Impact Sensor: Description and Operation
Description
Front
FRONT
Two front impact sensors (1) are used on this vehicle, one each for the left and right sides of the vehicle. These sensors are mounted remotely from the
impact sensor that is internal to the Occupant Restraint Controller (ORC). Each front impact sensor is secured with a screw to the back of the right or left
end of the lower radiator crossmember within the engine compartment. The sensor housing has an integral connector receptacle (4), an integral
anti-rotation pin (3), and an integral mounting hole (2) with a metal sleeve to provide crush protection.
The right and left front impact sensors are identical in construction and calibration. A cavity in the center of the molded black plastic impact sensor
housing contains the electronic circuitry of the sensor which includes an electronic communication chip and an electronic impact sensor. Potting material
fills the cavity to seal and protect the internal electronic circuitry and components. The front impact sensors are each connected to the vehicle electrical
system through a dedicated take out and connector of the headlamp and dash wire harness.
The front impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.
Side
SIDE
Two side impact sensors (1) are used on this vehicle when it is equipped with the optional side curtain airbags, one each for the left and right sides of the
vehicle. These sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller (ORC). Each side sensor is
secured with a nut within the right or left B-pillar just above the front seat belt retractors and behind the lower B-pillar trim within the passenger
compartment. The sensor housing has an integral connector receptacle (2), an integral mounting stud (3), and an integral anti-rotation pin.
The right and left side impact sensors are identical in construction and calibration. A cavity in the center of the molded plastic impact sensor housing
contains the electronic circuitry of the sensor which includes an electronic communication chip and an electronic impact sensor. Potting material fills the
cavity to seal and protect the internal electronic circuitry and components. The side impact sensors are each connected to the vehicle electrical system
through a dedicated take out and connector of the body wire harness.
The side impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.
