MX – Sensor – Ultrasonic – Rear Door – LH

Sensor – Ultrasonic – Rear Door – LH (Remove and Replace)

FRT No: 11334202

Special tools required for this procedure:

Supplier Part Number Description
1080580-00-A Heat gun
1080603-00-A Infrared thermometer
1080978-00-A Force gauge
1080978-10-A 22 mm diameter tip for force gauge

Removal

  1. Open the LH front door. Open the LH rear door to a comfortable working position.
  2. Ensure that the LH rear window is fully closed.
  3. Remove the rear door closeout panel (refer to procedure).
  4. Disconnect the electrical connector from the ultrasonic sensor.
  5. Twist the cap clockwise to remove it.
    Note: When the cap is removed, the spacer and spring might fall out of the sensor carrier.

    6 Butyl patch
  6. Remove the spacer and spring.
  7. Remove the ultrasonic sensor from the carrier.
    Note: Inspect the face of the sensor; ensure that the adhesive that affixed the sensor to the door was removed with the sensor. If the adhesive remains stuck to the door, use a plastic trim tool to remove it.
  8. Discard the ultrasonic sensor.

Installation

Caution: The ultrasonic sensor is a one time use component. If the ultrasonic sensor is removed, a new ultrasonic sensor must be installed.
    1. Attach the 22 mm tip to the force gauge.
    2. Connect the electrical connector to a new ultrasonic sensor.
    3. Ensure that there is sufficient slack in the electrical harness to prevent it from pulling on the sensor when it is installed. Reposition the harness as necessary.
  1. Use alcohol wipes to clean the sensor mounting area on the door panel.
Caution: The ultrasonic sensor and door panel must be at an elevated temperature for proper adhesion. Read this section fully before continuing. Perform steps 5-10 without stopping.
  1. Use an infrared thermometer to check the temperature of the door panel. If necessary, use the heat gun to heat the door panel to at least 25 degrees C (77 degrees F).
    Caution: Do not continue this procedure unless the door panel is at least 25 degrees C (77 degrees F).
  2. Use a spring clamp, bar clamp, or similar tool to gently hold the sensor with the coupling tape facing up.
  3. Aim the infrared thermometer at the face of the ultrasonic sensor. Use the heat gun to heat the face of the ultrasonic sensor to 45 degrees C (113 degrees F).
    Warning: Wear heat-resistant gloves when performing this operation.
  4. Remove the protective film from the coupling tape on the new sensor.
  5. Install the ultrasonic sensor.
  6. Use the force gauge to apply a force of 55 N to the sensor for at least 10 seconds.
  7. Reinstall all components that were removed for access.
    Note: When reinstalling the spacer, ensure that the flat side faces the sensor.
