Discrimination Sensor
WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
The discrimination sensor provides discrete force information to the pedestrian impact detection system (PIDS) module. The PIDS module uses measurable pedestrian impact data sent from the discrimination sensor to determine the severity of the impact. The PIDS module provides a two wire current loop interface to the discrimination sensor. The PIDS module also provides power and ground to the discrimination sensor over two separate discrete circuits.
