  Q: How to replace the rear Parking Assist Distance Sensor on Cadillac DeVille?

  A:

  The replacement process for the rear object sensor requires you to begin by taking off the rear bumper fascia before disconnecting the electrical connector of the rear object sensor. Raise the retaining clips on the housing before taking out the rear object sensor. A finger pressure on the spring releases the sensor inside the housing so the user can remove it by releasing the tab locks. Use the bezel to pass through the fascia and it will drop out. Previously painted sensors require replacement because adding new paint layer would disable their functionality. Use a non-ferrous metal paint thickness gauge to check the fresh paint applied to the rear object sensor until it reaches 6 mils thickness. Drive the keyhole of the sensor bezel into its position on the fascia after pressing the bezel ring for a smooth surface with the fascia. Apply spring keys to the housing while inserting it through the rear fascia. Position the housing with complete attachment between spring keys on both the top and bottom edges. Before continuing the installation process fit the spring first to the housing and then attach the decoupling ring to the sensor. Insert the sensor into the housing through the connector side while directing it toward the right side of the fascia. Then fasten the sensor's tabs into the housing cutouts. The electrical connector should be attached to the rear object sensor while reinstalling the rear bumper fascia.
