Safing Sensor

The safing sensor provides vehicle acceleration information to the pedestrian impact detection system (PIDS) module. The safing sensor uses an independent electronic safing method acting through an independent logic circuit such that no single point failure can lead to an unwanted actuation of the hood. The PIDS module provides a two wire current loop interface to the safing sensor. The PIDS module also provides power and ground to the safing sensor over the same two wire discrete interface.
