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:
- Controlling the amount of fuel poured into the tank.
- An approximate calculation of the distance that can be driven with the remaining fuel in the tank.
- 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.

Diagnostics using special equipment
1. Diagnostic connector
2. Connecting a wire with an adapter to the diagnostic socket
3. Connecting the wire to the computer
4. Running software for testing
The diagnostic process using special equipment consists of checking the car using a laptop. To connect to the diagnostic connector you will need a cable with an adapter. Using this cable, we connect the computer to the connector via USB output. For testing you will also need software; the power of the computer used is not important. There are many versions of different testing programs on the Internet.
Diagnostics is performed as follows:
- It is recommended to inspect the vehicle before starting the inspection. Check the volume of consumables - engine oil, brake fluid, coolant.
- Find the diagnostic connector and connect your laptop to it. If you have a special scanner, then that's even better. But since finding a scanner is not so easy, and buying one is not cheap, you can use a laptop. Before testing can begin, the ignition must be activated. There is no need to start the power unit.
- After connection, the testing utility starts. The software interface may vary. When you launch the software, graphs or a list of parameters with numbers may appear. This information will allow you to draw conclusions about the operation of the power unit.
- The scan starts. Fault codes will appear on the laptop screen. To decrypt, use the information provided in this article. We could not describe all the codes, but we deciphered those that occur most often. Usually, when downloading a program to a computer, users are provided with a separate file describing the faults.
- After decryption, the problem is repaired.

ABOUT THE PRINCIPLES OF OPERATION OF SUCH SYSTEMS
Carburetor VAZ 2109 cars were equipped with devices with router functions. 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 devoted to diagnosing and controlling the operation of almost all devices and systems of vehicles.
The operation of the VAZ 2114 BC is based on and has the following operating principle:
- Receiving signals from sensors through the control unit, processing them and issuing messages on the display, as well as the ability to make adjustments for other systems;
- Processing signals from systems that are not controlled by the controller. In the event of an emergency, the corresponding icon is displayed on the information board, and a sound signal is also given.
Installing a computer on a car
The names of the signals and numbers of contacts of the computer plug are given in Table 1.
A description of the computer contacts is given in Table 2
| Fuel consumption signal input . A rectangular pulse signal with a frequency proportional to fuel consumption. The signal source is contact “2” of the DRT or contact “54” of the ECU (fuel injection controller) type M1.5.4 (January-5.1) or contact “32” of the ECU of type MP7.0. |
| Line "K" diagnostics . The contact is connected to contact “ M ” of the diagnostic block for VAZ vehicles or contact “ 11 ” of the diagnostic block for GAZ vehicles. Through this line, the computer exchanges information with the ECU. Data is transmitted in the form of a series of pulses with an amplitude from a low level (0 V) to the on-board network voltage. The line passes through contacts “ 9 ” and “ 18 ” of the control unit of the automobile anti-theft system (hereinafter referred to as APS), which must be closed in its absence or when the APS is not activated. The “K-line” signal from the car parking device is connected to this contact. |
| Voltage signal input from ignition switch . The signal from the ignition switch does not provide power to the computer; it informs the computer that the ignition is on. Used to measure on-board network voltage. |
| DVT signal input . The computer sends a +5 V voltage through this circuit through an internal resistor to the DVT, which is a thermistor with the second terminal connected to ground. The sensor changes resistance depending on temperature. |
| Non-switchable voltage input . Constant power supply to the computer from the vehicle's on-board network. The voltage comes through the fuse. |
| Voltage input of the car instrument scale illumination circuit . The signal controls the brightness of the computer indicator backlight. |
| Frame . The contact is connected to the car body (ground). The voltage at the contact should be close to zero. |
| Fuel level input signal . The contact is connected in parallel to the vehicle's FLS signal circuit. Connection location: car instrument cluster connector. The signal voltage value is used to calculate the fuel level depending on the type of instrument cluster and the installed fuel level table. |
| DSA signal input . A rectangular pulse signal with a frequency proportional to the speed of the vehicle. The signal comes from contact “2” of the vehicle’s DSA or from the output of the instrument cluster (speed signal for the computer) or from contact “9” of an ECU type M1.5.4, January-5.1, MP7.0. |
How to choose a quality bookmaker
The main rule when choosing a computer for a car is that the device must support collaboration with the computer. And secondly, you need to be guided by personal preferences. You must clearly understand for yourself what functionality the device should have.
The on-board computer from Multitronics fits perfectly into the VAZ 2114 car. Among the devices of this company, you can choose the best option for your car.
If BC is required to represent a limited number of parameters, economic models should be preferred.
Today there are a huge number of automotive gadgets for various purposes. The on-board computer can be universal - for monitoring car systems and accessing the Internet. It can also be highly specialized. Particularly popular today are route BCs, which allow you to build a route using an interactive LCD display, download various maps of the area from the Internet and perform a number of other useful actions.
The price range is quite wide - you can buy a device for 1000 rubles, or you can buy it for 5000 rubles. Of course, more expensive models have enormous capabilities. They can start the engine to warm up at a specific time, alert you to low tire pressure, and turn on the GPS navigation system.
If these functions are not critical for you, then you should choose an on-board computer from the budget segment and not overpay for functions that will never be useful.
Basic error codes
A good BC not only displays the information the driver needs, but also deciphers error codes. If any of the vehicle systems fails, the corresponding error code will appear on the computer display. To decipher it and understand what the problem is, you need to refer to the documentation, which contains the entire necessary list.
To find out if there are any errors in the system, proceed as follows: reset your mileage for one day and get in touch.
Fault code 3 indicates a faulty fuel level sensor.
Code 6 indicates engine overheating, and error 7 can be interpreted as low oil pressure in the system.
The instructions for the VAZ 2114 on-board computer contain the entire list, so in case of an error, you must first refer to it.
