Why is the exclamation mark on the instrument panel of the VAZ-2112, what should I do?

A red exclamation mark that lights up in the lower instrument panel indicates a problem with the brake system. To be more precise, about the low level of brake fluid in the system. And this is understandable. Driving with faulty brakes is extremely dangerous. Not every driver, especially a beginner, knows how to brake with the clutch pedal. And this method of braking is not desirable, since it literally burns the disks of this unit. The brakes should be constantly monitored. A self-respecting driver will never start the engine without making sure the brakes are working properly. If an exclamation mark is lit on the instrument panel of a VAZ 2114, this is a serious warning - it is unsafe to drive this car. Below you will find out what the exclamation mark on the VAZ 2114 means and what problems this icon on the dashboard warns about.

External signs of a problem

Key symptoms that indicate the presence of such a problem include:

1. Sudden increase in fuel consumption.
2. Another reason is misfire.
3. The car engine is running too unstable. Instability can be expressed in anything. For example, this could be extraneous sounds or reduced power of the power unit. All this indicates the presence of some serious problems that require immediate solutions.
4. An obvious symptom that almost all drivers will notice is slower acceleration even when the throttle is fully pressed. If this happens constantly, then repairs should be started as soon as possible.

Description of faults

Tidy 2115 stopped working

Occurs after power surges or moisture getting under the panel (condensation). If the device has completely failed, but other elements of the car are working, check the fuse and wiring of the element.

When only part of the panel does not show or the board lighting has failed, perform diagnostics of the illuminators and their contact groups.

Tidy does not light up

If the backlight does not function, as well as the dimensions on the left side of the car, check the corresponding fuse. When the insert is working properly, you will need to diagnose the mounting block for voltage.

Panel 2115 blinks

It happens when the device does not work correctly. The backlight blinks and the elements constantly jump. There are problems with contacts here. The pads may become loose or oxidized.

The solution to the problem is to clean the contacts from oxidation and tighten/replace the pads.

The temperature sensor on the device 2115 does not work

The solution lies in diagnosing the system and correcting breakdowns.

The arrows on the dashboard 2115 do not work

The fault lies with the blown fuse F3. Before replacing it, be sure to diagnose the wiring and eliminate problems and possible short circuits.

Purpose of VAZ 2114 devices and interpretation of the symbols on them

Located on the left side of the dashboard, directly in front of the driver's seat, the VAZ 2114 instrument cluster plays an important role in driving. It contains pointer instruments, VAZ 2114 indicators with electronic digital windows and signal lights for various purposes.

• An induction speedometer, which receives speed readings from a sensor located directly in the gearbox, shows the actual speed of the car from zero to two hundred kilometers per hour. The division price is 10 km/h. It must be borne in mind that such devices have a permissible error of at least 5 km/h. In the lower, central part of the device there is a window with an electronic display, in which two lines reflect the total mileage for the entire period of operation of the car and the current mileage.
• To the left of the speedometer is the tachometer. This is an electronic device that, receiving a signal from the on-board computer, shows the current crankshaft speed at that particular moment. The scale has divisions of 5 units, digitization is done after 10 units, the maximum value is 80. When multiplied by 100, the real number of revolutions is obtained, for example, 30 multiplied by 100, the result is 3000 rpm. The range of 55 - 60 is shaded in red - this signals that the critical speed is approaching. The critical range of 60 - 80 is shaded in red. If the speed increases to these values, the engine may fail. In the lower middle part of the device, an electronic display displays the time and the actual ambient temperature.
• To the left of the tachometer there is a dial gauge for the coolant temperature. It receives a signal about the actual state from the coolant temperature sensor, which is located between the cylinder head and the thermostat. The division value is 20 degrees. Digitization of the device begins at 50, after two divisions it is 90 and the divisions end at 130 degrees. The red, danger zone starts at 105 degrees. If the arrow falls into this zone, then the engine must be turned off immediately, no matter what mode it is operating in. Due to overheating of the engine, failure of the main blocks of the power unit is possible. At the top, near the number 130, there is a graphic temperature icon. To the right of the speedometer is a device indicating the presence and level of fuel in the car’s fuel tank.

The numbers on the scale indicate:

1. 0 is an empty tank.
2. ½ - half a tank.
3. 1 is a full tank.

The graphic symbol of a gas station at the top of the device indicates a fully filled tank. At the bottom right, an indicator in the form of a gas pump lights up in orange, indicating that the remainder in the tank is less than six liters.

Improving the climate on the road and other details about the sign

An exclamation mark came on on the Priora's instrument panel

Without exception, all motorists on the highway are obliged to ensure traffic safety for both themselves and others. And an exclamation symbol on the rear window of a car helps to reduce difficult situations on the highway, which increases the confidence of inexperienced car drivers, as well as their ability to take adequate actions.

Most car owners show increased attention to cars with the “newbie” attribute, try to leave more space for maneuvers, do not honk when slow, etc.

And these are the right actions on the part of professionals towards inexperienced drivers.

Required for maintenance

If you are a novice driver, but have not put up a sign, no one will fine you for it. But you won’t pass the technical inspection without it. Since the absence of a “yellow mark” is a failure to comply with the requirements under which the vehicle can be allowed to operate.

A novice driver cannot pass a technical inspection without the appropriate sign.

Place for a sign

So, where to put the novice driver sign? The traffic rules indicate that the sign must be attached to the back of the car, but in what exact place is silent about this. But without exception, all car instructors recommend the rear window as an installation site. Namely its upper corners. Right or left, it doesn't really matter. The main thing is that the square in these places is best seen by those driving behind.

How are the neighbors doing?

A typical attitude towards newcomers to driving exists in many countries. Also, in most states, installation of the novice driver sign is mandatory, and considerable fines are imposed for violation (lack of a “novice” sign).

For the Czechs, a newcomer is symbolized by a drawing of a hat, pasted on the car. Lithuania - the attributes are made on white in the shape of a maple leaf.

Different countries have their own signs warning that a novice is driving.

In the United States, the upper left corner of the state. numbers, place for red symbolism of inexperience. And Italy is a black “P” on a white square background; here, for the first three years, an inexperienced car owner cannot drive at a speed of more than 100 km/h on the highway, and within the city limits, no more than 90 km/h.

As it was before with us

Back in Soviet times, an applicant for a license to drive a vehicle was given a temporary license for two years after passing exams. And he could drive at a speed of no more than 70 km/h.

After two years, if there were no violations, the car owner received a permanent document. Well, if an offense was still present, the careless motorist was subjected to a full retake procedure.

In the USSR, a driver received a permanent license only after 2 years of driving without violations

Unstable operation in cold conditions

From time to time, drivers encounter a problem: the VAZ 2114 engine stalls during a cold start, but as it warms up, the operation evens out. In this case, the reasons may be:

• large valve clearance;
• low compression, wear of compression rings;
• the mass air flow sensor is faulty;
• air leakage under the intake manifold gasket;
• poor quality fuel;

When the car shows signs of shaking, you should contact a service center for diagnostics. Diagnostics are carried out using special equipment, where a specialist can accurately determine the cause of the malfunction. Of course, if you have enough experience, you can figure out the reasons for the unstable operation of the engine yourself.

Error codes VAZ 2115

The VAZ company develops on-board computers so that fault codes for Lada 2115 and other models can be read in two ways at once.

The self-diagnosis procedure involves collecting and decoding errors through the on-board display. This method is suitable for quick repairs and troubleshooting.

From 2005 to 2022, more accurate diagnostics became possible. A specially designed OBD2 port allows you to connect equipment to the car. An external computer shows problems down to every detail.

How to remove the instrument panel from a VAZ-2114

Before you finally remove the dashboard on the VAZ-2114, you need to understand the specific components that will have to be dismantled:

• a key component on which the BC is attached, a block of various devices, as well as all kinds of keys, switches and other components;
• a trim that is installed on the VAZ-2114 mainly for beauty, but also has air duct outlets;
• plugs;
• brackets;
• ashtray body;
• crossbars;
• shield;
• central bracket;
• console screens.

Tools and materials

To remove all the necessary elements, it is not at all necessary to have any expensive tools or special equipment. It is enough that the garage has a standard set of screwdrivers, as well as instructions for working with the VAZ-2114.

Sequence of operations when removing a torpedo from a VAZ-2114

In order to remove the instrument panel from a VAZ-2114, it is enough to do everything in accordance with the simple instructions given below:

1. Using a Phillips screwdriver, remove the 3 screws securing the left console screen to the dashboard. It is recommended to get a short tool, as it is much more convenient.
2. Carefully remove the lower part of the trim from the body bracket, removing the screen.
3. Remove all screws securing the console screen to the panel. At the same time, do not forget to constantly belay the pad with your hand.
4. Remove the screen. At the same time, be sure to ensure that it does not cling to any kind of cords.
5. Disconnect the connectors to disconnect ground from the battery. If a radio is used in transport, then in this case it should also be separated from the main wires by removing the connecting block. If it is not in the car, it will be enough to remove the wires from the dashboard, making sure that they have a plug. Be sure to turn off the cigarette lighter and also remove the socket with the light bulb that illuminates the ashtray.
6. Remove the handles from all levers that control the heating dampers. It is recommended to pry them off with a flathead screwdriver to make the procedure easier. There is a special protrusion on the lever, and when the handle is installed, it is combined with the lever through a special hole. That is why, when removing it, you should use a thin screwdriver to pick it up and lift it, freeing it from this protrusion.
7. Remove the electric fan toggle switch (you just need to pull it out of the connector).
8. Unscrew all the screws securing the VAZ-2114 dashboard to the brackets on both sides.
9. Release the shield and trim by removing two self-tapping screws located in the window near the instrument unit;
10. Take out the plug and remove the screw located behind it.
11. Remove the two screws that hold the trim in place at the bottom, then pull it out.
12. Label the wires to identify which switches they go to, then unplug them.
13. Remove all bolts from the steering bracket.
14. Unscrew the screws holding the lower bracket mount.
15. Remove the light guide.
16. Remove the element securing the heating control unit, and then remove the cartridges that are located behind it.
17. Remove the decorative insert, removing any external components.
18. Remove the hydraulic corrector lighting.
19. Loosen all the fasteners of the panel, then remove the bolt with which it is secured to the crossbar, located on the left side.
20. It remains to remove the VAZ-2114 torpedo.

You can clearly see how to remove the instrument panel of a VAZ-2114 in the video:

How to remove the tidy

To dismantle the panel you will need to perform a sequence of actions.

1. Disconnect the machine and place it in a stable position.
2. Lower the steering wheel completely to the lowest position.
3. Remove the plastic column casing by unscrewing the fastening screws.
4. Next, you need to use special spatulas or a flat-head screwdriver. You will need to snap out the plastic clips securing the instrument panel trim.
5. After removing all the facings, you should unscrew the 4 screws that secure the shield itself.
6. After this, you will need to lift the board and turn off the contact groups of the devices.
7. Now you can completely remove the shield from the car.

Main elements of the VAZ 2114 panel

To better understand the operating principle of the VAZ 2114, you should understand the instrument panel. It is a key source of information about the car. Thanks to it, the car enthusiast will be able to obtain any information about the functioning of all components of the car and its technical condition. The instrument panel also reflects the operation of sensors and all other elements.

Location

The instrument panel of the VAZ 2114 is located in such a way that the driver can see all the icons, as well as the lights. To use the panel as efficiently as possible, you should study it, as well as the location of all indicators and buttons.

Dashboard VAZ 2114

The key elements on the dashboard are:

1. Speedometer. It allows you to know about the current speed. The sensor that records the speed is located directly in the gearbox. The speedometer error is 5 km/h.
2. Tachometer. The main function of this device is to transmit speed readings in real time. The tachometer receives information from the on-board computer.
3. Coolant temperature indicator. Coolant is a cooling liquid. If the temperature becomes too high, you must stop driving and then turn off the engine. It needs to cool down, otherwise the power unit will require expensive repairs.
4. A display with information about the level of fuel filled in the gas tank. If the driver sees the number 0, this means that the tank is empty. If it is 1, it means that the tank is filled to capacity with fuel.

At the very top there is a gas station symbol. The purpose of this icon is to warn the driver that the tank is full. If the orange icon lights up in the lower corner (right), then there are less than 6 liters of fuel in the tank.

The “canister with a drop” icon indicates that the oil level has dropped.

“Windshield wipers and fountain” - not enough washer fluid.

“Thermometer” - low coolant.

“Car with open doors” - some door is open.

“Sign with a crossed out light bulb”—problems with the brake lights.

“Circle and lines on the side” - wear of the pads.

"Check Engine" engine problems.

Letter P - handbrake is off.

How to check the brake fluid sensor

In order to check its serviceability, it is necessary, with the engine running, remove it from the tank body and manually change the position of the float. If the indication on the instrument panel does not disappear and does not react in any way depending on the influence on it, then the sensor is faulty and needs to be replaced. However, if the sensor is working properly, there may be a brake fluid leak.

What to do if the exclamation mark on the VAZ 2114 lights up

If an exclamation mark lights up during braking, this means that the brake fluid level has dropped below the permissible minimum. In order to solve the problem, you should top it up. Therefore, if an exclamation mark is lit on the panel of a VAZ 2114, there is no need to panic. The problem can be solved by adding a small amount of brake fluid to the expansion tank.

Typically, a leak can occur around the rear bumper. The thing is that this area heats up very quickly. Excessive overheating often causes problems that are associated with a lack of brake fluid. In order to notice a leak, you need to inspect the damage site as carefully as possible.

If the leak occurs in the area where the caliper is located, then the situation becomes much simpler, because you can find the leak right on the caliper. If a leak occurs on the rear cylinder, its traces will be visible on the drum. Moreover, liquid from the drum can flow in a stream or simply drip.

The traditional time for problems with the listed elements to arise is the cold season. In Russia, from December to February, similar problems are often observed on models from other manufacturers, so there is nothing to worry about. You can fix the problem yourself.

Hi all! Today I want to raise a rather current topic that, judging by the questions on the forums and the number of requests in search engines, worries a large number of people. I want to talk about a phenomenon where when you press the brake pedal, an exclamation mark on the dashboard lights up.

I will try to give a comprehensive answer to this question and explain why this happens and what kind of damage may be involved. Go!

Let me start, perhaps, with the fact that if a lamp (!) lights up on the panel, it means something is wrong with the brake system. As a rule, this indicator signals a low level of brake fluid (BF) in the system. As you can imagine, faulty brakes are no joke and the problem needs to be addressed. I’ll say more, if anyone doesn’t know, OPERATING A CAR WITH A BURNING INDICATOR (!) IS PROHIBITED! Since you don’t know what’s wrong and what caused this error to appear on the dashboard.

The level of brake fluid in the expansion tank has decreased

One of the main reasons why an exclamation mark lit up on the dashboard of the VAZ 2114 is that the amount of brake fluid in the expansion tank has decreased. It is with this problem that you absolutely cannot leave the garage. The hydraulic fluid level is checked using the marks shown on the reservoir, which is located on the driver's side under the hood.

The red line shows the optimal amount of brake fluid.

Please note that the VAZ 2114 uses brake fluid marked DOT-4. At the same time, it is important to know that you cannot mix brake fluids of different brands or different manufacturers, even if the manufacturer tries to assure you otherwise. Sometimes additives, components of liquids that manufacturers add to improve performance, enter into a chemical reaction, and the liquid loses some of its properties. Try to use the same type and brand of brake fluid.

DTUZh is out of order

We looked at the fluid level in the reservoir, made sure that neither the reservoir nor the hoses were leaking, and there were no puddles of brake fluid under the car. We suspect a malfunction of the brake fluid level sensor (BLLS). This sensor is located in the reservoir of the master cylinder (GTC). To check it, you need to turn on the ignition and make sure that the lamp lights up. Then we disconnect the connector from the sensor to de-energize it. If the exclamation mark goes out, then the problem is most likely in the sensor, or more precisely, in the float, which sinks to the bottom when there is a normal amount of liquid in the container.

In this case, if the control device is working, the exclamation mark should light up. Conversely, if the sensor is not working, the warning signal will not light.

The DTU cannot be repaired. If it is not working, you will have to buy a new one and install it. The price of the part is 150-250 rubles.

After making sure that the sensor is in order, you should check the electrical wiring. That could be the problem too. The wiring is checked as follows: first, the DTSZ is disconnected from the power supply, then they take a copper wire and connect it (close) the sensor power contacts on the wiring, and not in the sensor itself. If the exclamation mark lights up, the problem lies in the wiring. Arm yourself with a multimeter and ring the wires, check the contacts. Or contact an electrician for help.

What to do if the lamp comes on?

1. The first thing you need to do is check the fuel fluid level. This is done simply and without any difficulties. Open the hood and look at the level, it should be between o and “MAX”. The level must be monitored constantly; for those who forget to do this, there is an exclamation mark. It lights up based on a signal from the sensor, which signals when the fuel level is below the permissible level.

By the way! There are often cases when the light comes on when driving over uneven surfaces and goes out as soon as the car drives onto a more or less level road. This happens precisely for the reason that the level of “brake fluid” is close to o and when the car is rocking, the sensor detects a low level and signals this to the instrument panel.

1. If everything is in order with the brake fluid level, you need to check the fuel injection system, which is located in the brake fluid tank. I'll tell you how to do this now.

Brake pads worn out

We diagnosed the sensor and examined the wires. At first glance, everything is in order, and the red indicator is persistently glowing. The problem may lie in the brake pads. There is no pad sensor on the VAZ 2114, but when their wear reaches a critical degree, the pistons of the brake cylinders move forward and the free space is filled with hydraulic fluid. At the same time, the pitch of the brake piston increases, and it causes the indicator light on the tidy to light up. If you know that the brakes have been working for a long time, you haven’t climbed under the car for “a hundred years”, it’s still worth doing it and checking the condition of the brake pads. Most likely they will have to be replaced.

In general, brake pads are a short-lived item. During normal operation of the car, their mileage is:

• for front pads - 15-20 thousand km,
• for the rear ones - 50-60 thousand km.

True, these numbers are very arbitrary. Everything will depend on your driving style. In reckless drivers, they are reduced by one and a half to two times. And although the light comes on infrequently due to the pads, the driver/car owner should be more attentive to these parts of the brake system.

Beginner driver sign

Details Category: Articles Published 03/31/2015
Today we’ll talk about the “Beginner Driver” sign: who it is intended for, whether or not you should stick it on your car, what punishment is provided for its absence, and we’ll also tell you about the results of our small experiment.

Let us remind you that the “Beginner Driver” sign first appeared in Russia at the official level on March 1, 2009.

Who needs a Novice Driver badge?

According to paragraph No. 8 of the “Basic provisions for the approval of vehicles for operation,” the “Beginner Driver” sign must be installed on vehicles driven by a driver with less than 2 years of driving experience.

Exceptions include tractors, motorcycles and self-propelled vehicles; they do not require a “Beginner Driver” sign.

Requirements for the “Beginner Driver” sign

According to the requirements, the “Beginner Driver” sign must be a square with a side of 150 mm, with an exclamation mark 110 mm high. Most often, signs on sale are on self-adhesive film, intended for installation on the outside of the car. The sign must be installed at the rear of the vehicle. It is up to the driver to decide which side to place the sign on – right or left. It is advisable that it does not limit the view.

Fine for not having a “Beginner Driver” sign

There is no fine in the Code of Administrative Offenses of the Russian Federation for the absence of a “Beginner Driver” sign. The only thing that threatens a driver with less than 2 years of experience without such a sign is a refusal to receive a technical inspection ticket when undergoing this procedure. But, of course, this does not scare anyone - nothing prevents you from sticking a sign before entering the SGTO and peeling it off immediately after leaving.

Is it worth it or not to put up a “Beginner Driver” sign?

To answer this question, I decided to conduct a small experiment - stick a “Beginner Driver” sign on my car and drive with it for a week along the streets of Naberezhnye Chelny. The purpose of this experiment was to understand whether the attitude of other drivers towards you changes if you have such a sign.

It’s no secret that many new drivers are afraid or embarrassed to put the “Beginner Driver” sign on their car. They believe that other drivers will deliberately harass or rush them on the road.

Having stuck the sign on my car, I was, in principle, prepared for such a reaction from the surrounding drivers.

However, in reality everything turned out better than I expected. I have never noticed that someone deliberately cut me off or tried to somehow interfere with me on the road after seeing a sign pasted on a car. Moreover, several times I deliberately drove off very slowly at a green traffic light, but the drivers of the cars behind me did not even honk at me.

The only thing that changed after this sign appeared on the car is that other drivers began to keep a greater distance from me and drive around my car further away. I think that this is even a plus for a novice driver.

For example, a situation where you are standing at a U-turn, giving way to the flow of cars. A car stops behind and waits. You can see his impatient expression in the rearview mirrors. A few seconds later, he passes my car on the right, demonstrating his “highest” level of driving skills, and spins away. Like, why stand here waiting for this “teapot”. And this is not an isolated case. At the same time, when there is no sign, such drivers begin to blink their high beams and honk nervously.

Thus, I consider the presence of a “Beginner Driver” sign to be more of a plus than a minus for a new driver. Undoubtedly, there are drivers who infringe on drivers with an exclamation point on the window, but, fortunately, there are not many of them. Most drivers will simply avoid meeting you on the road if you have such a sign.

Moreover, among my friends there are many people who have been driving for more than two years, but they have not driven for a long time. Having bought a car, for the first few months (and some even six months) they drove with the “Beginner Driver” sign until they learned to confidently drive their iron horse. Therefore, even if your experience is more than 2 years, but you do not feel confident enough behind the wheel, do not hesitate to stick this sign.

ABS turns on randomly, the light blinks or lights up periodically

One of the most difficult forms of breakdowns is the constant blinking of the ABS light. This means that the anti-lock braking system sensors send incorrect signals to the computer, which, in turn, issues other incorrect commands to the vehicle's systems and modules. In such cases, many people prefer to simply turn off the anti-lock system, since unpleasant incidents may occur. For example, turning on ABS at a speed of 90 kilometers per hour with light braking can damage the chassis of the car and contribute to a complete loss of control over control. It's better to do this:

• bring the car to a service center for diagnostics, find out the reason for the chaotic operation of the equipment;
• for domestic cars equipped with a primitive anti-blocking device, it is better to immediately disable the system;
• complex designs and on-board electronic systems of foreign cars will have to be reflashed for repair;
• on some machines it will be easier to find the problem and fix it than to disable the anti-lock;
• you need to keep in mind that this particular system is not always the cause of the ABS light coming on; the problems can be different;
• During the diagnostic process, it is better to check the entire on-board electrical system and equipment.

By paying a certain amount for a car inspection, you can get the right answers to important questions. Sometimes a light that comes on on the panel can develop into a full-fledged repair of important units and components of the car, so you will have to spend a lot. But in most cases, this problem is not so expensive to solve. The cost of repair work depends, of course, on the make and model of the car, and on the price of spare parts. If an ABS sensor for a domestic car costs from 600 rubles, then a Japanese SUV will cost more than 10,000 rubles to replace one such sensor. We suggest watching a video about solving a similar problem using computer diagnostics:

VAZ 2114: I turn the keys, it won’t start

Hello everyone, please tell me I arrived, turned off the car, then immediately wanted to start it, but it wouldn’t start! This is the case: on the panel, everything lights up normally, nothing closes anything, you start to start, you hear one click and the starter still doesn’t turn, I knocked on the retractor, the car started up after a few starts, it didn’t start again, I knocked and started again, what could be the problem? Can anyone tell me? Video sponsor: ... - “Enthuziast-Auto” car service in the Eastern Administrative District of Moscow. All types of work!

REASONS FOR UNSTABLE OPERATION OF MOTOR 2114

Let's consider several standard situations that can happen with an 8-valve 4-cylinder engine.

UNSTABLE OPERATION ON A COLD ICE

It often happens that a VAZ 2114 stalls when cold, but as it warms up the engine levels out and starts working stably. There could be several reasons:

1. The ECU sets the fuel mixture too rich to cold;
2. The spark plug does not work, but when heated, the spark plug still “breaks through”;
3. The high-voltage wires are damp or moisture has entered the ignition coil;
4. Parts of the piston group are worn out.

UNSTABLE OPERATION OF A HEATED ENGINE

It also happens the other way around - a cold internal combustion engine operates more or less steadily, but as it warms up it begins to throttle. Usually the engine starts when hot because:

• The cylinder head gasket has burned out;
• The ignition coil breaks;
• The engine control unit is faulty.

THE MOTOR STARTS AT IDLE SPEED

Most often, a situation arises when the engine stalls at idle speed. Moreover, it makes no difference whether this happens when it’s cold or when it’s hot. There can be many reasons for this, ranging from a simple spark plug failure to malfunctions in the piston group of the internal combustion engine. While it is very easy to replace a spark plug, wear on the cylinders in the block can lead to a major overhaul.

Most often, the engine does not operate stably at idle in the following cases:

• The valves are not adjusted (clamped);
• The timing belt is installed incorrectly (the marks do not match);
• The IAC is faulty;
• The cylinder head valves are bent or burnt out (the valves can bend during a water hammer when a large amount of water gets into the air filter housing);
• The piston burned out;
• There is a malfunction in the electronic engine control system. The sensors, the ECU itself, electrical wiring and I/O wires may be to blame here.

There are many options for why the car idles at idle, but there are still the most basic ways to determine faults.

The red exclamation mark on the dashboard lights up when accelerating

The clutch is stuck, but what makes it do this? Bent fork? Perhaps you need to open it up and take a look. Manually push all the gears onto the opened box. It is possible that the intermediate shaft or the primary shaft is jammed. On the opened box, twirl them with your hands. What about the aiming that doesn't lead? Further. The second one doesn't turn off. this is closer to solving the problem. Either the plungers jam in the cover with the forks, or the synchronizer nuts begin to jam due to large backlashes in the secondary shaft. Which again only an autopsy will prove. We have to wait for the autopsy results. A hissing noise after you press the brake pedal a little. indicates that the VUT is not tight. This is 100% The light comes on when braking. Here either the brake fluid level indicator is stuck, or there is an indicator of a malfunction in the brake system. The level indicator can be checked easily. We remove the plug from it and go for a ride; if the light doesn’t light up, that means it’s the problem. If the light comes on, we return the plug back and go into the brake malfunction indicator and turn it off. We are waiting for the results.

Tires

First of all, pay attention to the compliance of the brand of the selected tire with the weather conditions. Do not console yourself with the thought that all-season tires will allow you to fully move in winter - this has long been a refuted belief.

Remember that traction on the road surface depends on tires, and therefore braking distance and handling.

Pay special attention to the age and tread depth of your tires. The value of the latter should not be less than 1 mm, since otherwise there is a high risk of aquaplaning or skidding even in light rain due to impaired drainage in the tread

The presence of so-called “bumps” - local swellings indicating that the tire may burst at any moment, cracks characterizing the age of the rubber itself, as well as the presence of protruding steel threads - cords - is unacceptable. All these indicators clearly indicate the need to quickly replace the entire set of tires, since installing tires with varying degrees of wear, especially on one axle, is unacceptable.

As a rule, there are special indicators on tires, by which you can estimate the percentage of their wear; it is made in the form of several colored stripes on the working surface, the gradual abrasion of which allows you to plan timely replacement.

Thus, by following these simple recommendations, you will not only ensure the safe operation of your car, but also prevent possible expensive repairs.

Does the injector 1.5 VAZ 2108 - 2115 and Kalina not start?

Yesterday afternoon I started the car from autostart, the key fob seemed to beep that it had started. As soon as I left the entrance, the key fob beeped that it had stalled. I came, opened the doors through the alarm, sat down (it also seemed to me that there was some strange, non-standard smell in the car), turned the key one turn, waited, turned it all the way, but it didn’t start. It lights up the moment you try to start the car, and when you turn in the opposite position it just goes out. Look, maybe it will help someone.

Why is the exclamation mark on the instrument panel of the VAZ-2112, what should I do?
