Front-End Discriminating Sensor

WARNING: This page is about a different car, the 2000 GMC Safari and 2000 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.

Front-end discriminating sensor is an auxiliary sensor which assists SDM in determining when deployment should occur by providing an input signal. Although front-end discriminating sensor is mechanical, it is not part of deployment loop.
