One of the main passive security systems of the modern car is airbags, which are called AirBag (in the literal translation of the "air bag") or in the astounding "AERBEG". Their main purpose is to mitigate the blow when a vehicle collide with another car or a fixed obstacle. For the trouble-free operation of this elastic shell, which in the event of danger is filled with gas, there is a specially designed airbag control unit.

General principle of work

The airbag system consists of three main components:

• the module itself pillow;
• airbag sensors;
• diagnostic Block Aerbega.

When the airbag sensor fixes the blow, it transmits an alarm, the system works, and the pillow is completely disclosed for thirty-thirty five milliseconds. Most modern systems equipped with devices that accumulate sufficient electricity for the introduction of pillows into action, even if the main accumulator battery will be damaged by impact. Any melt airbag monitors the diagnostic unit, which is activated at the moment of inclusion of the car. If the scanner detects a malfunction, the Airbag light lights up on the instrument panel.

Why is the airbag light bulb?

Many users face that the airbag light bulb lights up without any visible causes and does not go out, starting to glow again each time the ignition is turned on. What does this phenomenon testify?

Normally, this should occur only after the pillows are triggered, that is, after the occurrence emergency situationSince the memory of the electronic unit contains information about the collision. In this case, the Aerbeg is on until the airbag replacement. If there was no accident, then one of three reasons takes place:

• fault of the pillow itself;
• problems with contacts (contacts sent or oxidized);
• a different kind of airbag errors.

Errors and failures can be a lot. For example, when the car takes turns to use two people of different growth and the set, for example, husband and wife, they constantly move it, reinstalling according to their parameters. This leads to the fact that contacts are departed, and the system detects this violation.

Characteristic failures can be called a driver airbag error and the sensor error of the front passenger. They often occur when a touch of a cabin, tuning and minor repairs, for example, when removing the steering wheel or a fence of seats. The reason that the airbag is constantly burning in the car (its light bulb on the instrument panel) can be a malfunction of sensors, that is, the airbag sensors.

How to eliminate airbag error?

Almost every autofora can be found actively discussed topic: "The airbag caught fire! What to do?". Many tips are given, how to get rid of this misfortune, which are based mainly to throwing the terminals or disconnecting airbags. Do anything with air plugs yourself in no way. Firstly, before them, the unfair person is not so easy to get. Secondly, as the driver can eliminate the breakdown, if he does not know exactly, why is Airbag burns? Continue to drive with a burning alarm - the more dangerous. At a critical moment, the pillow, most likely, will not work, but she can hit the driver in the face at the most unexpected moment.

If airbag caught fire, then you need to contact a specialized car service, equipped with a scanner, with which you can erase errors in the system's electronic memory, identify problems and malfunctions and eliminate them. Our specialists will determine why the airbag caught fire in your car, will perform required repair, that is, restoring external view and functional properties of the pillow, replacing the components of the sensors or the pillows themselves. Your life depends on the security systems, so they should always be in good condition, and their repair can only be trusted to professionals.

You go, it happens, and some light bulb lights up on the tidy. "Who asked her?", "Think." And already calculate the cost of repair in the head. But immediately fall into the despondency and you should not panic. A lightbulb can simply indicate a minor error. Cars are not easy mechanisms, but they are not so difficult to understand. Especially since they are talking to their owners, reporting faults. An unexpected knock appeared in Hodovka. Then, of course, in the service and the lift. Or, for example, the icon on the dashboard lights up. Some motorists are interested in why the airbag lights caught fire? This is usually happening without visible reasons. About this on the Internet, confused drivers speak countless forums, trying to find out what a catch. That only on the pages of the communities will not meet. Someone burns the pillow icon, others have "red fastened man" or the inscription Airbag, others immediately give win-win tips, they say, so they had or their acquaintances. But here is not so simple.

Safety above all

Statistics of the traffic police are becoming more and more stable, accidents are registered daily, and therefore motorists are more often thinking about security. After all, as they say, not you, so in you. Especially in adverse road conditions, for example, in ice. Refer to road services here is not worth it. Not cleaned, not sprinkled. And so! Safety belts, undoubtedly, the thing is necessary, but without pillows in modern cars anywhere. What is interesting, they appeared first in airplanes. It happened in the forties of the last century. Cars began to equip passive security in the seventies. Now in the configuration of all modern cars is airbag. Such inscriptions can be found on the glove compartment, racks, curtains, steering, rear seats. The security system includes pillows, belts, pretensioners, sickness, shock sensors and control unit. The pillows themselves are a shell, filled, for example, by air. It is revealed only when the sensor, fixing the blow, passes the alarm.

Without panic!

The security box indicator always lights up when the engine is started. This happens only for a few seconds. Together with him, the battery icons, as well as the "Check", telling us about the errors in the operation of the engine systems also light up. Together with the already listed blinks and the handbrake icon. The airbag system is tested during the ignition switching on. But after a few seconds, all the bulbs go out. If one of them continues to burn, it can tell the owner of a certain fault. The SRS / Airbag signal can tell about the failure of the entire security system, and not just the work of the pillows. If the system gives a failure, the lamp will burn, because the self-dialect of the self-diagnosis records the fault code and includes a control light. Most often, the driver's airbag errors occur and the front passenger sensor sensor.

There may be several reasons

So what is the reason? The entire security system is interconnected by wiring. If you recently removed the trim to sneak off the car with noise insulation, we reinforced yourself the windows, it means that you can easily be the reason for the tanning signal lamp. This can happen and not only during repairs. For example, the car is constantly exploited by two people: large man And his fragile spouse. Family couple All the time you have to move the driver's seat. From this can be pulled out wires. If the car was bought from hand, and you are not familiar with his story, the cause of the tanned light can be a violation of the integrity of the pillows. So, perhaps, the promised "not broken-not painted" is not at all. Light bulb airbags and when an input signaling is incorrect. In general, the reasons may be a lot:

1. Water getting into contacts or seat belt lock - Be careful in the shower and during the car wash;
2. Incorrect replacement of any details under which the wires pass. Among them - the steering wheel, dashboard, armchairs and doors;
3. Malfunction of the control module;
4. Damage to the shock sensors;
5. Expired shelf life of pillows. It is 8-10 years;
6. Insufficient;
7. Bad connection of wiring connections;
8. Terminals and fuses;
9. Malfunction of the pillow itself.

Pillow malfunction light can also light up after the "unsuccessful" tuning or. So fans of transformations should be careful. It is best to get acquainted with the wiring scheme in advance so that some wire does not seem excess. After removing or replacing various parts - chairs, doors, steering wheel, front panel and even bumpers, you can contact a hundred. There may have a service for resetting the airbag control unit. It will not hit the pocket. It will cost about 500-1000 rubles. This will help get rid of the errors when moving the wires and contacts.

If the pillow light flashes from time to time, it is most likely talking about wiring wear. In some place bad contact. For example, a steady wire. It is best to find in advance until he gives himself a felt differently. After all, the faulty wiring can cause short circuit. And it's not so easy to cope with fire in the car. He can burn her down for counting seconds.

The error came out!

Lit and not go out? As mentioned above, there are a lot of reasons. Throw off the error, of course, you can independently. This is done elementary. To the proven, albeit is not a Dedovsky method, many resorted repeatedly. You can throw off the terminals for a few minutes. After starting the engine, the light bulb will not light up again. The second method is a bit more complicated - disabling airbags. But still they must fulfill their basic functions. Therefore, the reason must be installed, and the fault is eliminated. The faster the better. Here can help in the service of the official dealer. No tips for "experienced" or mechanics will not help in a situation. Only computer diagnostics can recognize the cause. After connecting the wires, you will tell you what the error reports the light bulb taverned on the dashboard. In case your car is still on warranty, you should contact the salon where the car was purchased.

Be carefull!

The security system should always be properly, because no one knows when an accident may occur. Even if you are confident in your driving skills, it can happen when the accident is not waiting at all. Therefore, to postpone the elimination of errors that the light bulb of airbags reports, the long box is not worth it. Be careful !

»Airbag error - AIRBAG light burns

Cause Bugle Airbags

• failing off the passenger airbag shutdown button,
• because there is no airbag,
• because of the fracture of the wire under the seat,
• because broken mat presence of the passenger
• produced car repair with affecting airbag items and did not erase the error
• sRS Podrut Ring Wear
• faulty seat belt pretensioners

One thing is clear - this error should not be ignored.

Safety bag - One of the greatest achievements of designers in the field of passenger safety. Thus, if a red light bulb on the dashboard lights up, reporting about the error, do not slow down with the cause of the cause. Otherwise, the pillows may not work, or vice versa - others will shift, in which there is no need for a triggering. In any case, you will suffer.

Each car equipped with airbags after turning the key in the ignition lock (no need to even run the engine) produces system diagnostics. If everything is in order, the red indicator goes out. But when the computer detects an error, even while driving, the indicator lights up. Before switching to the list of the most common faults, one part should be paid.

So, the error message does not necessarily mean that the pillows in this car are still installed and did not work. When it comes to a car that did not participate in an accident or collision, the lack of an indicator signal is the norm. Worse, if a used car was purchased, in which the indicator was deceived through the emulator (resistor, which allows the switch to recognize the pillow and not show errors). Even the diagnostic computer may not notice this. Sometimes fraud is detected in removing from the LED instrument panel or lighting light light lighting light bulb. Good news is that the emulator is set less frequently than before.

Prices for used pillows fell (For example, dismantled with cars brought from the UK). It is definitely better to install a used airbag than not to have it at all. How to check if the emulator is installed in this machine? This is not a simple task with which even a knowledgeable electrician sometimes does not cope.

Only effective method - Remove the lid and make sure that the pillow is installed under it, but it is not always possible to do.

When the indicator of the faulty airbag lights up

As already mentioned, the luminous error indicator indicates several reasons, but more often the error occurs due to the interruption of the chain.

For example, disabling the connector under any of the seats. In some cars (Fiat Stilo), due to a sharp shift of the passenger seat. The indicator lights up and when cleaning the cabin, when the cables are nearing inattention, the brush of the vacuum cleaner. Sometimes it is enough to connect the connector again and the bulb will go out. But some cars will require connectivity diagnostic Computer.

Credited due to the age of wire connecting airbags with the control switch, including the Airbag harness at the wheel. Some electricians are repaired wiring, others recommend replacing the harnesses with new ones.

The Passenger Presence mat is damaged. Thanks to him, in a situation where no one sits next to the driver, in the event of a frontal collision, none of the airbags should not be shot to protect the passenger. Matt breakdowns occur or because of the aging, or by the fault of users themselves - the sensors do not like when they are based on the knee. And so they do in a situation where you get things lying on the back sofa, or while cleaning the car's salon to get to the hidden corners. Mats do not repair. You should find a used working or buy new. It is not recommended to connect the emulator that will pay off the pillow indicator, but will make it so that they will work even when the chair will be empty.

No shock sensors are good. They are installed on spars or chassis. The task of the sensors is to enable the corresponding pillows when colliding. The sensors fail due to corrosion, damage to the wiring harness, although they are resistant to negative effects.

The airbag indicator may burn as a result of an inept repair of electricians.

Computer Diagnostics Airbags and Airbag Block

The exact cause of the light bulb is determined using a diagnostic computer. It should be remembered that reset error messages does not solve the problem and helps only when the error is temporary (short-term shutdown of the connector). In a situation where the error is only deleted, rather than the causes of the fault, the indicator will surely light up again.

Repair of faults related to airbags is better to entrust professionals. In addition, an amateur electrician can close the wires so, and the pillow will shoot him in his face.

Remember that in each machine, the airbag indicator has different look. It may not be, but an inscription AIRBAG or SRS appears. Sometimes the indicator signal should be understood as a notification of the passenger's airbag shutdown. For example, a pillow is disconnected when a chair for the transport of a child is installed on the front seat. The cushion light bulb signals a malfunction or destruction after an accident belt tensioners.

Previously, the service life of the pillow was equal to 10-15 years, today the service life is increased.

A modern car consists of a variety of complex systems. The SRS Airbag passive security system is hardly the most important in the car, because the health and life of people depends on the quality of its work in an emergency. If it fails, the corresponding light lights up on the dashboard. This light bulb usually causes panic from drivers, because it suggests that airbags in case of an accident may not work. Today we will get acquainted with the SRS system, find out what to do if the airbag lights caught fire, and consider several specific examples From the life of car owners.

SRS system

In all modern machines in the cabin you can meet the marking means? Dana abbreviation is decrypted as Supplementary Restrain System, which in Russian means a "deployed security system". Often, the AIR BAG phrase is added to it, which is translated as a "airbag". It is the pillows that are the main attribute of the system. But besides them, SRS includes also:

1. Seat belts.
2. Tension fixtures.
3. Shock sensors.
4. Pyropathriped.
5. Electronic control system.

Like any other car node, the security system can fail when breaking one small details or loss of reliable interconnection between the elements.

Principle of operation

When the sensor fixes the blow, it transmits alarm to the system, and the pillows are disclosed. From the moment of impact before the opening of the pillows passes 30-35 milliseconds. In modern cars there are special batteries that introduce the system into action even when the main battery is damaged.

Why does the Airbag indicator light up?

If the airbag lights caught fire on your car, it means that some problem arose in the system. The indicator can burn constantly or blinking with a certain periodicity, telling the driver thereby the error code.

If everything is fine in the security system, then when the ignition is turned on, the light flashes about six times. Thus, the system gives the driver to understand that everything is in order with it. After that, the indicator itself sweats and reminds of itself only when the motor starts start. But if some problems or errors are detected, the lamp continues to burn. Once the electronics noticed the error, it automatically starts the search for the cause and transmits the malfunction code into memory.

After a certain period of time after the first testing, the system checks all the elements again. If the failure identification was erroneous or features indicating a malfunction, disappeared, the diagnostic module erases an error code sent to memory earlier. In this case, the lamp goes out, and the car continues to work as usual. When the system re-recognizes a malfunction, the light bulb continues to flash.

Common faults

As you already understood if the airbag lights tanned in your car, it means that the system is necessarily present. Modern manufacturers Cars are suitable for the security system with special responsibility. Therefore, the devices involved in this node are considered the most reliable and trouble-free in the entire car. So if the airbag malfunction lights caught fire, it makes no sense to complain about the unreliability of the system itself. Remember that SRS Airbag's diagnostic organs are very rarely mistaken!

If the AirBag indicator is burning in your car, it may be a consequence of such problems:

1. Violation of the integrity of one of the elements of the system. It does not matter, it's small or big, important or not very.
2. Violation of the signal between the elements of the system.
3. Problems with contacts located in the doorway. Most often this happens after repair or replacing contacts. If you forget to connect one of the connectors, the light bulb will begin to burn.
4. Damage to impact sensors.
5. Circuit or all kinds of damage to the wiring in the circuit of the system.
6. Simple problemwhich many people remember in the last place, breaking the half of the car.
7. Software or mechanical damage to the SRS Airbag system control unit.
8. Violation of the integrity and consistency of the elements of the chain, due to the replacement or repair of alarm.
9. Neackurability when replacing chairs or cleaning in the cabin. Under the seats lies with the wiring, damaged by the entire chain of instruments.
10. Restoring pillows after an accident, without resetting memory in the control unit.
11. Heavy resistance on one of the pillows.
12. Too low voltage in the car power grid. If the airbag lights caught fire for this reason, when replacing the battery, everything will fall into place.
13. Exceeding the period of operation of the pyropatrons or the pillows themselves. As a rule, this period is about 10 years.
14. Unprofessional tuning, which often leads to a violation of the integrity of the electrical circuit or sensors.
15. Wetting sensors during car wash.
16. Incorrect battery replacement.
17. Neacking steering replacement.

Elimination of the problem

Now we know why the airbag lights light up. It remains only to find out how to solve this problem. Troubleshooting consists of such steps:

1. To begin with, the system itself checks its performance during the inclusion of ignition. If errors are revealed, it writes their code to the central control unit.
2. The wizard reads the code and determines the cause of the problem.
3. Special diagnostic equipment checks the system.
4. The master performs repair operations.
5. It remains only to update the memory of the control unit, and the problem is solved.

Trying at home to repair SRS Airbag problems is urged ultimately not recommended! First, it is not so easy to get to the system elements. Secondly, to eliminate the breakdown, it needs to be revealed. And without special equipment it's impossible. Thirdly, this system You can save your life, so it's better to trust it with the repair of professionals. Ride, ignoring the indicator, is also dangerous. If the accident happens, the pillows may not be disclosed. But they can easily hit you with neither from this.

Now consider several examples of solving this issue by drivers different marks machines.

The airbag on the "Chevrolet-Lacetti" lights up

Once the driver of this car noticed that during the engine launch, the SRS light flashes, but it burns for five seconds, then goes out. So repeated every time at the engine's institution. The reason was the following - removing the chair, the driver disconnected the pillow and turned on the ignition to access the cigarette lighter. The system considered an error, from this and the airbag light on the "Lacetti" caught fire. Then, when the chair and contacts were returned to the place, the car continued to remind the problem.

"Renault Logan"

The owner of this car has a more significant problem. It all started with the fact that the SRS indicator came out once. Since the driver had some experience in this matter, he decided to figure it out independently. Having removed the front driver's pillow, the man disconnected the wires from it (pre-disabling the "mass"), removed the steering wheel and the plastic cover. By the way, he had to remove the steering wheel with a comrade, since he was tightly pressed. This happens not only on Renault Logan cars. The airbag lights caught fire, as it turned out, after removing the lid, due to the fact that the cushion cable was cut off, and from two sides. After removing the block of the submissive switches, the man pulled the spoiled element and replaced it.

"Nissan-Nout"

After cleaning in the car, the owner noticed that the SRS indicator burns. Apparently, the reason was that the man hindered a vacuum cleaner, located under the seat. At first he tried to simply remove the battery terminal. On some machines it helps if the airbag lights caught fire. "Nissan" is arranged so that the error information is immediately saved. Fortunately, this is not the only feature of Nissan cars. It turns out that in the cars of this brand to clean the system from errors, you need to make such a sequence of actions:

1. Squeeze the brake pedal. It should not be released until the end of the procedure.
2. Turn the key to "ON" mode.
3. Wait until the SRS indicator starts flashing.
4. Quickly translate the key to the "OFF" position.
5. Points from the second to the fourth need to repeat 3-5 times.

If it does not help, then there is a serious problem, and you need to contact the masters.

Toyota-Camry

One motorist caught fire airbag on Camry-40 on a very interesting reason. As already mentioned, not only pillows are connected to the security system, but also belts. So, once in an emergency at the owner of Toyota-Camry, as they say, "shot the belt". He fired - hence, he was resettled at such a speed that the stopper worked, and the belt was jammed. Pillows were not revealed, but the situation was recognized by the system as an emergency and preserved as a result of which the light was caught fire.

Conclusion

Summarizing the foregoing, it is worth noting that the SRS indicator can light up for various reasons. In any case, you should not wait that he will go out. If the bulb is burning, and you do not have assumptions about the reason for her breakdown, contact the masters to protect yourself and your passengers.

Any modern car is equipped with various security tools.

When such a light bulb, airbag caught fire - clearly indicates that at the moment the pillows do not work. The meaning can not only burn constantly, but also blink, like a check of Endzhina, thereby pointing out the specific error code in the security system.

Thus, the mandatory attribute of the car was the presence of at least one airbag cushion. And when problems with this system itself, the driver, on the dashboard, signals lamp airbags. In any machine, you can find the "SRS" marking somewhere in the front of the cabin, which is a reduction from the "Supplementary Restrain System" or how the system of expanded security system sounds in Russian. It consists of a certain number of pillows, as well as elements such as:

• seat belts;
• sickness;
• tension fixtures;
• shock sensors;
• electronic control system to all this, which is the brain of automotive security.

SRS system, like any other complex car node, can fail due to breakdowns of a certain part or loss of reliability of the relationship between the elements. You have happened exactly, if the airbag lights caught fire on the dashboard, the indicator of which differs in different models cars.
