2. INSTALL REAR CORNER ULTRASONIC SENSOR RETAINER

NOTICE:

  • Installing the rear corner ultrasonic sensor retainer with some double-sided tape remaining may cause poor adhesion. Perform this procedure until sufficiently removed it.
  • Make sure to use a cloth when removing. Using a screwdriver, etc., may cause damage and poor adhesion.

HINT:

Use the same procedure for both rear corner ultrasonic sensor retainers.

(a) Clean the rear bumper cover surface.

(1) Remove the double-sided tape from the rear bumper cover.

(2) Wipe off any tape adhesive residue with cleaner.

(b) Cover the sensor installation hole form the outside of the bumper cover with a 17 mm (0.67 in.) square piece of tape.

(c) Using a brush or felt, apply primer or equivalent to the rear corner ultrasonic sensor retainer installation area.

NOTICE:

  • Replace the brush or felt if it is dirty or has become hardened.
  • Keep any painted surface free from primer.
  • If the primer contacts a painted surface, it may leave light primer marks. Therefore, use protective tape when using liquid primer.
