  6. REMOVE FRONT SIDE ULTRASONIC SENSOR RETAINER

    Tech Tips


    • Perform this procedure only when replacement of the front side ultrasonic sensor retainer is necessary.

    • When removing the front side ultrasonic sensor retainer, heat the front bumper assembly and front side ultrasonic sensor retainer using a heat light.

    • The illustration is for the LH side. The orientation for the RH side is the opposite of the LH side.


    1. Heat the front bumper assembly and front side ultrasonic sensor retainer using a heat light at the specified temperature for 3 to 5 minutes.

      Heating Temperature
      Item Temperature
      Front Bumper Assembly 40 to 60°C (104 to 140°F)
      Front Side Ultrasonic Sensor Retainer

      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.
