Impact Sensor: Description and Operation
Impact Sensor - Description
Vehicle Front
VEHICLE 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 outboard side of the cooling module, just inboard 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.
Side - Front Door
SIDE - FRONT DOOR
Two pressure-type front door side impact sensors (2) are used on this vehicle when it is equipped with the side curtain airbags or the optional seat (also
known as thorax) 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 two screws and is sealed by a resilient gasket (1) to the front door module
carrier on the inside of the front door. The sensors are concealed behind the front door trim panel within the passenger compartment.
