Control Module

The control module is secured with two screws to the underside of the LH (left-hand) front fender reinforcement, behind the wheel arch liner. The control module is hardwired to the other system components and is also connected to the high speed CAN (controller area network) bus. The control module receives ambient air temperature, ignition state and vehicle speed on the high speed CAN bus.

The control module uses signals from the PCS and the accelerometers to determine if the impact on the bumper is a pedestrian or some 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.
