How to Reset the On-Board Computer of a VAZ 2114

Operating instructions for the VAZ-2115 on-board computer.
Cars manufactured in the Russian Federation are equipped with a computer. The first on-board computer appeared on the VAZ-2114. In simple terms, the on-board computer can be considered a kind of electronic reference book on the condition of the car. The driver needs it in order to understand the condition of his car, as well as what faults have appeared in it.

The first on-board computers on domestic cars performed the following functions:

1. Controlling the amount of fuel poured into the tank.
2. An approximate calculation of the distance that can be driven with the remaining fuel in the tank.
3. Monitoring the temperature of the coolant in the engine, as well as preventing it from overheating.

The modern on-board computer on the VAZ-2115 is designed for:

• transmitting information about indicators “online”;
• displaying information on the information panel;
• reflections of route parameters, such as current fuel consumption, travel time, number of kilometers traveled, etc.;
• diagnostics of the engine condition with subsequent display of errors on the on-board computer screen.

Among other things, depending on the vehicle’s configuration, its on-board computer may receive the following data:

• information about the time of the next vehicle maintenance;
• information about the need for adjustments to certain vehicle functions;
• warning about the need to renew the insurance policy;
• information from the organizer;
• parameters at which the cooling system fan will automatically turn on.

Types of bookmakers

On-board devices are divided into several types. Injection or carburetor devices are suitable for the VAZ 2110, depending on the type of power system for the car. Additionally, devices are divided into stationary, installed only in specially designated places, or universal, of any size, which can be placed in any convenient place.

Among other things, there are devices that are suitable only for one model. For example, VAZ 20219, but it does not work on VAZ 2110. This may cause the device to display data incorrectly. It’s worth remembering this when purchasing and purchasing an on-board computer that can be installed specifically on these models.

The most common and convenient devices for the VAZ 2110 are simple State 110-X5 devices, the price of which starts from 2-3 thousand rubles. The bortovik is compatible with the old panel and has a number of simple functions, such as information on fuel consumption, coolant temperature in the tank, estimated power reserve and mileage until the upcoming maintenance, coupled with decoding engine errors.

Operating principle of the on-board computer

Cars such as the VAZ-2109 were equipped with devices that acted as routers. Let us remember that these were carburetor cars. But the VAZ-2114 and 2115 began to be equipped with injection power plants, which required the use of a completely different type of device.

Therefore, the main functions of the on-board computer on these cars are diagnostics, as well as control of the operation of almost all vehicle systems.

The principle of operation of the on-board computer on the VAZ-2115 is as follows:

• acceptance of signals using the control unit, their subsequent processing and output of the necessary information to the computer display;
• the ability to make some adjustments;
• processing of signals received from systems that are not controlled by the controller. If an abnormal situation occurs in the car, a sound signal will be sent to the on-board computer, and error information will appear on its screen.

Brief instructions for operating the on-board computer

When you purchase a VAZ-2115 car, you will receive instructions for operating the on-board computer along with it. It describes in detail what to do in various situations. And now it’s time to talk about how to properly use the on-board computer on the VAZ-2115. To do this you need:

• Study the instructions with the on-board computer information display turned on. Such an action is necessary if the bookmaker is endowed with numerous different functions, which are impossible to understand on your own;
• greatest attention should be paid to the symbols and icons corresponding to emergency commands;
• The operation of the VAZ-2115 on-board computer is regulated using a special panel with buttons. Once you understand what functions each button performs, it will be much easier to manage the bookmaker.

There is no need to memorize all kinds of error codes. It’s best to simply find the designations of all the errors on the Internet, where, by the way, they are freely available, print them out on a piece of paper and carry them with you in the car all the time. And when you see a particular error code on the computer information board, it won’t take you much time to understand what exactly it means, you just need to look at the previously printed list.

By the way, it often happens that the on-board computer issues a danger signal for absolutely no reason. The reason for this may be the on-board computer processor or some sensor that is not working correctly. Remember, no one is immune from electronic errors. Nevertheless, in the vast majority of cases, the VAZ-2115 on-board computer works quite correctly.

We present to your attention the most common error codes with their interpretation:

• 2 – on-board network voltage is exceeded;
• 3 – fuel level sensor does not work correctly;
• 4 – the sensor responsible for the temperature regime of the motor is faulty;
• 5 – outside air temperature sensor transmits warning signals;
• 6 – motor overheating;
• 7 – very low pressure is observed in the car’s lubrication system;
• 8 – some problems were discovered in the braking system;
• 9 – low battery charge.

If the numbers 4, 6 or 8 appear on the car’s on-board computer while driving, you should immediately stop, fix the problem and only then continue driving. But after this you will need to reboot the processor. The error can be reset by simply holding down the daily mileage key for a few seconds.

Meaning and interpretation of error codes

To read the faults, first consider the list with a table of UEr errors that self-diagnosis produces (the author of the video is Ivan Vasilyevich).

These codes can add up; if you see the number 6, this may indicate errors 2 and 4, or if the number 9 is displayed, errors 1 and 8.

In order to immediately read and decipher problems when diagnosing, it is advisable to download and always carry with you a printout with a description. When diagnosing using a computer, codes on engine 21124 may differ depending on the car model. To read the codes, you need to know how they are supposed to be deciphered. Errors must be reset after they have been deleted (the video was filmed and published by the KV Avtoservis channel).

What to do if the on-board computer on the VAZ-2115 stops working

Sometimes it happens that even though the car is in full working order, the on-board computer completely refuses to work.
What to do in this case? Of course, you can try to fix the problem yourself. But it’s still much better if a real specialist does this. It is he who will be able to reliably determine the cause of the device malfunction.

But before going to the service center, the first thing to do is check fuse F3, which could simply have blown. It is installed in the power supply circuit of the VAZ-2115 processor. If, after replacing the fuse, the on-board computer still shows no signs of life, you can also check the connectors connected to it. We repeat that if you are not an electrician, and generally do not have much knowledge of electronics, this task should be entrusted to a professional.

Remember, any malfunction that the on-board computer shows can be eliminated, just like a breakdown of the on-board computer itself. But, as they say, it is better to prevent a problem than to solve it later. Therefore, each car should be kept in good condition, undergo technical inspection on time and replace spare parts that are out of order. Among other things, it is better not to allow spare parts to break at all, but to replace them as they wear out. Only in this case will driving the car be safe from a technical point of view, and during the trip there will be no emergency situations associated with improper operation of the car.

Correct operation

With the right approach, the installed BC will not cause problems.
However, if it shows unreliable information, then it is worth removing the on-board computer and checking it for serviceability. How to remove the device is clear. After all, it has a disconnectable connector, so you need to dismantle it in the reverse order. The main thing to remember is that this is a fragile thing and can be broken. After dismantling, you should check the integrity of the soldering and wires and eliminate any breaks . Afterwards, put the device where it was before and use the working device again.

Connecting the VAZ-2114 on-board computer: connection diagram and error codes

Until recently, electronics in a car were a luxury, but today this is not the case. Increasingly, electronic devices are included in the basic equipment of vehicles. They simplify the life of the car owner, providing comfort when operating the car and monitoring the operation of various systems/components. Unfortunately, budget domestic cars (for example, VAZ 2115) lack this.

On-board computer VAZ-2114: installation and configuration

The standard equipment of this car allows the owner to monitor the situation based on basic instruments (for example, a speedometer). The accuracy of such measurements is relative, so an on-board computer is installed (for example, on a VAZ-2114).

Devices (for example, Multitronics, Gamma, Orion) differ in cost and functionality. If you connect an electronic controller, you will receive accurate information about the operation of car systems. By reading faults, the “head” will give a warning about potential problems in advance. The car owner will be able to prevent trouble and avoid more serious damage.

The basic on-board computer on the VAZ-2114 is represented by model 3857010. It is mounted on the panel on the right. If this is not provided, the manufacturer leaves a plug and a nine-pin connector underneath it. If you install this BC, the display reflects:

• duration of the trip (including and without stops);
• approximate average speed along the way;
• calendar and time;
• fuel used per trip (on average, overall and present);
• signal about a small amount of fuel assemblies in the tank;
• kilometers traveled en route;
• mains voltage (signal that it has dropped below the permissible level).

Before installing this and other models (for example, Multitronics), prepare for the procedure in advance.

Preliminary preparation

Preparing for installation

There are a few things you should think about and do before you begin installing BC.

1. Determine the set of features you want from the bookmaker. For this purpose, standard instructions are included with each device. You can also find a lot of information on the Internet.
2. For a VAZ 2114 there is no point in buying an overly complex system. But budget bookmaker models are not the best solution.
3. The optimal package includes a monitor, a set of cables and a processor.
4. Decide where the BC will be installed. The center console is best for this. But there must be enough free space for this.
5. If the center console doesn't fit, try the instrument panel. Although in this case an external housing will be required.

Connecting an on-board computer to a VAZ

If you decide to connect the device yourself, read the instructions (it is included with the unit). No special skills are needed, but we recommend studying the algorithm of actions in advance and finding a video with a detailed description of the work. The “luxury” configuration includes AMK-211501 (added with functionality for ECM diagnostics). It allows you to preheat the spark plugs and automate the operation of the fan, thereby regulating the temperature.

Connecting the on-board computer 2114 helps to monitor the current state of car systems. Failures can be deciphered using codes. If the “No errors” signal is on, everything is fine. The list of identifiers is large - below we list only a few of them:

• 0172 (enriched fuel);
• 0134 (oxygen sensor not active);
• 0300 (ignition with “skips”);
• 0505 (idle speed control malfunctions);
• 0116 (refrigerant temperature error);
• 0340 (phase sensor error).

How to withdraw BC

Car owners sometimes decide to replace the pre-installed factory option with an alternative one. If the device is under warranty, it will be void when removed. The work begins by removing the “-” terminal of the battery, so as not to damage the wiring and not get an electric shock. Remove the radio from the console, remove the outer panel of the audio system and remove the music unit with all the wires. In the resulting hole there will be a “sidewall”. If you are not going to install a new device, connect the wiring (or install a new BC). Reassemble everything in reverse order.

Installing BC on a car

Having decided on the choice of device, you can proceed to installing the BC. First of all, you should study the manufacturer's instructions, which should be included in the kit.

As for the installation location, this is usually the center console. By the way, you should prepare the installation shaft for the BC in advance. If for some reason such installation cannot be implemented (the seats are occupied by other devices), you can buy an on-board computer with a remote housing.

It is also important to consider that even after installing the on-board computer, you will need to configure it. In other words, once the wiring is connected, the computer will not immediately display accurate information without adaptation.

• Let's move on to connecting the on-board computer. First of all, the on-board computer 2114 or on-board computer 2115 is usually placed in a standard and previously prepared place. This option will be the best. Before starting work, you need to disconnect the terminals from the battery.

To connect the on-board computer, you need to supply 12V power to the device and also connect ground. To automatically start with the engine, power is supplied from the ignition. By the way, when powered by side lights, the computer screen may glow less brightly, which is quite convenient in the dark.

If the model supports receiving a signal from a fuel level sensor, you should not ignore this possibility and connect this sensor to the BC. You also need to connect the controller’s diagnostic line “K-line”.

Typically, the connection diagram for an on-board computer comes down to switching the BC and the diagnostic connector. In fact, a standard four-pin block is connected to adapters, and power is taken from the cigarette lighter, autostart is implemented through the ignition switch, ground is taken from the body, etc. If the block in a particular on-board computer does not fit the VAZ 2114 connector, you can use adapters.

Malfunctions and settings of the on-board computer on the VAZ-2114.

Often no additional manipulations are required - just enter the parameters according to the manufacturer's instructions. If the BC does not function, check the fuse and wires for integrity. If there are glitches in the system, try to reset it. To do this, press the reset button, disconnect the connector or battery terminals.

If it is necessary to reset errors, warm up the engine, disconnect the battery for 15 minutes and connect it back. The key in the ignition switch is turned, stopping it in the pre-start position. After turning on all the lights and indicators on the dashboard, leave the key for a couple of minutes, then return it back.

After completing the steps described above, start the internal combustion engine and let the car idle without pressing the gas pedal. Repeat the procedure several times to reset the system. If the method does not work, use the “software” analogue. When a signal appears on the display, understand the situation.

Connection diagram for on-board computer on VAZ 2114

• disconnect the battery terminals;
• remove the cover from the “tidy”;
• provide access to the connector responsible for diagnostics;
• remove part of the console;
• connect a meter-long piece of wire (see image below);

Benefits of the on-board system

It allows you to monitor the operation of the car “here and now”, thanks to communication with the control unit and sensors. Indicators are displayed on the screen in an adapted form so that the driver can quickly navigate the situation. BC ensures the collection, correction, analysis and issuance of accurate data on the condition of the machine. Theoretically, all data can be calculated on your own (this is inconvenient). Promptly receiving technical data (for example, engine temperature and fuel consumption) in real time gives the driver the opportunity to take the necessary corrective measures in a timely manner.

Installation

Installation process

To connect an on-board vehicle to your VAZ 2114, you don’t have to be an excellent specialist. Following the instructions, you can do all the work yourself. Give this issue enough time and effort.

1. First of all, remove the plug located on the instrument panel. Let's start with the fact that you have found a place for your on-board computer.
2. After removing the plug, look for a harness with a nine-pin connector. It is available on all VAZ models, so your “fourteenth” will not be an exception.
3. Now connect this connector to the on-board computer.
4. One of the most important areas of activity is the K line.
5. To do this, take a wire about 1 m long and connect it to the second pin of the nine-pin connector block.
6. We connect the other end of the wire to the diagnostic block. It is located directly under the dashboard. To make it easier for you, we recommend that you detach the panel on the right side.
7. If you have a Euro 2 connector, the cable with the diagnostic connector is connected via M.
8. If the unit is Euro 3, you will need socket number 7.
9. In some cases, on a VAZ 2114 the Euro 3 unit is mounted upside down. Therefore, be sure to pay attention to this when connecting so as not to confuse anything.
10. After connecting the on-board computer, install it back in its intended place and check its operation.

Operating principle of the on-board computer

Cars such as the VAZ-2109 were equipped with devices that acted as routers. Let us remember that these were carburetor cars. But the VAZ-2114 and 2115 began to be equipped with injection power plants, which required the use of a completely different type of device.

• acceptance of signals using the control unit, their subsequent processing and output of the necessary information to the computer display;
• the ability to make some adjustments;
• processing of signals received from systems that are not controlled by the controller. If an abnormal situation occurs in the car, a sound signal will be sent to the on-board computer, and error information will appear on its screen.

The main differences between the BC and the instrument panel

The computer is able to inform the driver about actual and average fuel consumption. This information is especially relevant during long journeys. Plus, the BC is able to monitor the temperature of various vehicle systems and inform the driver about the danger of overheating.

Some modern devices also warn the vehicle owner about the likelihood of ice forming on the road. The instrument panel lacks all these abilities.

The main task of any BC is to collect the most important parameters of vehicle systems, process data and output the final information in a form accessible to the driver.

It is quite obvious that with such an assistant, any trip will become safer, more convenient and more economical in terms of fuel costs. Also, experienced motorists know that the speedometer of any car counts the engine speed, processes the data received and displays the final result. But, if you install larger diameter wheels on your car, the actual speed will increase, but the speedometer will not display this. The on-board computer will protect against such incidents, unlike the control panel.

Hi all! We have such a BC and it seems to work, it shows something, but when switching modes absolutely nothing happens... Here is information about this, found, among other things, by one of the drivers:

Cruise computer CC911

On-board computer for cars VAZ 2110 family with BOSCH controller М1.5.4, М1.5.4N (JANUARY 5.1)

The CC911 on-board computer (computer) is connected to the vehicle's electronic control unit (ECU) and allows:

Operational monitoring of parameters when parking and while driving (on-board voltage, fuel consumption, coolant temperature, driving speed). Quick car diagnostics using error codes. Erasing fault codes from the ECU memory. ATTENTION! The on-board computer is not a measuring device; it only displays information contained in the vehicle's ECU. Therefore, the accuracy of the displayed parameters is determined solely by the vehicle’s ECU with which the on-board computer works.

Control is carried out with a button.

The built-in buzzer confirms the pressing of the control button and signals that the controlled parameters are exceeded.

When the side lights are turned on, the brightness of the indicator automatically decreases.

The computer automatically turns on when the ignition is turned on and goes into the data display state of the last selected mode (after turning off the vehicle's on-board network, when the computer is turned on, the F1 mode data display is set).

When the ignition is turned off, the indicator goes off and the computer enters power saving mode.

If the computer does not turn on, check:

presence of supply voltage, connection to the data line (including the presence of a jumper between the 9th and 18th pins of the immobilizer connector, if it is not included in the vehicle). If there is no connection to the data line, when the power supply is connected, the indicator will display mode number F1, and after 5 seconds the computer will turn off.

Operating mode selection

To change the mode, briefly press the control button. The computer enters the mode number indication state. In this case, the indicator will show the current mode number, and the buzzer will sound a sound signal in accordance with the current mode number. Each subsequent press of the button (with an interval between presses of no more than 2 seconds) increases the mode number by one as displayed on the indicator and is confirmed by a single sound signal (when switching to mode F6, a long sound signal is heard). 2 seconds after the last button press, a beep will sound with the number of the selected mode, and the computer will return to the data display state.

F1 - fuel consumption in liters from the moment the engine starts. F2 - vehicle speed in km/h. F3 - on-board voltage in volts with an audible warning about exceeding permissible values. F4 - coolant temperature in degrees Celsius with an audible warning signal when the permissible value is exceeded. F5 - instantaneous fuel consumption in l/100 km when driving or in l/hour when parked. F6 - fault codes (sequentially in creeping mode). Holding the button for a long time (4 seconds) in F6 mode clears the ECU fault codes (the CHECK ENGINE symbol on the instrument panel goes out).

ATTENTION! It is not recommended to clear fault codes on your own to avoid losing necessary information when repairing your car.

Measuring fuel consumption per trip

To measure fuel consumption for a trip, while in the F1 mode data display state, long press the control button (holding it for 2 seconds until a long beep) to reset the pressure gauge. Stopping the engine does not reset the indicator, and the next time the engine is started, the fuel consumption count will continue.

Sound signal about exceeding the set speed

To turn on the audible alarm for exceeding the set speed, in the F2 mode data indication state, accelerate the car to the required speed and long press the control button (hold for 2 seconds until the buzzer sounds) to record the indicator readings. The dots on the indicator will start flashing. Now, when the fixed speed value is exceeded, a pulsating sound signal will sound.

The sound alarm is also turned off when the set speed is exceeded in the F2 mode data indication state by long pressing the control button. Stop confirmation: a long beep and the dots on the indicator go out. When the ignition is turned off, the sound signal is automatically turned off.

Alarm of monitored parameters beyond the permissible limit This function is active only when the engine is running.

When the coolant temperature exceeds 110 ° C or the voltage of the on-board network exceeds 11.7 ... 14.8 V, the ECU goes into the emergency mode data display mode and the buzzer emits a series of warning sounds when the parameter goes out of tolerance (3 signals in a series when the voltage deviates and 4 signals in a series when there is a temperature deviation). When you press the control button for a long time, the alarm about violation of this parameter is turned off until the next time it is turned on.

Installing a computer on a machine

Unqualified connection of additional devices to the electrical equipment of the vehicle can lead to malfunction of the electrical equipment and an emergency situation.

The manufacturer is not responsible for the consequences associated with incorrect connection of this device.

The computer is installed in the front of the car next to the clock instead of a plastic cover.

Do not connect or disconnect cables while the ignition is on.

The black wire is grounded. Red wire - not disconnected + 12V White wire - this is the serial data line. Connects to the “M” socket of the diagnostic unit located on the VAZ 2110 under the steering column. If there is no communication between the ECU and the ECU, check for the presence of an immobilizer in the vehicle and, if not, the presence of a jumper between pins 9 and 18 of the immobilizer connector.

Blue wire - size + 12V.

Strictly following these instructions, I tried to switch between modes, find out the range, and so on, but the numbers are still the same. Does anyone know anything about this? As far as I understand, the BC must connect to the ECU and read data from it accordingly, and since there are no changes, maybe a wire is broken somewhere or something like that...

Hi all. When I bought the car, the former owner gave me a bag with a service book and user manual. When I came home, I threw this bag into the nightstand and didn’t even look at what was there and how it was, somehow I didn’t need it. And then the other evening I came across the same bag and decided to check its availability! To be honest, it was interesting to learn about the life of the car during the first kilometers of its operation. And in the operating instructions I came across a description of the on-board computer that was installed on the car in my configuration. I think that when buying a used car, not everyone receives this documentation and sometimes questions arise, how to set up the onboard vehicle? You can use the "typing" method or search online on Google. There are also large varieties of on-board computers, such as those that were installed at the factory and those that you can add on. Therefore, I decided to delete the instructions, maybe this information will help someone with the same on-board computer.

In the version, an on-board computer (BC) is installed instead of a clock. MK has 15 functions, divided into 3 groups. Group selection is performed using buttons 1, 2 and 3.

In each group, functions are divided into basic and additional. Scrolling through the main functions is carried out in a ring using buttons 1, 2 and 3. Additional functions are scrolled using button 5. When the ignition is turned off, the computer is always in the “Current time” mode. With the battery removed, the clock frequency and all accumulated parameters are stored for at least 1 month. SETTING UP COMPUTER FUNCTIONS Correcting the clock Press button 4 in the “Current time” mode. At the sixth hour signal, press button 1, the seconds will be reset to zero and the hours will be rounded.

Setting the current time (calendar) Press button 4 in the “Current time” (“calendar”) mode. Use buttons 5, 6 to set the desired hour (day). Press button 4. Use buttons 5, 6 to set the desired minutes (month). Press button 4 to complete the time (calendar) setting.

Setting an alarm Press button 4 in Alarm mode. Use buttons 5, 6 to set the desired hour value. Press button 4. Using buttons 5, 6 set the desired minute value. Press button 4 to complete the alarm setting. In the “Time” mode, the alarm symbol lights up (the alarm is on).

Turn off the alarm Press button 4 in Alarm mode. Press button 1 to turn off the alarm. The digital digits will show “—.—”, and in the “Current Time” mode, the alarm symbol will not light up (the alarm is disabled).

Adjusting the brightness of the indicator light When the side lights are on, the level of illumination is adjusted by a dimmer on the instrument scale. When the side lights are turned off, the backlight level is adjusted by software: - press button 4 in the “Travel time with stops” mode. All individual segments (icons) will be displayed on the indicator, which is a sign of the backlight level adjustment mode, and the number corresponding to the backlight level as a percentage of the maximum value will be displayed in digital figures; — use buttons 5, 6 to set the desired level of backlight brightness; — press button 4 to exit brightness adjustment mode.

Calibrating the fuel level sensor To correct it, you need to drain all gasoline from the tank. Press and hold button 4 for more than 2 s in the “Fuel level” mode. The indicator will show a flashing “0”. Press and hold button 3 for 1 second until a confirmation beep appears. After this, a flashing number “3” will appear on the indicator. Using a measuring cup, pour 3 liters of gasoline into the gas tank, wait until the fuel level sensor calms down, press and hold button 3 for 1 second until a confirmation beep is heard. Continue this procedure until the maximum value is 39 liters, after which the computer will automatically exit the mode.

Setting the speed alarm Press button 4 in the “Medium speed” mode. Use buttons 5, 6 to set the required speed threshold. Press button 4 to exit the overspeed alarm setting mode.

What to do if the on-board computer on the VAZ-2115 stops working

Sometimes it happens that even though the car is in full working order, the on-board computer completely refuses to work.
What to do in this case? Of course, you can try to fix the problem yourself. But it’s still much better if a real specialist does this. It is he who will be able to reliably determine the cause of the device malfunction.

But before going to the service center, the first thing to do is check fuse F3, which could simply have blown. It is installed in the power supply circuit of the VAZ-2115 processor. If, after replacing the fuse, the on-board computer still shows no signs of life, you can also check the connectors connected to it. We repeat that if you are not an electrician, and generally do not have much knowledge of electronics, this task should be entrusted to a professional.

Remember, any malfunction that the on-board computer shows can be eliminated, just like a breakdown of the on-board computer itself. But, as they say, it is better to prevent a problem than to solve it later. Therefore, each car should be kept in good condition, undergo technical inspection on time and replace spare parts that are out of order. Among other things, it is better not to allow spare parts to break at all, but to replace them as they wear out. Only in this case will driving the car be safe from a technical point of view, and during the trip there will be no emergency situations associated with improper operation of the car.

The serviceability of your car is a guarantee of the safety of both the driver and passengers.

Using the codes, you can find out the status of the fuel system, power supply and other important components.

Some luxury variants of the VAZ 2114 come with a standard BC, while other models have space to install your computer and all the connectors you need. Installing a quality device detects the vehicle at an early stage and corrects it in a timely manner.

STAT instructions for on-board computer for VAZ 2114 and 2115

makes it possible to study all the parameters and resources of the aircraft. The principle underlying this device is to transmit sensor readings through a control unit. The data is then processed and displayed on the screen in the form of codes. Using BC allows you to diagnose systems that are not recognized by the controller. Emergency situations are indicated by a symbol that is displayed on the board and accompanied by an audible signal.

Basic data is displayed:

• Speed ​​limit, fuel balance, travel time;
• Rotation power supply;
• Engine condition and engine temperature;
• Fuel consumption and mileage that can bring cars into balance;
• Mains voltage;
• Coolant temperature and throttle position;
• Error codes;
• Air circulation, distance traveled, average speed and other useful parameters.

How to Reset the On-Board Computer on a VAZ 2114

Nowadays, the computer is a trivial device that a huge selection of people encounter comfortably and in a large number of vehicles. Speaking more specifically about car drivers, the computer, otherwise known as the more familiar one, has become indispensable for everyone present, since only with its help can one control the operation of most devices.

Video about the operation of an abnormal BC on a VAZ-2114:

Speaking about cars produced in our country, the first of the AVTOVAZ family was the VAZ-2114, which was installed directly from the factory fighter, which could notify the driver about all events, both outside and in the interior of the car. Below we will carefully analyze what a flyer requires and also analyze a short abstract for it.

The usual place in the instrument panel. There is a form in the photo.

The first version of the aircraft installed on the VAZ-2114, although it had small functions, easily took into account the basic parameters of the car:

• Fuel level control and its calculation of the number of kilometers traveled - this function allows the driver to make a decision about refueling in advance.
• Antifreeze Temperature Monitoring - This feature eliminates engine overheating with timely driver information.
• Diagnostics of individual vehicle components - Allows you to accurately and easily find and fix problems.
