Description And Operation: Description
WARNING: This page is about a different car, the 2019 Fiat 500X. However, it is still accessible from the selected car via links, so may be relevant.
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.
