Description of the on-board computer

What is an on-board computer in a car and what tasks does it perform? First, let's look at some theoretical points. BC is an electronic unit that allows you to react and control various processes in the operation of various auto systems. That is, thanks to the BC, the driver will always be able to receive data on the operation of certain components. We figured out what an on-board computer is, now we will tell you about its purpose.

What the on-board computer shows:

• the device demonstrates the consumption of gasoline in different driving modes;
• allows you to control injectors, as well as the vehicle ignition system;
• monitors the operation of the transmission;
• can control various additional two-way communication systems, for example, a rear view camera, etc .;
• allows you to determine the pressure level of the engine fluid, the temperature of the antifreeze;
• regulates the voltage level in the car's electrical circuit, controls the battery charge;
• if the vehicle is equipped with a climate control system, then the BC also controls it;
• one of the main options - an on-board computer for a car allows, if necessary, to read error codes and show them on the display so that the driver can decipher them and find out where to look for a breakdown.

Principle of operation

The principle of operation of an automobile BC for carburetor engines or injection options is not particularly complicated. The device is connected to the chain of controllers and regulators, reads the required data, and then processes the information received. Special software is used for processing. For example, if the BC receives data on fuel consumption according to the scheme, then the software will allow calculating the possible mileage on the remaining volume of gasoline.

All data is displayed on a screen installed in the vehicle interior. The display itself can be digital, monochrome, color, or four or three digits. As practice shows, a monochrome screen with a diagonal of 2 inches is quite enough to show the driver more than ten parameters. More modern BC options today are equipped with a high-precision LCD screen.

Kinds

Today, there are several types of CD:

1. Universal option, such a device combines various options and gives the car owner the opportunity not only to control the car, but also to surf the Internet. The main purpose of such a device is to increase the comfort for the car owner while driving. Usually a universal on-board computer has a screen with a diagonal of 6-14 inches, a keyboard can be connected to newer models. It should be noted that in their design such BCs are very similar to ordinary computer PCs, but one of the features of the devices is a low degree of integration with the car's electrical system.
2. Route. The trip on-board computer allows you to determine the parameters of the car's driving, while it does not have to be connected via GPS to the satellite. However, newer models are equipped with GPS receivers anyway. With the help of such a device, the driver will be able to determine the average speed of the car, fuel consumption, the remaining distance to a particular point, the distance traveled, etc. In addition, depending on the model that you install in your car, the device may have the function of calculating the fuel consumption during emergency braking or fast acceleration. Typically, BCs of this type are installed in the control panel.
3. Manager and service bookmaker. The purpose of such computers is to determine the breakdown of the main units of the vehicle and to warn the car owner about this. As a rule, such a BC is an integral part of the machine control system, but depending on the model, it can also be an independent device with extensive functionality. When checking the car, all combinations of errors are stored in the device's memory and will remain there until the error is corrected and the memory is reset to zero (the author of the video is the AvtoGSM channel).

BC setup

Making an on-board computer with your own hands is a difficult task at home. To manufacture a device, you will need many different elements, including a display, a microcircuit, buttons, etc. It is impossible to make a computer on your own without experience in assembling such devices, so if you want the device to work correctly, then it is better to order this procedure or buy a new BC.

If you decide to put an on-board computer for carburetor or injection engines on your car, then you need to know how the device is configured correctly:

1. If necessary, you can always activate the automatic configuration option - then the device will automatically accept the required configuration.
2. If this option does not suit you, then go to the settings menu - find the desired block and select it. It should be noted that in this case, the BC must be configured as the main device. One of the important roles in the configuration is determined by the choice of the mode, thanks to which the fixing of fuel costs will be carried out.
3. By setting this parameter, you have several options. One of them is a linear relationship, in which case the parameter will always depend on the control unit. If you decide to configure manually, then first you will need to make a table on fuel consumption. Taking into account this information, BC will carry out calculations and display the corresponding parameters on the screen.
4. In addition, you will need to determine the parameters that the screen will start showing, depending on the model, their number may be different. Separately, the parameter responsible for the activation temperature of the motor cooling fan should be highlighted.

Issue price

The minimum cost of a bookmaker from the Multitronics company will be around 130 rubles. More expensive options can cost 7,500 rubles.

Sorry, there are currently no polls available.

Video "How to make a bookmaker with your own hands"

Detailed instructions for making a circuit are presented in the video (author - libral1973 channel).

The cars of the "Tenth Family" always have a clock or a computer next to the display unit. Now such computers are called "on-board computers" (BC). The computer display with the ignition off shows the time, but this is not its only function! We list all the capabilities of the on-board computer on the VAZ-2112, and the instructions supplied by the VAZ will help us with this. Tables were copied from the instructions, which are important when setting up.

What bookmaker are we talking about? The answer is shown in the video.

The front panel is shown in the photo below. You need to remember the main keys: 1, 2, 3 and 5. All functions are divided into three groups. By pressing button 1, you can scroll through the functions of the first group. The same applies to other keys.

Regular BC for the hatchback "Lada-112"

The question is, why do we need button 5? When in any of the three groups, this button activates additional functions. By the way, their number is equal to two.

Each group has different additional functions.

Swipe example

When the ignition is off, we see a clock on the display. Let's try to turn on the ignition and press key 1. The button itself can be pressed any number of times - the functions are switched cyclically. Their number is three.

Function group "Time"

If you need additional functions, press button 5. We have considered how to use the standard on-board computer on the VAZ-2112, but the instructions are suitable for any "Tens".

BC operation in different modes

The above is how to use the BC in the "Time" mode. The "Time" group is the first, but there are two more - "Fuel", "Way". We give tables for them.

Function group "Fuel"

Above is the table for buttons 2 and 5.

Function group "Path"

The functions activated by buttons 3, 5 are shown here.

Programming instructions

We will change different settings. And we will also try to turn on the alarm, change the brightness of the backlight, etc. Thus, computer programming on the VAZ-2112 also applies to operation.

Configuring the fuel level sensor

The tank is initially empty. Turn on the "Fuel level" function (2-5) and press button 4 for more than two seconds. Then we follow the steps:

1. Press button 3 for one second until the sound signal appears;
2. We fill the tank with three liters of fuel. Wait 10-20 seconds and repeat step 1;
3. Repeat steps 1 and 2 until 39 liters are filled.

We activate the overspeed alarm

By pressing button 3 we turn on the "Average speed" function. Press button 4. Next, use buttons 5 and 6 to set the required numbers. Finally, press button 4.

To disable the option, use a high threshold value: 190 or 200 km / h.

Change the brightness of the backlight

We use function 1-3 "Time with stops". Press button 4. Use keys 5 and 6 to adjust. Press button 4.

Alarm clock

Go to the "Alarm" option (an additional function in the "Clock" list). Press button 4. Next, set the hour value (keys 5 and 6), press button 4, set the value of minutes (keys 5 and 6). By pressing button 4, the alarm is activated.

An alarm clock in a car is a necessary thing

It remains to figure out how to turn off the alarm. Follow all the steps to set the hour, and then press the button 1. The alarm should turn off!

How to customize your calendar and clock

We have reached the most difficult chapter. Let's go straight to the action:

For quick adjustments, follow step 1 and step 2. If you then press button 1, the hours will be rounded up from 13:57 to 14:00. Or otherwise: it was 14:05, but it will become 14:00.

Our editorial 2112 with BC Gamma GF 212. We are completely satisfied with it

The most popular non-standard ammo on the VAZ-2110 is the Gamma GF 212 model.

Its cost about 2500 rubles ... Installation is simple, you just need to connect to the K-line in the diagnostic connector and bring the power wires.

There are such useful functions as blowing out candles and more. We can only recommend it from ourselves among the large variety of models on the market.

Attention: starting from version 12.04 and higher, the trip computer does not have the ability to set an identification code. The purpose of group 8 "Settings display 3" has been changed accordingly. In place of the “Code change” group, a group is introduced to select the method for calculating the forecast of the mileage on the remaining fuel in the tank: based on the average fuel consumption per 100 km and on the basis of the average fuel consumption over the last 10 km.

For the correct functioning of the device, the device uses the method of automatic determination of the K-line exchange protocol. The user can use the mode of automatic determination of the exchange protocol, or the manual mode is used, with all this, it is necessary to correctly indicate the type of ECU with which the device should work on the K-band. In agreement with the MK Comfort X11, X10 units, it organizes the exchange via the K-line of diagnostics. With a repeated exchange, the MC requests a number of characteristics from the ECU, which, after appropriate processing, are displayed on the device screen. The implementation of the K-line diagnostic protocol significantly expands the multifunctional capabilities of the MC. The user gets the ability to control a huge number of research characteristics, such as engine temperature, throttle position, mass air flow, oxygen sensor voltage, etc., and also gets the opportunity to create spark plug drying, 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 voltage and outside temperature in the mode of operation with the K-line diagnostics, but, is done specifically by the MK itself (these characteristics are not read from the K-line).

The user has the ability, without the help of others, to select the characteristics displayed on three different monitors (User Monitor 1,2,3). The views of User Monitor 4 (Day), Maintenance Monitor, and Installation Monitors cannot be changed by the user.

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

20 seconds after the ignition switch is turned off, MK Comfort X11, X10 turns off the monitor backlight, but the indication of the characteristics that are vital when the ignition switch is turned off after pressing the device buttons remains. On-board computer multitronics comfort x11. X10-pdf size how to choose onboard. 1 year warranty. The comfort x10 on-board computer is installed in the regular place of watches of cars of the 10th family. In those familiarity of the monitor, in which there are characteristics that, when the ignition is off, have an undefined meaning, for example: instantaneous fuel consumption, engine temperature, etc., after the ignition switch is turned off, zeros or dashes are indicated. On-board computer multitronics comfort x11 - multitronics. When the monitor backlight is off, the device consumes a current of less than 0.03A from the battery

User display 4 "Day" allows you to keep track of the average performance characteristics for one day, regardless of the general performance characteristics, which are relevant from reset to reset. With all this, the user can create a calculation of the price of a trip, depending on the entered values \u200b\u200bof the price of fuel, hourly price of mileage, and price of mileage of 1 km.

Customization on-board computer Multitronics

On-board computer (BC) was created with the aim of helping the people of the earth to drive a car.

It is designed to read the information of the car and transfer it to the screen, on which the driver will be able to be informed about how much fuel was consumed, get all information about the electricity in the car, the speed of the car while driving, the temperature in the cabin and outside it, and almost everything else.

Many people will wonder why it is impossible to use standard devices for measuring speed, air temperature, etc., but the answer will be quite common, no matter how many standard devices there are in the car, the BC will determine all the information at times more accurately and faster.

It is also worth canceling that BC is not some kind of luxury item, but one of the main items in every salon.

Features:

When choosing, it is worth paying attention to the engine ECU of your steel stallion, since they are divided into three types.

All foreign-made cars have on-board computers available, and therefore the owner of this car with this device in his own salon will incur more currency losses, but we assure you that there is something to pay for.

So let's see what functions the onboard computers have. In this video, you will be introduced to the annotation for installing BC Multitronics.

There is nothing complicated in this if you think about it), set it up once and enjoy driving, Bortovik is a useful thing ...

An important function for many drivers is the quality control of the fuel poured into the tank. Also, this device has one excellent quality that distinguishes it from many other on-board computers, it is the economy of gasoline. After all, Multitronics itself regulates the required injection of gasoline.

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

Installation and operating principle of BK Multitronics

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

Car enthusiasts sooner or later realize that their car needs an on-board computer and most drivers are faced with the fact that they need to install it themselves.

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

• In order to connect this device to the diagnostic system of your car, you will need to find a special connector called the diagnostic block. Also in the on-board computer there must be a special connector for connection 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 have managed to connect the wire to two connectors, the diagnostic connector and the connector in the computer, it is worth setting up the computer. Information from the car is read if the car is started and the engine is running. In the Multitronics computer, there are two ways to operate this unit. The first is the user mode, and the second is the settings mode. And it is in the settings mode that you need to make the settings for Multitronics.
• First of all, to configure it, you need to select the type of electrical unit and define it first in the list. Or choose another method, which will be simpler, then this is to provide the entire system with automatic selection. After that, it is worth indicating the amount of fuel that is in the tank of your car and its consumption per 100 kilometers in liters. You must create a consumption table and enter its data into the system, but the device calculates everything according to this table and displays the gas consumption on the screen.
• Next, in the operation mode of this machine, you should select the operation method as user mode. And in this mode, you select exactly those parameters with which you would like to see the display of the bortovik. All this will depend on what functions this device has. Well, Multitronics has over two hundred functions. It is also necessary to adjust and set the temperature at which the fan should turn on. It is very important to adjust the cooling temperature of your car's engine, because each car tends to have different temperatures. Also adjust and set the time, backlight, date on-board computer.

You should understand that setting up BC Multitronics is not so difficult, but you should delve into every function that this device has.

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

Also, the car enthusiast will be able to ride his personal transport more comfortably.

In the event of a breakdown of the BC, you will be very disappointed in it, having learned the price for repairs. Since this type of car modernization is not yet very common, the price will be too high, so take care of it.

The time has passed when the word computer was spoken aloud by a few people. Today this device is found in almost every home and has become a standard device in automotive technology. He has become an indispensable assistant for drivers, as he took over the functions of monitoring the operation of most of the units of modern vehicles.

PURPOSE AND BASIC FUNCTIONS

Cars manufactured in Russia are equipped with such a device. So, for example, the regular on-board computer became the firstborn in the family of VAZ cars. In simple terms, it is a car directory on wheels. The driver needs it in order to know what is happening both inside the car and outside.

WHY IS IT INSTALLED IN A CAR

The first versions performed few functions, they were as follows:

• Control over the availability of fuel in the vehicle and the distance that can be covered by it. This will help the driver make the right decision to refuel or stop driving in time;
• Monitors the worker in the motor and helps prevent overheating.

Using more expensive versions of computers allows you to diagnose individual components and assemblies of the machine.

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

1. To be promptly informed about problems that have arisen in a particular system of the machine, and to respond correctly to this. Eliminating the problem in its "bud", eliminates expensive repairs;
2. Get savings from car operation.

ABOUT ITS FUNCTIONS

On-board computers VAZ 2114 are endowed with and perform the following basic functions:

1. They display information about which indicators have instantaneous parameters;
2. Display of current information on the information panel;
3. Routing parameters are reported. They mean information about mileage, average fuel consumption, travel time and other data;
4. Ability to read error codes and diagnose a car engine. This allows you to receive information about all the problems of the power unit without lengthy consultations with "experts".

Some of the models have additions to the main functions, which may include:

• Information about the timing of the next service of the machine;
• Some major feature adjustments;
• Control over the insurance period;
• Availability 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 THE FUNCTIONING OF SUCH SYSTEMS

VAZ 2109 carburetor machines were equipped with devices with router functions. The installation of injection power plants VAZ 2114, VAZ 2115 and other models required the use of a completely different type of device. Most of his functional activities are devoted to diagnostics and operation control of almost all devices and systems of vehicles.

The work of the BC VAZ 2114 is based and has the following operating principle:

1. Receiving signals from sensors through the control unit, processing them and issuing messages to the display, as well as the possibility of making adjustments for other systems;
2. Processing signals from systems that are not controlled by the controller. In case of emergencies, the corresponding icon is displayed on the information board, and a sound signal is also given.

HOW TO USE SUCH DEVICES: BRIEF INSTRUCTIONS

For the installed devices, an instruction for the standard on-board computer VAZ 2114 is attached. It informs and instructs car owners in detail about what to do in a given situation. Let's talk about how to use the VAZ 2114 on-board computer. To use it correctly, you must:

• These trip computers are highly sophisticated electronic devices capable of performing over 500 different functional duties. All this requires a careful study of this device from the driver. The instruction manual helps with this. It is good to study it when the information board is on;
• Most attention in the study should be paid to the icons and symbols of emergency commands.
• has buttons that control the work of the BC VAZ 2114. You need 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 a VAZ 2114 on-board computer can be from 1500 to 4000 rubles. You can find even more of these products in online stores.

It makes no sense to memorize all possible error codes displayed on the information board. They do not need to be recited by heart like in school. We live in the age of Internet technologies, find the designation of these error codes, print them and carry them with you in the car. If you see the symbols on the information board, you can quickly make the right decision. Continue driving or call for technical assistance. Unfortunately, there are times when the on-board computer erroneously issues a danger signal. The culprit in such cases may be a sensor or the processor itself. No one is immune from emerging electronics malfunctions, but in most cases, the board signals reliable information.

The main possible error codes on this machine will be shown below.:

• 2 - the voltage of the on-board network is exceeded;
• 3 - problems with;
• 4 - malfunction with a sensor that monitors the temperature of the motor;
• 5 - incorrect signal from the outside air temperature sensor;
• 6 - signal about overheated motor;
• 7 - too low a car lubrication system;
• 8 - problems with the braking system;
• 9 - undercharge of the battery.

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

WHAT TO DO WHEN THE BK STOPS OPERATING

It sometimes happens that the on-board computer does not work. What, then, do experts advise to do? The first step is to decide on. If it does not show any "signs of life" at all, F3, which is installed in the power supply circuit of the VAZ 2114 processor. If its replacement did not bring "revitalization" to its work, check the connection connectors.

It makes no sense to describe the essence of the repair process for such a complex electronic product, since for this, in addition to having the necessary devices and tools, it is also necessary to have education in the field of electronics.

The on-board computer is designed to display the trip time, overboard temperature, speed, voltage in the on-board network, mileage, total fuel consumption for the trip, fault codes, clock and alarm clock.

3 CONFIGURING THE ON-BOARD COMPUTER

3.1 Computer structure

A general view of the front panel of the computer is shown in Figure 1.

The computer has a case, on the front of which there is a panel with a liquid crystal indicator (hereinafter - the indicator) and ten keys for controlling the computer. On the rear wall of the case there is a connector for connecting the vehicle harness. The seven keys are used to select the desired function group and to select functions within the group and have the following designation:

"T", "KM / N", "KM", "L", "L / 100", "ECU", "N".

The "START" key is designed to determine the beginning of the trip and reset the accumulated parameters, to fix the parameter value in the correction mode and to set or remove the parameter control mode.

The "+" and "-" keys are used to increase or decrease the parameter value in the parameter correction mode and to view diagnostic information.

A map for switching indication modes is given in Appendix B. When the ignition is off, the current time of day is displayed on the indicator, the previously set alarm clock will beep at the appointed time.

To reset the alarm sound, press the START key.

Pressing any key other than the "-" and "+" keys turns on the indicator backlight. The type and combination of pictograms displayed on the indicator, as well as the symbols of the parameter units, determine the selected function.

Indication of the parameters: "Current time of day", "Travel time excluding stops", "Total travel time" is accompanied by a blinking dot.

When the alarm clock is set, the current time indication is accompanied by the bell symbol.

The computer monitors the following parameters:

• - maximum vehicle speed;
• - voltage of the on-board network;
• - vehicle mileage on the remaining fuel in the tank.

When the monitored parameter goes beyond the set value: the maximum speed is from 20 to 200 km / h, depending on the installation, the mileage on the remaining fuel is less than 50 km, the voltage of the on-board network is below 10.8 V or above 14.8 V, the bell symbol starts flashing and a sound signal is generated: for the first two parameters with a duration of 3 s and 15 s, there is a pause, the sound signal is repeated twice.

When the on-board network voltage deviates, the sound signal is generated with a 10 s delay and has a duration of 5 s and a 5 s pause, the sound signal is repeated three times. The sound signal is accompanied by the display of the value of the controlled parameter. The sound signal is reset by pressing the START key. After resetting the sound signal, the indication of the parameter that has gone beyond the set value is accompanied by a blinking bell symbol. When the parameter returns to its normal value, the alarm stops. To set or remove the parameter control mode, it is necessary to set or reset the “bell” symbol by pressing the “START” key in the monitored parameter indication mode.

For example, to set the overspeed control mode, use the "KM / H" key to enter the "Instantaneous speed" mode and use the "START" key to set the "bell" symbol on the indicator. Resetting or setting the sound signal of confirmation of pressing the keys is made in the mode of indication of the parameter "Travel time without taking into account stops" by pressing the "START" key.

Indication of the parameters: "Average travel speed", "Average fuel consumption per trip", "Mileage on the remaining fuel" is carried out when the following conditions are met: the parameter "Trip mileage" is more than 1 km and the parameter "Trip time without stops" is more than 1 min, up to if these conditions are met, the indicator displays the symbols "- - - -". To reset all accumulated parameters: "Travel time excluding stops", "Total travel time", "Total fuel consumption per trip", "Trip mileage", in the display mode of one of these parameters, press and hold the "START" button for more than 4 s until a two-tone beep appears.

After resetting, it is necessary to check the state of the mode indicator (presence or absence of the “bell” symbol) in which the reset was performed, since it can change its state. If there is no DVT or a malfunction in its circuit in the "Temperature overboard" parameter indication mode, the "Co" symbols are displayed on the indicator.

3.2 Setting time parameters

Parameter readings correction mode:

• "Current time of day",
• "The calendar",
• The “alarm clock” is turned on and reset by pressing the “START” key.

The corrected digits of the parameter are indicated by flashing. The required parameter value is set with the "+" or "-" keys. If the "+" or "-" keys are held for more than 0.5 s, the autorepeat mode is activated. The clock is set according to the exact time signals as follows: in the indication mode of the “Current time of day” parameter, press and release the “START” key and on the sixth time signal the “H” key is pressed, while the digits of minutes and seconds are reset to zero. If the value of the "Current time of day" parameter coincides with the set value of the alarm clock, three melodic sound signals are emitted with a duration of 30 s each with a period of 1 min. Resetting the alarm clock setting is carried out as follows: in the “Alarm” parameter display mode, press and release the “START” key and then press the “H” key. In this case, the symbols “” appear in the digital digits, and the “bell” symbol is absent in the display mode of the “Current time of day” parameter.

3.3 Clock drift correction

To reduce the error of the watch, it is possible to introduce a correction factor. To do this, in the “Current time of day” parameter display mode, press and hold the “START” key for 2 s - the “C” symbol and the flashing value of the correction factor will appear on the indicator. Use the "+" or "-" keys to enter the required value of the coefficient and, by pressing the "START" key, exit the correction mode. Are the maximum values \u200b\u200bof the correction factor equal? 31. One unit of the correction factor is equal to the change in the clock rate by 0.35 s per day for positive values \u200b\u200band 0.18 s per day for negative values.

3.4 Setting the speed limit

The entry into the mode of setting the maximum speed is made by pressing the "START" key in the indication mode of the "Average travel speed" parameter. In this case, a blinking value of the maximum speed appears on the indicator, when exceeded, a warning sound signal is generated. Changing the value of the maximum speed is carried out using the "+" or "-" keys with a step of 5 km / h from 20 to 200 km / h. The exit from the installation mode is made by pressing the "START" key.

3.5 Operating modes of indicator backlight

When the instrument lighting is on, the backlight level is adjusted with the backlight control on the vehicle instrument scale. When the instrument lighting is off and the ignition is on, the backlight level is adjusted in the following sequence: in the “Total travel time” parameter display mode, press and release the “START” button. In this case, all single segments (icons) will be displayed on the indicator, which is a sign of the backlight level adjustment mode, and the number corresponding to the backlight level as a percentage of the maximum value will be displayed in digital digits. Use the "+" or "-" keys to set the required backlight level. Each time you press the keys, the backlight level changes by 5%. If the keys are held for more than 0.5 s, the autorepeat mode is activated. The set backlight level is retained until the next correction. To exit the adjustment mode, press the "START" key.

3.6 Setting the fuel level

Setting the fuel level table

The computer memory contains tables of FLS readings with a discreteness of 3 liters (the fuel level values \u200b\u200bat intermediate points are calculated by interpolation). Depending on the type of vehicle and the type of instrument cluster installed on the vehicle, one of the fuel level tables stored in the computer memory must be installed for correct readings of the fuel level in the tank by the computer. Electromechanical instrument combinations can be installed on the car - they form an output signal of the fuel level with a maximum voltage of more than 5 V, or electronic instrument combinations that generate an output signal of the fuel level with a maximum voltage of up to 5 V (a distinctive feature of these instrument combinations is the presence of a liquid crystal odometer indicator) ... The procedure for setting the type of instrument cluster and the corresponding fuel level table is as follows:

a) disconnect the "Battery" circuit (remove the "-" terminal of the battery or disconnect the harness connector from the computer);

b) press one of the following keys to select the type of instrument cluster: - "L" instrument cluster of electromechanical type; - "L / 100" - electronic type instrument cluster; - "KM" instrument cluster of the GAZ-3110 car;

c) while holding the selected key, connect the "Battery" circuit (connect the harness connector to the computer) and after a time interval of 2 s release the key.

3.7 Calibrating the FLS

Due to the fact that the vehicle's FLS has a large technological spread of parameters, to increase the accuracy of the fuel level readings, the computer provides a mode for correcting the FLS readings table (calibration).

ATTENTION! BEFORE BEGINNING TARING, MAKE SURE THE FUEL LEVEL SIGNAL IS CORRECTLY CONNECTED TO THE COMPUTER AND SET THE CORRECT TYPE OF INSTRUMENT COMBINATION.

The calibration procedure can be carried out at the request of the owner independently.

1. To do this, it is necessary to drain the gasoline from the tank, leaving the minimum volume of fuel required for the operation of the gas pump (for VAZ cars it is 3 liters) - this volume is then taken as a zero level.
2. Then enter the indication mode of the "Fuel level in the tank" parameter, press and hold the "START" key for 2 s, and a blinking number "0" will appear on the indicator.
3. Press and hold the "L" key for 1 s until a sound signal appears to confirm memorization of information. After that, the indicator will show a blinking number "3".
4. Pour 3 liters of gasoline into the gas tank using a measuring container, wait the time required to set a constant fuel level, press and hold the "L" key for 1 s until a confirmation beep appears. The indicator will show a blinking number "6".
5. Further, to continue taring, it is necessary to repeat the above procedure, each time adding 3 liters and then pressing the "L" key. In this case, it is necessary to ensure that the total amount of fuel in the tank corresponds to the value on the indicator for a particular calibration stage.
6. To end the calibration mode after recording the last value of the fuel level, press the "START" button, turn the ignition off and on.

Note - The maximum possible value of the fuel level during calibration is 72 liters.
