What does the exclamation mark on the dashboard mean?

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.

Lada Granta instrument panel does not light up

When you turn the key in the ignition switch of a Lada Granta passenger car to the “ignition on” position, the composition of devices should begin to work. If this does not happen, then the driver will have to check the fifteen-amp fuse F20. You can find it in the mounting block located in the front panel to the left of the control column. The color of this fuse is blue, and it is the seventh in a row, if you count from below.

This fuse blows mainly because it protects not only the electronic circuit of the device composition, but also the cigarette lighter circuit, and drivers try to use this socket as a socket, connecting additional equipment through it (navigator, compressor, charger, etc.) etc.). The short circuit occurs due to the fact that the plugs of these devices are unbent by two U-shaped symmetrical contacts located at the base, which begin to touch the body of the socket connected to the ground of the car. Before installing a new fuse, you need to bend these contacts back to the center, but this should not be done with an iron object.

If, after checking fuse F20, it turns out that it is intact, then to determine the circumstances of the failure of the device composition, you will have to carry out a test, which consists of pressing the odometer daily mileage reset button with the ignition off and then turning the ignition on again. If, while holding this button, you see that all the device arrows start moving from zero marks on the scale, and then go back and this process is repeated three times, then you can come to the conclusion that the composition of the devices itself is working properly.

Taking into account the fact that all information (vehicle speed, crankshaft speed, cooling water temperature, fuel level in the gas tank) comes to the dashboard from the electrical control unit (ECU), we can come to the conclusion that for some reason the ECU does not output for communication with the composition of devices. One of the circumstances of this state of affairs may be the ingress of water or antifreeze (if the interior heater radiator is not tight) inside the ECU housing. This can cause corrosion of the track on the ECU printed circuit board going to the CAN bus, which will lead to loss of communication with the composition of devices, because it is through the CAN bus that information is transmitted from the electrical control unit to the devices.

Many owners of a Lada Granta car (Lada Granta) have encountered such a malfunction as an extinguished dashboard . Typically, this malfunction occurs after trying to turn on a recorder or a compressor to inflate tires in the car’s cigarette lighter. When you turn the key in the ignition, the dashboard does not turn on, the greenish on-board screen does not glow, the car signal does not work, the trunk does not open with the button - all these are signs of a blown fuse F20 located in the mounting block in the front panel to the left of the control column. Fuse F20 is the seventh from the bottom and has a blue body and is designed for a protection current of fifteen amperes. This fuse mainly blows when you try to use the cigarette lighter as a socket to connect additional devices: navigators, recorders, charging a mobile phone, compressor, etc. A short circuit in the cigarette lighter occurs due to the rigid plug of electrical appliances, which, with its central contact, unbends two “U” shaped contact tabs “” at the base of the cigarette lighter socket. The main reason for the short circuit is the ancient, long design of the plug for connected electrical appliances, which is not designed for the new cigarette lighter installed on Lada Granta and Kalina cars. Before replacing the fuse with a new one, you must NOT use an iron object to bend these contacts to the center.

The cigarette lighter socket has a shallow depth, so it is difficult for the plug to stay in it.

To prevent small short circuits in the future, it is recommended to install an additional connector with USB outputs in the car for connecting navigators, recorders, radar sensors, etc. To connect a car compressor, it is not recommended to use the car's cigarette lighter as a socket. The most common way to connect a compressor is to solder two alligators instead of a compressor plug and connect the compressor directly to the car’s battery. If possible, change the compressor connection wire to a longer one 1-1.5 meters with a cross-section of 2.5 mm, so that you can reach the rear wheels without any problems.

After replacing the fuse, you can diagnose the operation of the dashboard. To do this, you need to press the daily mileage reset button on the Lada Granta dashboard and turn on the car’s ignition. The arrows of a working instrument panel will move and deviate three times to maximum values ​​and return to their original position.

Installing an additional USB connector for connecting electrical appliances

Since Grants do not have a uniform fuse connection diagram, on some cars the cause of a dimmed dashboard, a non-working power window on the right side where the passenger usually sits, a non-lit license plate light and the left rear parking light may be a blown 5A fuse F10.

If the instrument panel still does not work, check the F10 five amp fuse. Check if the side lights on the right side of the car are on. Sometimes the cause of a blown fuse and a dim dashboard is a burned out parking light bulb.

Common causes of fuse failures

• Natural factor - due to long-term operation of the technical device;
• Mechanical damage, accident, impact, collision;
• Short circuit in the circuit;
• Damage to insulation, oxidation of terminals, loosening of contacts;
• Water entering the mounting block, condensation formation, deformation due to high operating temperature.

Auto test of the VAZ dashboard. Standard on-board computer Lada Granta/Kalina 2

The liquid crystal display is an electronic device that displays trip information collected and processed by the trip computer. Depending on the configuration, three types of trip computers are installed on the car, differing in the amount of information displayed.

The display shows the following information:

• line one displays the current time or (in a variant) the gear shift prompt indication mode, as well as the automatic transmission operation indication mode;
• line two displays your choice of total or daily mileage;
• line three displays the outside temperature or (optionally) the functions of the on-board computer;
• line four displays the fuel level.

Principle of operation

Manufacturers have equipped the car model in question with an electronic speedometer. Such a system calculates speed as accurately as possible with a minimum percentage of errors. The system consists of the following elements:

So, next we’ll look at how the whole system works. Its main element is the speed sensor or EMF. The device operates on the principle of a Hall ignition and distribution system. The EMF is installed on the gearbox near the flywheel. The flywheel has a special risk. When this risk passes by the EMF, the contact inside the sensor opens. This creates an electrical impulse. As the speed of the vehicle increases, the number of such “openings” increases, which means more pulse discharges are created.

The pulses are sent through the wire to the computer, where the number of signals per unit of time is automatically calculated. Secondary confirmation comes in the form of pulses from the crankshaft position sensor. The on-board computer transmits the received data to the receiver - the speedometer drive. Depending on the magnitude of the received signals, the drive deflects the instrument needle by a certain degree.

The system is very reliable; it allows the on-board computer, based on the data received, to distribute the amount of combustible mixture into the engine, regulate the mixture of gasoline and air, maintaining optimal engine speed. Next, the symptoms of damage to the electronic speedometer of a Lada Granta will be described.

What to do if the battery light is on - car diagnostics

Diagnostic systems in modern cars allow car owners to practically not worry about the quality of operation of the equipment. If certain problems occur, the corresponding lights on the dashboard light up. After such an incident, you need to immediately diagnose the machine, find out the reasons for the breakdown signal and fix the problem. There are quite a few diagnostic lamps today, and by the combinations of their illumination, you can determine which components should be checked in the event of a potential breakdown. If while driving or with the engine running, certain lights on the instrument panel in your car continue to light up

, you should check the corresponding nodes.

Immediately when the ignition is turned on, the instrument panel will turn on completely, all light bulbs will be checked so that the driver can identify failed illumination elements. After a few seconds of loading the on-board computer, most of the lights fade out, only the oil and battery indicator lights up. When the engine is running, these two lights should go out. All that remains is the parking brake engaged indicator, if it is, of course, on.

How does ABS work?

The electronics regulate the brake force on all wheels, preventing them from locking when braking, but allowing the car to stop quickly. By braking sharply, the car will not lose stability.

If the system is out of order, or it is not installed on the car at all, then the wheels will lock during sudden braking. A strong skid may occur, especially in winter, or when turning. If the ABS is working properly, this will not happen. Even when turning, you can press the brake pedal sharply - there will be no skidding.

If the ABS light is on, the reason is a system malfunction. This is easy to check - accelerate to a speed of 40 km per hour and sharply press the brake pedal to the floor. If there is no pedal vibration and the wheels are skidding, then the ABS is not working.

If the system is working properly, you can sharply press the brakes and try to go around the obstacle. In this case, no skidding will occur. If the anti-lock braking system fails, the car will skid and hit this obstacle.

Fuses and relays in Lada Granta, electrical diagrams

If you bought a Granta and started having electrical problems, you may be faced with a manufacturing defect. But don’t be alarmed ahead of time, the first thing you need to do is check the fuses and relays in the Lada Granta and find out the cause of the malfunction. If you're lucky, you'll get away with simply replacing the fuse.

If not, you may have to go to a car service center or troubleshoot the electronics yourself. Remember - the main thing in such cases is to fully understand the problem, do not waste time on this, because any car owner should know as much as possible about his car (especially a domestic one).

Relay-breaker layout diagram

Fuse box

The fuse box in Grant is located to the left of the steering column, near the light switches. To remove the cover and access the fuses and relays, pull the top left side of the cover towards you. It’s made conveniently, everything is at hand and you don’t have to climb anywhere when getting up from the driver’s seat. Maybe this is a hint that they will often have to be changed, or maybe just convenience - the developers know better.

F1 (15 A) - engine control unit, injectors, ignition coil, cooling fan relay, short circuit 2x2.

If you have problems with electronics, and replacing this fuse does not help, in the worst case scenario, you will have to reflash the ECU or replace it. Also, if this fuse blows, the injectors and ignition coil stop working, which makes engine operation impossible. Therefore, if the Grant does not start, check this fuse first.

F2 (30 A) - electric windows.

If they do not work and replacing the fuse does not help, try unplugging it completely or removing the terminal from the battery for a couple of minutes, then connect it again. In this way, all temporary errors should be reset and if this is the case, the power windows will work again.

F3 (15 A) - alarm. If it doesn’t work, check this fuse, as well as the emergency light button, its contacts and the functionality of the lamps.

F4 (20 A) - windshield wiper, airbag. If the airbag warning light on the instrument panel comes on, check this fuse. The problem could be either in it, or in the electronic unit, or in the pillows themselves.

How to reset an error on Grant

There are three ways to get rid of the “Check Engine” icon:

1. Fix the problem;
2. Reset using OBD2 adapter;
3. Reset without adapter manually.

We use OBD2 adapter

Do you have a high-quality diagnostic adapter and the necessary software on hand? Then resetting will not be difficult. What to do if there is no program or diagnostic scanner?

The easiest way out is to buy a scanner from China. Price – 200-300 rubles. The main condition: read reviews about compatibility. Whether he reads your car or not is a lottery.

Once you have the scanner, insert it into the OBD connector to the left of the glove compartment.

The connector is located in an easily accessible location to the left of the glove compartment lid.

• Download Torque Lite program - free version, basic functions work;
• We start the car so that power goes to the adapter and error data appears;
• We turn on Bluetooth on the phone, add a new device (the adapter will be detected as OBDII);
• Open the Torque program - at the top of the screen there will be messages like Waiting for connection, Checking the CAN protocol, Connected successfully;
• Open the settings – Fault Codes – Show logged faults.

The saved codes will appear on the screen. There, using Clear logged faults, you can reset all errors and the “check” will go out. Not forever - until the problem appears again.

Open settings – Error codes – Show saved ones.

An option close to a scanner is installing an on-board computer . BC:

• Determines the error;
• Will show its code and decryption;
• It will help you reset.

How to remove a check without an adapter

Everything is simpler here. When you don’t have OBD or a phone with software at hand, you just need to disconnect the terminal from the battery.

which terminal to remove . De-energize the car for 5-7 minutes and all errors should disappear.

Lada Granta instrument panel lights do not light up

I am the owner of Lada Granta. I am writing about my car.

The fuse on the cigarette lighter burned out and the BC stopped working

There was a car service station nearby, so I decided to stop by. The auto electrician immediately, without even looking, said that the problem was in the fuse. He suggested setting it to 20. Two minutes and the problem was fixed.

The asking price is one hundred rubles (if I had known, I would have changed it myself).

Way out

1. Purchase and installation of a splitter and connecting all additional gadgets only through it. In this case, the cigarette lighter in your Grant will have to be used only for its intended purpose. And for the compressor, I bought myself a special adapter “Cigarette lighter socket with AIRLINE crocodile clips” to connect it directly to the battery.

Note. These antennae are made on the cigarette lighter to protect against overheating during operation, creating a short circuit and thereby preventing fire (burning wiring).

BC Multitronics UX-7 and error 0523

Hi all! At the beginning of January I bought a Multitronics UX-7 on-board computer from an official Lada dealer, and installed it from them. Price 1700 rubles.

Of course, there is nothing to install there; I plugged the dial insert into the empty socket, drag the other end of the cable through the panel and insert it into the diagnostic connector. But the fact that I installed and bought BC from them has already brought benefits. More on this later.

The BC shows all the main (and not only) readings of the engine and systems. It is very convenient to have engine temperature readings, gearbox temperature readings, engine speed readings, trip readings, system errors and much more at hand. I lowered the fan activation temperature, it was 101, and set it to 95. There are a lot of disputes on the forums because of this. But it’s better to turn on the fan one more time than to overheat the engine.

Relay block Lada Granta

The relays are located in the same fuse and relay box, which is located to the left of the steering column under the cover.

K1 - heater fan relay

K2 - power window relay. If they do not work, also check fuse F2; if this does not help, then the problem may be in the control unit.

K3 - starter relay. If it does not work (does not turn) and this relay is working, check the battery charge level. It could also be a problem with the retractor or the ignition switch and its contacts.

K4 - ignition switch terminal fifteen relay

K5 - turn signal and hazard warning relay. If the turn signals come on and do not turn off, this relay may be shorted. Also check fuse F3 (emergency mode).

K6 - windshield wiper relay. Check also fuse F4.

K7 - high beam relay. Also check fuses F14 and F15 and the lamps themselves.

K8 - horn relay. Also check fuse F20, signal switch contacts on the steering wheel.

K9 - low beam relay. Also check fuses F12 and F13 and the lamps themselves.

K10 - rear window heating relay. If the heating does not work, the problem may be in fuse F8.

Debriefing

1. The electronic control unit (ECU) for the electric power steering is fixed in the wrong place, under the heater radiator
   . Any leakage of this part causes the ECU to get wet, after which you will feel that the power steering is not working and the steering wheel has become heavy.
2. If while driving you notice that the tachometer or speedometer needle is at zero and does not move, rest assured that the ESD of your car is not working. This happens because these devices and (EUR) are activated from the same sensors.
3. Most often on Kalina, the speed sensor fails. Buying a new sensor and replacing it solves this problem. There are very often cases when replacing sensors does not help, (the electric power steering) still does not work. Begin to methodically probe the entire chain of wires related to the system (EUR).
4. Due to the constant vibration of the car and poor quality of production, connecting plugs and blocks independently break electrical circuits at the most inopportune moment.
5. Kalina's power steering behaves poorly when the on-board voltage drops
   . If an old generator produces less than 30 volts instead of 15 volts, then the electronic control unit of the power steering may also refuse to work.

If you broke down on the way

In recent years, the production of Lada Kalina cars (ECU) of domestic production was replaced with Korean ones. The kind they put on Hyundai cars. After that, power steering failures became significantly less frequent. But they started installing Korean blocks

. And how many thousands of Kalinas travel all over the roads, with old electronics?

Our advice to you is, at the first opportunity, change the electronic control unit on your car to a modern one, you will be healthier.

Electric power steering for modern cars has already become an integral part of them. On the Russian market it was first installed on the Lada Kalina ( VAZ 1118 ). The electric booster added both a lot of positive emotions and a lot of negative ones. Failure of this unit occurs quite often on the first samples. Our guest today was no exception – a car of the Lada “Kalina” family (Fig. 1).

The situation is quite typical: the client complains that sometimes the electric power steering turns off and the electric power steering warning light comes on, but after driving along some hole or rails, the electromechanical power steering (EMUR or EPS) resumes its operation.

This situation is very annoying, because not only the owner uses the car, but also his wife. It is much more problematic for a woman to turn the steering wheel without electric power assistance.

We start the car, and the electric power steering fault light actually lights up and it becomes quite difficult to turn the steering wheel. It is imperative to deal with this problem.

We connect the diagnostic scanner and connect to the EMUR control unit.

On the monitor screen we see the following error: C1044 – incorrect sequence of the rotor position sensor. What is a rotor position sensor and where is it located?

Let's take a break from our malfunction for a moment and touch on a little theory. Let's understand the EMUR device and what main parts it consists of. Let's consider all its parts separately.

Design EMUR Kalina 11186-3450008-00

1. Steering shaft
2. Electric motor
3. Electronic control unit
4. Torque sensor
5. Rotor position sensor

We remove the EMUR. On the nameplate (Fig. 7) there is article number 11186-3450008-00 manufactured by Aviaagregat, Makhachkala.

Remove the steering wheel, steering column switches and ignition switch. To get to the torque sensor , you must first remove the electric motor. We unscrew the bracket with 4 bolts, the cardan shaft, the lock nut and the 3 bolts securing the electric motor.

Power fuses

The power fuse box is located under the hood and is located between the battery, strut support and coolant reservoir. Looks like a vertically mounted box. By removing the top cover, access to the power fuses appears.

F1 (50 A) - electric power steering. If the steering wheel turns hard, also check fuse F32.

F2 (30 A) - heater fan

F3 (60 A) - generator. If the battery discharges quickly or the discharge lamp is on, check this fuse, as well as the operation of the generator itself and its brush.

F4 (60 A) - generator

F5 (30 A) - low beam headlights. Also check relay K9 and fuses F12, F13.

When troubleshooting any electrical problems, use caution. Replace fuses and relays only with the engine off and the ignition off.

If your fleet contains not only Grants, you can also read about Kalina fuses and relays.

I’ve already written more than once, the dashboard

, i.e. it sometimes lights up for a couple of seconds (once a month) and goes out, the problem has been around for a long time, I thought, I recently transferred it from another car, one of them doesn’t light up, I changed the fuse, I changed the cigarette lighter, I changed the relay, has anyone encountered this? It’s clear that it’s easier to go to an auto electrician))) But suddenly someone has already encountered this. Thank you))

Symptoms

Car components rarely fail unexpectedly. Breakdowns are often preceded by various symptoms. There are also such cases when the speedometer breaks down. These include:

Symptoms of unstable operation of the power unit can be directly attributed to a breakdown of the speed sensor. It is on the basis of its data that the ECU controls fuel consumption for engine idle speed, and also maintains the balance of the amount of mixture while driving at different speeds. The following will describe in detail why the speedometer on the Grant does not work and the reasons for each breakdown.

Possible faults

If everything is clear with the description, then let’s move on to the malfunctions. Like any other electronic unit, Granta instrument panel

is also susceptible to various malfunctions.

What kind of breakdowns can occur in the operation of the control panel:

• The tidy is broken. If the shield fails, there can be quite a lot of symptoms. For example, only some or all of the devices will refuse to work. If this is the case, then the problem in this case may lie either in the power supply of the device or in its board. It is better to entrust repair problems to specialists.
• The tidy is glitchy. For example, all doors are closed and the unlocked door indicator is on, or the optics are not turned on, but the corresponding light on the dashboard is flashing. As a rule, in this case the problem lies precisely in the board (of course, if the sensors are working). If the problem is in the board, then flashing the dashboard firmware can solve it, but this option does not always help. It is possible that the electrical equipment lights are on on the dashboard due to a faulty sensor, so it would be a good idea to check its functionality.
• All devices work, but there is no backlight. If all the backlight bulbs do not work at once, then most likely the problem lies in a blown fuse or a damaged wire or connector. Checking the wiring is done using a multimeter.
• Only part of the light bulbs or one of them does not work. In this case, the malfunction consists of a burnt-out lamp; to eliminate it, the instrument panel in the Lada Granta is dismantled, after which the burnt-out lamps in it are replaced.
• The equipment indicator on the dashboard does not turn on. For example, you turn on the high beams, but the corresponding light does not light up. This may be due either to a failure of the indicator itself (the lamp is changed in the same way), or to a breakdown of the sensor. It is quite possible that there is poor contact between the light bulb and the wiring.
• Speedometer failure. The cause of the malfunction may lie in the board or speed sensor installed on the device. The situation is similar with sensors - fuel level, engine temperature. If they do not work or show incorrect values, then the problem should be looked for in the controllers themselves, wiring or board. It is possible that the devices are not working simply due to poor contact.

Instrument cluster display does not show data periodically

Good afternoon Problem with the display on the Lada Granta instrument panel. Sometimes it stops displaying information about vehicle performance. The display itself is fine. It helps if you disconnect the battery terminal, or simply stop the power supply to the instrument panel (by removing fuse F34). The most interesting thing is that if you do nothing, then in a day or two, the display can start working on its own and start showing everything. Share your thoughts on where to start looking for a solution to the problem. Since this behavior in his work is a little confusing. Thank you in advance))

Description and location of indicators and instruments on the panel

First, let's look at the description; the Lada Granta instrument cluster, the diagram of which is shown above, includes the following components:

• Tachometer, this sensor allows you to find out what the crankshaft rotation speed is at the moment.
• Indicator of malfunctions in the operation of the internal combustion engine control system.
• Left turn signal.
• Engine fluid pressure sensor. If it lights up after starting the engine, you need to check the oil level in the unit; if it is too low, there may be a leakage problem.
• Anti-lock braking system indicator.
• Light bulb of the standard anti-theft system - immobilizer. This unit is designed to block the engine from starting in the event of unauthorized entry into the car.
• An indicator of antifreeze overheating in the cooling system appears if the engine temperature reaches one hundred and fifteen degrees.
• A light that turns on if the control unit has detected an emergency condition of the brake system. As a rule, its appearance is due to a lack of brake fluid in the reservoir.
• Right turn signal.
• Low battery indicator.
• Speedometer, the needle of which corresponds to the speed limit at which the car is moving. The speed sensor, which displays this information on a scale, is mounted on the gearbox housing.
• Indicator for turning on the exchange rate control system.
• Upshift prohibition lamp (as a rule, not used).
• This indicator appears when the high beams are activated.
• Symbol for turning on the rear fog lights.
• Lamp for low beam lighting.
• Front fog light activation indicator.
• A button designed to reset the daily mileage.
• LCD screen that displays data about the last trip, in particular, mileage. Depending on the vehicle configuration, the data displayed on the screen may differ. In general, the display can display time, mileage, outside air temperature, on-board computer options, fuel volume, as well as information in the form of hints regarding gear shifting.
• Indicator of unlocked doors in the car.
• Symbol of reserve fuel remaining in the tank.
• This indicator appears when the tire pressure is insufficient.
• Signal lamp for EUR operation. If it lights up when the engine is running, then most likely there are problems with the electric power steering system.
• This symbol illuminates when the seat belts are not fastened.
• Engine fault indicator, in most cases not used.
• Airbag status symbol. It always appears after turning on the ignition, since the system is in testing mode. If it continues to light
  after starting the power unit, this may indicate a problem with the system, so you need to contact service.
  If this indicator is on, then in the event of an accident the airbag either will not deploy, or it may deploy at the wrong moment while driving, which could be even worse (author - Lada Granta
  Fan channel).

General information

In all modern cars, including the Lada Granta, when the ignition is turned on, the engine warning light comes on, as well as sensors of other systems. If your vehicle is in perfect order, the Check Engine light will go out a few seconds after the engine starts. But, if the engine warning light remains on, you have a serious reason to seek help from a car mechanic.

The appearance of a Check Engine indicator on the instrument panel can say a lot. Next, we will try to analyze the main reasons why the engine warning light on the Lada Granta comes on and what the driver should do in this case!

The main reasons for the appearance of “Jackie Chan” (Check Engine)

The check engine light comes on when one or more vehicle systems are not working properly. In this case, the engine management system sounds an alarm and sends you a signal in the form of this icon.

In some cases, simply resetting the battery terminal helps. In this case, most likely low-quality gasoline was poured in and misfire occurred, or increased detonation, etc.

Low fuel quality

The quality of gasoline in the Russian Federation leaves much to be desired

Among the common reasons for the activation of the engine warning light is refueling the car with low-quality gasoline. In this case, you may need to drain the old gasoline.

Each engine is designed for a specific brand of fuel - A92, A95, etc., which have a certain octane number. If this indicator does not correspond to reality, that is, the octane number of the filled gasoline is below normal, a destructive phenomenon such as detonation may occur during engine operation. According to the requirements of the manufacturer, only 95 gasoline must be used in Lada Granta.

To prevent possible problems, the electronic engine control unit displays a “Check Engine” signal on the instrument panel. Those. in this case, the indication serves as a kind of insurance.

Also pay attention to how the car drives. On low-quality fuel, it will begin to suffocate, start to stall and stall at idle, fuel consumption should increase (read more about fuel consumption standards for the Lada Granta).

The solution to this problem is extremely simple - drain the low-quality gasoline and fill the car with another fuel. After the fuel pump starts pumping in new, higher quality gasoline, the Check Engine indicator will go out.

Problems with the fuel pump or fuel filters

The engine warning light may come on as a result of problems with the fuel pump.

Once again, the reason is indirectly related to gasoline. But, this time the engine warning light may come on as a result of problems with the fuel pump or clogged fuel filters. At the same time, in addition to the constant lighting of the engine indicator, starting the engine becomes more difficult. Finally, a clear sign will be “floating speed” and “dips” when pressing the accelerator pedal.

It is not difficult to make sure that the problem is related to the fuel pump - just check the fuel supply pressure. As a rule, a pressure of 3 atmospheres is considered normal. If the pressure is lower and the filter is clean, the fuel pump will need to be replaced.

If the fuel filter is clogged, replace it. Read more about replacing the fuel filter here.

Dirty fuel injectors

Clogged fuel injectors = improper mixture formation

The next problem is related to the injectors through which fuel is supplied to the engine cylinders. Considering the quality of domestic gasoline, it is not surprising that injectors quickly become clogged with various elements contained in gasoline. As a result, improper mixture formation occurs in the engine cylinders.

The electronics detect the problem of a constantly lean fuel mixture and send a signal to the driver in the form of an illuminated Check Engine.

The way out of the problem in this situation is simple - the injectors need to be cleaned. But we recommend that this task be carried out at specialized service stations, where all the necessary equipment is available. In “garage” conditions, you will not achieve a good result, but will only permanently damage the injectors.

Oxygen sensor problem

On injection engines, regardless of its volume and number of valves (more about the engines that are installed on the Grant here), there is a large number of different sensors:

1. crankshaft position sensor,
2. oil pressure sensor, engine temperature,
3. finally, the oxygen sensor.

It is precisely the last one among all those listed that is the most vulnerable point not only in VAZ cars, but also in foreign cars. Due to a malfunction of the oxygen sensor (or, as it is also called, a lambda probe), the engine warning light may light up on the instrument panel.

Dismantling instructions

To dismantle the device, you must follow the instructions:

• First remove the cover of the fuse box located to the left of the steering wheel.
• Unscrew the three bolts securing the plastic lining of the control panel.
• Dismantle the lining itself, and then unscrew four more bolts of the tidy. Pull it towards you.
• Next, squeeze the connector with the wires and disconnect it from the control panel.
• Dismantle the unit and repair or replace it. Assembly is carried out in reverse order.

The principle of operation of the speed sensor is as follows: there is a certain mark on the gear wheel that generates an impulse using the DS when the wheel rotates. The speed of the vehicle is determined based on the frequency of the received pulses. As the frequency increases, the speed of the machine increases. The signal from the speed sensor, as well as from many others, is output to.

The fact that the DS on the Lada Granta is located low indicates that it is strongly exposed to water, sand and dirt. This is the main reason for its failure. The following symptoms indicate that the sensor responsible for the speed of the Lada Granta car is faulty:

• the speedometer needle is at zero while driving or does not always work;
• unstable idling;
• The speedometer readings do not correspond to reality;
• fuel consumption increases;
• engine thrust decreases.

Please note that unstable engine idle speed and an increase may also be due to a malfunction of the Lada Granta oxygen sensor, which consists of two devices: a control catenary collector located in the upper part, and a diagnostic one installed in the catenary collector behind the converter. They operate on the same principle and are interchangeable. The control oxygen sensor monitors the adjustment of the composition of the air mixture supplied to the injectors. The diagnostic oxygen sensor signals the presence of oxygen in the exhaust gases after the converter.
