The onboard car computer or brains of the car is the most important element Management and monitoring the performance of all major vehicle nodes. BC is put on everything today modern cars. More information about the principle of work and varieties you can learn from this material.

Description of the side computer
What is the on-board computer in the car and what tasks does he perform? First, let's figure it out in some theoretical moments. BC is an electronic node that allows you to react and manage different processes in the work of different auto systems. That is, thanks to the BC, the driver will always be able to receive data on the operation of those or other components. What is a on-board computer, we figured out, now we will tell about its appointment.
What shows the on-board computer:
- the device demonstrates gasoline consumption at different motion modes;
- allows you to control the nozzles, as well as the vehicle ignition system;
- produces control of the transmission;
- can control various additional system of double-sided communication, for example, a rear view camera, etc.;
- allows you to determine the level of pressure motor fluid, antifreeze temperatures;
- regulates the voltage level in the electriable auto, controls the battery charge;
- if the vehicle is equipped with a climate control system, the BC manages it;
- one of the main options is the on-board computer for the car allows you to read error codes when necessary and show them on the display so that the driver can decipher them and find out where to look for a breakdown.
Principle of operation
The principle of operation of the automotive BC for carburetor engines or injection options is not particularly complex. The device is connected to the chain of controllers and regulators, reads the necessary data, after which processes the information received. For processing used special software. For example, if the BC according to the scheme receives data on fuel consumption, then the software will allow you to calculate the possible mileage on the remaining volume of gasoline.
All data are displayed on the screen installed in the vehicle cabin. The display itself can be digital, monochrome, color or four- or three-digit. As practice shows, a monochrome screen with a diagonal of 2 inches is enough to show the driver more than ten parameters. More modern variants of the BC are equipped with a liquid crystal screen of great accuracy.
Views
To date, several types of BC are distinguished:
- Universal version Such a device combines various options in itself gives a car owner the possibility not only to control the machine, but also to surf the Internet. The main purpose of such a device is to improve comfort for the car owner while driving. Usually, a universal on-board computer has a screen with a diagonal of 6-14 inches, a keyboard can be connected to newer models. It should be noted that, by its design, such BCs are very similar to ordinary computer PCs, but one of the features of the devices is the low degree of ignition from the car electrical system.
- Route. The route on-board computer allows you to determine the car driving parameters, while it is not necessary to connect it to the GPS to the satellite. Nevertheless, newer models in any case are equipped with GPS receivers. With this device, the driver will be able to determine the average speed of the machine, the consumption of fuel, the remaining distance to one or another point passed by kilometer, etc. In addition, depending on the model you install in your car, the device may have a combustion calculation function when emergency braking either rapid acceleration. Typically, the BC of this species is installed in the control shield.
- Manager and service BC. The purpose of such computers is to determine the breakdown of the main vehicle aggregates and the warning of the car owner. As a rule, such a BC is the component of the machine control system, but depending on the model, it may be an independent device in an extensive functionality. When checking the car, all error combinations are stored in the device's memory and will be there until the error is fixed, and the memory is reset (author of the video - AvtoGSM channel).
Setup BC
Make a on-board computer with your own hands - the task is difficult to fulfill at home. For the manufacture of the device you will need many different elements, including the display, chip, buttons, etc. Make a computer on your own without the experience of assembling such devices - it is impossible, so if you want the device to work correctly, it is better to order this procedure or buy a new BC.
If you decide to put on your car on-board computer for carburetor or injector enginesYou need to know how to configure the device correctly:
- If necessary, you can always activate the automatic setup option - then the device itself will take the desired configuration.
- If this option is not suitable, then go to the Settings menu - find the desired block and select it. It should be noted that in this case BC must be configured as the main device. One of the important roles in the setting determines the choice of mode, due to which the fuel costs will be fixed.
- Exposing this parameter, you have several options. One of them is a linear dependence, in this case the parameter will always depend on the control unit. If you decide to make the setting manually, then first you need to make a table on the consumption of fuel. Given this information, the BC will make calculations and output the corresponding parameters on the screen.
- In addition, it will be needed to determine the parameters that will begin to demonstrate the screen, depending on the model, their number may be different. Separately, select the parameter responsible for the activation temperature of the motor cooling fan.
Question price
The minimum cost of the BC from the company Multitroniks will be in the area of \u200b\u200b130 rubles. More expensive options can cost 7,500 rubles.
Sorry, currently there are no accessible surveys.
Video "How to make BC do it yourself"
Detailed scheme manufacturing instructions are presented on video (author - channel LibRal1973).
The computer is today an ordinary device with which a large number of people face at home and in large numbers vehicle. Specifies more specifically about car drivers, a computer, or as you are familiar with it, the on-board computer has become an indispensable to each of them, because only with it you can take control of the work of most aggregates.
Video about the work of an abnormal BC on VAZ-2114:
If we talk about cars produced in Russia, then the firstborn in the AvtoVAZ family, it was the VAZ-2114 that the on-board computer was mounted directly from the factory, which was able to notify the driver about all the events occurring, both beyond the way and in the cabin. Below in this article we will analyze in detail why the on-board computer is needed, and we will analyze a brief instruction to it.
Regular place in the instrument panel for on-board computer. The photo stands the plug.
The on-board computer of the first version mounted on the VAZ-2114, even had some functions, however, with ease watched the main parameters of the car:
- Fuel control And its calculation about the number of kilometers past - this feature allows the driver to make a decision about refueling in advance.
- Cooling fluid temperature control - This feature eliminates the overheating of the engine due to the timely user informing.
- Diagnostics separate nodes car - allows with maximum accuracy, and most importantly mobility, detect and eliminate the problems that have arisen.
Learn more about onboard computer functions
Onboard computers on VAZ-2114 are able to display the following information to their work screen:
- Instant performance of the engine, its turns, temperature, reality testimony and medium fuel consumption.
- Information about car run, time on the way.
- The ability to unmistakably read errors that have arisen in the system, which will allow you to immediately determine whether it is worth handling a malfunction in the car service or it is possible to correct everything with your own hands.
Modern onboard computers, by type Multitronics - C340. And his counterparts also know how:
- Control and inform the driver about the next technical inspection, car insurance, thereby the function of the organizer.
- Independently change the parameters of the fan, change the notifications of a sufficient mechanization warming temperature.
- It is possible to connect the parking sensors.
Note, in order to activate both other, extended functions in your BC, it may be necessary to firmware.
Principle of operation of the BC on VAZ-2114
Not standard onboard computer
The principle of operation of the on-board computer at first sight will seem primitive, however, in fact it is a technically complex device that simultaneously accepts, processes and, if necessary, notifies the presence of faults. The alert function takes place on the screen of a special icon and feeding a certain beep ..
Brief user manual
For all the on-board computers supplied on the VAZ-2114, there is its own user manual, and if it is not in the paper version, it can be easily located on the Internet, just to know the brand and model of the device. Despite the fact that the variants and models are many, the basic functionality in them in principle is similar.
The readings of the onboard computer.
- If you are just going to buy the BC, then you need to know whether specific model To the ECU of your car. As a rule, all the information already has the seller, and there should be no difficulties in this.
- It is better, first of all when familiarize yourself with the onboard computer to pay the time to the symbols of emergency commands and visual icons appearing on the display.
- Pay attention to the location of the buttons, and the rules for working with them, in order to quickly react to change the parameters in motion (on some BC models, the keys can be blocked at a certain vehicle speed - approx.).
Error codes for VAZ-2114
Since the ECU on all VAZ-2114 is similar or, at least, it is similar, then write in advance, and even more so remember them does not make any sense, the benefit of some models are capable not only to bring it on the screen, but also voice out all problems available in the car .
Most. the best option Definitions and definitions of faults will be a printed version of error codes on VAZ-2114. You can take them on the official sites of plants manufacturers of BC for VAZ-2114, and below we will imagine you, the most frequent errors that are found on the "fourteenth":
Codes Description 0102, 0103 Incorrect control indicator signal mass flow air. 0112, 0113 Inlet air temperature indicator signal is needed to replace the element. 0115 - 0118 Incorrect signal of temperature measurement element Co. - Need to replace the sensor. 0122, 0123 Interference or incorrect position control indicator signal throttle valve - It is advisable to replace the element. 0300 On-board computer (BC) revealed random or multiple pass ignition - In this case, the car can not start immediately. 0201 - 0204 A cliff in the nozzles control circuit is recorded. 0325 The on-board computer was recorded a cluster in the detonation device chain. 0327, 0328 The breakdown in the detonation sensor is necessary to replace the device. 0480 Failed the cooling fan - you need to replace the element. 0505 - 0507 There are failures in the functioning of the regulator idle movewhich affect the number of revolutions (lower or higher). If this code occurs, the regulators need to be replaced. 0615 - 0617 In the diagnostic process, clips or closures in the starter relay circuit were revealed. 230 This error code means the breakdown of the fuel pump relay - the device must be replaced as soon as possible. 1602 It is one of the most encountered codes in the diagnosis of BC for malfunction. Means the loss of tension on-board network on the electronic block Control. What to do if the BC stopped working
It happens that the BC stops working or the information that it should transmit and analyze is not transmitted. First of all, it is necessary to pay attention to the integrity of the electrical circuit. Namely fuse F3 responsible for its performance, then check the integrity of the wires that go to the diagnostic block, and ensuring its nutrition. You can connect the on-board computer to the VAZ-2114 system in this article.
Describing the process of repairing the ongoing computer it is pointless, because such devices are broken not often and little maintainable, therefore have technically complex mechanisms that require professional tools and skills.
On the passengers of the "Tenth Family" next to the display unit, a clock or computer is always installed. Now such computers are called "onboard computers" (BC). The computer display when the ignition is turned off shows the time, but this is not its only function! We list all the capabilities of the on-board computer on the VAZ-2112, and the instruction attached by the VAZ will help us in this. The instructions were copied tables that are important when setting up.
What kind of BC is we talking about? The answer is visible on the video.
The appearance of the facial panel is shown in the photo below. You need to remember the main keys: 1, 2, 3 and 5. All functions are divided into three groups. By pressing the 1 button, you can scroll through the functions of the first group. The same refers to other keys.
Stable BC for Lada-112 hatchback
Asks, why do you need a button 5? Being in any of the three groups, additional functions use this button. By the way, their number is two.
In each group, additional functions are different.
Example with scrolling
When the ignition is turned off, we see the clock on the display. Let's try to turn on the ignition and press the 1. The button itself can be pressed any number of times - the function switches cyclically. Their number is three.
Group of functions "Time"
If additional functions are needed, click on the button 5. We reviewed how to use a regular onboard computer on the VAZ-2112, but the instruction is suitable for any "dozens".
Operation of the BC in different modes
The above is said how to use the BC in the "time" mode. The group "Time" is the first, but there are two more - "fuel", "path". We give the table for them.
Group of Functions "Fuel"
The above is the table for the buttons 2 and 5.
Group of functions "Path"
Here are features included with buttons 3, 5.
Programming Instructions
We will change different settings. And try to turn on the alarm clock, change the brightness of the backlight, etc. Thus, the computer programming on the VAZ-2112 is referred to also.
Customize fuel level sensor
The tank first remains empty. Include the function "Fuel level" (2-5) and click the 4 button for longer than two seconds. Further perform steps:
- Click the button 3 for one second until the audio signal appears;
- Pour three liters of fuel into the tank. We are waiting for 10-20 seconds and repeat step 1;
- We repeat steps 1 and 2 until 39 liters hide.
We use speed exceeding alarm
Pressing the 3 button turn on the function " average speed" Click on the button 4. Further the buttons 5 and 6 set the required numbers. At the end, press the 4 button.
To turn off the option, use the high threshold value: 190 or 200 km / h.
Change the brightness of the backlight
We use the function 1-3 "time with stops". Press the button 4. The keys 5 and 6 are adjusted. Press the 4 button.
Alarm clock
Go to the "Alarm clock" option (additional feature in the "Clock" list). Press the button 4. Further, set the clock value (keys 5 and 6), click the button 4, set the value of minutes (keys 5 and 6). By pressing the button 4, the alarm clock is activated.
Alarm clock in the car - the thing you need
It remains to understand how to turn off the alarm clock. Do all the steps before setting the clock value, and then press the button 1. The alarm must be turned off!
How to set up calendar and watches
We reached the most difficult chapter. We immediately go to action:
For quick adjustment, perform step 1 and step 2. If then click on button 1, the readings of the clock are rounded: it was 13:57, and will be 14:00. Or otherwise: it was 14:05, and will be 14:00.
Our editorial 2112 with Gamma GF 212 BC. We are fully satisfied with them.
The most popular non-standard BC on the VAZ-2110 is the GAMMA GF 212 model.
Its cost about 2500 rubles . Installing a simple, you just need to connect to the K-line in diagnostic connector and bring the power wire.
There are such useful functions like blowing candles and so on. We can only recommend it among a large set of models presented in the market.
Very successfully turned up MK 2114-3857010 for 300 rubles 😉
Since I have long wanted to put the bortovik, but the prices for him, to put it mildly, bite - I took without thinking! 😊
The mincer features all the necessary basic functions.
The backlight of the display and signatures of the buttons is made in a traditional vasescale style - green-yellow. When you click on the MK buttons begins to make sounds ... Beeeee ... 😥
Since the old owner was not particularly talkative and did not really explain what kind of MK, I began to look for instructions for this miracle of technology. The funny thing is that there is no shelter. There are records about how someone bought and put the same MC and TP, but not instructions.
After I reset the MK after the old owner, more or less figured out the functionality:
MK is reset by parsing and pulling out the battery
When you first connect to meals, MK welcomes playing midi melodies - a la old Nokia-brick.))))
So, the buttons from the left-topoint:
1 COINT T.
1.1. Travel time without stops. Pasters the fight while the MK is turned on. You can reset long by pressing the start,
1.2. Total travel time for all trips
If you click on the start, you can set the backlight brightness - the plus and minus keys. Select a value from 0 to 100%
2. KM / H button
2.1. Middle speed on the trip
Pressing the start in this menu includes turning off the alert. (I have not understood what kind of alert)
2.2. Average speed for all time
If you click on the start in the menu 2.2, you can put a speed limit, for example, at 120 km of MK starts to delete
3. Button KM
3.1. Kilometer travel
3.2. How many kilometers can you drive until the next refueling
4. L. button

Namely fuse F3 responsible for its performance, then check the integrity of the wires that go to the diagnostic block, and ensuring its nutrition. You can connect the on-board computer to the VAZ-2114 system in this article.
Describing the process of repairing the ongoing computer it is pointless, because such devices are broken not often and little maintainable, therefore have technically complex mechanisms that require professional tools and skills.
Let's start with the fact that installing the on-board computer in a regular place on the VAZ 2114 and other Samar models is not so difficult. In the installation of the onboard computer, in principle, there is no harves with wires and nuts (unless, of course, no one has tried to you in the car and changed nothing). A knowledgeable person will set you a on-board computer for some 2 minutes, so you should not be afraid of your hands on your feet and forward with the song \u003d).
Why do you need an on-board computer?
In past articles, we have already said that such a on-board computer, for which it needs and what kinds they are. But I will allow myself to repeat so that you clearly realize all the advantages of the existence of a side computer, and there are probably no consumers, except that the waste of money for the purchase and that's it.
Take, for example, on-board computer Staff 115 × 24. Having this model in its presence, you can:
- set the radiator fan launch temperature; This feature is very useful, for example, in winter The time when you can control the temperature of the coolant, thereby monitor the temperature of the stove radiator.
- the function of drying and heating the candles before starting the engine is very helpful.
- the function of resetting the settings and controls of the ECU is needed to go to gasoline with a higher or low octane number (from 92 to 95 and vice versa), this feature is needed to reset the settings after a long trip with an increased engine load.
- the ability to read errors allows you to monitor the condition of the car, on time to change the non-working sensors, items.
Installation instructions onboard computer
In this article, we will consider the installation process of the Prestige side computer with the diagnostic and error reading feature.
To work, we will need:
- Screwdrivers
- on-board computer,
- the wire is 1M long.
Remove the plug on the central torpedo and we are looking for a 9-pin wire block in it. This shoe must be present on all cars of our model. It remains only to connect the block to the computer and everything, but we need to hold the line.
How to spend a line?
- We take our wire and install it in the second contact of our pad.
- The opposite end of the wire we throw under the instrument panel at the bottom to the diagnostic pad (for convenience you can unsubscribe the right sidebar).
- Cutting a wire to a diagnostic pad, connect it to the "M" jack if you have a shoe of Euro-2 or in the 7th socket, if you have a shoe of Euro-3 (very often occurs that the diagnostic shoe on Euro-3 is installed on the car up legs, consider it)
- Now connect the on-board computer, insert it into a regular place and check it.
For a more complete and visual presentation of work, a scheme is presented.
What if under the instrument panel there are no pads for onboard computer?
In this case, it remains only to assemble a new block: buy a 9-pin block and carry it to it according to the following scheme:
- fuel Consumption Signal (Green Wire)
- ignition (orange wire)
- + 12 volts (red / white wire) red wire with white stripe
- mass (black)
- speed \u200b\u200bsensor (brown wire)
- 6k-line (most often gray or black wire)
- mute (green / red wire) Green wire with a red stripe
- illumination (white wire, or can be taken from the dimensions button)
- fuel level sensor (pink)
Errors when connecting / operating onboard computer
Error: "There is no connection with the controller" or "cluster to-line".
This error indicates that the to-line is not connected or a contact occurred. Check the wire according to the scheme described above. Most likely flew contact with the diagnostic pad.
Error: Incorrect readings of the intangular temperature sensor.
If you have a temperature overboard -40, it suggests that the wire breakdown occurred to the temperature sensor, or there is no such sensor at all. If the temperature is for example -25, and on the street only -10, then you need to replace the sensor for a good.
By the way, it often happens that the on-board computer gives the danger signal absolutely unreasonable. The reason for this can be the processor of the on-board computer or some sensor working incorrectly. Remember, no one is insured against electronics errors. Nevertheless, in the overwhelming majority of cases, the on-board computer VAZ-2115 works right enough.
We present to your attention the most common error codes with their decoding:
- 2 - the on-board network voltage is exceeded;
- 3 - Fuel level sensor is incorrect;
- 4 - the sensor responsible for the temperature of the motor is faulty;
- 5 - Air temperature sensor Outside transmits warning signals;
- 6 - overheating of the motor;
- 7 - a very low pressure is observed in the car lubrication system;
- 8 - some problems have been discovered in the braking system;
- 9 - Low battery charge.
If the numbers 4, 6 or 8 appeared during traffic on the onboard computer of the car, it should be immediately stopped, eliminating the problem and only after that continue the movement. But after that you will need to restart the processor. You can reset the error, just holding a daily mileage key pressed for a few seconds.
What if on VAZ-2115 the on-board computer stopped working
Sometimes it happens that with the full condition of the car, the on-board computer completely refuses to work. How to do in this case?
Of course, you can try to eliminate the problem yourself. But still much better if this specialist will take place. It is he who can reliably determine the cause of the device malfunction.
But before you go to the service center, the first thing to be done is to check the F3 fuse, which he could simply turn the back. It is installed in the VAZ-2115 processor power supply chain. If, after replacing the fuse, the on-board computer does not further submit any signs of life, you can also check the connectors for connecting it. Repeat that if you are not an electrician, and do not really understand the electronics at all, this task should be entrusted to a professional.
Remember, any malfunction that the on-board computer shows, can be eliminated, as well as the breakdown of the side of the on-board computer. But, as they say, it is better to prevent the problem than later to decide. Therefore, each car should be kept in a normal state, to pass on time technical inspection And change spare parts that have failed. Among other things, it is better to prevent parts breakdown at all, but to replace them as wear. Only in this case, the car management will be safe from a technical point of view, and during the trip there will not arise abnormal situations associated with the improper operation of the car.
Feed your car - security guarantee both driver and passengers.
