Control Module
The control module is secured to the underside of the wing behind the wheelarch liner with two screws. The control module is hardwired to the other system components and is also connected to the High Speed (HS) CAN bus. The control module receives ambient air temperature, Ignition state and vehicle reference speed on the HS CAN bus.
The Control Module uses signals from the Pedestrian Contact Sensor (PCS) and the accelerometers to determine if the impact on the bumper is a pedestrian or an other object. The system will always deploy where the control module determines a pedestrian impact. The system minimizes deployment for other impacts that are similar to pedestrian impact, such as traffic cones.
