INSTALLATION

CAUTION:

• Check sonar sensor packing for damage before installation.

• Check that the packing is properly installed to the sonar sensor.

• Install it so that the connector of the sensor turns to the arrow direction of the figure.

Center sensor

Install in the reverse order of removal

• Install in the reverse order of removal when install only the sensor.

• Follow the procedure below when replace the sensor holder.

CAUTION:

Never reuse the sensor holder. Always use new sensor holder when removing and replacing sensor holder and/or rear bumper facia.

1. Hook the pawls to install the sonar sensor to the sensor holder.

   

2. Degrease and clean the inner side of the bumper fascia base line and then apply primer (3M K500,K520 or equivalent) on the sensor holder installing face , which is shown as on the figure.

   

   CAUTION:

   Never apply two coats of primer. Applying two coats or more of primer results in excessively thick film and this may allow the sensor holder to come off from primer under exfoliation.

3. Dry the primer for more than 3 minutes and peel off the double sided tape releasing paper (film) and then taking precautions not to contact the bumper with the double sided tape ( on the figure), bend the sensor holder to the arrow direction as shown on the figure ().

   

   CAUTION:

   Primer drying time depends on temperature and therefore confirm that primer has dried before bending the sonar holder.

4. Match the sonar sensor part shown on the figure, to the sensor installing hole of the bumper fascia.

   

5. Remove the sensor from the sensor holder and press the adhesion face ( part on figure) throughout with your thumb for more than 2 seconds and pressure bond the sensor holder [Target pressure: 50 N (5.1kg, 11.3 lb)].

   

   CAUTION:

   • When the temperature is less than 15°C (59°F), use a drier etc., to warm the adhesion face and proceed the work.

   • After installing the sensor holder, leave it at least for 2 - 3 hours.

6. Hook the pawls to install the sonar sensor to the sensor holder.

   

7. Shake the part of the sensor holder shown on the figure up and down and then right and left to confirm that the holder has been installed (bonded) firmly.

   

8. Connect connector to the sonar sensor.

9. Install the rear bumper. Refer to Removal and Installation.
