Rear Object Sensor Housing Replacement
Rear Object Sensor Housing Replacement
Removal Procedure
The housings are adhesively retained to the backside of the fascia and must be removed prior to paint refinish operations every time the fascia is
refinished due to paint bridging concerns. Adhesive tape cannot be removed and re-used with retention confidence. Thus the rear object sensor housing
is considered a onetime use application, requiring that all 4 housings be replaced every time the fascia is refinished.
1. Remove the rear fascia. Refer to Rear Bumper Fascia Replacement (See: Body and Frame/Bumper/Rear Bumper/Rear Bumper Cover /
Fascia/Service and Repair/Rear Bumper Fascia Replacement).
2. Remove the rear object sensor. Refer to Rear Object Sensor Replacement (See: Rear Object Sensor Replacement).
3. Remove the sensor housing (1) from the fascia.
4. Remove all remaining adhesive.
Installation Procedure
Important: The adhesive and mating surfaces temperature must be between 19-43°C (66-110°F).
1. Clean the sensor housing mating surface of the fascia with a lint-free rag using a naptha solvent or equivalent.
2. Mating surface must be dry before applying adhesion promoter.
