ULTRASONIC SENSOR(for Rear) INSTALLATION

CAUTION / NOTICE / HINT

Tech Tips


  • Use the same procedure for the RH and LH sides.

  • The procedure listed below is for the LH side.

PROCEDURE


  1. INSTALL ULTRASONIC SENSOR CLIP

    Note


    • Installing the ultrasonic sensor clip 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.

    Tech Tips

    Use the same procedure for all ultrasonic sensor clips.


    1. Clean the rear bumper assembly surface.


      1. Remove any remaining double-sided tape from the rear bumper assembly.

      2. Wipe off any tape adhesive residue with cleaner.

    2. B004BRYC06
      B0049S8 Primer

      Apply primer to rear bumper assembly on the installation area of the ultrasonic sensor clip using a brush or felt.

      Note


      • 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.

      • Do not touch surfaces to which primer has been applied until the ultrasonic sensor clip has been attached.

    3. Let the primer dry sufficiently.

      Note

      Do not touch applied surfaces until the primer is dry.

      Recommended drying time
      10 minutes or more (at 23°C)

    4. Confirm that the primer has completely dried by touching the rear bumper assembly. Then remove the tape.

    5. Remove the peeling paper of the new ultrasonic sensor clip trying not to touch the adhesional surface.

      Note

      After removing the peeling paper, do not touch the surface of the tape with your fingers or cotton work gloves.

    6. B004BS8C01
      *a Scribed Line

      Align the ultrasonic sensor clip with the scribed line on the front bumper assembly and install it as shown in the illustration.

      Note

      The application strength of the ultrasonic sensor clip will weaken if reapplied. If reapplication is necessary, be sure to replace it with a new one.

      Tech Tips

      Apply pressure so that it does not lift up from the front bumper assembly.

  2. INSTALL REAR CORNER ULTRASONIC SENSOR RETAINER

    Note


    • Installing the rear corner ultrasonic sensor retainer with some double-sided tape remaining may cause poor adhesion. Perform this procedure until sufficiently removed.

    • Make sure to use a cloth when removing. Using a screwdriver, etc., may cause damage and poor adhesion.


    1. Clean the rear bumper assembly surface.


      1. Remove any remaining double-sided tape from the rear bumper assembly.

      2. Wipe off any tape adhesive residue with cleaner.

    2. B004CLLC04
      *a 20 mm (0.787 in.)

      Cover the sensor installation hole with a 20 mm (0.787 in.) circular piece of tape.

    3. B004A1AC02
      B0049S8 Primer

      Apply primer to the area shown in the illustration using a brush or felt.

      Note


      • 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.

      • Do not touch surfaces to which primer has been applied until the rear corner ultrasonic sensor retainer has been attached.

    4. Let the primer dry sufficiently.

      Note

      Do not touch applied surfaces until the primer is dry.

      Recommended drying time
      10 minutes or more (at 23°C)

    5. Confirm that the primer has completely dried by touching the rear bumper assembly. Then remove the tape.

    6. Remove the peeling paper of the new rear corner ultrasonic sensor retainer trying not to touch the adhesional surface.

      Note

      After removing the peeling paper, do not touch the surface of the tape with your fingers or cotton work gloves.

    7. B0049WJC01
      *a Scribed Line
      *b Protrusion of the mark

      Align the rear corner ultrasonic sensor retainer with the mark on the rear bumper assembly and install it as shown in the illustration.

      Note

      The application strength of the ultrasonic rear corner ultrasonic sensor retainer will weaken if reapplied. If reapplication is necessary, be sure to replace it with a new one.

      Tech Tips


      • Apply pressure so that it does not lift up from the rear bumper assembly.

      • Pushing force: 30 N (3.0 kgf) for 3 seconds

  3. INSTALL REAR CORNER ULTRASONIC SENSOR


    1. B004C57C01
      *a Scribed Line
      *b Protrusion of the mark

      Attach the claws to install the rear corner ultrasonic sensor.

      Note

      When reusing the sensor, make sure that each sensor is returned to its original position.

      Tech Tips

      Align the connector with the protrusion of the mark when connecting it.

  4. INSTALL REAR CENTER ULTRASONIC SENSOR RETAINER

    Tech Tips

    Use the same procedure described for the rear corner ultrasonic sensor retainer.

  5. INSTALL REAR CENTER ULTRASONIC SENSOR

    Tech Tips

    Use the same procedure described for the rear corner ultrasonic sensor.
