How to set up the on-board computer vaz. On-board computers for VAZ, Lada (injector)

The on-board computer VAZ 2114, in fact, is the "brains" of the vehicle. Thanks to this device, the operation of the main systems and units of the car is controlled, and if it breaks down, the driver may encounter certain difficulties. You can learn more about the main characteristics, as well as malfunctions of the car's BC, from this material.

Characteristics of BC

Before choosing which BC is better to install so that it works well, let's look at the characteristics of the device.

Purpose

The purpose of the on-board computer VAZ 2114 is to inform the car owner about the technical parameters of the vehicle. This is carried out as a result of the fact that the standard on-board computer VAZ 2114 is connected to the control unit through a special diagnostic line. The latter, using coded pulses, warns the driver about fuel consumption, engine speed and other parameters. The BC receives most of the information from sensors.

As a rule, the device is mounted on the control panel, above the air deflectors. In machines that do not have a BC, a plastic plug is located instead.

Main settings

The on-board computer on the VAZ 2114 allows you to determine the following parameters:

• vehicle speed;
• the volume of fuel in the tank and its consumption, as well as the mileage that the car can run on this fuel;
• time spent on the passage of a particular path;
• crankshaft frequency;
• the degree of heating of the motor;
• temperature indicator in the car;
• total mileage of the vehicle;
• voltage in the car's electrical network;
• the degree of heating of antifreeze in the system;
• what position is the throttle valve in;
• overall air flow;
• combinations of faults, as well as their decoding;
• fuel consumption in general;
• the amount of gasoline spent for the last trip;
• average vehicle speed and other useful information.

Possible malfunctions

If the on-board computer does not work, then this may be due to such malfunctions:

• connectors and power wires are incorrectly or unreliably connected;
• the safety element responsible for the functionality of the device has failed (there may not be a fuse directly on the BC, you need to check the operating instructions);
• incorrectly configured or adjusted device, for this you need to read the instructions or manual.

If the VAZ 2114 on-board computer does not work well, first of all it is necessary to check the integrity of the contacts and clean them if they are oxidized.

DIY Connection Guide

The procedure for installation, dismantling and connection can be carried out at home. Before you take on this work, weigh your strength, because the computer is a serious matter, because it is he who is responsible for many processes. Moreover, it is directly connected with the control unit (the author of the video is the Homemade Homemade channel).

BC installation

Further, we propose to find out how the on-board computer is installed on the VAZ 2114. For the VAZ 2114, you can use the BC Gamma or any other adapted to the technical characteristics and features of the vehicle.

So, how to install the device with your own hands:

1. First you need to choose a place for installation. As we already reported, it is located on the center console and is hidden with a plastic plug, so it must be dismantled.
2. For easier installation, this car model has a special wire connector with a block with nine pins. These contacts must be installed in the connector located on the back of the BC.
3. Next, activate the K-line. To do this, connect the brown wire to socket M of the Euro2 plug or to socket 7 of the Euro3 plug. As for the reverse end of the cable, it must be installed in slot 2 on the plug. When installing, be careful, it is possible that the pad is installed upside down in the car.
4. Now you just have to install the BC in the landing site and test the device for performance. It should be borne in mind that, depending on the modification of the device, such a BC can also be installed on a vehicle with a carburetor. But one computer will not be enough, it will be necessary to install additional devices and devices (the author of the video is the MrStas ZoRrO channel).

Dismantling BC

It often happens that the BC does not suit car owners for certain functions, or it simply does not work correctly and needs to be replaced. In this case, you can dismantle the BC at home, there is nothing complicated about it. Before removing the device, it is necessary to make sure that its dismantling will not affect the warranty service of the vehicle. Of course, this applies to newer cars that were purchased in the cabin. We are talking about this because the dismantling of the BC in any case will affect the warranty, this must be taken into account.

So, detailed instructions for dismantling the on-board computer with your own hands:

1. Before proceeding with the removal process, it is necessary to de-energize the vehicle. To do this, simply disconnect the battery, namely, remove the negative terminal from it.
2. After that, the audio control panel is dismantled. This is also not difficult, when removing, be careful not to damage it.
3. Next, you need to dismantle the car radio itself, for this you need to disconnect the connected wiring from it.
4. After the radio tape recorder is removed, you can stick your hand through the opened hole and disconnect the latches of the unit of the device itself. Having done this, it is necessary to dismantle the BC as carefully as possible and disconnect all connected wiring from it.
5. After performing all these actions, it is necessary to remove all auxiliary devices and devices that are connected to the BC. If you decide to replace the device with a new one, then at this stage a new device is installed and connected in accordance with the operating and installation instructions. If you just decided to dismantle the BC, then just connect the audio system and install it in its place.

Issue price

The cost of the device depends on many parameters, so it is impossible to unambiguously name the price that is relevant for all on-board computers on the “fours”. The price of the device is determined in accordance with the manufacturer of the computer, its technical parameters and characteristics. We want to say right away that we would not recommend giving preference to cheap options, since BCs are the “brains” of a car, and you can’t save on this.

Video "How to properly set up the BC in the VAZ 2114"

Detailed instructions for setting up the device in the domestic four with a description of all the nuances are given in the video below (the author is the MegaSirius12 channel).

Almost all modern cars are equipped with an on-board device. This device provides the machine with many useful functions. With it, you can find out the daily mileage of the car, instantaneous fuel consumption, air temperature, fuel supply in the tank. Among other functions - additional operating parameters - air consumption, crankshaft and damper position, and other data.

However, the most useful function of an on-board or trip computer is to provide error information. The device can find out the error number that occurs during engine operation and display it on the screen without additional diagnostics. This allows you to troubleshoot, avoiding paid diagnostics or unexpected repairs.

Some models of cars released from the factory do not have this useful device, which makes it difficult to maintain the car. Therefore, the owners tend to carry out their own tuning of the vases. Putting an on-board computer on a VAZ 2110 with your own hands will not be any particular problem. With the correct connection, the operating time will not take more than an hour. The article will show how to install and configure the device on the VAZ 2110-2111, and also tell you about the models and prices of on-board computers.

On-board devices are divided into several types. On the VAZ 2110, injection or carburetor devices are suitable, 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 arbitrary size, which can be placed in any convenient place.

Among other things, there are devices that are suitable for only one model. For example, VAZ 20199, but it does not work on VAZ 2110. This may be the reason why the instrument does not display data correctly. It is worth remembering this when buying and purchasing an on-board computer that can be installed on these models.

The most common and convenient devices for the VAZ 2110 are simple State 110-X5 devices, the price of which starts at 2-3 thousand rubles. The board 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 range and mileage to the upcoming maintenance, coupled with decoding engine errors.

It is best to give preference to more expensive devices such as Omega 168, Orion or Mutltronics. Such devices have an expanded set of useful functions that will greatly simplify the operation of the car. And you will not be afraid of how much such an on-board computer costs. The maximum cost of advanced BCs, which come with a dashboard that simplifies installation, reaches 10-12 thousand rubles.

The main differences between a BC injector and a carburetor

The main differences between bk, depending on the type of food, are the on-board capabilities for the VAZ 2110. The carburetor type is the simplest. The main reason is that carburetors are more mechanically regulated, and electronics is assigned a secondary role. Therefore, its standard set of functions is extremely small. You can learn about:

• time of day or set an alarm;
• current and average fuel consumption, as well as power reserve;
• average speed and driving mode;
• engine or outside air temperature;
• diagnostic information that allows you to find out about the engine operation error and decode it.

Disadvantages of BC injector

Some VAZ 2110 models are equipped with a standard on-board computer. This model has a number of disadvantages and limitations. For example, the model interacts poorly with the electronic control unit (ECU) and does not allow receiving data through a special diagnostic connector. However, only motorists, on-board computer in the state, face such a problem. In addition, this is treated with a standard flashing of the factory settings.

If the BC is installed separately on the VAZ 2110, then it can be easily customized. Provided that the connection is correct, the device will not cause problems. If, nevertheless, there are difficulties, for example, the Check light comes on, and the diagnostics shows that such an error code does not exist.

This means that the contacts of the on-board computer may come off or a failure in the electronic system may occur. You need to restart the BC or turn it off for a few minutes. Next, we reconnect and configure the device according to the instruction manual.

• some models of bortoviks do not allow reading errors;
• incorrect connection of the computer to the VAZ 2110 can cause errors in the ignition system;
• shows incorrect fuel consumption values ​​due to a malfunction of the mass air flow sensor.

Rules for moving on a car with an injector

A car equipped with an injector is less susceptible to ambient temperatures. However, in severe frost, the injection Lada also has difficulty starting. Here it is worth using the on-board computer with the function of heating candles. Every time the temperature drops below a certain value and the car is turned off, a special heating of the tips is carried out to ensure a stable start of the engine.

Also, the engine on the VAZ sometimes overheats, which can cause valve burnout and costly overhaul. However, this is possible if the cooling system malfunctions. If necessary, you can activate the Tropic function for the on-board computer VAZ 2110. When the temperature reaches more than the value set by the owner, the forced cooling fan turns on.

Pros of bookmaker

Installing a computer on a VAZ 2110 will open up a lot of good options and has a huge number of advantages:

• the presence of a trip computer allows you to find out about the power reserve;
• the ability to combine a computer and a navigator;
• the option of heating the candles of the disabled car;
• the ability to check for errors and fix them immediately. Replacing the bearing that caused the failure is significantly
• cheaper than a major overhaul.

Installation of BC for the injector

Connecting the on-board computer is quite simple. Several models are offered on the VAZ 2110 - regular, which takes the place of standard watches or universal ones, which can be located at your discretion.

If necessary, you can install an on-board computer in addition to the standard one. This will save space on the panel. For example, the Sigma or State computer is installed on the VAZ 2112 instead of the standard plug of the SAUO block and there is no need to desolder the contacts. It is necessary to connect three contacts - 12 volt, K-line and ground.

User manual

Additionally, it is worth setting up the computer for the VAZ 2110 after all devices are installed. On the device, as a rule, there is a special cross. These buttons help you configure the device. For example, to connect a fuel level sensor, drain the tank, turn on the device, press the diagnostic button.

The device will analyze, and then a numerical designation will appear on the display. This amount of gasoline should be poured. The computer will then move on to another analysis phase. After its completion, you can fill in a full tank. A complete set of settings is indicated in the instruction manual for a particular device and make a choice in favor of the desired functions.

Proper operation

With the right approach, the installed BC will not cause problems. However, if it shows false information, then it is worth removing the on-board computer and checking it for serviceability. How to remove the device is understandable. After all, it has a switchable 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, check the integrity of the soldering and wires, eliminate gaps. After that, put the device where it stood before and use the serviceable device again.

Still, some 15-20 years ago, a computer in a car was considered a luxury element and was installed on cars of the top manufacturers and trim levels, which, of course, could not be said about representatives of the domestic market.

Video report on the installation of the on-board computer on the VAZ-2114

But time goes by, technologies and cars change, and today, anyone can afford to install an on-board computer and install it on almost any car model. Because it is with these devices that it is possible to monitor the status of all components and assemblies, as well as control the operation of systems as a whole. Below we will tell you how to install an on-board computer on a VAZ-2114 yourself.

Why do I need a BC on the VAZ-2114?

After installing the BC (on-board computer - approx.) on your car, you will be able to monitor the operation of all systems in real time, receiving all the information directly on the screen with accuracy.

On-board computer readings

A large number of modern BCs are capable of displaying the following information:

• Real vehicle speed.
• Mileage.
• Average speed.
• The remaining amount of fuel in the tank.
• The distance that the car can travel on the remaining fuel.
• Engine revs.
• Coolant temperature.
• Time spent on the trip.
• Indicators of average and instantaneous fuel consumption.
• The temperature inside the cabin and engine.
• Battery voltage.
• Air flow.
• Throttle position.
• Display of error codes (their voice guidance is not found on all models - approx.).

Which BC to choose?

The range of available products for the VAZ-2114 today is quite large, however, it is not worth taking the cheapest and the first one that caught your eye again, it is best to first of all pay attention to the following list:

Do not be afraid that the cost of some models can be about 5,000 rubles (and even more with certain options), because in this case you primarily pay for the functionality, stability and accuracy of the information displayed on the screen.

The difference between a separate BC and a BC on the control panel

There are many supporters and opponents of a separate on-board computer on various forums, the latter consider such a device to be superfluous, showing the sufficiency of the data that is displayed in the instrument panel window.

We will definitely tell you for sure that such a judgment is erroneous, because the “regular” BC, if it can of course be called that, is not capable of displaying even 1/10 of those functions that its counterpart is capable of. And this is due simply to the fact that the amount of information coming from the ECU to the control panel simply has nothing to process, when, as in the BC, this is done by a special processor that simultaneously calculates information.

Preparing for installation

Before proceeding with the installation, you need to perform some preparatory work:

1. Decide what parameters you want to receive from the BC, because the number of connected wires depends on this choice. To do this, we suggest that you read the instructions in more detail, and in its absence, information can always be found on the Internet.
2. Decide on the place of installation of the BC, and if this is a regular place on the VAZ-2114, then the model should be selected in the appropriate size.
3. Remember that after installing the BC, it will periodically need to be connected to a computer or laptop to download updates, so it’s still not worth it to tightly seal and fasten it at the installation site.

Dismantling the old on-board computer

If a regular BC is already installed on your car, most often with the same name “State”, then you still want to change it, because the information that it can transmit and modern analogues are very different.

1. Disconnect the negative cable from the battery. This is necessary in order to exclude the facts of a short circuit during dismantling.
2. Remove the radio, after removing its protective apron.
3. When nothing interferes, you can proceed to disconnect all the wires.
4. If they are successfully disconnected, and the radio tape recorder is dismantled, you can carefully disconnect the BC mounts.
5. After it is dismantled, inspect all wires for damage and corrosion.
6. If some time passes before installing a new computer, it is best to wrap all the contacts with insulating tape. However, when the work is done immediately, there is no such need. How to properly install the BC on the VAZ-2114 is written below.

Step-by-step procedure for installing an on-board computer on a VAZ-2114

In order to install an on-board computer in a car system, you do not need to be an expert in this field, just a little attention and time is enough.

At the time of connection, check everything for correct installation and for the accuracy of the BC operation with the engine running.

conclusions

As you can see for yourself, in order to install the BC yourself with your own hands, no special skills are required, but it is enough to strictly follow our instructions.

The seven keys are used to select the desired group of functions and to select the functions within the group and have the following designations: "T", "KM / H", "KM", "L", "L / 100", ECU, H. The "START" key is used to determine the start of shutdown and reset the accumulated parameters, to fix the parameter value in the correction mode and to set or delete the parameter control mode. The "" and "-" keys are used to increase or decrease the parameter value in the parameter correction mode and view diagnostic information. The display mode switching map is shown in Appendix B. When the ignition is off, the indicator displays the current time of day, the previously set alarm will sound for the set time. To reset the alarm sound, press the START button. When any key is pressed, except for the "-" and "" keys, the indicator lights up. The selected function determines the appearance and combination of icons displayed on the indicator, as well as symbols for the units of measurement of parameters. Display of parameters: "Current time of day", "Day time without stops", "Total travel time" is accompanied by a flashing dot. When the alarm is set, the current time display is accompanied by a bell symbol. The computer controls the following parameters:. the maximum speed of the vehicle; on-board network voltage; mileage of the car on the remaining fuel in the tank.

Figure 1 When the monitored parameter is outside the set value: the speed limit is between 20 and 200 km / h depending on the installation, the mileage on the remaining fuel is less than 50 km, the voltage of the on-board network is lower than 10.8 V or higher than 14.8 V, bell symbol “Starts flashing and an audible signal is generated: for the first two parameters with a duration of 3 s and 15 seconds, the pause is repeated twice. If the voltage is on, then the sound signal is generated with a delay of 10 s and a duration of 5 s and a pause of 5 s, the sound signal is repeated three times. The sound signal is accompanied by the display of the value of the monitored Parameter Reset the sound signal by pressing the "START" key. After resetting the sound signal, the indication of a parameter that has exceeded the set value is accompanied by a flashing “bell” symbol. When the parameter is normal, the alarm stops. To set or delete the parameter monitoring mode, it is necessary to set or reset the bell symbol in the monitored parameter display mode by pressing the "START" button.

The "" or "-" keys set the required parameter value. When you hold the "" or "-" keys for more than 0.5 seconds, the auto-repeat mode is activated. The clock is set according to the exact time signals as follows: in the Time of Day mode, press and press the START button, and at the sixth time signal, press the H button, and the minutes and seconds are reset. If the value of the "Current time of day" parameter coincides with the set alarm time, three melodic sound signals lasting 30 seconds each with a period of 1 minute are displayed. The alarm setting is reset as follows: In the Alarm display mode, press and press the START key, and then press the H key. In this case, the symbols "" are displayed in digital numbers, and the symbol "call" is absent in the "Current time of day" mode.

3.3 Clock correction

To reduce the error of the clock, you can enter a correction factor. To do this, press and hold the "START" button for 2 seconds in the "Current time of day" display mode. the symbol “C” and the value of the correction parameter will appear on the indicator. Press the "" or "-" keys to enter the desired coefficient value, and by pressing the "START" key, exit the correction mode. Are the maximum values ​​of the correction factor equal? 31. One unit of the correction factor equals a clock change of 0.35 seconds per day for positive values ​​and 0.18 seconds per day for negative values.

3.4 Setting the speed limit

Enter the speed limit setting mode by pressing the "START" button in display mode parameter "Average shutdown speed". At the same time, the speed limit flashes on the display, when it is exceeded, an audible warning is generated. Change the speed limit value by pressing the "" or "-" keys in 5 km/h increments from 20 to 200 km/h. Exit the setting mode by pressing the "START" button.

3.5 Indicator modes

When the instrument illumination is on, the illumination level is controlled by the vehicle's dimmer dial. With the lights off and the ignition on, adjust the backlight level as follows: In the "Total off time" display, press and release the "START" button. In this case, 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 numbers. Use the "" or "-" keys to set the desired backlight level. Each time you press the keys, the backlight level changes by 5%. When you hold down the keys for more than 0.5 seconds, the auto-repeat mode is activated. The set backlight level is saved until the next correction. To exit the setting mode, press the "START" button.

3.6. Setting the fuel level table

Tables of indications of the tested device are entered into the computer memory with a resolution of 3 liters (fuel level values ​​at intermediate points are calculated by interpolation). Depending on the type of vehicle and the type of instrument cluster installed on the vehicle, in order for the computer to correctly read the fuel level in the tank, it is necessary to install one of the fuel level tables stored in the computer's memory. The vehicle may be equipped with a combination of electromechanical devices. generating a fuel level output signal with a maximum voltage of more than 5 V or electronic instrument clusters that generate a fuel level output signal with a maximum voltage of up to 5 V (a distinctive feature of these instrument clusters is the presence of a liquid crystal odometer). The procedure for setting the type of instrument clusters and the corresponding fuel level table is as follows: a) disconnect the "Battery" circuit (remove the "-" terminal of the battery or disconnect the wiring harness connector from the computer); b) press one of the following keys to select the instrument cluster type:. combination "L" of electromechanical devices; "L/100". a combination of electronic devices; a combination of cars "GAZ-3110" "KM"; c) while holding the selected key, connect the “Battery” circuit (connect the wire harness connector to the computer) and after 2 seconds press the key.

3.7 DUT taring

Due to the fact that the DUT of the vehicle has a large technological dispersion of parameters, the computer is equipped with a mode for correcting the DUT indication table (tare) to improve the accuracy of fuel level readings. ATTENTION! Before starting the tare, make sure that the fuel level alarm is connected to the computer correctly and set the correct type of equipment combination. The calibration procedure can be performed at the request of the owner independently. To do this, you need to drain the fuel from the tank, leaving the minimum amount of fuel required for the fuel pump (for VAZ vehicles. 3 liters). this volume is then taken as the zero level.

3.10 Auxiliary computer operating modes 3.10.1 Correction of fuel consumption readings

Computer readings of fuel consumption parameters may differ from the actual values ​​for various reasons: diesel engine error in cars with a carburetor engine, a drop in pressure in the fuel rail, or clogged injectors in vehicles with an engine equipped with an engine control module (ECM). To correct the fuel consumption readings, enter the display mode "Current fuel consumption", press and hold the "START" button for 2 seconds until the indicator shows the correction factor. The nominal value of the correction factor is 100 (in percent). Changing the value of the coefficient is done using the "" or "-" keys, while a larger value of the coefficient corresponds to an increase in fuel consumption readings, and to a smaller one. decrease in fuel consumption readings. To exit correction mode, press the START button. The correction factor can be determined as follows. Generate fuel up to a specific fuel level value read by the computer. Fill the tank with the measured amount of fuel. e.g. 20 liters. Reset the computer's total fuel consumption by pressing and holding the START button for 4 seconds in the Total Fuel Economy display until you hear a two-tone tone. Generate all fuel that was filled to the original fuel level. Pay attention to the overall fuel consumption. e.g. 25 liters. Calculate the value of the correction factor: (20/25)? 100 = 80 Enter the calculated value of the correction factor in the computer. The correction factor range is from 50 to 255. Then reset the fuel consumption reading.

4 Installing the computer in the car

Signal names and computer plug pin numbers are shown in Table 1. Table 1

Gone are the days when the word computer was spoken aloud by a few people. Today, this device is available in almost every home and has become a regular device in automotive technology. He became an indispensable assistant for drivers, as he took over the functions of controlling the operation of most units of modern vehicles.

PURPOSE AND MAIN FUNCTIONS

Cars that are made in Russia are equipped with such a device. So, for example, a regular on-board computer, became the first-born in the family of VAZ cars. In simple terms, this is a car guide on wheels. The driver needs it in order to know what is happening both inside the car and outside.

WHY IT IS INSTALLED IN THE CAR

The first versions performed few functions, these were the following:

• Control over the availability of fuel on the vehicle and the distance that can be covered on it. This will help the driver make the right decision in time to refuel or stop driving;
• Monitors the working in the motor and helps to prevent its overheating.

The use of more expensive versions of computers allows you to diagnose individual components and assemblies of the machine.

They are endowed with the ability to decipher the fault codes that the controller issues, and this allows the driver to:

1. To be informed in a timely manner about the problems that have arisen in a particular system of the machine, and to respond correctly to this. Eliminating the problem in its "embryo" eliminates costly repairs;
2. Get savings from the operation of the car.

ABOUT ITS FUNCTIONS

On-board computers VAZ 2114 are endowed and perform the following main functions:

1. Display information about which indicators have instantaneous parameters;
2. Conclusion to the information panel of information of the current nature;
3. Route parameters are reported. Under them understand information about the mileage, average fuel consumption, travel time and other data;
4. Ability to read error codes and diagnose a car engine. This allows you to receive information about all the problems of the power unit without lengthy consultations with "specialists".

Some of the models have additions to the main functions, among which may be:

• Information about the timing of the next maintenance of the machine;
• Some adjustments to the main functions;
• Control over the period of insurance;
• Availability of organizer functions;
• The ability to set the parameters at which it will be possible to turn on the fan in the cooling system.

ON THE PRINCIPLES OF FUNCTIONING OF SUCH SYSTEMS

Carburetor cars VAZ 2109 were equipped with devices with the functions of routers. The installation of injection power plants VAZ 2114, VAZ 2115 and other models required the use of a completely different type of device. Most of its functional activities are dedicated to diagnosing and controlling the operation of almost all devices and vehicle systems.

The work of the BC VAZ 2114 is based and has the following principle of operation:

1. Receiving signals from sensors through the control unit, processing them and issuing messages to the display, as well as the possibility of making adjustments for other systems;
2. Handling signals from systems that are not controlled by the controller. In case of emergencies, the corresponding icon is displayed on the information board, and an audible signal is also given.

HOW SUCH DEVICES ARE USED: QUICK INSTRUCTIONS

For installed devices, instructions are attached for the standard on-board computer VAZ 2114. It informs and instructs car owners in detail about what needs to be done in a given situation. Let's talk about how to use the VAZ 2114 on-board computer. For its proper use, you must:

• These trip computers are highly sophisticated electronic devices capable of performing more than 500 different functions. All this requires the driver to carefully study this device. The user manual helps with this. It is good to study it with the information board on;
• When studying, the most attention should be paid to the icons and symbols of emergency commands.
• has buttons that control the operation of the VAZ 2114 BC. You need to study and remember the rules for working with them.

When choosing such devices, there are no special requirements for them. The selected model must support the 2114 programs. Today, the cost of the VAZ 2114 on-board computer can be from 1500 to 4000 rubles. You can find even more of these products in online stores.

It makes no sense to memorize all possible error codes displayed on the information board. They do not need to be recited by heart as in school. We live in the age of Internet technology, find the designation of these error codes, print it out and take it with you in the car. In the case when you see the symbols on the information board, you can quickly make the right decision. Continue driving or call for technical assistance. Unfortunately, there are times when the on-board computer erroneously issues a danger signal. The culprit in such cases may be some kind of sensor or the processor itself. No one is immune from emerging electronics malfunctions, but in most cases, the scoreboard signals reliable information.

The main possible error codes on this machine will be shown below.:

• 2 - the voltage of the on-board network is exceeded;
• 3 - problems with;
• 4 - a malfunction with a sensor that monitors the temperature regime of the motor;
• 5 - incorrect signal from the outdoor air temperature sensor;
• 6 - signal about an overheated motor;
• 7 - too low car lubrication system;
• 8 - problems with the braking system;
• 9 - battery undercharge.

You should respond to codes 4, 6 and 8, which must be eliminated and only then continue further movement. After elimination, the processor must be rebooted. Errors are reset by pressing and holding the daily run key.

WHAT TO DO WHEN BK STOP WORKING

It sometimes happens that the on-board computer does not work. What do experts advise to do in this case? First of all, you need to decide on. If it does not show “signs of life” at all, F3, which is installed in the power supply circuit of the VAZ 2114 processor. If its replacement did not “revive” its operation, check the connection connectors.

It makes no sense to describe the essence of the repair process of such a complex electronic product, since for this, in addition to having the necessary devices and tools, it is also necessary to have an education in the field of electronics.
