Impact Sensor: Description and Operation
IMPACT SENSORSWARNING: Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Install and correctly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
Impact sensors are electronic devices that provide crash severity information to the RCM to assist in deployment determination. All vehicles will have a front impact severity sensor located behind the front radiator grille. The RCM is mounted under the front driver seat. Mounting orientation is critical for correct operation of all impact sensors.
