarette lighter along with the backlight.
Squeeze the screen to remove the metal tendrils.
We rotate them 90 degrees, and then remove the lamp from its seat.
We install the new element, and then carry out the assembly. When connecting, you should use A 12-4 lamps.

A detailed video on how to remove a VAZ 2110 model device with your own hands is presented above.

Removing and replacing the cigarette lighter

Before repairing, you will need to stock up on suitable tools. Required:

Phillips and standard screwdriver;
protective gloves.

To fix breakdowns you will need:

multitester;

What does a cigarette lighter consist of and how does it work?

The device on the VAZ 2112 has a simple design. The cigarette lighter consists of two parts - a metal tube, inside of which there is a nichrome spiral, and a seat for it (socket). The plus is connected to the bottom, and the body is connected to the car body or ground.

When you press the insert, the cigarette lighter starts working: the contacts close and the coil heats up. When the temperature reaches its maximum value, the thermal relay is activated and the device snaps into its original position.

.
Even those who don't smoke still use it.
The most common device plugged into the cigarette lighter
is a mobile phone charger.
Usually the battery runs out at the most inopportune moment, during a very necessary conversation, and what disappointment comes when the phone plugged into the cigarette lighter
says “no charging.”
To prevent this from happening and for the cigarette lighter
to work properly, you must follow some rules.

Do not put compressors for inflating tires into the cigarette lighter socket. They are best connected directly to the battery. And other devices that consume a lot of energy.

There’s no need to forcefully tamp down devices that don’t fit there.

do not put metal objects into the cigarette lighter socket, and try not to buy devices that have metal rings on the body (they can come off and short the contacts inside the socket)

If, nevertheless, the cigarette lighter socket does not produce the desired voltage, then first of all you need to check the fuses, it is called CIG. If it burned out, and after replacing it the energy source began to function, you are lucky, don’t do that again.

If the energy flow is not restored, you will have to disassemble the cigarette lighter itself. If you have not yet believed me, and doubts gnaw at you, you can check the veracity of my words. Reach to the back of the cigarette lighter socket, remove the connector from the socket and connect the light bulb there, and turn the key to the ACC position. If it burns, then a showdown cannot be avoided, and in vain they didn’t believe me.

Repairs will require small pliers, hands, and a small file. We see the back of the cigarette lighter, and are in no hurry to unscrew the nut! Before unscrewing the nut and disassembling the structure, it is advisable to remember in what position the contacts are located and what is positioned. So as not to disassemble again when connecting the connector. After unscrewing the nut, we separate the metal parts from the plastic and disconnect the pieces of iron. And we see an incomprehensible semiconductor-mica plate that ruins our life. We tear it out, throw it away, and try to put everything back together. But we can’t put it back together, so we take a file in our hands and grind off the excess metal that is in our way. After removing it, put everything back together in reverse order, it should work. We put the cigarette lighter back in place and enjoy the fact that we were able to fix our car ourselves.

How to check your cigarette lighter for problems

First of all, you need to visually inspect the wires that go to the mounting block (through them the cigarette lighter receives current from the battery).
In addition to inspection, you also need to check the connectors of the connections - they must “fit” tightly. It happens that they become separated.
Special attention should be paid to electrical connectors. They are located approximately in the same place as the passenger's left foot.
If there are problems with the wires, then you need to replace them (you will need new wires, electrical tape, a utility knife for stripping the insulation, rubber gloves).

Where is the fuse box?

First of all, to independently replace and diagnose electrical fuses, you need to know where exactly the corresponding mounting block is located. The unit with protective elements has its own diagram, thanks to which it is very easy to understand for which consumer is responsible for each element. In VAZ 2112 cars, the injector 8 or 16 valves, fuses and relays are located in two mounting blocks. It is worth noting that both blocks are located in such places that to replace elements there is no need to dismantle any additional components. First, the main unit is located on the right side of the dashboard.

Main compartment location

Second from the left at the feet of the passengers on the center panel.

Utility compartment location

Cigarette lighter fuse blows

The first thing you should check after the cigarette lighter fails is the fuses, there are two of them:

F6 for 15A, responsible for the portable lamp socket and cigarette lighter.
F18 at 25A is responsible for the heating and ventilation control unit, as well as the barchak lighting lamp, which according to the circuit is connected through the cigarette lighter.

Checking the cigarette lighter wiring

It is necessary to check the integrity of the cigarette lighter wiring. First of all, pay attention to the connectors located near the passenger’s left leg; they should be inserted tightly. Then make sure that the connector on the cigarette lighter itself is not disconnected.

Also make sure that the mounting block is in good condition. Based on the results of the check, the wiring to the cigarette lighter can be connected from Ш5-3 mounting block to the +12V connector of the cigarette lighter.

If the wiring is intact, and the fault lies in the cigarette lighter itself (for example, it shorts out), then only replacing it with a new one will help.

Finishing touch

The standard warm-up period is 20 seconds. Well, or 15-25 seconds (no more). Therefore, before assembly, adjustments are made:

Temporarily connect the battery;
Power is supplied to the cigarette lighter socket. Install the moving part.
Warming up occurs at a constant speed, but the “automatic” mode can be configured in different ways. To change the response threshold, squeeze or bend the two tabs on the body. Take the test.
