The Radar incorporates the software necessary to operate the FCW+ function. The sensor determines the distance to a target vehicle and the speed at which the target vehicle is approached. If the 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 sensor also sends torque requests to the PCM and brake requests to the ABS module.
