The time passed when the computer's word out loud pronounced the units of people. Today, this device is available in almost every home and has become a regular device in automotive techniques. He became an indispensable assistant for drivers, as it took on the performance of the functions on the work of the majority of the aggregates of modern vehicles.

Appointment and main functions

Cars that are manufactured in Russia are equipped with such a device. So, for example, a regular on-board computer, became the firstborn in the family of Vazovsky cars. If we put up with simple words, then this is a car handbook on wheels. He needs a driver in order to know about what is happening both inside the car and outside.

Why install it in the car

The first versions performed some functions, these were:

• Control over the presence of a fuel reserve on a vehicle and a distance that can be overcome on it. This will help the driver in time to take the right decision to refuel or terminate the movement;
• Watching the working engine and contributes to preventing it overheating.

Use more expensive versions of computers, allow you to diagnose individual nodes and machine units.

They are endowed with the ability to decrypt the fault codes that the controller displays, and this allows the driver:

1. Be timely informed about the problems that have arisen in a particular system of the machine, and react to it correctly. Elimination of the problem in its "bud", eliminates expensive repairs;
2. Get savings from the operation of the car.

About his functions

Side computers VAZ 2114 are endowed and performing such basic functions:

1. Reflect information about which indicators have instantaneous parameters;
2. Output to the information panel of the current information;
3. The route parameters are reported. Under them understand the information about the mileage, average fuel consumption, travel time and other data;
4. The ability to read error codes and diagnose the car's motor. This allows without long consultation with "specialists" to receive information about all the problems of the power unit.

Some of the models have addition to the main functions, among which may be:

• Information on the timing of the next maintenance of the machine;
• Some making adjustments of basic functions;
• Control over the insurance period;
• The presence of organizer functions;
• The ability to set the parameters at which it will be possible to turn on the fan in the cooling system.

On the principles of functioning of such systems

VAZ 2109 carburetor machines have been equipped with appliances with router functions. Installation of injector power plants VAZ 2114, VAZ 2115 and other models, demanded the use of a completely different type of device. Most of its functional activities are assigned to diagnose and managing the work of almost all devices and car systems.

The work of BK VAZ 2114 is based and has the following principle of operation:

1. Making signals from sensors through the control unit, processing them and issuing messages to the display, as well as the ability to make adjustments for other systems;
2. Treatment of signals from systems that are not controlled by the controller. In case of emergency situations, an appropriate icon is displayed on the information board, and the sound signal is supplied.

How to use such devices: a brief instruction

For installed devices, an instruction is attached for a regular onboard computer VAZ 2114. It informs it in detail and instructs the owners of the machines about what needs to be done in one way or another. Let's talk about how to use the on-board computer VAZ 2114. For competent use, it is necessary:

• These Trip Computer are very complex electronic devices endowed with more than 500 different functional duties. All this requires a careful study of this device. The instruction manual helps in this. It is well studied with the information board included;
• Most of all attention when learning should be given to the icons and symbols of emergency teams.
• It has buttons that are managed by the work of the BC VAZ 2114. It is necessary to study and remember the rules for working with them.

When choosing such devices, there are no special requirements for them. The selected model must support programs 2114. Today, the cost of the on-board computer VAZ 2114 may have from 1500 to 4000 rubles. In online stores you can find even more these products.

Immediate all possible error codes displayed on the information board does not make sense. They are not needed as at school to tell by heart. We live in the age of online technologies, find the designation of these error codes, print and take with you in the machine. In the case when you see characters on the information board, you will be able to quickly take the right decision. Continue moving on, or call technical assistance. Unfortunately, there are cases when the on-board computer is mistakenly issued a danger signal. The culprit in such cases may be some sensor or processor itself. No one is insured against electronics malfunctions, but in most cases, the scoreboard signaling about reliable information.

Below will show basic possible error codes on this machine.:

• 2 - the power supply voltage is exceeded;
• 3 - problems with;
• 4 - a malfunction with the sensor that monitors the temperature mode of the motor;
• 5 - incorrect signal from the outdoor air temperature sensor;
• 6 - a signal of overheated motor;
• 7 - too low car lubrication system;
• 8 - Problems with braking system;
• 9 - submractive battery.

You should react to codes 4, 6 and 8 that need to be eliminated and only then continue to continue. After elimination, a processor reboot is required. Errors are discharged by pressing and holding the daily mileage key.

What to do when the BC ceases to work

This sometimes happens that the on-board computer does not work. What do specialists advise in this case? First you need to decide on. If it does not show "signs of life" at all, F3, which is installed in the power supply chain of the VAZ 2114 processor. If its replacement has not made a "revival" in its operation, check the connection connectors.

Describe the essence of the repair process of such a complex electronic product, it makes no sense, since for this, in addition to the presence of the necessary devices and tools, it is necessary to have an additional education in the field of electronics.

On-board computer (BC) is an automated car control system. There are several types of BC to find out which type is installed on your car, it is necessary to read the content of the stickers on the device. Depending on the type of engine, the corresponding types of BC are selected. For injection engines of the car, the most automated control systems are made. Multitronics can be considered the most versatile onboard computer for VAZ 2114.

Purporing computer purpose

Those who put on their own on-board computer, namely, this is the name of this innovation, providing additional control, believe that its functions are able to satisfy the requests of even the avid car enthusiast. At first glance, this electronic device demonstrates the characteristics that were presented on the control panel of various models of the vase, including the 2114th. The clock and so is in every car, as well as a speedometer (speed meter), tachometer (shows engine speed), odometer (responsible for mileage).

However, they, however, quite harmoniously bang in front of the driver, decorated in properly. Yes, and other parameters are present here: how much fuel in the tank, there can even be indicators of the thermometer that reflect the indicators of both the outer and intra-alone air states. Everything is performed according to the highest standards of autody sodesign. But the control systems (on-board computer) are not just the different different indicators in one screen.

Differences of the BC from the control panel

Drivers with experience know that the speedometer simply recalculates the engine speed into the speed, and it is necessary to change the wheels to a larger diameter as the speed will increase, although the indicator will work "in old manner". In order not to get asked to the next post of traffic police, without BC could not do. But much remains not accounted for by simple locks, and in the far road will be quite relevant factors such as actual and averaged fuel consumption, information about overcomed by a kilometer, about the amount of fuel and so on. These parameters of the VAZ 2114 can be calculated, but before that the driver who is primarily obliged to follow the road, and not to do the calculation.

"Smart" car 2114 himself will ensure that the car does not overheat in the heat, and the most advanced onboard computers - even about the danger of ice formation in frost. Report the computer and about the voltage within the engine system. With such an assistant, the ride will be much safer, for short or long distances. The main thing is not to ignore the preventive signals of the computer.

It may seem that the indicator appeared on board, which began to calculate the indicators. But in fact, the data of the equipment of the equipment and before were known, they simply did not shielded before the driver. However, why was there a passenger car interior into a pilot cabin? Connecting "Bortovik" (onboard computer) to all existing sensors inside the machine, processing the data obtained and their feeding in a user-friendly form is the main task that is assigned to the BC.

The task of the on-board computer is not only to collect information from the car sensors, but also to process it, adjust, analyze and output in a user-friendly form.

Connecting onboard computer

The model of the car VAZ 2114 is already equipped with a prepared place to install the on-board computer. As a rule, the "Multitronics" or "State" computer is very likely. Many car enthusiasts who experienced all of their charms recommend to stop their choice on these brands. Moreover, there are options for this device with a color screen - for lovers. But this is no more than additional convenience and, except for "beauty", no particular differs from predecessors.

To connect the on-board computer, you will need to perform some mandatory operations:

• First of all, the device itself should be connected to the power. For this, a constant current + 12V existing in the VAZ is used.
• In order for the BC to run automatically simultaneously with the power on, the power to ignite the engine should be connected to it. If you connect to the electroiler with overall lights, then the computer screen will be slightly "pretty", which is very convenient when dark.
• Be sure to connect the mass.
• Serve or not feed the signal from the fuel level sensor (DUT) depends on the model used by the BC. Some of them themselves are theoretically consider how much it is already used, depending on the indicators of the instantal consumption of fuel and its initial presence in the tank.
• It also remains to connect the diagnostic line of the K-Line controller.

If there are no pads in the onboard computer

As a rule, for all these procedures, it is sufficient to connect a standard four-contact block with adapters, which are provided when the side computers are configured. In case it is missing, there should also be problems. The common nutrition can be "borrowing" from the cigarette lighter, the autorun - from the ignition lock, the "muffler / dimensions" - from the illumination of the same cigarette lighter, the mass - from the body or again from the cigarette lighter.

So that no troubles occurred during the above action described, the mass of the car battery is worth disconnecting.

The signal from the fuel level meter (DUT) should be taken from the wire, according to the wiring scheme of a particular car VAZ, as connecting the diagnostic line.

However, in the instructions that attached to the BC, everything is described in detail, so, strictly following it, it is quite difficult to make a mistake.

Even if the "bortovik" got as a gift and possibly without recommendations, they can be searched on the Internet, including on the forums. But, as a rule, all of them are standard and depend simply from strictly execution.

A trip to the route computer, as it is also called it, will not prevent surprises on the road. Car condition The driver will be able to control independently and challenge once every time for diagnostics (quite expensive procedure) will not be necessary.

Upon exceeding the very probable value of the path - 9999 km, there is an automatic resetting of all route characteristics.
Not counting the bosch mp7.0

Attention: Starting from version 12.04 and above, the route computer does not have the ability to set the identification code. Accordingly, the purpose of the 8 "display of settings 3" is changed. Watching the group "Code Change" introduced a group of choosing a method for calculating a run of a mileage on a fuel residue in a tank: on the basis of the average combustible consumption per 100 km and on the basis of the average fuel consumption over the last 10 km.

For the proper functioning of the device, the device uses the method for automatically determining the exchange protocol to the line. The user can use the automatic exchange of the exchange protocol, or manual mode is used, with all this it is necessary to correctly specify the type of the ECU with which the device must operate. In coordination with the installations of MK Comfort X11, X10 organizes an exchange of diagnostic to-line. With a repeating exchange of MK, it requests a number of characteristics from the computer, which, after appropriate processing, are displayed on the device screen. The introduction of the exchange protocol for the diagnosis is significantly expanding the multifunctional MK capabilities. The user gets the ability to control a huge number of research characteristics, such as the temperature of the motor, the position of the throttle valve, mass air flow voltage on the oxygen sensor, etc., and also gets the opportunity to create a drying of the spark plug, adjust the temperature of the radiator fan. The introduction of the K-line also implies the ability to read, decrypt and reset error codes. Measurement of the voltage and outdoor temperature in the mode of operation with the to-line of diagnostics, but is made specifically the MK itself (these characteristics are not read from the to-line).

The user has the ability without the help of others to choose the characteristics displayed on three different monitors (Jouser monitor 1,2,3). View of the monitor of the user 4 (day), maintenance monitor, and installation monitors can not be changed.

The variable characteristics calculated by the device, as well as installations, the amendments and the options of the user are saved in the non-volatile memory of the device, after disconnecting from the power supply (AKB). But the complete shutdown of the device from the battery leads to the reset of the current time.

After 20 seconds after turning off the ignition lock, MK Comfort x11, x10 disables the monitor backlight, but the indication of the characteristics of the burning when the ignition lock is turned off after clicking on the device buttons is saved. On-board computer Multitronics Comfort X11. X10-PDF Size how to choose onboard. Warranty - 1 year. The on-board computer Comfort X10 is installed in the regular place of clock cars VAZ of the 10th family. In those familiar to the monitor, in which the characteristics are placed that, when the ignition is turned off, have an indefinite value, for example: the instant fuel consumption, the temperature of the motor, etc., after disconnecting the ignition lock, zeros are displayed or dashing. Multitronics Comfort X11 onboard computer - Multitronics. When the monitor is disabled, the device consumes from the battery less than 0.03a

User Display 4. "Day" allows you to monitor the average pretended characteristics for one day, regardless of the common specific characteristics that are burning from reset to reset. With all this, the user can create a cost of travel, depending on the entered price values \u200b\u200bof the fuel, time price of the mileage, and the run prices are 1 km of way.

Setting on-board computer Multitroniks

On-board computer (BC) Created to promote the population of the Earth in the driving of the car.

It is intended for reading the information of the machine and transfer it to the screen on which the driver will be informed about how much fuel was spent, to obtain all the information about electricity in the car, the vehicle speed during the movement, the air temperature in the cabin and outside it, and almost All other.

Many people will see the question of why it is impossible to use standard devices for measuring speed, air temperature, etc., but the answer will be quite common, no matter how standard devices would not be in the car, the BC will cause all the information at times more precisely and more.

It is also worth the cancellation that the BC is not a matter of the subject of luxury, but one of the main items in each salon.

Features

When choosing it is worth sending attention to the ECU of the motor of your steel stallion, as they are divided into three types.

All foreign-made cars have on-board computers in stock, and because the owner of this car with the presence in its own salon of this device will carry more currency loss, but we assure you that it is to pay.

So let's look at what functions own onboard computers. In this video, you will be familiar with the annotation on the installation of the Multitronix BC.

Read:

At first, each bortovik is an electrical device. Also, this unit assumes all the acts that are associated with the counting and submission of information to the driver.

Also, the BC display shows all the information in which the driver needs when driving the vehicle.

Some, are arranged so that in the event of a breakdown of a certain inner part of the car. They will be able to work for it.

The functions that bortovik Multitroniks have, have a rather different temper. Any brand of bortovikov makes a huge number of different functions.

In this article, you will find a reference resume for the driver.

The on-board computer MARK Multitronix has the following functions:

• Suitable for forty different protocols.
• Notifies about defects, it also decrypts the code of this error.
• The voice notifies the exit of the car beyond the boundaries of ordinary criteria.
• Also, the voice is also called all the provided program characteristics.
• The voice puts in the notice number of gasoline in the tank, especially comfortable at refueling.
• Also given on-board computer It has a property of keeping accounting travel by car, where it is installed.
• The Multitronix BC has a property to keep the quality of the gasoline bought in the pot.
• Also the device intently looks at gasoline consumption.
• It has a voice property notify about the overall lights that the driver forgot to turn off.
• It can provide the optimal temperature in the car cabin for its passengers.

There's nothing difficult in this if you think about it), set up once and ride enjoying, bortovik thing is useful ...

An important function for many drivers is to control the fuel bought to the quality. Also, this device has one excellent quality that distinguishes it from many other on-board computers, it is saving gasoline. After all, Multitronics itself regulates the desired gasoline injection.

Also with the help of the Multitronix BC, you can increase the safety of your personal transport during parking.

Installation and principle of operation of the BC Multitronix

In this video, you will be shown that it is included in the kit, as well as the installation and configuration of the on-board computer Multitronix. Happy viewing!

Car enthusiasts sooner or later understand that their car needs a side computer and most drivers face that it is necessary to establish it.

We assure you that the installation method on-board computer Will not be much difficult for you if you read this article.

• In order to connect this device to the system of diagnosing your car, you will need to find a special connector, which is called a diagnostic shoe. Also in the on-board computer should be a special connector for connecting to your car. If the connector does not fit, then you should not worry and panic, as there are many types of adapters.
• After you managed to connect the wire into two connectors, to the diagnostic shoe and the connector in the computer, you should configure the computer. Information from the machine is read if the car is equipped and the engine works. In the Multitronix computer there are two ways to work this unit. The first method is the user mode, and the second installation mode. And it is in the installation mode that you need to make multitronix settings.
• First of all, to configure it, you need to select the type of electrical block and determine it first in the list. Or choose another way that will be simpler, then it is to provide the entire automatic selection system. After that, it is worth indicating the amount of fuel that is located in the tank of your car and its consumption is 100 kilometers in liters. You must create a flow table and make its data into the system, well, the device on this table itself already counts and gives gasoline consumption on the screen.
• Next, in the mode of the method of operation of this unit, select the method of work as user mode. And in this mode, you choose exactly the parameters with which you would like to see the scoreboard. All this will depend on what functions this device has. Well, Multitroniks has over two hundred features. It is also necessary to adjust and set the temperature at which the fan should be turned on. It is very important to adjust the cooling temperature of your car, because each car is peculiar to have different temperatures. Also adjust and set the time, screen backlight, date on-board computer.

You must understand that the Multitronix BC setting is not so heavy, but you should delve into each function that this device has.

The above functions are arranged as standard and you can adjust them without any problems, but it would be necessary to adjust, change, and change the data of other functions, you will need to contact the center that specializes in this diagnosis.

Also, the motorist can more comfortably ride on his personal transport.

In the event of a breakdown of the BC, you will greatly be disappointed in it by learning the price for repairs. In addition, since such a type of car modernization is not yet very common, the price will be too large, so take care of it.

Very successfully turned up MK 2114-3857010 for 300 rubles 😉
Since I have long wanted to put the bortovik, but the prices for him, to put it mildly, bite - I took without thinking! 😊
The mincer features all the necessary basic functions.
The backlight of the display and signatures of the buttons is made in a traditional vasescale style - green-yellow. When you click on the MK buttons begins to make sounds ... Beeeee ... 😥

Since the old owner was not particularly talkative and did not really explain what kind of MK, I began to look for instructions for this miracle of technology. The funny thing is that there is no shelter. There are records about how someone bought and put the same MC and TP, but not instructions.

After I reset the MK after the old owner, more or less figured out the functionality:
MK is reset by parsing and pulling out the battery
When you first connect to meals, MK welcomes playing midi melodies - a la old Nokia-brick.))))

So, the buttons from the left-topoint:
1 COINT T.
1.1. Travel time without stops. Pasters the fight while the MK is turned on. You can reset long by pressing the start,
1.2. Total travel time for all trips

If you click on the start, you can set the backlight brightness - the plus and minus keys. Select a value from 0 to 100%

2. KM / H button
2.1. Middle speed on the trip
Pressing the start in this menu includes turning off the alert. (I have not understood what kind of alert)
2.2. Average speed for all time
If you click on the start in the menu 2.2, you can put a speed limit, for example, at 120 km of MK starts to delete

3. Button KM
3.1. Kilometer travel
3.2. How many kilometers can you drive until the next refueling

4. L. button
4.1. The number of liters in the tank - after zeroing is not active yet. Most likely it will be displayed how many liters have been flooded for all time
4.2. Spent fuel from the last gas station

5. L / 100 button
5.1. Fuel consumption per 100 km

7. N. button
7.1. Clock. Exhibited by pressing start, then plus-minus

7.3. Alarm clock. Put the same

Plans to make Peresvet with green-yellow on white or red with an inverted screen.
Ensure this MK - it seems to be problematic, because it will take off the display is a whole story.

The computer is today an ordinary device with which a large number of people face both at home and in a large number of vehicles. Specifies more specifically about car drivers, a computer, or as you are familiar with it, the on-board computer has become an indispensable to each of them, because only with it you can take control of the work of most aggregates.

Video about the work of an abnormal BC on VAZ-2114:

If we talk about cars produced in Russia, then the firstborn in the AvtoVAZ family, it was the VAZ-2114 that the on-board computer was mounted directly from the factory, which was able to notify the driver about all the events occurring, both beyond the way and in the cabin. Below in this article we will analyze in detail why the on-board computer is needed, and we will analyze a brief instruction to it.

Causes of the installation of the BC in the car

Standard place in the instrument panel for onboard computer. The photo stands the plug.

The on-board computer of the first version mounted on the VAZ-2114, even had some functions, however, with ease watched the main parameters of the car:

• Fuel control And its calculation about the number of kilometers past - this feature allows the driver to make a decision about refueling in advance.
• Cooling fluid temperature control - This feature eliminates the overheating of the engine due to the timely user informing.
• Diagnostics of individual vests of the car - allows with maximum accuracy, and most importantly mobility, detect and eliminate the problems that have arisen.

Learn more about onboard computer functions

Onboard computers on VAZ-2114 are able to display the following information to their work screen:

• Instant performance of the engine, its turns, temperature, reality testimony and medium fuel consumption.
• Information about car run, time on the way.
• The ability to unmistakably read errors that have arisen in the system, which will allow you to immediately determine whether it is worth handling a malfunction in the car service or it is possible to correct everything with your own hands.

Modern onboard computers, by type Multitronics - C340. And his counterparts also know how:

• Control and inform the driver about the next technical inspection, car insurance, thereby the function of the organizer.
• Independently change the parameters of the fan, change the notifications of a sufficient mechanization warming temperature.
• It is possible to connect the parking sensors.

Note, in order to activate both other, extended functions in your BC, it may be necessary to firmware.

Principle of operation of the BC on VAZ-2114

Not standard onboard computer

The principle of operation of the on-board computer at first sight will seem primitive, however, in fact it is a technically complex device that simultaneously accepts, processes and, if necessary, notifies the presence of faults. The alert function takes place on the screen of a special icon and feeding a certain beep ..

Brief user manual

For all the on-board computers supplied on the VAZ-2114, there is its own user manual, and if it is not in the paper version, it can be easily located on the Internet, just to know the brand and model of the device. Despite the fact that the variants and models are many, the basic functionality in them in principle is similar.

The readings of the onboard computer.

• If you are just going to buy the BC, then you need to know whether the specific model is suitable for the ECU of your car. As a rule, all the information already has the seller, and there should be no difficulties in this.
• It is better, first of all when familiarize yourself with the onboard computer to pay the time to the symbols of emergency commands and visual icons appearing on the display.
• Pay attention to the location of the buttons, and the rules for working with them, in order to quickly react to change the parameters in motion (on some BC models, the keys can be blocked at a certain vehicle speed - approx.).

Error codes for VAZ-2114

Since the ECU on all VAZ-2114 is similar or, at least, it is similar, then write in advance, and even more so remember them does not make any sense, the benefit of some models are capable not only to bring it on the screen, but also voice out all problems available in the car .

The best option for determining and refineing faults will be the printed version of the error codes on the VAZ-2114. You can take them on the official sites of plants manufacturers of BC for VAZ-2114, and below we will imagine you, the most frequent errors that are found on the "fourteenth":

Codescription 0102, 0103 Incorrect signal level of the air flow control indicator. 0112, 0113 Inlet air temperature indicator signal is needed to replace the element. 0115 - 0118 Incorrect signal of temperature measurement element Co. - Need to replace the sensor. 0122, 0123 Interference or incorrect signal of the control indicator of the throttle position - it is desirable to replace the element. 0300 On-board computer (BC) revealed random or multiple ignition passages - in this case, the car can not start immediately. 0201 - 0204 A cliff in the nozzles control circuit is recorded. 0325 The on-board computer was recorded a cluster in the detonation device chain. 0327, 0328 The breakdown in the detonation sensor is necessary to replace the device. 0480 Failed the cooling fan - you need to replace the element. 0505 - 0507 There are malfunctions in the functioning of the idle regulator that affect the number of revolutions (lower or higher). If this code occurs, the regulators need to be replaced. 0615 - 0617 In the diagnostic process, clips or closures in the starter relay circuit were revealed. 230 This error code means the breakdown of the fuel pump relay - the device must be replaced as soon as possible. 1602 It is one of the most encountered codes in the diagnosis of BC for malfunction. Means the disappearance of the on-board network voltage on the electronic control unit.

What to do if the BC stopped working

It happens that the BC stops working or the information that it should transmit and analyze is not transmitted. First of all, it is necessary to pay attention to the integrity of the electrical circuit. Namely fuse F3 responsible for its performance, then check the integrity of the wires that go to the diagnostic block, and ensuring its nutrition. You can connect the on-board computer to the VAZ-2114 system in this article.

Describing the process of repairing the ongoing computer it is pointless, because such devices are broken not often and little maintainable, therefore have technically complex mechanisms that require professional tools and skills.

Let's start with the fact that installing the on-board computer in a regular place on the VAZ 2114 and other Samar models is not so difficult. In the installation of the onboard computer, in principle, there is no harves with wires and nuts (unless, of course, no one has tried to you in the car and changed nothing). A knowledgeable person will set you a on-board computer for some 2 minutes, so you should not be afraid of your hands on your feet and forward with the song \u003d).

Why do you need an on-board computer?

In past articles, we have already said that such a on-board computer, for which it needs and what kinds they are. But I will allow myself to repeat so that you clearly realize all the advantages of the existence of a side computer, and there are probably no consumers, except that the waste of money for the purchase and that's it.

Take, for example, on-board computer Staff 115 × 24. Having this model in its presence, you can:

1. set the radiator fan launch temperature; This feature is very useful, for example, in the winter period of time, when you can control the temperature of the coolant, thereby monitor the stove radiator temperature.
2. the function of drying and heating the candles before starting the engine is very helpful.
3. resetting the settings and computer adjustments are needed to go to gasoline with a higher or low octane number (from 92 to 95 and vice versa), this feature is also needed to reset the settings after a long trip with an increased engine load.
4. the ability to read errors allows you to monitor the condition of the car, on time to change the non-working sensors, items.

Installation instructions onboard computer

In this article, we will consider the installation process of the Prestige side computer with the diagnostic and error reading feature.

To work, we will need:

• Screwdrivers
• on-board computer,
• the wire is 1M long.

Remove the plug on the central torpedo and we are looking for a 9-pin wire block in it. This shoe must be present on all cars of our model. It remains only to connect the block to the computer and everything, but we need to hold the line.

How to spend a line?

1. We take our wire and install it in the second contact of our pad.
2. The opposite end of the wire we throw under the instrument panel at the bottom to the diagnostic pad (for convenience you can unsubscribe the right sidebar).
3. Cutting a wire to a diagnostic pad, connect it to the "M" jack if you have a shoe of Euro-2 or in the 7th socket, if you have a shoe of Euro-3 (very often occurs that the diagnostic shoe on Euro-3 is installed on the car up legs, consider it)
4. Now connect the on-board computer, insert it into a regular place and check it.

For a more complete and visual presentation of work, a scheme is presented.

What if under the instrument panel there are no pads for onboard computer?

In this case, it remains only to assemble a new block: buy a 9-pin block and carry it to it according to the following scheme:

• fuel Consumption Signal (Green Wire)
• ignition (orange wire)
• + 12 volts (red / white wire) red wire with white stripe
• mass (black)
• speed \u200b\u200bsensor (brown wire)
• 6k-line (most often gray or black wire)
• mute (green / red wire) Green wire with a red stripe
• illumination (white wire, or can be taken from the dimensions button)
• fuel level sensor (pink)

Errors when connecting / operating onboard computer

Error: "There is no connection with the controller" or "cluster to-line".

This error indicates that the to-line is not connected or a contact occurred. Check the wire according to the scheme described above. Most likely flew contact with the diagnostic pad.

Error: Incorrect readings of the intangular temperature sensor.

If you have a temperature overboard -40, it suggests that the wire breakdown occurred to the temperature sensor, or there is no such sensor at all. If the temperature is for example -25, and on the street only -10, then you need to replace the sensor for a good.
