A crash sensor system is provided for a vehicle. The system includes an electronic control unit (ECU) disposed on the vehicle generally along a longitudinal axis of the vehicle. The ECU has a first accelerometer to measure longitudinal acceleration of the vehicle and a second accelerometer to measure lateral acceleration of the vehicle during a crash event; and a processor circuit. Front crash satellite sensors are electrically connected to the ECU and are mounted at the front of the vehicle to detect a front or a rear crash event. Each of the front crash satellite sensors has a polarity defining a sensing direction. When a front or rear crash event occurs, the first accelerometer is constructed and arranged to determine if the crash occurred at the front or at the rear of the vehicle, regardless of the polarity of the front crash satellite sensors.
