Impact Sensors

Each impact sensor assembly electrical switch reacts to impacts according to direction and force. It discriminates between impacts that require air bag inflation and impacts that do not require air bag inflation.

When an impact occurs requiring air bag inflation, impact sensor contacts close, completing electrical circuit necessary for system operation. See Fig 1 . Minimum of 2 sensors, one rear safing and one front impact, must be activated simultaneously to inflate air bags. There are 3 impact sensors mounted in the vehicle. Two front impact sensors and one rear safing impact sensor.

Front impact sensors are located at the front of right and left radiator support. The rear safing impact sensor is located behind driver's lower left kick panel. See Figure .
