How to remove a steering wheel with a cushion on a Priora: video - Sarterminal.ru

The main distinguishing feature of the Priora steering wheel is the presence of an airbag. That is, it has two electrical devices in its filling:

Horn switch.
Airbag kit.

Because of these difficulties, it was necessary to install a special drum with contact tape in it to turn on these devices.

Attention! Not all Prioras are equipped with an airbag, but in any case there is a cavity in the steering wheel for it.

Because of this feature of the Priora steering wheel, removing it requires great care.

Why change or remove it?

The car steering wheel itself is very durable. Therefore, steering wheel replacement is rarely required. But I have to shoot much more often. Replacement is usually done when tuning a car for a “sports” version. Accordingly, such a replacement is only one of the episodes in a complex of alterations.

And the removal of the Priora steering wheel must be carried out for repair and maintenance of electrical components.

Step-by-step instruction

1. On the inside of the steering wheel, unscrew the two airbag mounting screws.

The screws are located on the right and left of the inside of the steering wheel.

2. Pry up the airbag and disconnect the power connector from it.

In order to disconnect the power connector, you need to use a flat-head screwdriver to pry it up and remove the latch. After releasing the latch, remove the connector upwards.

3. Disconnect the power connector from the horn buttons. We squeeze the ears and disconnect the connector.

4. Place the steering wheel so that the wheels point straight and make a mark on the steering wheel relative to the steering column casing. This must be done in order to set the steering wheel to its previous position.

The mark can be made with a washable marker.

5. Unscrew the nut securing the steering wheel to the shaft using a twenty-four socket. Do not unscrew the nut completely.

After unscrewing the nut a little, we knock the steering wheel off the splines. This can be done by striking movements of the palms of the hands on both sides of the steering wheel.

After the steering wheel has come off the splines, unscrew the nut completely and remove the steering wheel.

6. When removing the steering wheel, thread the airbag and horn power wires through the hole.

7. Now a few words about reverse installation.

We thread the power supply wires for the pillow and the signal.

We put the steering wheel on the splines and do not forget to align the marks that you made.

8. Screw in and tighten the steering wheel mounting nut.

Tightening torque from 30-50 Nm.

9. Connect the signal power connector.

10. Take the airbag and connect the power connector. After connecting, close the latch.

11. Place the pillow in place and secure it with two screws on the back side.

How to remove a steering wheel with an airbag

On most Lada Priora cars, the steering wheel already comes with a built-in driver airbag, so when removing the steering wheel there are certain points that will need to be completed.

So, in order to remove the steering wheel on a Priora, we need the following tool:

24 mm head
Extension
Ratchet or crank
5 mm hexagon

Causes of airbag failure

The reason for the failure of the Lada Granta airbags is:

Triggered due to an accident.
Closure of the pillow package, which prevented it from opening, or a manufacturing defect.
Battery failure, which caused the airbags to deploy.
Wear of the pillow module.

Reasons for failure of the Lada Granta steering wheel:

Deformation of the structure due to the driver hitting the steering wheel.
Braid wear and cracks.
External factors that caused damage to the steering wheel.

All this becomes the reason for the forced replacement of the steering wheel and airbags.

Catalog numbers and steering wheel analogue options

It is generally accepted that only original spare parts for the steering wheel and airbags can be installed on the Lada Granta, but this is a misconception. There are several analogues of these parts, which are known only to tuning masters and some car enthusiasts.

Let's look at the catalog numbers and manufacturers of the Lada Granta steering wheel:

The original VAZ part has the manufacturer's catalog number - 21910-3402018-00. It fits perfectly and does not require any improvements or modifications.

Factory steering wheel

Catalog numbers and airbag manufacturers

Let's look at the catalog numbers and manufacturers of Lada Granta airbags:

The original spare part is produced by the VAZ plant. It consists of several elements that include: a gas generator module (21910-8232010-00) and a safety control unit (21900-3824010-00).

Airbag module

Airbag control unit

Thus, you can understand that in addition to standard parts for the steering wheel and airbags of the Lada Grant, there are also analogues that few people know about.

Photo report on removing the steering wheel yourself

First of all, read the material on removing the driver's airbag on a Priora. Then, when you have dealt with this, you can proceed further. Disconnect the power wires to the sound signal.

Then we put the head on 24 and rip off the nut, but don’t unscrew it completely yet. Before you start knocking it off the shaft, you need to mark the position of the steering wheel relative to the shaft - you can make marks on the steering wheel and casing.

When the nut is loosened, leave it on the shaft for now. Then we take and knock down the steering wheel from the reverse side, tapping it with medium force - on both sides.

When it comes off the splines, you can finally unscrew the nut and remove it from the shaft.

Carefully thread the horn power wires, as well as the airbag power wires, through a special hole.

And now the steering wheel is finally freed and you can remove it completely from the Priora.

If there is a need for replacement, then we perform it in the reverse order. Of course, the installation is carried out according to the marks that were originally set. The fastening nut must be tightened with a torque of 31 to 41 Nm. But you can take the average value and tighten it with a force of 40 Nm.

Removing the Airbag from the Smart steering wheel

Removing the airbag in Smart cars is carried out only by removing the steering wheel. Before proceeding with disassembly, you must disconnect the battery to prevent the Airbag from triggering.

Steering wheel of a Smart car with an airbag hidden under the front panel

Under the steering column cover on the bottom side there is a single bolt that needs to be unscrewed.
The steering wheel comes out with a little effort. Before you finally remove it, you need to disconnect two wires - they are connected to the AirBag and ESP sensors.
The removed steering wheel is placed on a flat surface “face down” to remove the plastic casing. It is secured with fixing clips.
After removing the panel, the attachment points for the rear and front panels are revealed. To dismantle the front panel, you will have to unhook three clips and bend the fixing elements.
Under the front plastic panel of the steering wheel there are contacts for the “horn”.
The airbag is removed after unscrewing two bolts from the back.
In addition to the Airbag itself, inside the steering wheel there is a cartridge with wires, two of which are connected to the airbag, two to the ESP. It is advisable to disconnect the yellow Airbag connector.

How to remove the steering wheel on a Lada Priora with an airbag yourself

The above installation features with a built-in airbag force you to be especially careful when understanding the process of how to remove the steering wheel on a Priora. Experts advise that to carry out such work you must have the following tools:

socket head for a 24 mm wrench;
ratchet or crank;
thin flat-blade screwdriver;
extension;
5mm hexagon socket.

Cases when replacement of the SNPB is mandatory

Most system components are disposable and must be replaced in the following cases:

triggered as a result of an accident or other incident;
in cases of damage to the components of the airbag system;
after ten years from the date of production of the airbag modules and pre-tensioning device (the production date is marked on the module body).

Precautions and preparations

"Attention! Incorrect installation or dismantling of airbag components can lead to premature deployment of airbags and disruptions in the operation of the system as a whole. The results of mistakes made may be: damage to the life or health of the driver and passengers.”

Removal sequence

First you need to unscrew two screws on the back of the Priora steering wheel, which are located on both sides. To do this, you will need a 5 mm hexagon, while on both sides it is necessary to compress the spring clamps, preventing the pillow from falling out. It is important to remember that before starting work, you must remove the battery terminals to prevent the airbag from deploying.

After this, carefully remove the cushion from the front of the steering wheel. To do this, you need to carefully pry the clamp together with the wires and move it to the side, and also disconnect the power wires leading to the sound signal.

Please note that disassembling the airbag module is strictly prohibited.

Next, a pre-prepared 24-millimeter socket will come in handy, with the help of which the shaft nut is torn off; however, there is no need to unscrew it completely yet. At this stage, you need to somehow mark the position of the steering wheel, which will be needed for subsequent assembly to its original position. For this purpose, you can make appropriate marks on the casing or, in fact, on the steering wheel.

Once the nut has been loosened, you can begin to directly remove the steering wheel. To do this, you first need to gently tap it from the back with careful movements on both sides, but you should not use excessive force, because the steering wheel is still on the shaft. By progressively pushing the steering wheel, it is necessary to ensure that it is completely dislodged from the splines, and when this can be achieved, you can further unscrew the previously loosened nut.

After this, you can actually start removing the steering wheel. You need to act as before, carefully, threading the power wires for the horn and airbags through special holes. Upon completion of this procedure, you can finally remove the Lada Priora steering wheel.

After carrying out the planned actions, assembling the Lada Priora steering wheel with airbags is carried out in the reverse order. At the same time, do not forget about the marks made during disassembly, which will allow you to install the steering wheel in its original position. Remember that when carrying out the above manipulations, before removing the pillow, you should be outside the zone of its deployment.

Subsequently, after the integrity of the steering wheel and airbag has been restored, when you first remove the lock and turn on the engine, it is recommended to be outside the car and turn on the ignition by extending your hand over the steering column. This way you can protect yourself from unexpected operations and injury.

To summarize, it can be noted that in general, the process of removing the steering wheel of a Lada Priora car with an airbag, subject to all the above recommendations, does not pose any particular problems, especially for experienced car enthusiasts, and can be done independently, without contacting service centers of manufacturers or dealers, as well as at a service station. The main thing is to follow the procedure step by step and take precautions.

Removing the driver's airbag module

Set the front wheels to the straight ahead position of the vehicle.

The upper spokes of the steering wheel should be in a horizontal position.

Open the left front door.

Being outside the car, on the side of the steering wheel, turn the steering wheel 180 degrees and unscrew the right bolt, Figure 2, securing the gas generator module to the steering wheel.

Airbag and steering wheel replacement Priora

Not all drivers know how to properly install the Priora steering pad and how to install a new steering wheel. Of course, this work can always be entrusted to car service specialists, but sometimes there is no money for such services. When trying to replace a part on their own, many users encounter various difficulties. In fact, the installation and dismantling process is quite simple if you follow the step-by-step instructions.

Tools for work

Let's try to figure this issue out together. Experts say that you can remove it on your own, without involving professionals from a car service center and making do with a small list of tools.

All these tools will help you easily cope with removing the steering wheel yourself. If you use them correctly, the whole process will seem easy.

Safety system

The Lada Priora has a built-in safety system that is activated in the event of a collision. This system is represented by an inflatable soft pillow that expands at the time of an accident. The Priora has 4 airbags: one for each passenger, including the driver. They operate only in the event of a sharp collision at a speed of over 20 km/h, so they never open accidentally.

The driver's airbag is located directly in the Priora's steering wheel, which can cause some difficulties when trying to remove or replace the steering wheel or its elements. If you are going to install a new steering wheel, then it is worth finding out a little about the features of the location of the cushion.

The design itself is quite simple and consists of the following elements:

gas generator;
pillows;
control module.

In the event of a collision, a special sensor sends a signal to the module, which, in turn, turns on the gas generator. In about a second, the device fills an empty bag with nitrogen, which unfolds towards the driver.

If you bought a used Priora, check for the airbag: press just below the center of the steering wheel. A soft-touch center means the cushion is in place.

Operating principle

The airbag of any car is a gas generator that is activated when a signal is received from the electronic control unit (ECU). The AirBag has a squib inserted into it. He is able to deploy a special bag and fill it with nitrogen in a matter of seconds. The control unit reads data from sensors that control the speed of movement, direction and force of impact. The airbag will not deploy at speeds below 20 km/h or at light impacts.

AirBag is a gas generator that inflates the bag with nitrogen based on a signal from the electronic control unit

Replacing the steering wheel

The standard Priora steering wheel can be replaced with a new model from the Priora 2 SE luxury. The differences in feel are quite significant. The updated model is much more convenient to use, so it’s worth considering such a purchase if you have an old, battered steering wheel installed.

We will now figure out how to remove the steering wheel. To replace you will need the following set of tools:

Phillips and flat screwdriver;
hex key five;
replaceable head for 24 and 8;
ratchet.

Here's the procedure:

Disconnect the device from the battery by removing the terminal. We are waiting for the capacitor of the protective system to discharge.
We fix the steering wheel in the position for driving in a straight line.
Using a Phillips screwdriver, unscrew the fastenings of the steering wheel casing (7 pcs.), then remove it.
Next, you will need a hex wrench to unscrew the next 2 steering wheel airbag mounts.
Now we pull the pillow towards us, use a flat screwdriver to pry the device from the bottom on the other side and disconnect it.
Using a 24mm replaceable socket, loosen the fastening of the steering wheel to the shaft. The nut is strong, so you may have to work hard. Unscrew and remove the steering wheel.
The 8 socket is useful for removing the steering column cable and switches.

Restyling

The smooth droplets of the steering column switches no longer stand out visually – the new style suits the car just right. Along with many little things that appeared in the cabin, the Priora 2 steering wheel with a chrome-plated Lada nameplate fits perfectly into the interior.

The diameter of the steering wheel has not changed at all, but the thickness has decreased. Steering has become easier because when a person tries to grasp a wide object with his palm, his wrist and forearm become very tense - it turns out that while driving, the hand is constantly under even more tension than it should be, and gets tired faster.

Steering wheel assembly

After the old steering wheel has been removed, we install a new model. Of course, you can limit yourself to general provisions: carry out the assembly in the reverse order. But there are several nuances that should not be missed.

We arm ourselves with the same tools and begin assembly.

If everything is installed correctly, the mechanism will not jam and will work fully properly for a very long time. The entire replacement process will take you about 40 minutes if you look at the instructions.

Difficulties in replacement

Removing the steering wheel on a Priora is quite simple, but putting everything back in place is not always possible.

Many users often have questions when replacing an old steering wheel with a new one. Here are the answers to the most common ones.

Question 1: Are mounts suitable for different models?

Answer: The mounts are identical, so the Priora 2 SE steering wheel is recommended for use on older models as well.

Question 2: I removed the steering wheel, but now I can’t put the new one back, it doesn’t work manually, what should I do?

Answer: If the part has been dismantled, then it can also be installed back. The steering wheel is installed by pressing your hands towards the shaft, without using tools like a hammer, but everything may not work out on the first try. There is no need to make sharp pushes of the steering wheel; a simple smooth press will be enough.

Question 3: Are additional components needed for the mechanism besides the steering wheel?

Answer: Yes, you still need to purchase a steering cable of the same model. Its installation is carried out similarly to the old version.

Question 4: The steering wheel is stuck after installation, what should I do?

Answer: Most likely, the steering cable is installed incorrectly. Disassemble the structure and reassemble it, adjusting the position of the cable in advance.

AirBag fired: repair or replacement

After the passive safety system is activated, the airbags and sensors must be replaced. The AirBag cannot be repaired. The cost of such a replacement is high because the elements are supplied only assembled. Not everyone can afford to buy new spare parts. Therefore, car owners often turn to a car interior reupholstery workshop. The company's specialists restore the steering wheel trim and panel. This method is cheaper, but the safety of vehicle operation is reduced several times. The choice is up to the car owner.

The front panel and steering pad of the car before restoration

Panel and trim after work to restore integrity

It is not difficult to remove the airbag on a Lada Priora or Toyota Corolla with your own hands. You don't need a special tool for this. But problems may arise with the Smart baby. Also remember that the pillow cannot be repaired. You can restore the plastic cover or install a dummy plug that does not contain a gas generator with a squib. This approach will return the interior to a presentable appearance and save a considerable amount, but will reduce safety when driving a car.

How to remove the steering wheel of a Lada Priora

How many catchphrases are associated with this detail. And all of them clearly indicate the special role of the steering wheel in a car. Indeed, it is the steering wheel that transmits the driver’s effort to the car’s control system and corrects its movement. Unlike the steering wheels of the first models of passenger cars, the modern steering wheel is a comfortable and pleasant device, even to the touch. But it needs to be changed sometimes. How to do this on Priora?

Life hack: Steering wheel on a Priora - size, price, malfunctions

In a Priora car, the steering wheel comes in two types: a 4-spoke pre-restyling one and a three-spoke restyled one. In addition, you can install a multifunction steering wheel from Vesta on the Priora. The steering wheel of a Lada Priora car is rarely removed - for work in the cabin to soundproof the panel, replace the electric booster, and when the steering wheel itself is changed. You can remove it in 7 simple steps described below in this article! The price for the Priora 2 steering wheel is different from the first version, a little more expensive. The diameter is the same. In order to make the steering wheel thicker, a braid is placed on it, and to enhance it, it is covered with leather.

What does the Priora steering wheel hide?

The main distinguishing feature of the Priora steering wheel is the presence of an airbag. That is, it has two electrical devices in its filling:

Horn switch.
Airbag kit.

Because of these difficulties, it was necessary to install a special drum with contact tape in it to turn on these devices.

Because of this feature of the Priora steering wheel, removing it requires great care.

Why change or remove it?

And the removal of the Priora steering wheel must be carried out for repair and maintenance of electrical components.

How to directly remove the Priora steering wheel

To remove this important part, you need to prepare some tools:

Flat head screwdriver;
Pliers;
wrench head 24;
hexagon number 5
Wrench with extension for head.

Removal process

After installing the Priora in the desired position, it is better to fix the wheels, and you can begin to remove them. First of all, the airbag is removed. Removing it is a very delicate job and must be carried out with special precautions. To begin with, it is better to turn off the power to the car. That is, disconnect the battery terminal. And only after that, unscrew the 2 hex bolts from the back of the steering wheel. Then, very carefully move the device to the side.

The airbag wire connector is secured with a special clamp that wedges the center of the connector. You need to carefully pry it off with a thin screwdriver and then carefully remove it. Then remove the connector from the pillow. Without making sudden movements, put the device aside so that it does not come under impact or a sharp push. Do not under any circumstances try to disassemble the pillow!

Further work will be simpler. Using pliers, carefully disconnect the wires going to the sound signal and move them to the side.

Steering wheel removal steps

So, as a rule, any work consists of certain stages. It is worth noting that this does not require special knowledge, only manual dexterity and accuracy are important. Now you need to start the actual procedure:

1. Disconnecting the wire from the negative terminal of the battery;
2. Installation of the steering wheel, the position of which will fully correspond to the movement of the car strictly in the forward direction;

After you have completed all the steps of removing the steering wheel, you probably realized that everything is actually simple and even a little funny, and most importantly, fast. As a rule, there is no need to warn you that before removing the steering wheel you need to prepare a new one. If you are new to this business, then know that the Priore comes with steering wheels of certain models, which means you must pay attention to this when choosing it.

Steering wheel braid, its sizes and manufacturers

The braid on the steering wheel makes the touch even more pleasant, and you don’t mind spending money on it, because in your favorite car you want to surround yourself with only the best things. On the Priora you can put on the braid yourself, or pull the braid on like a “case”. The cover will not completely cover the steering wheel, but it is easier to install and remove. There are a lot of manufacturers, and their products differ only in design, and the price starts at 700 rubles.

The leather braid on the Priora steering wheel will be installed in an hour and a half. The kit includes instructions and a needle. This braid will look very organic, emphasizing the central insert behind which the airbag is hidden. The price starts from 500 rubles.

Attention! Not all Prioras are equipped with an airbag, but in any case there is a cavity in the steering wheel for it.

Because of this feature of the Priora steering wheel, removing it requires great care.

Why change or remove it?

And the removal of the Priora steering wheel must be carried out for repair and maintenance of electrical components.

What to watch if the steering wheel shakes

If the car is driving over bumps, and the steering wheel “kicks” while driving, there is no need to rush to the service station - self-diagnosis in many cases helps to identify the cause of the knocking. The most common reason for this is a malfunction in the steering mechanism.

Steering rods

When they wear out, they receive small scratches due to contact with sand, misfires occur in the operation of the steering rods - this is immediately felt, because play appears when the steering wheel is turned.

Steering rack

When the grooves of the steering rack are practically erased, they do not engage fully with the gear, and each turn vibrates into the multifunction steering wheel.

Steering column cardan

The steering gear mounting clamps must be well tightened.

How to directly remove the Priora steering wheel

To remove this important part, you need to prepare some tools:

Flat head screwdriver;
Pliers;
wrench head 24;
hexagon number 5
Wrench with extension for head.

Very important! Before you begin disassembling and removing the steering wheel, be sure to align the car’s wheels strictly in a “straight ahead” direction! And note how the steering wheel is located. This is necessary for proper reinstallation after removal.

Removal process

Special attention! Under no circumstances should you make sudden movements or hit the device! Spontaneous operation may occur, resulting in serious injury!

Further work will be simpler. Using pliers, carefully disconnect the wires going to the sound signal and move them to the side.

Now the main nut is 24. It needs to be torn off, but not unscrewed or completely removed, but only unscrewed 2-3 turns. After this, gently tap your palms on the back of the Priora steering wheel to move it upward. That is, tear it along the slots. Then check the position of the wheels and steering wheel again. You can make marks with a marker on the steering wheel and column casing.

And only then completely unscrew the nut and finally remove the Priora steering wheel. When removing, be careful not to damage the wires of electronic devices. Pull them out through the special hole and move them to the side.

Installing devices in place

Carry out this operation strictly in the reverse order. Start by laying the wires and then follow the instructions. And again, be especially careful when handling the airbag!

Important! After fully assembling and connecting the battery, test turn on the ignition from the passenger seat! This will protect you from unexpected deployment of the airbag.

Let me move on to the main question.

After changing the steering wheel and making the error light on the dash come on again, I saw the following when I unscrewed the BP:

Under the steering wheel trim, I found the airbag connector that was missing from the steering wheel, which was twisted into the PB lead:

I drove with this kind of art for 5 years, for some reason I never thought about why in a car with PB I don’t have a PB indicator on the panel, but I just didn’t even come across such information to think about it. And all this time I really hoped, that my pillow is working...

Chronology of events according to the previous owners (as I see it): This unfortunate owner was driving along the road and then boom, the “pregnant man” on the panel caught fire. He was very surprised, cursed the VAZ, mocked him for having purchased this car and went to look at “A WHAT IS THERE?” I saw that everything was connected, tugged at the pillow, did not get a reaction. Ay ah ah.

Here, his friend the armchair warrior, not understanding the intricacies of wiring specifically the airbag control units and the contact groups themselves, says: “HEY, LET’S CUT OFF THE CHIP AND PUT IT HERE TO THE LOAD, SO CAN WE CHECK IT?” Without hesitation, they They cut off the connector of the pillow and connect (as in the photo with the inset) the pillow there and, without understanding the principle of operation, again and oh, they get an error.

Then, either because they wanted to sell the car to the next person, or because of the lack of a spare part in the village of Zalupino, or out of complete drunken ignorance, they extinguish the airbag light by breaking off the diode in the instrument panel, twist the pillow like a plug, and wrap all the wires together with inserts in madeline, as is.

(And this is all on a fully working unfired airbag, control unit and almost complete wiring, before their intervention).

Operating principle of the throttle position sensor

At the AVTOVAZ dealer, a local specialist refused to delve into the problem and, throwing in a diagnostic tool, said that I had an airbag error, that’s all, no more, no less, just an airbag error, thanks to him, he really helped me figure out that the airbag error icon is an error pillows. So, the most common problem of airbag failure is the steering column cable, which comes with assembly number 1118-3709315-02 and 1118-3709305 as a separate housing for the old-style airbag, as suggested by Evgeny1117.

Installing the cable is quite simple, but I will describe:

— We put the steering wheel level with the wheels facing straight forward. — We remove the battery terminal, wait a couple of minutes so that there is no residual charge left in the PB coil. — We take out the airbag by unscrewing the two hexagons at the back with a 5-point wrench — We disconnect the connector, having first pulled out the lock with a minus screwdriver small size and remove the pillow— Remove the steering wheel, having previously noted the position.

But this is where the problems lurk, and they are in the little things: — CHECK THE CABLES WITH A MULTIMETER RIGHT IN THE STORE (check the integrity of the wires on the horn and on the airbag contacts, do not hesitate to do this).

To do this, grab thin wires to close the contacts on one side. My first installed cable turned out to be non-functional right out of the box. Of the 4 checked in the store, two also turned out to be defective (either the horn or the airbag did not ring).

But it didn’t end here, I put in a pillow with a whole cable and nothing - the light was still on. The Internet was silent. I was at a loss, I drove to the store and poked other pillows - the malfunction light was on.

Hmm, a VAZ worker told me that the airbag control unit (it is located to the right of the gas pedal, behind the plastic shield under the beard) communicates and is working, which made me think about wiring problems. I went in and took out this orange 50-pin plug, in which, with one pad, only 6 contacts are involved.

I started calling, and there was a short circuit on 4 contacts. Well, how is that, I thought then, I tormented the wiring, disassembled the AMP connector and saw that it was made so that the contacts were closed. What kind of garbage again. On the Internet with such a question about the short circuit of the standard connector block on the forums I found two more potassium growers, the answer to them was silence.

In order to deal with the airbag, I naturally wanted to diagnose the block myself, for this I took a K-Line adapter from VAG KKL 409 and armed myself with OpenDiag 1.4 Free, which can work with Autoliv blocks. I connect and see “Airbag system is missing.”

We arrived, again Google in which a bunch of people have questions such that the block is there, but its OpenDiag diagnostics does not see all versions. Where these questions were stubbornly asked about this utility with a K-Line connector, many advised changing the version, wire, buying a program, changing car or didn't say anything.

I didn’t find any other free (FREE) programs that work with airbag blocks, so things are a little busy. The solution turned out to be simple and the OpenDiag developers suggested it to me in correspondence with support, and also advised me to read the manuals for the program, which I advise everyone who asks in the future. So the problem was in the adapter connection method.
