On-board computer for VAZ 2115: review of the standard device, connection instructions, how to configure

Connecting an on-board computer to a VAZ 2109, VAZ 2115

Continuing the topic of installing on-board computers on VAZ cars, we suggest that owners of VAZ 2109 and VAZ 2115, which have an electronic injection system, install a standard computer on their car.
We suggest reading this article about all the advantages of this device and how to decide on its choice. Well, if you have already purchased a trip computer, then we offer a detailed guide on how to install it on a VAZ 2109. Where to install the trip computer for a VAZ 2109, VAZ 2115

As you know, VAZ 2109 and VAZ 2115 cars were equipped with a regular (high) panel and a Euro panel. Both options have space for installing an on-board computer . In the presented photos you can see these places; they are usually closed with a plug.

For example, we will use a Multitronics X140 (more details about the purpose and functions). The essence of connecting it to the VAZ 2109, VAZ 2115 comes down to the following.

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

1. 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.

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.

We recommend: VAZ 2110 signal does not work

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:

1. Power supply +12 V.
2. Power when the ignition is turned on to start the computer.
3. Power that appears when the side lights are turned on. This will cause the BC display to go dark at night.
4. Weight.
5. 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.
6. 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.

Connecting an on-board computer to a VAZ 2109, VAZ 2115 without a connection connector.

If your car does not have a standard connector for connecting the VAZ on-board computer , you should use the adapter block supplied with the device.

Connecting the on-board computer to the fuel level sensor (FLS)

To connect to the FLS for VAZ 2109, VAZ 2115 cars with a high panel, remove the visor of the instrument cluster and unscrew the screws securing the combination.

1. Stretch the green wire from terminal No. 8 of the BC connector adapter from the instrument kit to the instrument cluster.
2. Strip approximately 7 mm of the pink wire with a red stripe that goes to pin 11 of the white 13-terminal block of the instrument cluster.

Connection to K-line

1. Insert the male terminal of a single white long wire from the set of connecting wires into socket “M” of the EURO 2 diagnostic block, or, replacing the terminal with a narrower “1.5 mm pin” from the device kit, insert it into socket “7” of the EURO diagnostic block 3.
2. Insert the opposite end of the white wire, the “2.8 mm female” terminal, into contact No. 2 of the BC connector adapter.

And in conclusion, let us remind you that all work related to electrical wiring must be carried out with the battery disconnected.

Installation instructions for on-board computer

In this article we will look at the installation process of the Prestige on-board computer with diagnostic and error reading functions.

For work we will need:

1. Screwdrivers.
2. The computer itself.
3. Wire 1 m long.

We remove the plug on the central dashboard and look for a 9-pin wiring block in it. It should be on all Samara cars. All that remains is to connect the block to the computer and that’s it, but we need to draw a K-line.

How to draw a K-line?

Scheme of the K-line

1. We take our wire and install it in the second contact of our block.
2. We throw the opposite end under the instrument panel down to the diagnostic block.
3. Having stretched the cord, we connect it to the “M” socket if you have a Euro-2 socket, or to the 7th socket if you have a Euro-3 socket (it is very common that on Euro-3 it is installed on the car upside down, please note This)
4. Now we connect the computer, insert it into its normal place and check.

For a more complete and clear idea of ​​the work, a diagram is provided.

What to do if there is no pad for the computer under the instrument panel?

In this case, all that remains is to assemble a new block: buy a 9-pin one and run the wires to it according to the following diagram:

New block assembly diagram

• fuel consumption signal (green wire);
• ignition (orange);
• + 12 volts (red with white stripe);
• mass (black);
• speed sensor (brown);
• 6k line (most often gray or black);
• mute (green with red stripe);
• backlight (white wire, or can be taken from the size button);
• fuel level sensor (pink).

On-board computer on the VAZ-2115: instructions, connection

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.

Step-by-step installation of a computer on a VAZ-2115

The device will read information from the engine ECU.

1. Initially, turn off the power to the vehicle's on-board network - remove the terminals from the battery.
2. The car already has space for mounting the BC. All necessary wiring is already connected to this location.
3. 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.
4. At this point, the connection process can be considered complete.

Recommend: SWAP engine

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.

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:

1. Vehicle speed at the current time, average value, minimum or maximum.
2. Fluid temperature in cooling systems and braking.
3. The magnitude of the voltage in the on-board network.
4. Fuel consumption per 100 km. Moreover, you can display both the average value and the current, maximum, minimum.
5. 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 capabilities should an on-board computer have?

In the following list we present the most important functions that every bookmaker should have:

1. Remaining fuel in the tank.
2. Battery voltage.
3. Time.
4. Antifreeze temperature.
5. Temperature outside.

Additionally, the following options are available:

1. Average gasoline consumption per 100 kilometers.
2. Quality of engine oil.
3. 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.

We recommend: Central locking in a car - what is it, how it works, video

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:

1. Gasoline consumption while driving and parking.
2. 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.
3. 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.
4. 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.
5. 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.
6. Speed. Duplicates the traditional speedometer, but here the readings are more accurate.
7. 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.

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:

1. If the voltage in the on-board network is too high, code “2” will appear.
2. If the sensor indicating the fuel level is faulty, code “3” will be displayed.
3. If the coolant temperature sensor fails, code “4” will be displayed.
4. If there is a malfunction in the temperature sensor installed outside the car, an error code “5” will appear.
5. If the engine overheats, the on-board computer on the VAZ-2115 will display error “6”.
6. If the oil pressure drops below the minimum value, error “7” will appear.
7. Insufficient fluid level in the brake system - error code “8”.
8. When the battery charge is low, the code “9” will appear.

Brief instructions for use

The on-board computer in question is a structurally complex electronic design capable of performing about 500 options. The STATE variation is interfaced with the VAZ 2114 ECU, which ensures normal operation of the device. To use the computer correctly, you should study the purpose and functionality of the BC control buttons located on the dashboard.

It is not necessary to keep in mind the decoding of all the codes; you just need to print them out and take them with you. Important notices:

• 2
  – excessive voltage in the on-board network;
• 3
  – problems with the fuel indicator;
• 4
  – signals a violation of the temperature regime of the power unit;
• 6
  – indicates engine overheating;
• 7
  – critical decrease in pressure in the lubrication system;
• 8
  – violations in the brake unit;
• 9
  – battery discharge.

It happens that the BC issues codes incorrectly due to the failure of a sensor. However, you should not ignore checking the car, since, most often, the activation of errors indicates a malfunction. After fixing the problem, you should reset the processor. This procedure is performed by turning on and holding the daily mileage button.

What errors appear most often?

Most often errors appear with numbers “4”, “6”, “8”. The first appears when the engine is not warm enough. An error on the VAZ-2115 on-board computer with code “6” appears when driving in city mode, when the engine overheats, as well as when there is a breakdown in the cooling system. To reset these errors, you need to hold the button for a few seconds, which resets the car’s daily mileage.

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.

Why do you need an on-board computer?

In previous articles we have already talked about what an on-board computer is, what it is needed for and what types they come in. But let me repeat myself so that you clearly understand all the advantages of having an on-board computer, and there are probably no disadvantages, except perhaps spending money on the purchase and that’s all.

Let's take, for example, the on-board computer STATE 115×24. With this model in your possession, you can:

1. set the radiator fan start temperature; this function is very useful, for example, in winter, when you can control the temperature of the coolant, thereby monitoring the temperature of the heater radiator.
2. The function of drying and warming up the spark plugs before starting the engine is very useful.
3. The function of resetting settings and ECU adjustments is needed to switch to gasoline with a higher or lower octane number (from 92 to 95 and vice versa), and this function is also needed to reset settings after a long trip with increased load on the engine.
4. The ability to read errors allows you to monitor the condition of the car and change non-working sensors and elements in a timely manner.

Removing the on-board computer

If a faulty or outdated on-board computer is installed on a VAZ-2115, instructions for dismantling it are as follows:

1. Disconnect the negative terminal from the battery.
2. Remove the outer panel from the car radio.
3. Remove the car radio body by disconnecting the wires from it.
4. You need to put your hand into the hole to loosen the on-board computer housing.
5. Now you can remove the device and disconnect the wires from it.

Afterwards, you need to install a new on-board computer or a blank in the center console. The tape recorder can be connected and installed in its original place. A new computer requires virtually no setup.

The only thing that is needed is to calibrate the gas level sensor in the tank. To do this, completely empty the tank, set the trip computer to “0” and fill in 3 liters of fuel until it is full. When finished, the on-board computer will save the data and go into standby mode. Here's how to connect an on-board computer to a VAZ-2115 with your own hands. Similar work is carried out when installing devices on other injection vehicles.

PURPOSE OF THE ON-BOARD COMPUTER

An on-board computer on a car is an electronic computer device designed to monitor the status of various components of the car and transmit information to the car owner. Depending on the technical equipment, on-board computers (BCs) can vary in complexity, and accordingly, the price of the device can vary significantly.

The VAZ 2114 car is equipped with BC 2114-3857010 as standard from the factory. The device is mounted on the panel to the right of the instrument cluster at the same level with it. On those VAZ models that are not equipped with such a device, there is a plug in the standard place on the instrument panel and there must be a 9-pin connector for connecting the device.

In the “native” BC 2114, you can view the following parameters on the display:

• Current time and date;
• Travel time excluding stops;
• Travel time, including stops;
• Gasoline consumption at the current time;
• Average and total gasoline consumption per trip;
• Mileage on the remaining gasoline in the tank;
• Signal when there is a minimum amount of fuel left in the gas tank;
• Total level of remaining fuel;
• Travel distance;
• Average speed during the trip;
• Vehicle network voltage;
• Signal when the mains voltage is below the permissible level.

The “Lux” package is equipped with an AMK-211501 on-board (or route) computer, which has added firmware that allows you to diagnose the electronic engine control system (ECM). But many owners of VAZ models 2113, 2114, 2115 are not satisfied with the standard equipment with its limited functionality, and they strive to install a more advanced BC with a larger set of controlled parameters. They can be understood - now there are many different models from different manufacturers.

The smallest BC State X-1M is made in the form of buttons.

BC State X-1M

It is mounted above the standard location of the trip computer instead of push-button plugs. Among the interesting additional functions of the device are:

• “Plasmer” – warming up the spark plugs before starting the engine;
• “Tropic” – the ability to change the temperature at which the fan turns on and thereby prevent engine overheating in hot weather.

In total, the device has 30 functions, and the BC costs about 1000 rubles. More expensive trip computers are installed in a standard place and are more functional. On the display of the Orion BK-46 model you can see up to 7 controlled parameters simultaneously, and when the battery is disconnected, all data is saved in memory in the device. The issue price is about 2500-2800 rubles.

One of the most advanced BC models for the VAZ 2114 is the “Gamma GF 415T”. Here you can see interesting features such as:

• Displaying three multi-displays on the screen at once;
• Non-volatile quartz watches;
• Informing about the need to change oils, filters, spark plugs, etc.

There are a lot of controlled parameters, the cost of a bookmaker is in the range of 4000-4600 rubles. Many systems are equipped with audible alerts, and these computers are very easy to use.

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.

Errors when connecting/operating the on-board computer

Error: “No connection with the controller” or “break in the K-line.”

This error indicates that the K-line is not connected or a contact break has occurred. Check the wire according to the diagram described above. Most likely the contact has come off the diagnostic block.

Error: Incorrect readings of the sea temperature sensor.

If your temperature outside is -40, then this indicates that the wire to the temperature sensor has broken, or there is no such sensor at all. If the temperature is, for example, -25, but it’s only -10 outside, then you need to replace the sensor with a working one.
