Parking Sensor

The replacement process for the rear object sensor starts by taking off the rear bumper fascia. Remove the electrical connector from the rear object sensor before using your hands to lift the tabs securing the sensor housing. Installation should not begin with sensors that received previous paint because too much coating will prevent the sensor from operating. Follow these steps to paint the rear object sensor while using a suitable paint thickness gauge for non-ferrous metals to measure that the paint layer stays under 6 mils. The silicone decoupling ring must be properly installed on the sensor to avoid any potential failure conditions. Add the sensor to its housing before connecting the electrical connector then reattach the rear bumper fascia.

The first step to replace a rear object sensor involves removing the rear bumper fascia followed by disconnecting the electrical connector from the rear object sensor. The removal of the rear object sensor starts by lifting the locking tabs located on its housing. Painting the rear object sensor requires using suitable non-ferrous metal equipment to measure paint levels and avoiding refinish work on previously painted sensors because excessive paint will disable the sensor operation. Place the sensor inside the housing before attaching its electrical connector to the rear object sensor and then put the rear bumper fascia back in place.

You need to start by taking off the rear bumper fascia before beginning the replacement process of the rear object sensor. The initial step consists of removing the electrical connector attached to the rear object sensor. The rear object sensor housing requires lifting its locking tabs to separate it from the unit. A new sensor needs to be inserted into the housing while you connect the electrical connector to the rear object sensor before putting back the rear bumper fascia.

The process begins with fascia removal from the rear bumper pair and disconnection of the electrical connector of the rear object sensor. You need to perform two steps for rear object sensor replacement. First lift the locking tabs on the housing then remove the rear object sensor and afterward squeeze the spring to break the attachment to the housing before releasing the housing tabs for extraction. Push the rear object sensor bezel through the fascia in order to remove it. During installation paint the new rear object sensor while avoiding the refinement of existing sensors and verify that the applied paint layer stays within the 6 mils threshold through proper non-ferrous metal paint thickness measurement tools. Clamp the keyhole with the key and push the rear object sensor bezel to rest directly on the fascia. You should mount the housing to its cutouts on the bezel from behind the fascia before putting the spring onto the housing where the spring keys should face up and down. Begin by attaching the decoupling ring to the sensor and put the sensor inside the housing with the connector at the passenger side of the fascia until the sensor tabs reach the cutouts of the housing. Attaching the electrical connector to the rear object sensor completes the installation process by allowing you to reinstall the rear bumper fascia.

The replacement of the rear object sensor begins with fascia removal from the rear bumper after following instructions specific to All Utility or Cadillac ESV models along with Avalanche and Cadillac EXT models. The first step requires users to disconnect the electrical connector from the rear object sensor before lifting locking tabs on the housing to separate the sensor. A paint layer should be applied to the rear object sensor using tools designed for non-ferrous metals before installation but the paint should never exceed 6 mils of thickness. The silicone decoupling ring must be present on the sensor to avoid failure. The rear bumper repair requires the sensor insertion into the housing with subsequent connector reconnection followed by proper installation of rear bumper fascia according to manufacturer guidelines.

Begin by detaching the rear bumper fascia before starting the replacement of the rear object sensor. Before removal you should detach the electrical connector which serves the rear object sensor and then unlock the housing tabs to extract the sensor device. The new sensor installation process should avoid applying finish to existing painted sensors because additional paint will make the sensor incapable of operation. Prior to painting the sensor ensure the paint layer remains below 6 mils by using a suitable non-ferrous paint thickness gauge. To install the sensor, input it into the housing first before plugging in the electrical connector to the rear object sensor and finally reattaching the rear bumper fascia.

The process to replace the rear object sensor requires the removal of the rear bumper fascia followed by electric connector disconnection from the rear object sensor. Push up the holding tabs located on the housing in order to unmount the sensor. Notice that installation of the new sensor requires avoiding paint refinishing of prior sensors because heavy paint layers will make the device nonfunctional. You should paint the rear object sensor while keeping the paint layer under 6 mils with the proper paint thickness gauge intended for non-ferrous metals. Place the sensor inside the housing before you reconnect the electrical connector to the rear object sensor and afterward reattach the rear bumper fascia.

Begin with bumper fascia removal when handling a rear object sensor replacement task. The next step requires you to disconnect the electrical connector which serves the rear object sensor. Pull up the locking tabs located on the housing unit to extract the sensor. Installation of the new sensor requires avoiding paint application to existing sensors since this excess material will damage the sensor operation. Apply paint on the rear object sensor making sure it maintains a paint thickness of not more than 6 mils through the use of the suitable paint thickness gauge for non-ferrous metals. Install the sensor within the housing before you will connect the electrical connector and reinstall the rear bumper fascia.

Insert the new sensor into the housing and connect the electrical connector to the rear object sensor.

Insert the sensor into the housing.

Paint the new front object sensor, ensuring not to refinish previously painted sensors, and check that the paint thickness does not exceed 6 mils using a suitable paint thickness gauge for non-ferrous metals.
