SRS AIR BAG SYSTEM SYSTEM DIAGRAM PASSENGER-SIDE S-SENSOR AIR BAG MODULE I IG1 B+ HORN RELAY CLOCK SPRING BACK-UP BATTERY I AIR BAG SYSTEM WARNING LIGHT SENSOR -7 System Operation During collision When either of the D-sensors and the S-sensor are activated (closed) simultaneously by shock of a colli- sion, the circuit to the inflator is completed. The inflator creates nitrogen gas and the air bag is deployed. The air bag vents the nitrogen gas from the vent hole on the back side of the bag to reduce shock to the driver and to allow easier exit from the vehicle. During normal condition and malfunction The diagnostic module constantly monitors the components and wiring of the air bag system for malfunc- tion, open circuits, and short circuits. .J If a malfunction is detected, the diagnostic module illuminates or flashes the warning light. In the case of a short circuit in the sensors or sensor harnesses, the diagnostic module activates the warning light and shuts down the system to prevent accidental deployment of the air bag.
