Cruise Control Module (CCM)
WARNING: This page is about a different car, the 2023 Ford Mustang Mach-E. However, it is still accessible from the selected car via links, so may be relevant.
The CCM contains a radar sensing unit which measures the relative speed and the distance between the front of the vehicle and the vehicle being followed. The CCM is responsible for requesting the PCM to increase or decrease vehicle speed and the ABS module to brake, when necessary.
