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, a new RCM must be installed whether or not the air bags have deployed. In addition, make sure the area of the RCM mounting is restored to its original condition. Failure to follow these instructions may increase the risk of personal injury or death in a crash.
- 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 a new and correctly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed. Failure to follow these instructions may increase the risk of personal injury or death in a crash.

For these vehicles, the SRS uses 5 satellite sensors in addition to the RCM. The RCM is mounted to the center tunnel beneath the console. All vehicles will have one front impact severity sensor located in the front-center area of the vehicle, behind the grille mounted on the lower radiator support. The first row impact sensors are located in each of the front doors behind the trim panel, the second row sensors are located on each C-pillar. The side impact sensors are not interchangeable between the first and second row. Mounting orientation is critical for correct operation of all impact sensors.
