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 two flanged hex nuts to two studs on 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 (2), an integral anti-rotation pin (3), and two integral mounting holes (4) with metal sleeves to provide crush protection.

The right and left front impact sensors are identical in construction and calibration. A label on the sensor is imprinted with an arrow, which should always be pointed forward in the vehicle. 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 and a stamped cover (5) is crimped over 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.
