Impact Sensor: Description and Operation

SENSORS

WARNING:
- The restraints control module (RCM) orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been involved in a collision in which the center tunnel area has been damaged, inspect the mounting and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags have deployed. In addition, make sure the area of the RCM mounting is restored to its original condition.
- 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. Replace and correctly position the sensor or any other damaged SRS components whether or not the air bag is deployed.

For this vehicle, the SRS uses a RCM and 5 external impact sensors. The RCM is mounted to the center tunnel beneath the console. All vehicles have a front impact severity sensor that is located in the front-center of the vehicle, mounted under the lower radiator support. All vehicles also have 4 additional side impact sensors. The 4 additional sensors are located at the base of each B-pillar and C-pillar. The LH and RH C-pillar mounted side impact sensors are not interchangeable. Mounting orientation is critical for correct operation of all impact and rollover sensors.
