SIDE - C-PILLAR





Two acceleration-type C-pillar side impact sensors (1) are used on this vehicle when it is equipped with the 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 screw to the lower C-pillar just above the rear door opening sill within the passenger compartment. The sensor housing has an integral connector receptacle (3), an integral locating anti-rotation pin, and an integral mounting hole (2).

The right and left C-pillar side impact sensors are identical in construction and calibration. However, the connector orientation in the vehicle is reversed. The connector receptacle faces forward on the right side of the vehicle, and faces rearward on the left side of 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. The cavity is filled with a potting material to seal and protect the internal electronic circuitry and components. The C-pillar side impact sensors are each connected to the vehicle electrical system through a dedicated take out and connector of the body wire harness.

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