The air-bag SRS computer is known as an air-bag SRS control unit, which can be understood as a miniature computer system, when a collision occurs the collision sensor data to obtain the collision information, and then according to the computer calculates the need to pop out the airbag, if necessary, it will trigger the air-bag SRS gas generator, generating instantaneous high-pressure gas to pop out the airbag.

After the air-bag SRS computer triggers the collision, it will store the collision fault code, in the early days due to technical limitations, it can not clear the fault code, resulting in the air-bag SRS computer being almost disposable, as long as the collision must be replaced, the maintenance cost is very high. With the development of the times, the auto repair industry reduced the cost of repair, so the birth of the airbag SRS repair technology.

Airbag computer repair refers to the air-bag SRS computer failure due to collision and other reasons by using specialized equipment, the air-bag SRS collision fault code removal, restores to the state before the collision, so that it can continue to load the car use.
