THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53 • Driver and Front Passenger Seat Belt Pretensioners • Front Passenger Seat Occupant Classification System (OCS) − Occupant Classification Module − Passenger Airbag Disabled (PAD) Indicator Light − Interconnecting Wiring − Pressure Sensor, Bladder Assembly, and Belt Tension Sensor How The Airbag System Works • The Occupant Restraint Controller (ORC) determines if a frontal collision is severe enough to require the airbags to inflate. Based on the level of collision severity, the front control module determines the proper rate of inflation. The front airbag inflators are designed to provide different rates of airbag inflation from direction provided by the ORC. The ORC may modify the rate of inflation based on the occupant size provided by the Occupant Classification Module. The ORC will not detect roll over, or rear impacts. The ORC monitors the readiness of the electronic parts of the system whenever the ignition switch is in the START or RUN positions. These include all of the items listed above except the steering wheel and column, and knee bolsters. If the key is in the OFF position, in the ACC position, or not in the ignition, the airbags are not on and will not inflate.
