Supplemental Restraint System System Operation The supplemental restraint system (srs) is designed to work in concert with the seat belts to further prevent personal injury during a head-on collision with another object. The srs utilizes an air bag module front impact sensors, a clock spring low pressure switch and a diagnostic module With the battery cables connected, the srs system is energized and monitoring the forward impact sensors and the safing sensor for collision confirmation messages. When the vehicle strikes or is struck by, another object (such as a tree, wall, another vehicle, etc), the forward impact sensors and safing sensor send impulses to the diagnostic module which determines the force and direction of the impact. Based on this information the diagnostic module either deploys or does not deploy the air bag. Inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour( 16 to 24 km per hour). the airbag s inflation system reacts sodium azide(nan3) with potassium nitrate(Kno3)to produce nitrogen gas(Fig. 12-1).
