Impact Sensors

WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. 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 left and right side of radiator closure panel. See Fig 1 and Fig 2 . The third sensor, called the safing sensor, is located inside ASDM. See Figure . 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 the same time.
