IV. BACKGROUND





In the curtain shield airbag (CSA) system of the subject vehicle, there are two sensors in the airbag sensor assembly which are designed to detect vehicle roll angle. If one of these sensors malfunctions, the airbag warning light (Malfunction indicator Light: MIL) will illuminate and the roll detection system will be suspended; however, the airbag (CSA) remains available in the event of a side crash. If both sensors fail nearly simultaneously after initial airbag system check, the CSA and the seat belt pretensioner could be inadvertently activated. Inadvertent activation of the CSA and/or the seat belt pretensioner can cause injury to a vehicle occupant.
