The airbag indicator is the sign that the airbag is in working condition, i.e., "a person seated in the car with a seat belt on it, and a small ball in front of it".

While. When this light is on, it represents the working state of the airbag; Generally, when the key door is opened and the electric door is turned on, the airbag indicator will go off after about 3-4 seconds, which indicates the system.

It worked and worked; If it does not light up or stays on, it means that the airbag system is faulty and needs to be serviced in time.

Although the failure of the airbag system does not affect the driving of the vehicle, it is necessary to send it for repair and troubleshooting in time, so as to continue to provide effective anti-collision protection for the occupants of the vehicle; While.

When the airbag system fails, the car should be sent to a 4S shop or repair shop in time to check and repair the airbag.

About the reason why the airbag light is always on:

1. False alarm: Other reasons cause the airbag light to be on, such as battery power loss.

2. The airbag is not in good contact, and the line plug or wire is loose.

3. The seat belt assembly is faulty or the plug is loose.

4. The airbag itself fails or expires.

Under normal circumstances, the icon does not appear, and if it appears, the airbag will stop working.

1. The airbag sensor usually has 3 4 collision sensors that are installed on the front side and the middle of the car;

2. Such as the inside of the front two fenders of the car, under the headlamp brackets on both sides, on the left and right sides of the radiator frame, under the left and right dashboards, etc.;

3. After the external collision sensor is detonated, it can be reused. However, some models have sensors that are disposable.

A full airbag is a passive safety system device that airbags when a car crashes.

The pressure sensor of the system.

and accelerometers in the ECU.

If the conditions of the airbag are met, the airbag will be inflated and popped out at the same time to protect the driver's head and chest, so as to ensure personal safety.

What are the conditions that need to be met for the airbag to pop out?

Collision angle trigger sensor: The airbag does not pop out for no reason, it is equipped with a sensor, and if the car does not touch the airbag's sensor when it collides, the airbag will not pop out. Generally, if there is a serious frontal collision, it will only pop normally, but if the collision angle of the vehicle is wrong, such as the headlights, front wheels, or the back of the car, the airbag may not be deployed.

Speed and collision object: In addition to the collision angle, the deployment of the airbag is also related to the driving speed and the collision object. When the vehicle is traveling at a speed of more than 50 km/h and the collision object is rigid, the airbag will be ready to deploy.

If the speed is less than 50 km/h, the airbag may not activate when it stops crashing into a vehicle of the same class. Suppose it's a pile of sand and mollusks.

And so on the general safety argument that the airbag will not pop open.

Where did the airbag pop out?

Normally, car manufacturers install airbags in the main driver and co-driver. We don't seem to have a trace of the steering wheel.

And on the outer dial in front of the co-pilot, is where the airbag is deployed. The thinnest of these places is about the thinnest point, and when the gas starts to expand, it pushes through the weakest points and then quickly pops out.

If 23 airbags pop open at the same time, will it happen? The foreigner drove the car directly! Ling Jinheng.

Under normal circumstances, the icon does not appear, and if it appears, the airbag will stop working.

There are generally 3 4 crash sensors for airbag sensors, which are installed in the front and middle of the body, such as the inside of the front two fenders of the car, under the headlamp brackets on both sides, on the left and right sides of the radiator frame, and under the left and right dashboards. Once the external collision sensor is detonated, it can be reused. But some models have sensors that are disposable, such as demeanor.

Precautions for the use of airbags.

Avoid accidental bumps and vibrations. Components such as airbag sensors are sensitive to collisions and shocks, so they should be avoided as much as possible to avoid unnecessary suddenness of the airbags.

Children should be especially careful when using airbags. At present, many airbags are designed for adults, including the position and height of the airbag in the car. When the airbag is inflated, it can cause injury to the child in the front seat. It is advisable to place the child in the middle of the back row and secure it.

The airbag indicator is marked with a ball in front and a person sitting in the back.

The airbag system mainly includes two parts, one is the seat belt pretensioner mechanism, the other is the airbag, which is mainly composed of a collision sensor, an airbag indicator, an airbag computer and an airbag, the working principle is not detailed, and the plugs that play a connecting role between these important components are also equally important, and some plugs are also specially set up with a double locking mechanism to ensure a more reliable connection, and in order to distinguish them from other plugs.

Precautions for airbag use

Do not change the airbag system and its surrounding layout without authorization, and do not change the airbag system wiring without authorization. Also, do not change the front bumper and the front structure of the vehicle without permission, as this will affect the airbag system's judgment of collision. If the vehicle has side airbags mounted on the seats, then do not attach seat covers to the seats.

Don't expect the airbag to get out of the seat cover in a moment. Do not tap the part where the airbag is installed, such as the steering wheel. The serious consequences of using the steering wheel can be an accident or damage to the airbag's detonator.

The Anhail Sakura full airbag failure is caused by the side airbag plug moving the seat under the seat.

Airbag function: It is to reduce the degree of injury of passengers. The electronic airbag control system is a passive safety protection system (see Vehicle Safety Performance).

When used in conjunction with seat belts, it can provide effective anti-collision protection for passengers. In the event of a car collision, the rate of head injuries can be reduced by 25%, and the rate of face-to-face return injuries can be reduced by 80%.

Airbag composition: Airbags are mainly composed of airbag sensors, anti-collision airbags and electronic control devices. The driver-side crash avoidance airbag device is located on the steering wheel, while the passenger-side crash avoidance airbag device is generally mounted on the instrument panel.

The empty airbag sensor is installed on the left, right, and middle of the cab partition, and the middle empty airbag sensor and the airbag system are installed together with the electronic control unit. The airbag assembly is mainly composed of an airbag, an inflator and an igniter. Electronic control devices, such as data acquisition and data processing, diagnose the reliability of the airbag, ensure that when the predetermined value is reached, the ignition signal will be sent out in time, and the timing ignition can ensure that the driving inflator has sufficient driving current.

Causes of airbag failure:1. The airbag system plug is disconnected or in poor contact; 2.

Loose ground wire somewhere in the car; 3.The car battery is dead; 4.Faulty airbag balance spring and crash sensor.

An airbag system is a passive safety protection system that works in conjunction with seat belts to provide effective collision protection for passengers. Airbags are mainly composed of airbag sensors, anti-collision airbags, and electronic control devices. When a car collides while driving, the airbag sensor first receives the collision signal, and as long as it reaches the specified strength, the sensor will act and send a signal to the electronic controller.

After the electronic controller receives the signal, it compares it with its original stored signal, and when the airbag condition is reached, the driving circuit sends a starting signal to the inflator in the airbag module; After the inflator receives the signal, ignite the inflator to produce a large amount of gas, which enters the airbag after filtration and cooling, and the airbag breaks through the cushion body in a very short time and expands rapidly, forming an elastic air cushion in front of the driver or occupant, leaking, shrinking and absorbing impact energy in time, so as to effectively protect the head and chest of the human body from injury or reduce the degree of injury.

An electronic control of safety airbag airbag system is a passive safety (see Automotive Safety Performance) protection system that works in conjunction with seat belts to provide effective crash protection for occupants. In the event of a car collision, car airbags can reduce the rate of head injuries by 25% to the face.

The injury rate is reduced by about 8 0%.

The reason why the airbag light is on.

1. The circuit problem of the reason why the airbag light is on.

When we talk about circuits, we all know the problem of no active circuits, there are all kinds of situations, see if it may be connected abnormally. It is commonly used to use a detector to check the fault, whether the line is smooth, such as the signal line voltage is normal, and measure whether there are signs of breaking the iron wire. See if you can enter its control unit, test and check one by one, such as hair.

Now it is impossible to enter, and then unplug the computer of the relevant components, whether it is caused by interference with its signal data cable.

Check whether the control computer of the airbag can work normally, enter the airbag, the computer inquires about the fault and finds that it is a permanent fault, and the steering wheel is replaced and eliminated.

Except. If you still find that you can't enter, there is still this kind of visible perception of the sign, at this time, you can check whether its power supply line can be energized.

This is the reason why the detector cannot detect it due to poor tie-up. Check the two plugs of the splitter on the relay box, which is the airbag signal line.

Turn the streets. Unplug one of the plugs to detect it in the control unit if found to be normal.

2. The reason for the airbag light is the plug problem.

In fact, many times, it is just that the connected plug appears loose. This may be due to people accidentally touching it, but people often don't notice it. While.

When the plug is loose, you just need to find the plug under the seat in the back row and press it tightly.

3. The sensor and data failure of the airbag light is the reason for it.

If there is a sensor failure and data reading error, it should be strictly in accordance with the maintenance manual test and precautions of various car models and styles, and carry out professional maintenance and maintenance.

At this time, it should be carried out under the operation of professionals.

Airbags are also related to some small actions of our car with the owner, and some owners like to modify the interior decoration of the car, which will affect the normal connection of the sensor.

, which in turn affects the normal deployment of the airbag.
