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 and bracket for deformation. Install and correctly position a new sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
Vehicle With Side Air Bags
For these vehicles, the SRS employs five impact sensors. One of the sensors is integral to the RCM and is not separately serviceable. The RCM is mounted on the center tunnel under the instrument panel. There are two front impact severity sensors located in the front-center of the vehicle, behind the grille. In addition, there are two side impact sensors. The side impact sensors are located at the base of each B-pillar below the safety belt retractor and pretensioner. Mounting orientation is critical for correct operation of all impact sensors.
Vehicles Without Side Air Bags
For these vehicles, the SRS employs three impact sensors. One of the sensors is integral to the RCM and is not separately serviceable. The RCM is mounted on the center tunnel under the instrument panel. There are two front impact severity sensors located in the front-center of the vehicle, behind the grille. Mounting orientation is critical for correct operation of all impact sensors.
