Impact Sensor: Description and Operation
Impact Sensor - Description
DESCRIPTION
Vehicles equipped with side impact airbags use two impact or Satellite Acceleration Sensors (SAS). One is located on each respective side body B-pillar.
There are two SAS (standard) in the front of the vehicle to aid in frontal, angular and offset impact detection.
The satellite acceleration sensors are electronic accelerometers that sense the rate of vehicle deceleration and when combined with the Occupant
Restraint Controller (ORC) accelerometer provides verification of the direction and severity of a side impact. Each sensor also contains an electronic
communication chip that allows the unit to communicate the sensor status as well as sensor fault information to the microprocessor in the ORC.
Refer to the appropriate wiring information and Body Diagnostic Procedures for diagnosis and testing.
