Why is the VAZ 2114 on-board control system display unit needed and how to troubleshoot problems?
A computer is an everyday device today that a large number of people encounter both at home and in a large number of vehicles.
Speaking more specifically about car drivers, a computer, or as it is more commonly called, an on-board computer, has become indispensable for each of them, because only with its help can one take control of the operation of most units. Video about the work of a non-standard BC on a VAZ-2114:
If we talk about cars produced in Russia, then the first-born in the AvtoVAZ family was the VAZ-2114, on which an on-board computer was installed directly from the factory, which was able to notify the driver about all the events taking place, both overboard and inside the car. Below in this article we will look in detail at what an on-board computer is needed for, and we will also look at brief instructions for it.
Restoring the work of the BSK
The essence of the recording is clear from the title.
The BSK has not worked since I bought the car; in principle, I didn’t really need it, but if it’s in the car, then it should work. The probability of the block itself breaking seems to me to be 1 in 1000. In principle, there is nothing to break there. I was sure that either the wire block was not connected to it at all, or there was no 12V coming to the unit. After disassembling the panel and freezing the block, I got to the block. I was so carried away by the process that I didn’t take any photos of the disassembled panel) I found the pinout on the Internet and rang it with a multimeter. Pin 9 (diagram below) does not receive positive from the ignition switch. That's what I thought) There was no desire to change the lock or do anything with the old one, and I decided to go a different route. I simply connected contacts 13 and 9 with a wire in the block. I didn’t take a photo of the block itself, and I couldn’t find it on the Internet either, so I showed it on the block itself.
in reality it looks like this. the quality of the photos sucked because I only had a phone with no autofocus on hand
Now everything works properly, the squeaker just infuriates) it was better without it)

VAZ 2114 devices do not work
If on a VAZ-2114 car on the instrument panel none of the indicators installed on it work (speedometer, odometer, tachometer, fuel level and coolant temperature indicators), then the first thing the driver will have to do is check the integrity of fuse F3, which is located in the mounting block. If it has burned out, then before replacing it, you need to find the reason why it burned out, otherwise the newly installed new fuse will have the same fate as the previous one. Most often, fuses burn as a result of a short circuit.
How to take additional measurements
If the electronics give values that seem implausible or, due to a breakdown, simply do not show them, there is an old and time-tested other way to measure fuel consumption. To do this, you just need to fill the tank, which is called “to capacity.” In this way, both gasoline and diesel vehicles are checked.
Reset the daily trip meter to zero. You drive on a full tank until the control indicator starts flashing, indicating the fuel level. Repeat the operation again, writing down how much fuel you filled. Having received data on the kilometers traveled and the volume of fuel filled, you can calculate the average consumption.
Why does the VAZ 2114 instrument panel not work? A massive problem in our auto industry
The search for possible reasons why the VAZ 2114 instrument panel does not work periodically worries one or another owner of cars of this model. It’s clear that if you don’t see a single parameter on the dashboard, you can only drive, as they say, by touch. True, there are certain specialists who still managed to somehow crawl to the base without all the evidence, but somehow I don’t want to follow their example.
And is it necessary to create additional troubles and the risk of accidents on the road? So the majority of those to whom this incident happened still get to work (or wherever they were going) by public transport in order to return to solving the problem in the evening on their own or with the help of a familiar mechanic.
Why does the VAZ 2114 instrument panel not work? Offhand, we can name several reasons. However, they may not exhaust the entire list, since the individual characteristics of the car may appear. We will try to talk about this and many other equally interesting things in our article today.
Differences between bookmaker and control panel
Experienced drivers know that the speedometer simply converts engine revolutions into speed, and as soon as you change the wheels to a larger diameter, the speed will increase, although the indicator will work the “old-fashioned way.” In order not to get into trouble at the next traffic police post, you cannot do without a BC. But much remains not taken into account by simple fixators, and on a long journey such factors as actual and average fuel consumption, information about the mileage already covered, the amount of fuel used, etc. will be quite appropriate. These parameters of the VAZ 2114 can be calculated, but is there any time for the driver, who is primarily obliged to watch the road and not do calculations.
The “smart” car 2114 will itself monitor that the car does not overheat in the heat, and the most advanced on-board computers will even alert you to the danger of ice formation in cold weather. The computer will also report the voltage inside the engine system. With such an assistant, the trip will be much safer, over short or long distances. The main thing is not to ignore your computer's warning signals.
Errors when connecting BC to VAZ 2114
Just a few years ago, a car's electronic system was considered a luxury innovation, but recently many cars are equipped with this element.
Most motorists would like to have a car filled with all the technical innovations. But unfortunately, not all cars of the VAZ family are equipped with an electronic system. Installing an on-board computer on a VAZ 2114 yourself should not cause any difficulties.
The functionality of the electronics is quite extensive; it has a large number of various programs aimed at improving the performance of the car and monitoring its technical condition. This system determines with the highest accuracy many machine operating parameters, for example: speed limit, brake fluid temperature, voltage level inside the machine system and much more. Moreover, the indicators of the on-board computer are several times more accurate than the indicators of standard instruments. The functionality of the electronic on-board system is very diverse.
In addition to determining the accuracy of indicators in the operation of the machine, on-board electronics do an excellent job of diagnosing all vehicle systems and identifying fault codes. There should be no difficulties in deciphering the codes, because... The on-board computer instructions contain all the necessary transcripts.
The advantages of electronics are quite noticeable; it is possible, without visiting a service center, to independently identify all problems that arose during operation and eliminate them in a timely manner. An important point is that the system helps to avoid quite serious consequences of a malfunction thanks to timely diagnosis.
Another advantage of this system is the equipment with sound alarm and light alarm. This type of alarm also informs the car owner about problems that have arisen in the car’s network, or informs about engine overheating. Installing an on-board computer on a VAZ 2114
Which on-board computer to install on a VAZ 2114
The main point that you need to follow when choosing an on-board computer for a VAZ 2114 is support for the VAZ2114 ECU program. In addition, there is no need to save money; more expensive electronics will be able to check the condition of the machine and promptly signal a malfunction. Errors on-board computer VAZ 2114
To check the computer, you need to reset the mileage for the day on the dashboard and turn on the ignition at the same time. Then, by pressing the button on the windshield wiper lever, you will see on the display the computer firmware version with error codes, if any.
Checking the indication
There are 5 indication modes:
- off – when the key is not in the ignition switch;
- standby mode - the BSK VAZ 2114 goes into it when the key is inserted into the ignition, but remains in the “Off” position; if you open the door, an error about a forgotten key will be displayed. You must close the door or remove the key to stop the horn;
- test - turns on when the ignition key is turned to the “Ignition” position. A sound signal and the turning on of all the system lights indicate that the device is working properly. Afterwards, all systems are tested, while the sensors are turned off;
- preliminary test - after testing is completed, the VAZ 2114 display unit, if there are malfunctions, the diode responsible for a certain parameter begins to blink for 8 seconds, after which it lights up evenly until the key is returned to the “Off” position. The blinking of the indicator is accompanied by a rhythmic sound signal;
- test with the engine running - this mode for BSK 2114 is the final stage of control. Monitoring of sensor parameters goes into sleep mode. It only carries out periodic additional monitoring of the vehicle’s performance. All malfunctions that occur in this mode are remembered until the end of the trip and the lights glow steadily.
In case of traffic problems, notification is carried out according to the preliminary test algorithm from 8c. blinking
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:

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.
Basic information
The functionality of this device provides a lot of possibilities. Using the on-board computer on the VAZ-2115, you can determine almost all engine operating parameters. What allows you to control the device:
- Vehicle speed at the current time, average value, minimum or maximum.
- Fluid temperature in cooling systems and braking.
- The magnitude of the voltage in the on-board network.
- Fuel consumption per 100 km. Moreover, you can display both the average value and the current, maximum, minimum.
- Gasoline level in the fuel tank.
These are just a few of the parameters that electronics can monitor. Using the on-board computer on the VAZ-2115, you can also check the status of all sensors of the injection injection system. Moreover, the operating instructions for the device must contain information about which error code corresponds to the malfunction of a particular sensor.
By installing such a trip computer on your car, you can get rid of visits to auto repair shops the first time the CHECK ENGINE light comes on. Every time you turn on the ignition, you see before your eyes all the errors that are present in the car’s systems. If necessary, you can erase them.
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:

Operating instructions for the VAZ-2115 on-board computer
Cars manufactured on the territory of 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:

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.
Private situations
General signs do not always indicate specific breakdowns. There may be exceptions.
If individual devices refuse to work, it is quite possible that this is their personal problem. You'll have to parse the specific pointer. It may have a cracked gear that needs to be replaced.
Also, why doesn’t the instrument panel of the VAZ 2114 work? If the fuel gauge and tachometer are capricious (either they function, or they don’t react at all), the contacts and the mounting block are normal - you need to do a small check.
Reset is pressed and held, and the ignition is turned on at the same time. Raised arrows indicate the need for further searches. Lifeless - that microcracks have appeared in the shield itself. You will have to remove it and examine all soldering and traces under a magnifying glass. In principle, these are all the main options. If calling all the listed components and parts did not lead to the revival of the instrument panel, your case is individual, and you will have to determine the situation in the company of an experienced auto mechanic.

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.

Five days ago I finished what I had been doing for a month... I was soaring that the BC screen was glowing green when the inscriptions were glowing red. Not in order! I was looking for how to do it, there is no information, only rare perverts do this. But one day I found an article that explained everything very clearly! A question came into my head: “Overexposure on the board! Why didn’t I think of it?!” I began to disassemble the BC and took it apart. To begin with, I soldered 3mm matte LEDs to SMD.
