Sensor, Impact: Description: Front

Two acceleration-type 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 back of the front end module carrier on either side of the cooling module, just below the inboard end of each front lamp unit housing within the engine compartment. The sensor housing has an integral connector receptacle (3), an integral locating and anti-rotation pin, and an integral mounting hole (2).

The right and left front 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. The cavity is filled with a potting material 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 front end module wire harness.

These acceleration-type front impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.
