What is airbag?What are airbags used for?

An airbag is a vehicle safety device designed to rapidly inflate in the event of a collision, providing a cushioning barrier between the occupants and the interior surface of the vehicle. Airbags, typically made of thin nylon fabric, inflate through a chemical reaction triggered by sensors that detect a collision.
Airbags are mainly used for the following purposes:
① Occupant protection:
Airbags help protect vehicle occupants from impact forces during a collision, particularly in frontal and near-frontal collisions. They reduce the risk of head, chest and upper body injuries by absorbing and dispersing impact energy.
② Supplementary Restraint System (SRS):
Airbags are part of a vehicle's supplemental restraint system, which also includes seat belts and other safety features. These systems work together to minimize the risk of injury to the occupants in the event of a collision.
③ Collision mitigation:
While airbags cannot prevent a collision, they can reduce the severity of an injury by providing a cushioning cushion between the occupant and hard surfaces in the vehicle, such as the steering wheel, dashboard, or door panels.
④ Collision severity perception:
Modern vehicles are equipped with sensors to detect the severity and type of collision. These sensors trigger airbag deployment only when necessary, ensuring the airbags inflate with the appropriate force and timing to provide maximum protection while minimizing the risk of unnecessary deployment.
⑤ Multi-point protection:
In addition to front airbags, many vehicles are equipped with side, curtain, and knee airbags to provide protection in various types of crash and impact scenarios. These multi-point airbag systems provide comprehensive protection for the occupants.

Overall, airbags are a key safety feature in modern vehicles that significantly reduce the risk of serious injury or death in the event of a collision. However, they are most effective when used in conjunction with other safety systems, such as seat belts, and appropriate vehicle design designed to minimize crash forces.

What is airbag reset? Why do you need airbag reset?

An airbag reset is the process of resetting or clearing the airbag control module (also known as the airbag computer, SRS module or ACM) after an airbag deployment event or malfunction. The airbag control module is a component of the vehicle's Supplemental Restraint System (SRS) and monitors the status of airbags, seatbelt pretensioners and other safety components.
Here are the reasons why you may need to perform an airbag reset:
① After the airbag is deployed:
When an air bag deploys in response to a collision, the air bag control module records event data, including crash severity and sensor information. After the vehicle has been serviced, resetting or clearing the airbag control module is often necessary to eliminate the fault code indicating deployment and allow the system to operate normally again.
② Clear fault code:
If the airbag warning light on the dashboard comes on, it indicates a fault or malfunction in the airbag system. Performing an airbag reset clears the fault codes stored in the airbag control module and resets the system, allowing it to recheck for any ongoing issues.
③ During maintenance or repair:
During routine maintenance or repairs that involve the removal or replacement of airbag-related components, such as the steering wheel, seat belts, or airbag modules, it may be necessary to reset the airbag control module to ensure proper SRS operation.
④ To ensure safety and compliance:
Resetting the airbag control module is critical to ensuring the safety of vehicle occupants. The malfunctioning airbag system can compromise occupant protection in the event of a collision, so it's vital that any issues are addressed promptly and the system is functioning properly.
⑤ Pass vehicle inspection or certification:
In some jurisdictions, vehicles must undergo a safety inspection or certification, which includes an airbag system inspection. In order to pass these checks, it may be necessary to reset the airbag control module and make sure the airbag warning light is off.
