The ACC module communicates with other vehicle modules via both public and private bus networks to provide the following features sets (when equipped):

• Adaptive Cruise Control with Stop and Go (ACC+)
• Full Speed Range Forward Collision Mitigation (FSRFCW+)
• Advanced Brake Assist (ABA)

The ACC module:

• Is mounted to the front bumper beam at the centerline of the vehicle. The stamped steel ACC module mounting bracket is secured by two screws to weld nuts installed in the support bracket attached to the face of the bumper support member.
• Has one fixed ball stud and two adjustable ball studs (vertical adjustable and horizontal adjustable) secure the module housing through a pressed fit into molded plastic ball socket clips installed in the mounting bracket.
• Pivots on the fixed ball stud while the upper adjustable ball stud allows module to be vertically aligned and the lower ball stud allows the module to be horizontally aligned after installation.
• Has a molded plastic module cover with a center clearance hole for the module lens/radar dome snaps over the module. This cover conceals a small square mirror and the adjustment screws. The mirror is only used for calibration purposes during the vehicle assembly process.
• Includes an applied connector receptacle that is sealed and secured to the module housing with screws and faces downward when installed on the mounting bracket. The ACC module is connected to the vehicle electrical system through a single dedicated takeout and connector.

The adjustable ball studs and the ACC module cannot be repaired. If ineffective or damaged the entire module unit must be replaced. The ACC bracket assembly must be replaced if service is needed. This is to ensure proper functionality and the press fit nature of the clips.
