What should I pay attention to when disarming the airbag?

It's not that much, just turn off the key.

The first airbag your car will not be violent if it is not driving.

Precautions regarding airbags.

It's not that much, just turn off the key.

To remove the airbag, you need to open the fixed rear of the steering wheel, and then pull it outward with your hand to remove the airbagThe specific steps are as follows:

1. Open the rear cover of the steering wheel.

2. Find the internal fixing screws.

3. Use a tool to remove the fixing screws.

4. Pull the airbag outward to remove it.

5. Disconnect the wire plug to complete the disassembly operation.

In the fuse box, there is an airbag fuse with SRS or Air Bag written on it, and the airbag computer board is generally in front of or below the gear lever.

There is an air belt in the car

The place of the bag is the airbag.

Use a computer airbag system to detect the fault, and then repair it according to the meaning of the fault.

If there is no fault, the computer can directly clear the fault.

Car airbags cannot be manually opened in the normal way. And there are safety hazards.

Automotive airbag systems can be divided into 3 components:

gas generators;

control systems; Gasbag.

The inflator is used to produce a sufficient volume of gas at a fast enough rate to feed the air bag. The control system is used to determine the severity of the collision, decide whether the airbag should be opened, and start the inflator when the conditions are met. The airbag is used to accept the gas from the inflator, control the pressure of the gas and the position and shape of the space occupied by the airbag, and accept the collision of the occupants, absorb the kinetic energy of the collision, thereby achieve the purpose of reducing and reducing the occupants.

After a collision, the airbag is triggered by a collision sensor and an airbag control computer.

1. Modern cars usually have three collision sensors, one under the left and right fenders, and the other is called ** collision sensor, which is located on the control computer. Some cars are also equipped with deceleration sensors to monitor the severity of the crash and allow the computer to determine whether the airbag needs to be triggered.

2. In the event of a collision, the direction of the collision must be within 30 degrees of the longitudinal axis of the car, otherwise the front airbag will not be triggered.

3. After the collision, the collision sensor is triggered, and the signal is transmitted to the computer, and the computer determines that the airbag needs to be triggered to protect the safety of the front occupants, so the airbag detonator circuit is turned on, and the detonator is decomposed, and a large amount of nitrogen is rushed into the airbag, so that the airbag is inflated, and the head of the occupant is blocked due to inertia after the collision, so as to protect the occupants from the injury of cervical spine breakage.

AirbagsThe disassembly needs to be putSteering wheelThe rear part of the fixation is opened, and then the airbag can be removed by pulling it outward with your handThe specific steps are as follows:

1. Open the rear cover of the steering wheel.

2. Find the internal fixing screws.

3. Use a tool to remove the fixing screws.

4. Pull the airbag outward to remove it simply.

5. Disconnect the wire plug to complete the disassembly operation.

Main airbag: The person lies on the seat and turns on the key. There is a screw hole in the steering wheel when turned to the left, and the same method is used on the right.

The computer board of the airbag is usually located in front of or under the gear lever.

Where there is an air bag in the car is an airbag.

Use a computer airbag system to detect the fault, and then repair it according to the meaning of the fault.

If there is no fault, the computer can directly clear the fault.

If you can't solve it, you can go to No. 11, District 13, Wuzhong Auto Parts City, Minhang, Shanghai to help you solve the problem.

Wait for at least 30 seconds after power-off, and pay attention to static electricity.

Hello, disassemble the car airbag.

Precautions are:

1. Do not use detection lamps and voltmeters.

Simple tools such as ohmic meters should be used with a high-impedance multimeter.

Detects the circuitry of the airbag system and the SRS warning light.

2. The disassembly work must be turned off under the ignition switch, and the negative cable of the battery.

It can only be started after 20s of dismantling.

3. Do not put the airbag in an unattended place, and when storing, the buffering side should be placed facing up and the surface facing up. If the airbag is stored with the surface facing down, an accident can occur leading to a serious accident. Never place any object on the airbag assembly.

If the inflatable component lands from a height of 90mm or more, it can no longer be used.

4. In order to prevent damage to the airbag assembly, keep it away from any oil, grease, detergent and water.

5. If the vehicle has a minor collision, although the airbag system is not triggered, the steering wheel pad, front passenger airbag assembly, seat belt retractor and airbag sensor should also be checked.

6. The airbag system can only work once, and the airbag must be replaced after being detonated in an accident. For safety reasons, all components of the air system also need to be replaced, I hope it can help you.

Airbag replacement tips and steps:

The installation of the SRS-40 assembly can be carried out in the following steps:

When unpacking a new component, first check for foreign objects to fall in to ensure that there are no objects inside the assembly;

align the pin in the assembly with the joint base plate and the hole on the steering wheel, then firmly press the component on the generator-sensor assembly, and ensure that the fixing bracket holes on the component are aligned with the holes on both sides of the steering wheel, if these fixing brackets are not installed in place, the cover can not be completely covered on the assembly, affect the appearance effect, pay attention to when installing, do not hit and knock any part of the component and the steering wheel;

Install the bolts, maintain the pressure on the assembly, make the shell buckle intact, and install 4 bolts alternately from one side to the other, and the tightening torque is 7-11N·m;

Finally, install the covers on both sides.

Note: The following procedures should be strictly followed when disassembling airbags:

1. Wear fireproof gloves and protective goggles;

2. Disassemble the covers on both sides of the steering wheel;

3. Unscrew the 4 fixing bolts on both sides;

4 Carefully remove the airbag assembly;

5 Use a small screwdriver to turn the black plastic cleats outward, and carefully rotate the generator counterclockwise until the generator - the sensor seat is aligned with the steering wheel matching slot. Gently take the generator-sensor out of the steering wheel interface;

6. Turn the front wheel to the position in front of you, if you still need to continue to use the steering column and steering wheel, you should mark the relative position of the steering wheel and the steering direction, and then remove the fixing nut of the steering wheel, remove the nut and flat washer, and remove the steering wheel. Before installing the airbag, attention should be paid to: wear fireproof gloves and protective glasses; Smoking is prohibited during operation.

Disassembling the airbags:

1) Turn on the ignition switch first and check whether the airbag indicator on the dashboard is working properly.

2) Turn off the ignition and pull out the key. Disconnect the positive pole of the battery and wait for more than 2min. If the airbag indicator is working abnormally, you should wait for 10min after disconnecting the positive pole of the battery before operating.

3) When disassembling the steering wheel, a special tool should be used to lock the steering column in the "straight forward" position to ensure that the control device and the spiral cable will not be damaged during installation.

4) Only parts with the same part number as the original car can be installed. Igniters have an expiration date, and the expiration date indicated on the parts must be observed.

5) After the battery is turned on, when the ignition switch is turned on, the maintenance personnel should not put the body in the trajectory of the airbag opening.

6) After installation, check whether the airbag indicator is operating normally.

oneWhat are airbags for? Two:What should I pay attention to when replacing an airbag in my car?

Three: How do you care for and maintain your airbags?

In everyday life, don't think that if the airbag is hidden all the time, it doesn't need protection. I believe that everyone will clean the car in daily life, so when cleaning, you must not let the water touch the part of the airbag, because it is easy to cause the airbag to get damp and cannot be opened normally in the event of an accident. And don't let the child play with the main driver and co-pilot often, and don't slap the steering wheel vigorously, which may cause the airbag to open instantly and cause accidents.

Therefore, for the car with airbags installed, it is necessary to be 10 points careful and careful to avoid accidents.

Care should be taken not to damage the airbags, and when replacing the airbags, you should also pay attention to the protection of auto parts, do not hurt other wires, and must not damage the airbags, otherwise the cost of replacing the airbags is very expensive.

We must pay attention to safety, and at the same time we must be better when making it, because only in this way can we achieve the best situation and solve the related problems, and try to go to the 4S shop or repair shop to install the airbag when installing it, so as not to have the airbag to pop out.

As long as the airbag is replaced, the airbag is a disposable product Each airbag can only be used once, and after detonation, it must be returned to the factory for a new airbag. Depending on the model, the airbag is different. Reinstalling a new set of airbags, including an induction system and a computer controller, roughly costs about 5,000-10,000 yuan.

Pay attention to the daily maintenance of airbags. The vehicle's instrument panel is equipped with an airbag indicator light, and under normal circumstances, when the ignition is turned to the ACC position or the ON position, the warning light will be on for about four or five seconds for self-test and then turn off. If the warning light is always on, it indicates that the airbag system is faulty and should be repaired immediately to avoid the airbag malfunction or accidental deployment.

Proper use of airbags:

1. The airbag must be used with the seat belt If the seat belt is not fastened, even if there is an airbag, it can cause serious injury or even death in the event of a collision.

2. Keep a suitable distance from the airbag when riding.

3. Do not place items in front, above or near the airbag Be careful not to place items in front, above or near the airbag, because these items may prevent the airbag from inflating or being ejected in an emergency, causing greater danger.

4. To ensure that the airbag really plays a safe role, the driver and passengers must develop good driving habits and ensure that the chest is kept at a certain distance from the steering wheel.

5. Avoid high temperature The parts of the airbag device should be properly kept, and it should not be placed in a high temperature environment above 85 degrees for a long time.

Car airbags need to be replaced? Novice drivers don't know, it's dangerous to not change by this time.

After the airbag bursts, the main and auxiliary airbags must be replaced, as well as the airbag computer, if the car configuration has satellite sensors installed, it also needs to be replaced, these must be replaced. The seat belt is pre-tensioned, and it is necessary to check whether the initiator is working, and if the initiator is working, it must be replaced. Replacing the airbag computer needs to do some matching, and it is best to go to the 4S store to replace it.

Everyone knows that airbags will**, so you must be careful when disassembling and installing airbags. Here are the precautions for disassembling and assembling the airbags.

Precautions for airbag disassembly and assembly.

01Do not use simple tools such as detection lights, voltmeters, ohmmeters, etc., but use high-impedance multimeters to detect the circuits of airbag systems and SRS warning lights.

02 Disassembly must begin 20 seconds after the ignition switch is turned off and the negative cable of the battery is removed.

Do not leave the airbag unattended. When stored, the seat cushion should be facing upwards with the surface facing upwards. If the airbag is stored face down, it can be accidental, resulting in a serious accident.

Never place anything on the airbag assembly. If the inflatable component falls from more than 90mm to the ground, it cannot be used again.

04To prevent damage to the airbag assembly, keep away from any oil, grease, detergent and water.

05 If the vehicle is involved in a minor collision, although the airbag system is not triggered, the steering wheel pad, front passenger airbag assembly, seat belt tensioner and airbag sensor should also be checked.

06 The airbag modification system can only work once, and the airbag must be replaced after detonation in a clan accident. For safety reasons, all parts of the air pump system need to be replaced.

Special Tips. 01When using a blowtorch or welding equipment, do not approach the inflator to avoid the automatic expansion of the airbag.

02 When repairing, do not expose the steering wheel pads, collision sensors, seat belt tensioners, or front passenger airbag assemblies to hot air or near a fire source. Inflatable components cannot withstand temperatures above 65 percent.

03When removing or replacing the airbag, do not face the front of the airbag assembly.

1. Do not knock or hit the airbag at any time. You should not use water to flush the airbag directly, because the damp airbag will not protect your life at a critical moment.

2. The driver should not lean forward when driving, the sitting posture should be close to the seat, and the back seat should be adjusted to be able to control the car comfortably, leaving enough space for the airbag to fully play a protective role in the event of an accident. Vehicles with cracked airbags in the passenger seat must not be allowed to sit in the front seat or place a child seat in this position, otherwise the airbag will cause great harm to children when it detonates.

3. In the case of not wearing a seat belt, the airbag not only can not protect the occupants, but also has serious lethality to the occupants, and the explosive power of the airbag is amazing, enough to give the driver a heavy blow.

4, the vehicle in the normal excitation only closed cycle, the airbag will not fail, but every 12,000 kilometers after driving, you should go to the 4S shop to check the airbag and its ancillary parts, after 10 years of use, its quality is more difficult to guarantee, must be thoroughly tested, if conditions should be replaced in time.

5. The airbag is a disposable product, which is ejected after the vehicle collides, and then needs to be replaced with a new airbag.
