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 restraint system operation. If a vehicle equipped with an 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 these vehicles, the SRS uses 2 satellite sensors in addition to the RCM. The RCM is mounted to the center tunnel beneath the instrument panel. All vehicles will have 2 front impact severity sensors located in the front-center area of the vehicle, behind the grille mounted on the radiator support. Mounting orientation and torque is critical for correct operation of all impact sensors and the RCM.
