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 sensor is secured with a screw to the backs of the right and left
vertical members of the radiator support 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 impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.
Side
SIDE
Six side impact sensors (1) are used on this vehicle to support the standard side curtain airbags, three each for the left and right sides of the vehicle.
