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 5 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 2 front impact severity sensors located in the front-center of the vehicle, behind the grille. In addition, there are 2 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 3 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 2 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.
