A service professional should disconnect the electrical connector from the parking aid sensor before starting any repair work on the sensor. Press the retaining tabs before taking out the sensor from the rear
Bumper. Put the new parking aid sensor inside the rear bumper opening and allow the retaining tabs to grab it. Finish by connecting the electrical connector. You should check the parking aid sensor PIDs using diagnostic tools post-installation to verify that PIDs display no objects while the parking aid sensor attenuation PIDs show values between 0-16 ms.
