34 Safety Crash sensing Crash sensing and diagnostic modules have been used in automobiles since airbags were first produced. The technical information gained from these modules can be useful to understanding the circumstances that led to the airbag deployment. In addition, information from many field events can be used in the aggregate to help manufacturers and others better understand real world crashes. This, in turn, can lead to improved automotive safety. Your vehicle is equipped with two electronic frontal sensors, which helps the sensing system distinguish between a moderate frontal impact and a more severe frontal impact. Your vehicle is also equipped with a crash sensing and diagnostic module, which records information about the frontal airbag system. The module records information about the readiness of the system, when the system commands airbag inflation and driver's safety belt usage at deployment or in a near-deployment crash. The module also records speed, engine rpm, brake and throttle data etc. Airbag warning lamp WARNING • If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly.
