In the US, Ford Motor Company issued position statements covering Ford and Lincoln brand vehicles providing guidance to collision repair facilities on the extent of repairs of bumper fascias allowed on vehicles equipped with advanced driver assistance systems (ADAS).
According to the statements, “During body repairs that involve front and rear bumper fascias, it is critical that the vehicle be restored to proper operating condition to ensure that these important safety systems function correctly. The statements specify that the measurement of the topcoat finish requires the use of an ultrasonic paint thickness gauge, such as PosiTector 200 or Phase II UTG-2900, available through Ford’s Rotunda equipment program.
They also include the following points that provide an overview of bumper fascia repairs:
- Paint repairs can be made if the material thickness does not exceed 12 mils (300 microns) in total thickness.
- Use of any filler materials or reinforcement tapes to repair substrate damage is not permitted.
- Use of hot staples or plastic welding to repair cracks or damage is not permitted.
- Repair of any sonic-welded sensor retainer rings or tabs is not allowed, due to possible misalignment and incorrect operation of the sensor.
- Note that vehicle wraps, bumper stickers and aftermarket accessories in the area of the fascia can create system operation concerns.
The position statements also warn that since reconditioned, refurbished or salvage bumper fascias may have been repaired using substrate repairs, including the use of filler material, plastic welding and hot staples, which can interfere with ADAS operation, it does not approve the use of reconditioned, refurbished or salvage bumper fascias.
