Module, Adaptive Cruise Control (ACCM): Description
The Adaptive Cruise Control (ACC) module (1) 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 rivet nuts installed in the face of the bumper support member. This module is also the primary component of the Forward Collision Warning (FCW) feature of the Electronic Vehicle Information Center (EVIC).
One fixed ball stud (4) and two adjustable ball studs (3) secure the module housing through a pressed fit into molded plastic ball socket clips installed in the mounting bracket. The module pivots on the fixed ball stud while the two adjustable ball studs allow the module to be vertically aligned after installation.
The ACC module electronic circuitry is sealed and protected within a die cast aluminum housing. A molded plastic cover and a lens or radar dome (5) faces forward through an opening in the center of the front fascia lower airflow grille texture that is trimmed with a bezel snapped into the texture opening. A molded plastic module bezel or mirror cover with a center clearance hole for the module lens snaps over the module and conceals a small square mirror in one corner of the module cover that is used for calibration purposes during the module manufacturing process.
The ACC module includes an applied connector receptacle (2) 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 of the FEM wire harness.
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.
