The ACC sensor contains the software required to operate normal Cruise Control, ACC+, and FCW+. The ACC sensor determines the distance to a target vehicle and the speed at which the target vehicle is approached. If the ACC sensor determines that intervention is required, the ACC sensor sends a message to other modules over CAN-C to activate audible, visual and haptic warnings. The ACC sensor also sends torque requests to the PCM and brake requests to the ABS module.
