The dashboard of the VAZ-2115 has a pre-designed space for the subsequent installation of an on-board computer. In this case, if you need to install a control device in a car, then there is no need to change the design of the torpedo, but rather use a standard socket.
The on-board computer provides comprehensive information to the driver about the following indicators:
- Vehicle movement mode.
- Gasoline consumption.
- The state of the car's electrical network and so on.
In addition to information capabilities, such a device is capable of diagnosing the state of the internal combustion engine control system. Certain types of on-board vehicles can be installed on cars with carburetors. However, for everything to work, you will need to additionally install a number of sensors.
In the modification of the VAZ-2113, a computer is installed that interacts with the controller of the internal combustion engine control system. Its task is to process all incoming information and display the main indicators on the screen in an understandable form.
Automotive stores today sell a wide variety of such devices, which differ in their functionality and location in the car.
All functions of the device in question are divided into two parts:
- Informational.
- Diagnostic.
To enable the required operating mode, use seven buttons on the device panel:
- Pressing this button tells the computer that the ride has begun. The same element resets the accumulated information in memory.
- + and – are designed to adjust the values of various characteristics when the device is in setup mode, as well as to study information about the state of specific components of the car.
- In addition to display functions, the on-board computer can produce sound signals when the actual parameter values exceed the maximum permissible standards. This is a kind of emergency signal.
These are not all the functions of the device in question, but only the main capabilities. Next, we will look at the process of installing a computer in a car.
General principles for connecting a computer
Basically, an on-board computer is an inexpensive device, but quite useful. We have already mentioned this. Now we will look at the process of installing the BC into the car.
If you have not purchased a device yet and are wondering what to choose, pay attention to Multitronics and the State. We will look at the connection process using the Multitronics X140 as an example. Note that there is now a similar modification on sale, which is equipped with a color display.
Buy an on-board computer in online stores. In car markets, the cost of such products is often greatly inflated.
The following wires need to be connected to any on-board computer:
- Power supply +12 V.
- Power when the ignition is turned on to start the computer.
- Power that appears when the side lights are turned on. This will cause the BC display to go dark at night.
- Weight.
- Signal from the fuel level sensor. Some device modifications allow you not to connect this wire. Multitronics X140 calculates the remaining gasoline based on instantaneous consumption.
- Connect the diagnostic line from the K-Line controller.
For the first four points, a 4-pin block is used, specifically designed for connecting a BC. Accordingly, it is enough to connect it with the adapters that come with the computer. If this is not possible, then the first point is connected from the cigarette lighter, the second - from the ignition switch, 3 - from the cigarette lighter backlight. The ground is connected from the body of the same cigarette lighter.
It is very important that before any actions with electrical wiring you need to reset the negative terminal on the battery. This will protect you and your car from short circuits and other troubles. The signal from the fuel remaining sensor is taken from the gasoline level indicator. Its location can be found in accordance with the wiring diagram of the machine.
The diagnostic line (K-Line) is connected to the EURO-3 block in the seventh socket.
How to withdraw BC
Let's not prevaricate, but rightly note that the quality and functionality of the standard on-board computer offered for the VAZ 2114 leaves much to be desired.
Therefore, the decision to install an alternative with expanded functionality and capabilities on the part of car owners is quite fair.
Wiring
Having decided all these nuances and selected a new on-board computer, you can safely begin dismantling the old BC.
Disconnect the negative terminal from the battery installed in the engine compartment of your car. This is necessary in order to protect yourself from electric shocks, as well as to avoid damage to all wiring. Remove the radio that is on your console. Remove the outer panel from the audio system. Now you can fully remove the entire cassette cassette
All wires connected to it must be detached. A hole will open in front of you, where you stick your hand and carefully open the computer unit mount. Take out your outdated or unusable on-board vehicle, having first disconnected all the wires connected to it. If you are not going to install a new BC, then the dismantled wiring must be connected. Otherwise, you will have problems while operating the car. A number of devices are connected to your on-board computer
Therefore, they will also have to be disabled. Do this carefully and gradually. No sudden movements. Otherwise you will have to change the wiring. If a new bookmaker claims to take the place of the old one, start connecting at this stage. Insert the radio into place, assemble all the components in their places, observing the reverse dismantling sequence.
The work is not difficult, but it will take some time to complete it.

How to install and configure the on-board computer on a VAZ 2115?
The operation of a car engine, as is known, depends on the performance and condition of many mechanisms and sensors. And to ensure their synchronous operation, which allows the engine to operate in the most optimal mode, monitor the on-board computer (BK). What is a BC, what is its purpose and how to install an on-board computer on a VAZ 2115. The answers to these questions will be found below.
Step-by-step installation of a computer on a VAZ-2115
The device will read information from the engine ECU.
- Initially, turn off the power to the vehicle's on-board network - remove the terminals from the battery.
- The car already has space for mounting the BC. All necessary wiring is already connected to this location.
- After removing the plug, you will see the wiring harness and plug - connect everything to the appropriate sockets on the computer and secure the panel.
- At this point, the connection process can be considered complete.
It is recommended to check the correct operation of the device at the stage of purchasing the bookmaker. The seller must do all diagnostic processes free of charge - it is his responsibility to sell you a quality product.

Brief instructions for installing and connecting the on-board computer:
- First of all, you need to turn off the car's electrical network, this is necessary because otherwise a short circuit may occur during the connection. To turn off power, disconnect the battery.
- First remove the car radio and then. center console. For the console, you will see a location to install the BC, this is provided by the manufacturer. All necessary wiring has been brought to this location.
- Then remove the plug-in after that, you will be able to see the wiring harness as well as the connector. You need to connect all the required plugs to the BC. In particular, we are talking about the power cable from the on-board network, the power source when the ignition is activated before the start of BC, the power from the general lighting, the ground, as well as the fuel level controller. You must also connect the diagnostic line, if you do not do this, the device will not be able to diagnose errors and display them on the display. In addition, after connection, the device must be securely fastened. This is also important because if the mounting quality is poor, the BC will be subject to vibration.
- Reinstall the center console using the radio. This completes the installation procedure. Now you only need to configure the BC according to the operating instructions and test it.
What capabilities should an on-board computer have?
In the following list we present the most important functions that every bookmaker should have:
- Remaining fuel in the tank.
- Battery voltage.
- Time.
- Antifreeze temperature.
- Temperature outside.
Additionally, the following options are available:
- Average gasoline consumption per 100 kilometers.
- Quality of engine oil.
- Worn spark plugs.
The Multitronics X140 diagnostic computer, in addition to the above capabilities, has voice guidance. This function warns the driver in time about various changes in the car. For example, when fuel runs out, the system instantly notifies you if there is less than 5 liters of gasoline left in the tank. In cold weather, the computer reminds you that there may be ice on the road.
According to reviews from experienced drivers, some are very annoyed by the display backlight when driving in the evening/at night. But after some time of use, everyone gets used to this device, and driving without it becomes no longer so convenient.
Diagnostic capabilities of Multitronics x140:
- Gasoline consumption while driving and parking.
- Antifreeze temperature. This indicator allows you to monitor the proper operation of the temperature sensor. It also determines the process of warming up the internal combustion engine.
- The voltage of the car's electrical network in volts. Thanks to this parameter, you can timely track various generator malfunctions, belt slippage and other breakdowns in the on-board system.
- The tachometer displays the crankshaft speed when the engine is idling. If the deviations are significant, this indicates that there is a malfunction in the vehicle’s fuel system.
- Throttle position. Using this characteristic, you can monitor the health of the sensor (TPS). In addition, the driver knows about the depth of travel of the gas pedal. When the engine is turned off, but the ignition is on, when you press the pedal, the indicators should smoothly change from 0 to 100 percent.
- Speed. Duplicates the traditional speedometer, but here the readings are more accurate.
- Malfunctions of the injection system.
Thus, the on-board computer in question receives all diagnostic fault codes and interprets them on its display in a form understandable to the driver. BC allows you to reset accumulated information.
How does a bookmaker differ from a control panel?
Many car owners are sure that there is no need for an on-board computer; all data is displayed on the dashboard, and that’s enough.
Universal model
Simple clamps do not cope with their tasks as well as BC is capable of it. In theory, it is possible to calculate only from the dashboard the amount of fuel used, current and average fuel consumption, the number of kilometers traveled, and so on. But why sit behind the wheel and calculate something, be distracted, if you can just get an on-board vehicle and look at its screen, receiving the necessary information based on changing parameters.
So there is a significant difference between the BC and the dashboard.
Hazard warning light - practical or not
Emergency notifications play a fairly important role in modern car computers. In particular, the driver can be promptly notified of the following:
- Motor overheating when the temperature exceeds 115 degrees.
- Changes in the vehicle's electrical network. The signal appears when the voltage drops or exceeds permissible limits.
- Exceeding the speed limit at a preset threshold.
Also, on-board computers inform the driver about the need for maintenance. During the process of setting up the computer, indicators are indicated at which it is necessary to change the oil, air filter, and so on.

Briefly about the main parameters of the computer:
- The device shows the speed at which the car is moving. You can also use it to determine the remaining fuel in the tank and the driving time at a certain interval.
- BC shows the number of engine revolutions.
- Thanks to this device you can always find out the engine temperature.
- The device determines fuel consumption in a certain area, kilometers traveled and number of kilometers.
- In addition, the device allows you to determine the voltage level in the vehicle's on-board network.
- Throttle position.
- As stated above, with the help of the BC, personnel can identify possible faults present in the power supply.
- Another parameter determined by the computer is the cyclicity of air flow circulation.
- Average car speed.
- Information about the time when it will be needed.
- Information about the need to change certain parameters.
- Based on the model and the data stored in its memory, the device can calculate the next time the car owner will pay for insurance.
- Various information from the organizer.
Dismantling
The device is dismantled according to a similar principle:
- First, to de-energize the on-board
network, you must disconnect the terminals from the battery. - Then the center console is dismantled along with the audio system.
- Through the displayed window, you must disconnect the power cords from the computer.
- The unit is then removed and the center console containing the car stereo is reinstalled.
In terms of specific settings, this procedure will vary depending on the type and model of BC. The modern automotive market offers consumers different types of BK, differing in price and functionality, as well as by manufacturer. Because of this and the setting principle. To properly set up your computer, you must carefully study the operating instructions; it will indicate all the main points of this process.
