What should the sensor readings be when diagnosing viburnum?

Lada Kalina is already equipped from the factory with a special on-board computer mounted directly into the instrument panel. Thanks to this, you can react as quickly as possible and diagnose the problem that has arisen. There is a self-diagnosis mode for this. Unless the previous owner was motivated by selfish goals and “turned out” these light bulbs, in which case they need to be replaced.

The video shows entering the diagnostic mode of the on-board computer on the Lada Kalina:

Errors are shown as a digital code and in this article we will tell you how to read them correctly and make the right decision.

Programs for OBD-II adapters for mobile devices

As promised earlier, here is a list of popular mobile applications for reading data from car ECUs:

• It is considered the most common program for computer diagnostics of cars for mobile devices running iOS and Android. The application is paid, but there is also a free version with reduced functionality.
• This mobile application for Android was developed by Palmer, the owner of the copyright for the previously discussed ScanXL program for Windows. The application is paid. A free, stripped-down version is available.
• Car Gauge and Car Diagnostic. Free and paid (respectively) versions of the program for ELM237 adapters with the ability to connect modules (only in the paid version) for diagnosing Ford, Nissan, GM, Toyota and KIA cars. Available for Android devices.
• Car Doctor. A simple free program for Android that allows you to read errors and operating parameters of vehicle systems that support ODB-II.

These are not all existing programs for ODB-II adapters for mobile devices.

Engine control unit Lada Kalina

The capabilities of autodiagnostics depend on the type and brand of the ECU (electronic control unit, ECU). The type of ECU depends on the year of manufacture of the car and the engine (environmental friendliness and engine number).

On Kalina 1, 2 cars the following are most often installed:

The ECU of the Lada Kalina is located under the central panel, and in order to view the number and type of the ECU, the ECU should be removed (lift the panel).

Engine control units, in turn, have a certain firmware, but for diagnostics via the OBD2 connector, only the presence of a CAN bus is affected. If you have CAN, you must select an appropriate diagnostic adapter that supports this protocol.

IMPORTANT: If ECUs without CAN bus support are installed, you must use the KKL VAG adapter.

It is recommended to carry out ECU diagnostics once every 10,000 km, or every maintenance. The example shows a Bosch unit with firmware b173CR03 (serial firmware) without CAN.

Briefly about ECU firmware:

Flashing (reflashing) the Bosch Me17.9.7 control unit on VAZ cars is only possible using a K-Line adapter, which supports data transfer via the corresponding bus.

ECU firmware for Lada Kalina - optimizing vehicle performance

All domestic car enthusiasts can be roughly classified into 2 types: those who want to buy a foreign car and save money for a long time for this. And those who buy a domestic car and then spend a certain amount on modifications or modernization of the car. Of course, if a person is satisfied with the operation of the machine, then there is no need to modernize it. However, as practice shows, the majority of car owners, and specifically the Lada Kalina brand, are still dissatisfied with the performance of some car parts. To solve this problem, there are several options, one of which is car chip tuning.

The most common error codes

They consist of 5 characters. Each brand of car has its own, the most common of them are associated with damage to the electrical circuit, disturbances in the removal of exhaust gases, failure of the sensors themselves, problems with voltage in the on-board network or with the speed of the car.

If previously a car was repaired “at random”, relying only on the skill of a car mechanic at a service station and the uncharacteristic sound of the car, now almost any car enthusiast, if desired and with the necessary equipment, can diagnose his car himself, identify the car’s fault with his own hands and fix it. You can also entrust this to professionals.

Detailed video instructions will help you correctly diagnose your car.

How to find out which ecu is on Kalina

New model of AvtoVAZ

In 2004, the VAZ automobile concern released a new car, the Lada Kalina. And in 2013, after 9 years, the production of the first generation Lada models ceased. AvtoVAZ launched new improved and modified Lada Kalina cars.

Despite the fact that this brand is getting better and better every year in terms of its characteristics, car owners are still trying to modernize their vehicle: they do tuning of the chassis and appearance, chip tuning of the engine, in other words - Lada Kalina firmware, add various accessories.

What are standard parameters

Each engine has its own standard parameters. These are technical characteristics that determine the normal operation of the motor. These parameters are compared with the values ​​obtained during diagnostics. All measurements are carried out with the engine running at idle speed.

The presence of errors that are stored in the car's memory is the so-called DTC parameter. What these errors are can be determined by deciphering their codes, which can be easily found on any resource on the Internet. There are entire tables with interpretations of error codes.

General characteristics of the model

In the new generation of Kalina, torque has increased and an adjustable intake has appeared. The engine has become softer and smoother. But the main difference of the new Kalina is that it now complies with the Euro-4 class.

The car is still a 5-door and 5-seater, the rear seats fold down to increase luggage space. The shape of the car has become more streamlined, its external data is much better than that of the previous version. Thanks to the modernized body shape, the car began to behave much more confidently on the road. The vehicle's ground clearance has also increased noticeably.

Like the old Kalina, the new one is available in 2 versions: station wagon and hatchback. Engine 8- and 16-valve 1.6 liters. The suspension was developed jointly with the designers of Renault and Nissan, and the automatic transmission was borrowed from the Japanese.

In general, no matter how good the new Lada Kalina is, firmware for its engine will not hurt. And the point is not a lack of confidence in the quality of products produced by domestic automakers, but the desire of car enthusiasts to adapt the car to their needs as much as possible.

What is the difference between chip tuning and tuning?

Tuning is translated from English as “adjustment” or “tuning” and means work to improve the technical characteristics of a car. It includes the modernization of all engine systems and its tuning: improving the characteristics of the intake system, refining the valve timing, reducing fuel requirements, etc. Other components of the car, such as the gearbox, intake and exhaust systems, suspension and braking system, can also undergo tuning. All this is done with the aim of adapting the machine to certain operating conditions.

Chip tuning is a modification of the car's microprocessor. Since in the modern world it is impossible to imagine any technology without electronics, and under the hood of the car there is now a whole system of microcircuits that control all the main components of the Lada Kalina. It turns out that regular tuning changes the part itself and its characteristics, while chip tuning is the central control of this part.

I would like to say right away that the firmware of a car’s electronics can be easily combined with conventional tuning, and in some cases it is simply necessary. Having replaced a part and improved its characteristics, it is necessary to adjust its control so that the “brain” sends the correct commands to the unit.

Device for flashing a car

Chip tuning of a car not only improves performance, but also, as a result, saves money for the owner. After upgrading the engine, fuel consumption is significantly reduced, which leads to lower gasoline costs, and also extends the life of all units. Due to this, you can save on constant repair services.

Car firmware is considered the most cost-effective intervention that does not require penetration into the internal combustion engine system itself.

Accurate and competent work of a specialist makes changes that cannot be ignored during the operation of Kalina. She becomes more flexible in management. Inexplicable delays and “pecks” when pressing the gas pedal during acceleration disappear. You can forget about unpleasant twitching while changing speed.

The best inexpensive amateur car scanners

Strictly speaking, the name ELM327, used by numerous Chinese manufacturers for their cheap diagnostic devices, is illegitimate - this designation belongs to a specific American company that first developed an interface for converting various automotive communication protocols into a set of standard serial port commands, devices common on the market are its unlicensed copies.

Depending on the hardware implementation, the Chinese interface can have both a USB connection (such a device is recognized in the system as a virtual COM port) and a Bluetooth wireless interface. Recently, devices with a WiFi module have become widespread, but despite active advertising promising high data transfer speeds, in reality they are less functional6 most programs are designed specifically for virtual COM ports implemented via USB or Bluetooth.

The popularity of Chinese clones of the ELM327 car scanner is ensured not only by the low price, but also by the prevalence of free, cheap or hacked programs for various platforms: smartphone owners usually use Torque, for owners of domestic cars there is a regularly updated OpenDiag program (one of the few cases when the ELM327 can really be used for serious diagnostics).

• The most affordable price of all diagnostic devices.
• Availability of programs for Windows, Android and iOS.
• Most models are compact and have a wireless connection.

• The efficiency of the scanner depends on the software used to communicate with the ELM327, the vast majority of which are amateur-level programs.
• It cannot be used for adaptations or recoding of control units; it “sees” a minimum of devices (usually only the injection controller).

Features of chip tuning

The main thing in firmware (chip tuning) is that the engine resources do not suffer at all, but on the contrary, they are preserved and expanded longer. Indeed, for many car owners this indicator is very significant, because the car, as a rule, is used every day, in an active rhythm, constantly wasting its resources. Because of this, the car ages, its characteristics become worse every year. And chip tuning slows down this process. Eliminating errors in the engine system preserves and extends its life.

In addition to improved engine performance, the firmware also affects the gearbox if it is automatic. Shifting becomes clearer and quicker, and all because in modern Lada Kalina cars the engine and automatic transmission are connected and considered one whole. While the engine is running, all information about its mode (torque, power) is sent to the transmission control unit, and the processor with microcircuits sends the automatic transmission system a command to shift gears higher or lower than the current one. Thus, the easier and faster the engine receives, processes and transmits information, the better the transmission will behave and the more comfortable the ride will be. At the same time, fuel consumption is reduced; it no longer has to be spent on unnecessary actions and commands. The result is money savings.

The procedure increases engine power

Particular attention should be paid to increasing engine power. True, not a single firmware program developer, and especially not a single chip tuning worker, can say with accuracy how much the car’s power will increase or has increased. However, the fact that this happens has been proven by many tests. Before flashing the firmware, the owner of the car is simply told how much the power will improve approximately - up to 15%. But sometimes the settings may not affect this engine performance indicator and only in rare cases reduce it slightly.

If under normal conditions, the greater the power, the greater the fuel consumption, but here the opposite is true: with increasing power, gasoline consumption decreases. This nonsense is only possible thanks to the firmware. And given the current cost of gasoline, the savings in fuel and money are very pleasing.

Troubleshooting methods

Now that all the causes have been identified, we can begin to consider troubleshooting. But, before we begin, it is worth noting that a car enthusiast needs to have an idea of ​​the design features of the engine if he wants to fix the problem himself. Otherwise, go directly to a car service center, in order to avoid other problems that, due to lack of experience, car enthusiasts usually create for themselves.

Sensors

Often, the reason why the check light on Kalina may come on is the failure of one of the sensors. Possible ones that are worth checking right away include: mass air flow sensor, idle speed control, crankshaft position sensor, oxygen sensor and coolant temperature sensor.

But, there is a simpler and more effective way to determine the malfunction of a particular sensor, namely connecting to the electronic engine control unit. Here you can look at the errors and, by deciphering them, determine where the problem is.

Throttle

A clogged throttle valve can often cause the check engine light to come on because not enough air is supplied to the power unit. The solution to the problem is cleaning. This process can be carried out using carburetor cleaning fluid or VD-40 fluid.

The part is removed from the car and cleaned, after which it is installed in place. It is also recommended to check the throttle position sensor, which may have failed.

Injectors

One of the common reasons for the “check” icon to appear on the dashboard is a malfunction of one or more injectors that do not spray the fuel mixture properly. So, it is worth dismantling all the elements and checking them using a special stand.

If there is none, then you can use the traditional method by pouring flushing fluid into the fuel supply pipes and activating the injectors using the battery. This way it will be clear which injector is not working well. But, experienced auto mechanics recommend cleaning and checking the nozzles on a stand, since the effectiveness of the procedure is higher.

Fuel pump and filter

Another cause of the malfunction may be a malfunction of the gasoline pump or its filter. Lack of power or contamination of the filter elements leads to the fact that an insufficient amount of fuel will enter the power unit to form an air-fuel mixture.

The malfunction can be cured by checking the functionality of the gasoline pump, as well as by replacing the filter inside the gasoline pump. It is also worth looking at the fuel filter, which could become clogged when pouring low-quality gasoline.

Air filter

A clogged air filter can cause insufficient air in the combustion chambers. So, to check this element, it must be dismantled, which is done quite simply. By inspecting the filter element, you can find out how dirty it is and whether the product needs to be replaced. So, after replacement, the check signal from the dashboard may disappear.

Spark plugs and high voltage wires

Wiring is also often the reason why the check icon lights up on the panel. This happens when the spark plug is inoperative or there is a breakdown in one of the high-voltage wires.

And another question, in order for this dashboard to work correctly on Kalina Cross, do I need firmware 2192-50 1.2? The photo shows what it is like now. Now my low beam and high beam are not working at the same time, and the emergency lights are not working properly.

Is it the same with two screens? Why connect to the power supply when you can rearrange the jumpers, what is the difference?

I flashed grants for the tidy, everything works except for the backlight, that is, the screen lights up but where the arrows are there are no numbers, if you do a test of the tidy, everything lights up

Hello, I ordered USBDM v-4.95, but the Chinese sent USBDM-jb16-001, not USBDM-js16-001. Will it be possible to flash the KALINA 2 tidy and what needs to be done. THANK YOU.

I have USBDM-jb16-001. Still doesn't want to sew. It just doesn’t select the firmware, it gives an error

I was wrong, 076 without soldering, what version can I flash to?

I was wrong, 076 without soldering, what version can I flash to?

Thanks for the article and the used firmware! I edited the mileage, flashed the tidy from Granta Lux and put it in Kalina!

Please tell me how to solve the problem? I had a Grant standard 076 tidy, then a friend fitted me with a Datsun on-do Dream2 tidy. The price and white illumination of the scales captivated me. Shows TOZH, travel time, and everything else. The problem is that the warning lights (!), (ABS), (ESP) are constantly on, so these systems are not included in my configuration. I'm not good at electrics. Some advise reflashing the device, others say that the problem can be solved in 5 minutes using a programmer. What needs to be done to keep the warning lights off? I bought the programmer on Alika.

I don’t think it’s relevant anymore, but still. you need to reset the device. because this abs data is recorded when the device is connected to the car. I did that, everything is fine

Yes that's right. The problem has already been solved. Nevertheless thank you.

I don’t think it’s relevant anymore, but still. you need to reset the device. because this abs data is recorded when the device is connected to the car. I did that, everything is fine

can you tell me how to reset the device?

You need to do everything as written in the article above. Select EraseSelective and check the box. (if you want to reset the mileage and erase the immo, use EraseMass or erase all)

Have you encountered a problem where the outside air temperature is not shown in the instrument panel? Even after installing the sensor, the values ​​are not displayed on the screen. To correct this drawback, it is proposed to update the dashboard firmware of Lada Granta and Kalina 2 cars.

First, we find out what version of the firmware is embedded in the instrument panel. The first numbers (2190 or 2192) indicate the car model (Granta or Kalina 2). This is followed by the numbers 00, 20 or 40, which stand for “standard”, “norm” or “lux”, respectively.

Firmware for Lada Kalina

Chip specialist at work

Popularly, the on-board computer responsible for the electronic control of vehicle systems is called the “brains”. The software on different machine models may differ, so the same motors may operate differently.

Special programs for firmware are developed by specialists and produced by well-known companies. Auto repair shops involved in engine tuning usually purchase official software with all license agreements and technical support rights. In addition, the workshop must have special equipment for reprogramming the car.

The firmware software becomes obsolete and is updated, with more advanced versions being released. So, for Kalina cars, version 3 of the firmware only recently appeared. It adds even more dynamics to the car and reduces the loss of engine power when the air conditioning is on.

After flashing the car, the driver of the Lada Kalina feels changes in the operation of the vehicle:

Return to contents

Decoding combinations

Errors read on the standard panel of the on-board computer can be deciphered using the table. It is useful to print out such information and carry it with you in the glove box, since breakdown of car sensors can happen on the road. Many problems can be corrected only during repair work in a car service center. Knowledge of the decoding will allow the owner to control the process of repairing his car.

Self-diagnosis codes

When diagnosing, you can read the fault codes listed in the table from the instrument panel. Please note that several errors may be displayed simultaneously during the verification process.

Below is a complete list of self-diagnosis errors.

Controller errors

For more complete diagnostics, the car needs to be checked with a KKL VAG-COM for 409.1 scanner. To do this, you need the scanner itself and a laptop with the pre-installed Diagnostic Tool v. 1.3.1., which allows you to view all the vehicle’s operating parameters and find out possible problems. Error codes received by such devices will consist of four numbers and a letter located in front of the numbers.

It should be remembered that each letter is responsible for a certain part of the machine components:

• B - indicates errors in the electronic components of the car body (window lifters, microclimate);
• C - errors in chassis components (power steering);
• P - malfunctions in the engine or automatic transmission control systems.

The video, shot by the author of CompsMaster, clearly demonstrates the connection of a test laptop to the diagnostic connector and shows the functionality of the program.

Another way to control the ECM is the additional on-board computer State, which is connected directly to the diagnostic connector and installed on the center console. This device is capable of reading almost all operating parameters of various vehicle systems. There are several types of State computers, which are selected according to the model of the ECM unit.

Basic mistakes

The table below summarizes the main error codes for Kalina category “P” without taking into account the letter prefix.

Firmware software

After the firmware the machine will work better

The only caveat to the firmware of the “brains” of the car: if the vehicle is under warranty, it automatically becomes invalid. This is due to outside interference in the operation of the engine, for which the manufacturer is not responsible. Therefore, if something happens to the motor, you can no longer hope for warranty service.

Modern firmware (chip tuning) experts offer 3 main software options for the Lada Kalina, although in fact there are more of them. The programs are supplied by both Russian and foreign developers. The most commonly used systems are “Paulus”, “Icebreaker” and “Adakt”. They are most in demand in our country and are products of domestic manufacturers, so they are perfect for the Russian Lada Kalina car.

Masters can offer either a specific program or all 3. Sometimes experts offer to try several programs at once and choose the one you like, the most optimal. For example, once every 2-3 days they install new firmware and test the car, evaluating the work. The firmware procedure itself takes no more than 30 minutes, and the cost varies from 1.5 to 5 thousand. Some experts offer testing of different systems as a promotion with special conditions.

Spent spark plugs and worn high-voltage wires

Candles have a direct impact on the quality of the combustion process of the mixture inside the working chambers of the engine. A failed spark plug is unable to generate the spark needed to ignite. This results in unburned fuel and air entering the exhaust manifold. Even if the engine managed to start, a misfire will cause it to operate incorrectly, characterized by vibration, jolts, failures during acceleration, etc.

Experts rightly put forward recommendations for replacing the specified elements of the ignition system every 25-30 thousand km. If the quality indicators of the fuel being refilled are far from the required level, then the replacement frequency should be reduced.

The main signs of candle failure are as follows:

• difficulty starting the engine;
• increasing the level of fuel consumption;
• incorrect operation of the unit not only at idle, but also at high speeds with the presence of side symptoms (dips, twitching, etc.).

Also, worn-out spark plugs, as noted earlier, can provoke rapid failure of the converter, so the timeliness of their replacement is one of the main conditions for the viability of this element of the exhaust circuit.

The owner of Lada Kalina 2 needs special attention to high-voltage cables and their tips installed directly on the spark plugs. The main test method is to measure resistance. Here you will need to involve a tester. The value of the required resistance can be found in any Lada Kalina service manual. If this indicator diverges from the standard value, then such a cable must be replaced.

There are also many other reasons why the check light is on. Sometimes these factors are not “intimidating” in nature, and the method of eliminating the problem identified in the process of diagnosing the problem is cheap in terms of costs. But there are also serious breakdowns, the elimination of which requires the intervention of significantly greater human and financial resources.

A flashing “Check” symbol in a Lada Kalina 2 car indicates that the driver needs to stop immediately to check the oil level in the engine (wait a few minutes first). Sometimes the unit's lubrication circuit filter may become unusable. A useful step here would be to inspect the engine for visible damage.

Pinout of diagnostic connector VAZ 2114

Pinout and where is the diagnostic connector for VAZ-2112

Diagnostics of modern car models is carried out using a special diagnostic connector. It connects to a computer, which analyzes the current state of the vehicle, determines the malfunction and indicates it. If you have the appropriate equipment, you can look for breakdowns even at home. However, not all VAZ-2112 owners can find the diagnostic connector right away. Today we’ll talk about its location on the classic panel and on the Europanel. In which part of the car should I look for the required socket?

Where to look for the connector

It is important to know that on different cars the required socket is located in different parts of the car. Moreover, on some AvtoVAZ models it may be in a completely different place compared to another car

Let's look at several VAZ cars as an example:

• on the VAZ-2112, as well as on the 2110, as well as 2111, the socket is located to the right of the driver’s seat, immediately under the column;
• on models 2108, 2109 and 21099, the socket you need is located under the glove compartment, on a special shelf;
• on cars with a europanel it can be found in the center of the console, near the cigarette lighter. A special decorative cover is used to disguise it;
• on Lada Kalina cars, the connector can be found near the gear shift lever. As is the case with cars with a Europanel, it is hidden under a special cover;
• on a Priora you need to look for it right behind the glove compartment, on the wall.

Thus, on the VAZ-2112 the diagnostic connector is located on the right side of the driver’s seat. It is located immediately under the steering column and, in principle, is not so difficult to find. Inspect the bottom of the panel.

Pinout

Knowledge of pinouts may be required if a car enthusiast wants to make an adapter for computer diagnostics with his own hands, or if you need to connect without one. Experts recommend buying ready-made devices without the need to make a plug yourself. However, if you do not have such an opportunity, and diagnostics need to be carried out urgently, we will consider two main pinout options used on VAZ cars of various years of manufacture. Until 2002, AvtoVAZ products used the following pinout option:

1. The 4th and 5th pins are GND outputs.
2. Pin 16 – +12 V (power line).
3. The 7th contact is the diagnostic line itself.

Since 2002, the pinout scheme has changed significantly. Now it looks like this:

1. Pin H – +12 V (power line).
2. Contact G – +12 V for the fuel pump.
3. Pin A – GND output.
4. Contact M – diagnostic line.

There is one important note to note regarding this diagram. If you connect the connector without a block, but directly, it is recommended to use the charge from the cigarette lighter as a source of electricity

The peculiarity of this pinout is that contact H is not always routed in the car. The use of G is also not recommended because high frequency current is supplied. This can have a negative impact on the adapter, even to the point of burning it out. However, cases of burning out the fuel pump connector are quite rare. Therefore, if you wish, you can also use this option.

As you can see, the pinout on VAZ cars of different ages is sometimes very different. Therefore, we advise you to look at the registration certificate of your car and find out what year it is made. On older vehicles you will not find the new pinout design as it did not exist yet and on newer vehicles the old design was no longer used.

Pinout of diagnostic connectors for VAZ and GAZ cars

Currently, the vast majority of cars have an OBD2 diagnostic connector (trapezoidal 16-pin block, usually located in the steering wheel area). Through this connector you can connect diagnostic equipment to diagnose your car, as well as connect on-board computers and other devices that work through the diagnostic connector.

People often have questions about the pinout of diagnostic blocks for some cars. In our store there are various adapters for different models. But if you forgot to order an adapter for your car, you can try to make it yourself, or connect the adapter directly. To do this, we have prepared for you a short review on the pinout of the OBD2 socket, the pinout of the sockets for VAZ and GAZ cars.

Chip tuning of the multimedia system

If we talk about the firmware of all electronic systems of the Lada Kalina, then we should not forget about multimedia, which can also be subject to tuning. The Lada Kalina MMC firmware is updated to change the appearance of the menu and expand its capabilities. It differs from working with an engine in that it can be done independently at home.

In this case, you will need an SDHC memory card and special software on your computer, which must be transferred to this flash drive in unzipped form. Then, following the instructions for flashing the MMC (usually they come with the program), perform all the necessary steps in sequence.

What can be obtained as a result of modernization:

It is important that all changes made by software settings to the operation of the engine and MMC microcircuits can be easily canceled. To cancel engine firmware during operation, specialists save all initial parameters in a special reserve. If necessary, if the client is not satisfied with the result of the modernization, everything can be returned to its place in the same short time.

The car has long ceased to be a means of transportation. Cars now play a significant role in everyone's life. A person strives to improve the performance of his car, increase its productivity, improve quality and at the same time save money.

Diagnostics using third-party equipment

More precisely, errors on Chevy Niva can be identified by connecting additional equipment. The technique is more technically complex, but allows us to determine the cause of a breakdown or failure with minimal error. In this case, the sequence of actions is as follows:

• turn off the engine;
• find the contact connector under the dashboard, the connector is located at the bottom of the steering column;
• connect the configured computer to the ECU output;
• turn on the ignition;
• follow the program instructions.

If all actions are performed correctly, all available information and any errors in the form of encrypted codes will be displayed in the desktop window.

There are also specialized scanners designed specifically for Chevrolet NIVA. Dealer devices are connected to the place of the standard signaling unit through an output cable.

Separately, we should highlight modern devices designed to connect a smartphone to a car, while reading encodings and controlling operating modes occurs directly from the gadget’s display.

At the same time, you should know what the encodings displayed during diagnostics mean. The code consists of several elements.

First part:

• P – the motor electronics have failed;
• C – there are problems with the chassis;
• B – interior space, a problem has been detected;
• U – there are problems when establishing pairing of on-board systems.

The next element is a single digit:

• 0 – OBD 2;
• 1-2 – standard code of the manufacturer;
• 3 – reserve part of electrical equipment.

The following digit determines the exact serial number of the line in which the defect was detected:

• 0 – exhaust system device;
• 1-2 – violation of the fuel or air supply device to the engine;
• 3 – ignition does not work correctly;
• 4 – additional equipment control;
• 5 – monitoring the engine idle state;
• 7-8 – transmission and chassis design.
