Incorrect handling, storage, transportation, installation or dismantling of the airbag components can lead to their unintended operation and injury to people or to disruption of the normal functioning of the system as a whole

Single action SNAP components.

Driver airbag module (MNPBV), front passenger airbag module (MNPBP), seat belt pretensioners with spacers, airbag system control unit (BUS-airbag) deployed as a result of an accident or other incident needs to be replaced.

When the MNPBV is triggered on a car, the steering wheel and the connector with the rotating device must also be replaced.

SNPB components (MNPBV, MNPBP, BUSNPB and seat belt pre-tensioners), which have or have not worked, but with signs of damage, must be replaced.

It is allowed to install system components corresponding only to the model of this car. Rejected components of the SNPB should be placed in the reject isolation room in the storage warehouse.

If the steering wheel with MNPBV is damaged, the steering wheel must be replaced.

The presence of the airbag on the car is confirmed by the inscription "AIRBAG" on the cover of the driver's airbag module installed on the steering wheel, the inscription "AIRBAG" on the cover of the front passenger airbag module located in the instrument panel.

The state of the airbag is controlled by a diagnostic signaling device (yellow "SRS" inscription) located in the control lamp unit, which, after turning on the ignition, in the absence of malfunctions, should turn on for 6-7 seconds and turn off.

If you turn off the ignition and turn it on before 15 seconds have elapsed, the signaling device does not turn on.

If after that the lamp lights up and continues to burn constantly, then this indicates a malfunction in the passive safety system.

Replacement of the components of the SNPB is carried out:

- upon detection of malfunctions in the components of the SNPB;

- in case of damage to the components of the SNPB;

- when the SNPB or its individual components are triggered.

It is recommended that the airbag modules and front seat belt pretensioners be replaced after 10 years from the date of manufacture.

The date of manufacture is indicated on the label on the module housing and on the front seat belt pretensioners.

After removing the failed airbag modules or front seat belt pretensioners from the vehicle due to mechanical damage or after the expiration of the recommended operation period, it is necessary to carry out the procedure for forced activation of the gas generators of the airbag components as soon as possible

Available airbag modules and front seat belt pretensioners do not pose a risk to people or the environment.

After disassembly, the components of the SNAP components are subject to disposal in accordance with the type of materials in accordance with the current requirements and standards for ecology and environmental protection.

Safety measures when working with SNPB

Attention! When carrying out repair and maintenance work on vehicles equipped with airbags, the ignition switch must be in the "OFF" state, the "ground" wire terminal must be disconnected from the battery.

Before checking the airbag wiring for a short or open circuit, disconnect the harness blocks from the driver and front passenger airbag modules, seat belt pretensioners, and the airbag control unit.

All work related to the components of the airbag must be performed in clean cotton gloves and goggles.

It is necessary to store the SNPB components in the original packaging corresponding to hazard class 1.4S or 1.4G according to GOST 19433.

The place for storing the components of the airbag should be protected from unauthorized access by persons not allowed to handle them.

- store SNPB components at temperatures above +45° C;

- when carrying out repair work on a car with an airbag in painting and thermal chambers, the ignition switch must be in the "OFF" state, the "ground" wire terminal must be disconnected from the battery, it is forbidden to leave a car with an airbag in the chamber at a temperature above 105 ° C;

- install on the car the components of the airbag with mechanical damage;

- use AC power tools when installing and removing airbag modules and seat belt pretensioners;

- install the airbag components on the car after they fall from a height of more than 1 m onto a hard surface;

- place any stickers or objects on the covers of the airbag modules.

Pretensioners and airbag modules from salvaged vehicles cannot be used on other vehicles. If the pretensioners and airbag modules are outdated or damaged,

The warranty period ends and devices may malfunction.

If the car has more than one pretensioner in an accident, one of them may work while the other remains active.

Do not use lubricants, cleaners or similar substances when working with pretensioners. Failure to do so may result in a fire hazard!

If the vehicle is subjected to thermal or shock (dynamic) load during operation, the pretensioner must be removed before starting work.

Pretensioners should not be soldered, welded, drilled, stitched or machined in any way.

Do not attempt to repair a damaged pretensioner.

Do not block or cover the gas generator outlet. Do not place anything on the pretensioner.

Do not tamper with or change ignition circuit cables or pads.

Possible ways to dispose of damaged pretensioners are suggested, for example, by licensed companies specializing in the handling of pyrotechnic materials.

In the event of interruption or breakdown, the pretensioners must be stored in a safe, enclosed place. It is forbidden to leave pretensioners in the open unattended.

It is necessary to take the necessary measures to ground the pretensioners to prevent the possibility of unintentional ignition due to static electricity.

This is especially important if the pretensioner wiring is damaged or the safety shunt is not active.

When handling airbag components, only one airbag module or one pretensioner is allowed to be handled and carried by one person.

Carry the module by holding it firmly with both hands so that the decorative cover and base of the container are not directed at your body.

If the airbag module is removed from its original packaging before being installed in the vehicle or its assembly, it must be placed on a flat, hard table surface no more than 1 m high with the decorative cover up.

There must be no loose objects in the airbag deployment area.

It is allowed to place no more than one item on the table. The pretensioner must be carried by hand with the pyrotechnic tube, lock down, and turned away from the body.

Precautions safety when carrying SNPB

Attention! Never hold the pretensioner by the cable.

In case of accidental damage to the gas generator of the airbag module and the pretensioner, which led to its disassembly and scattering of the pyrotechnic substance, it is necessary to localize the place, blocking the access of all persons.

Assemble the components using a tool that does not generate static electricity. The person collecting the components must wear rubber gloves and goggles.

Place the collected components in a paper bag together with the gloves in which the collection was made, then place them in a reject isolator in a separate metal container with a lockable lid.

All persons who come into contact with parts of the opened gas generator should wash their hands and face thoroughly with soap and warm water.

When the airbag components are triggered, it is necessary to wait about 30 minutes for the airbag components to cool down.

Depending on the location of the components of the airbag, carry out operations for their selection or dismantling from the vehicle or its assembly and place them in a reject isolation room (storage conditions are normal).

After finishing work with the triggered components of the SNPB, wash your hands with soapy water in warm water.

Medical assistance

In cases where people around were hit by a pyrotechnic substance from a disassembled gas generator or people around were injured when system components were triggered, it is necessary:

- call a doctor on duty or an ambulance for first aid;

- if a pyrotechnic substance gets into the eyes, rinse them with warm water, drip "albucid 20%";

- when swallowing a pyrotechnic substance, rinse the stomach, rinse your mouth with ascorbic acid and drink 3-4 sips;

- in case of contact with the skin of a pyrotechnic substance, wash the skin with ascorbic acid, in case of a burn, after washing, apply Panthenol or Olazol ointment to the affected skin;

- when inhaling a pyrotechnic substance, place the victim in fresh air;

- in case of any symptoms of malaise, immediately consult a doctor.

The purpose and principle of operation of the SNPB

The airbag system is an additional means of protecting the driver and front passenger wearing seat belts, and is designed to reduce the severity of injury in frontal collisions of the vehicle in traffic accidents.

SNPB is triggered depending on the strength of the car's collision with various obstacles.

In the event of a normal operation in an emergency, the airbag starts regardless of the state of fastening the driver or front passenger with seat belts.

Therefore, the use of seat belts by the driver and front passenger is a prerequisite for the effective operation of the airbag.

The airbag system starts functioning after the ignition is turned on and is controlled by an electronic unit (BUSNPB) with a self-diagnosis function.

The system is activated by applying an electrical signal from the BUSNPB to the airbag module(s) and the seat belt pretensioner.

If the airbag is triggered, the upper part of the cover of the facing module of the airbag, when the airbag is filled with gas, breaks in structurally defined places and opens.

Through the opening formed by the gas, the airbag bag opens in front of the steering wheel or instrument panel.

The pillow filling time is about 30-40 ms.

Simultaneously with the deployment of the airbags, the front seat belt pretensioner is activated, ensuring that the slack in the belt is tightened and securely fixed in the driver's and front passenger's seat.

After the airbag inflates, the overpressure releases the gas through special openings located at the back of the airbag bag, thereby preventing the driver or passenger from colliding with the interior of the car and at the same time mitigating the severity of the impact of their head and chest.
