Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Sensor Alignment
- The Adaptive Cruise Control (ACC) module sensor 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.
- Unsnap and remove the molded plastic ACC fascia closeout bezel in the center of the grille texture insert of the lower air intake opening of the front fascia to gain access to the ACC adjustment screws.
- Remove the smaller plastic mirror cover bezel from over the front of the sensor housing.
- Using standard glass cleaner and a clean soft towel, remove any dirt or road salt from the convex molded dark plastic lens (radar dome) on the face of the sensor as well as from the suction cup of the vertical alignment tool.
- Carefully slide the vertical alignment tool (special tool #2024500080, Kit, Adaptive Cruise Control Sensor Alignment) over the sensor housing until the suction cup rests against the lens of the sensor.NOTE:
It may take several attempts to get the suction cup of the special tool to fasten securely to the sensor. If necessary, lightly wet the suction cup with clean water to help improve adhesion.
- Depress the plunger of the vertical alignment tool to engage the suction cup and attach the special tool securely to the lens of the sensor.
- Use the appropriate size torx driver to rotate the vertical adjustment ball stud that secures the sensor 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.
- 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 sensor.
- Perform the "ACC aim mode auto alignment". This is the ACC sensors horizontal alignment procedure. Perform this routine using a diagnostic scan tool and follow the directions on the screen.
- 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.
- Reinstall the molded plastic ACC fascia closeout bezel into the center of the grille texture insert of the lower air intake opening of the front fascia.
