  1. The Adaptive Cruise Control (ACC) module is located on a bracket secured near the center of the underside of the front bumper support member of the Front End Module (FEM) behind the front fascia.
  2. Remove the ACC cover from the front fascia.
  3. Remove the smaller plastic bezel (mirror cover) from over the front of the ACC module housing.
  4. Using standard glass cleaner and a clean soft towel, remove any dirt or road salt from the convex molded dark plastic lens dome on the face of the ACC module as well as from the suction cup of the vertical alignment tool.
  5. Carefully slide the vertical alignment tool over the sensor housing until the suction cup rests against the lens of the ACC module.
    NOTE:

    It may take several attempts to get the suction cup of the special tool to fasten securely to the ACC module. If necessary, lightly wet the suction cup with clean water to help improve adhesion.

  6. Depress the plunger of the vertical alignment tool to engage the suction cup and attach the special tool securely to the lens of the ACC module.

Use the 3.5 millimeter hex nut driver (Special Tool No. (special tool #10243-2, Driver, Nut)) to rotate the vertical adjustment ball stud (2) that secures the sensor (1) to the mounting bracket as necessary to center the bubble of the spirit level between the two center marks on the vial of the level located on the top of the vertical alignment tool.
  8. Depress the center release button of the special tool to release the suction cup from the sensor lens and remove the special tool from the ACC module.

  10. Perform the "ACC aim mode auto alignment" procedure using a diagnostic scan tool. Follow the directions on the screen.
  11. Reinstall the smaller plastic bezel (mirror cover) onto the front of the sensor housing. Care must be taken to orient the bezel properly to ensure proper retention.
  12. Install the ACC cover to the fascia.
