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.
- How to properly connect the on-board computer
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.
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.
Connecting an on-board computer to a VAZ 2109, VAZ 2115 with a connection connector
- We connect the K-line of the device using a long white wire to the M socket of the EURO 2 diagnostic connector, or to the EURO 3 connector in cell 7, while changing the terminal to 1.5 mm, which is included in the kit.
. ATTENTION. WITHOUT CONNECTION TO THE K-LINE THE DEVICE WILL NOT FUNCTION.
- The other end of the white wire, the 2.8 mm terminal, must be connected to the trip computer block of empty cell 2.
- The immobilizer is usually located near the ignition switch and wires from the immobilizer contact device are connected to it.
- If there is no immobilizer, then the immobilizer block will be empty. In this case, you need to install a jumper between pins 9 and 18 of the immobilizer connector.
We connect the external temperature sensor of the on-board computer
- The wire with the temperature sensor must be placed inside the front or rear bumper in a place to prevent moisture, dirt and warm air flows heated by the engine from getting on its surface
If the car already has an external temperature sensor installed, then it is recommended to place the BC temperature sensor inside the cabin (under the steering column) to measure the temperature inside the cabin.
After making all the connections, install the on-board computer , having first removed the plug in its normal place.
What capabilities should an on-board computer have?
In the following list we present the most important functions that every bookmaker should have:
- Do-it-yourself carburetor adjustment for VAZ 2107
- 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.

- Next, connect the BC pads to the standard connector of the trip computer.
- Connect the ground to the battery.
- Connect the temperature sensor.
To check the correct installation, when you turn on the ignition, the flow parameters will be displayed on the BC display. If not, make sure you have an immobilizer. If it is missing, you need to make a jumper between terminals 9 and 18 of the connector.
- On-board computer "CHEVY MATRIX". Instructions for use
To summarize the article, we note that the on-board computer on the VAZ-2115 is an excellent assistant that provides the driver with a large amount of information about the state of the main components of the car. Standard display panels, unfortunately, cannot boast of similar functionality. In this case, additional equipment helps a lot.
If you bought an on-board computer, but have never had experience working with automotive electrical systems, then it is better to entrust the installation and configuration of the BC to professionals - this will save you time and money.
Take into account the fact that every manufacturer of a high-quality device completes the product with all the necessary documentation, both for installation and configuration. When performing work, it is recommended to first look at the instructions. The article provides only general recommendations and a brief overview of the installation of two BCs on a VAZ-2115.
The on-board computer was installed on the VAZ-2115 relatively recently. The fact is that the first releases of this model were equipped with engines with a carburetor injection system. They did not have an electronic control unit that could read all the information about the operation of the internal combustion engine and other vehicle systems.
The on-board computer makes life much easier for the driver. Even a person who does not have extensive experience in installing special equipment can install it. Connecting the device will not cause any difficulties, nor will setting it up. When working, you can use the operating instructions that come with the kit.
On-board computer for VAZ 2113 instructions
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 (BC). What is a BC, what is its purpose and how to install an on-board computer on a VAZ 2115 - you will find the answers to these questions below.

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.
What computers can be installed on the VAZ-2115
On sale you can find a variety of models of on-board computers for domestic cars. The most important thing is that they work with electronic control units installed on VAZ cars. You should not skimp on trip computers, since expensive devices will be able to provide thorough diagnostics of the car and promptly warn you about malfunctions. They have a much longer service life and more functionality than cheap options.
On sale you can also find on-board computers that are installed instead of the instrument cluster. They are much more convenient, since all information about the operation of the vehicle systems is in front of the driver’s eyes.
Typical errors of on-board computers
To check the on-board computer on the VAZ-2115, you need to completely reset the daily mileage on the dashboard and turn off the ignition. After this, you need to press the button located near the windshield wiper switch. In this case, the display shows the firmware version and error codes, if any:
- If the voltage in the on-board network is too high, code “2” will appear.

Features of connecting the on-board computer
Before connecting the on-board computer to the VAZ-2115, you need to decide what functions you need. Be sure to compare the characteristics of the car and the capabilities of the on-board computer. If you don’t have any bells and whistles on your car, then there is no point in purchasing expensive and complex systems.
Decide on the installation location of the system display, as well as the central unit. It is best to install the device in the center console, if there is space. If it is not there, then mounting on the top of the dashboard is allowed. It won’t look very nice, so it’s better to allocate space in the center console, because ease of use of the device plays a big role.
But if you have a trip computer in the form of an instrument cluster, the location of its installation has already been determined. All connection wires must be carried out in special tubes; they will protect them from the negative influence of the external environment. The electrical wiring is connected only after the unit is installed on the vehicle.
CONNECTION
The connection diagram for the on-board computer on the VAZ 2114 is simple - it does not require special training or special qualifications. Therefore, you can connect the on-board computer to the VAZ 2114 with your own hands; detailed instructions are always attached to each device.
The connection principle is the same for all BCs, so let’s take a closer look at how to install an on-board computer on a VAZ 2114:
- De-energize the car (disconnect the battery terminals).
- We remove the standard plug from the instrument panel.
- We find the 9-pin connector.
- Remove the plug for the diagnostic connector.
- Remove the lower left side of the center console on the instrument panel.
- We take a piece of wire (about 1 m long) and connect it according to the following diagram. This wire in the diagram is designated as K-line white. That is, we connect terminal “7” (Euro-3) or terminal “M” (Euro-2) in the diagnostic connector with terminal “2” in the BC block with a wire.
