Impact Sensor: Description and Operation

IMPACT SENSORS

WARNING: 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 and correctly position a new sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.

For these vehicles, the SRS may use up to three satellite sensors in addition to the RCM. The RCM is mounted to the center tunnel between the front seats under the center console. All vehicles will have a front impact severity sensor and it is located in the front-center of the vehicle, mounted on the radiator support bracket. Vehicles equipped with seat side air bags are equipped with two side impact sensors, located on the rocker panel near the base of the B-pillars. Mounting orientation is critical for correct operation of all impact sensors.
