Impact Sensors
WARNING: This page is about a different car, the 1996 Ford Ranger and 1996 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
Each impact sensor reacts to impacts according to direction and force. It discriminates between impacts that require air bag inflation and impacts that do not.
When an impact occurs requiring air bag inflation, impact sensor contacts close, completing electrical circuit necessary for system operation. See Fig 1. At least 2 sensors, one safing and one front impact, must be activated simultaneously to inflate air bags. Front impact sensors are located at left and right sides of radiator support. Safing sensor is integral with air bag diagnostic monitor.
