Rear Parking Aid Sensors Bonding Bracket In Bumper Cover

Rear Parking Aid Sensors Bonding Bracket In Bumper Cover

To assist in aligning the sensor retainers in their proper positions when bonding, sensor location punched holes with corresponding retainer bonding adhesive surfaces are marked on the inside of the bumper cover. Before proceeding with bonding procedure, ensure sensor retainer and bumper cover materials are between 15 °C (59 °F) and 25 °C (77 °F).

Procedure

- Clean the marked adhesive surfaces - 1 - on the inside of the bumper thoroughly with isopropyl alcohol.






- Apply the bonding agent "Scotchmount 4298" evenly in the marked adhesion surface - 1 -.

- Let the adhesive air dry for approximately 5 minutes.

- Allocate the sensor brackets to be bonded to their proper installation location. Refer to => [ Allocation of the parking
aid sensor on the inside of the rear bumper cover: ] Parking Aid Sensors, Rear.

- Remove both protection foils from sensor retainer bonding area - 2 - so that a gray surface becomes visible.

- Align the sensor bracket - 2 - with respect to marked adhesive surface - 1 - so that there is a uniform edge of approximately 3 mm.

• Make sure that recesses for sensor connection in the sensor bracket face in the correct direction as depicted in the assignment. If sensor bracket is glued in incorrectly, connection wires for sensor are too short.

- Press the sensor bracket - 2 - with significant pressure into the bumper cover for approximately 10 seconds.

• The contact pressure and pressing time are crucial for the adhesive durability!
