PROCEDURE

1. INSTALL ULTRASONIC SENSOR CUSHION SET

NOTICE: Perform this procedure only when replacement of the ultrasonic sensor cushion set is necessary.

2. INSTALL REAR CORNER ULTRASONIC SENSOR RETAINER

NOTICE: Perform this procedure only when replacement of the rear corner ultrasonic sensor retainer is necessary.

(1) Clean the rear bumper assembly surface:

1. When reusing the rear bumper assembly, remove remaining double-sided tape from the rear bumper assembly.

2. Using a heat light, heat the rear bumper assembly surface.

Heating Temperature:

CAUTION:

• Do not touch the heat light and heated parts.
• Touching the heat light may result in burns.
• Touching heated parts for a long time may result in burns.

NOTICE:

Do not heat the rear bumper assembly excessively.

3. Remove any remaining double-sided tape from the rear bumper assembly and wipe off any tape adhesive residue with cleaner.

4. Clean the installation area surface.

NOTICE:

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

(2) Cover the sensor installation hole from the outside of the rear bumper assembly with a 30 mm (1.18 in.) square piece of tape.

(3) Primer application:

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

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

2. Let the primer dry sufficiently.

NOTICE:

Do not touch applied surfaces until the primer is dry.

Recommended drying time:

10 Minutes or more (at 23°C (73°F))

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

(4) Install a new rear corner ultrasonic sensor retainer:

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

NOTICE:

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

2. Using a heat light, heat the rear bumper assembly and rear corner ultrasonic sensor retainer.

Heating Temperature:

CAUTION:

• Do not touch the heat light and heated parts.
• Touching the heat light may result in burns.
• Touching heated parts for a long time may result in burns.

NOTICE:

Do not heat the rear bumper assembly excessively.

3. Install the rear corner ultrasonic sensor retainer in the position shown in the illustration.

NOTICE:

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

HINT:

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

(b) The orientation for the RH side is the opposite of the LH side.

3. INSTALL REAR CENTER ULTRASONIC SENSOR RETAINER

NOTICE: Perform this procedure only when replacement of the rear center ultrasonic sensor retainer is necessary.
