Installation
CAUTION
The ultrasonic
sensor is a one time use component. If the ultrasonic sensor is removed, it must be
discarded and a new ultrasonic sensor must be installed.
- Attach the 22 mm tip to the force gauge.
- Use IPA wipes to thoroughly clean the sensor mounting area on the door panel.
- Use a spring clamp, bar clamp, or similar tool to gently hold the new sensor with the coupling tape facing up.
-
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°C (77°F).
CAUTIONDo not continue this procedure unless the door panel is at least 25°C (77°F).
- Remove the protective film from the new sensor.
- Use a heat gun and infrared thermometer to heat the new ultrasonic sensor to 40º–50ºC (104°-122ºF).
-
Install the ultrasonic sensor
onto the LH rear door panel.
CAUTIONWear appropriate PPE to prevent personal injury.
- Use the force gauge to apply a force of 65 N to the sensor for at least 30 seconds.
-
Reinstall the spacer, spring, and
cap to secure the ultrasonic sensor.
NoteWhen reinstalling the spacer, ensure that the flat side faces the sensor.
-
Connect the electrical connector
to the new ultrasonic sensor, and then attach the harness clip to the ultrasonic
sensor carrier.
- Install the LH rear door closeout panel. See .
- Connect 12V power. See GUID-A117E9B7-7439-40B1-A0E3-A1FD6750011B.html.
- Press and hold the close button on the LH B-pillar until the LH rear door fully latches.

long cable over the rear bolt of the front lifting pad under the vehicle.
-
Attach the cap of the target tool
short cable over the front bolt of the rear lifting pad under the vehicle.
-
Reposition the target tool so
both cables are taut, and then move the target tool cable ring up to just above
