Fig. 8.41. Security system components
The Supplemental Restraint System (SRS) is designed to work in conjunction with seat belts to enhance safety in crashes and reduce the risk of injury when front and side airbags deploy by keeping front occupants in their seats during a frontal or side impact.
The supplemental passive safety system (SRS) consists of the following elements: the driver's front airbag (located in the center of the steering wheel), which contains a module with a folded airbag and an inflator (gas generator); front passenger front airbag (located in the instrument panel on the passenger side), which contains a module with a folded airbag and an inflator (gas generator); side airbags (located in the outer sidewalls of the driver's and front passenger's seat backs), each of which contains a module with a folded airbag and an inflator (gas generator); sRS electronic control unit (mounted under the center part of the floor console), which controls the entire system; acceleration sensor (accelerometer), which determines the deceleration of the car (the presence of an impact from the outside); clock spring of the intermediate connection located in the steering column; electrical wiring and system connectors; knee buffer (knee bolster), located under the steering column. The external impact recognition function in the SRS electronic control unit is performed by an electronic acceleration sensor, which constantly measures the acceleration of the vehicle and transmits a corresponding signal through the amplifying and filtering circuits to the microprocessor. The additional passive safety system (SRS) is designed in such a way that the airbags will deploy in the event of an accident with a frontal or near-frontal impact of varying severity (from moderate to severe).
Only qualified personnel are allowed to service the supplemental passive restraint systems (SRS) and related components. Before starting work, service personnel should carefully read this manual. Special care must be taken when servicing the SRS system to avoid injury or death to the service personnel (as a result of unauthorized deployment of the air bag) or the driver (as a result of the SRS system not functioning properly after unqualified service or repair).
