Impact Sensors

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

Three impact sensors are used. Two impact sensors are mounted on headlight carrier surface on left and right sides of vehicle. Two impact sensors are located on radiator support behind grille opening reinforcement. ACM contains the third impact sensor, which is called the safing sensor. Impact sensors are inertia switches which complete an electrical circuit when a front-end collision creates sufficient "G" force. For air bag to deploy, safing sensor and at least one impact sensor must activate at same time.
