    참고
    If the harness clip is missing or unclipped, replace or correct the harness clip and replace the ultrasonic sensor. Otherwise, continue to the next step.
  7. Inspect the LH Ultrasonic sensor alignment to carrier. Verify that the sensor contacts the sensor carrier and is not crooked.
    Informational PurposesAn informational icon, calling your attention
    참고
    If the sensor is misaligned, replace the ultrasonic sensor. Otherwise, continue to the next step.
    Informational PurposesAn informational icon, calling your attention
    참고
    The ultrasonic sensor must be centered in the sensor carrier opening.
  8. Lightly press on the back of the LH Ultrasonic sensor. Verify that the sensor does not move in farther towards the inner door surfaces.
    Informational PurposesAn informational icon, calling your attention
    참고
    If the sensor moves, replace the sensor and check spring installation. Otherwise, continue to the next step.
    Informational PurposesAn informational icon, calling your attention
    참고
    The tapered end of spring must be pointed away from sensor when installed.
    Informational PurposesAn informational icon, calling your attention
    참고
    Spring tension may need to be increased by manually extending the spring.
  9. Perform a wiggle test on the LH ultrasonic sensor. Verify that the sensor does not rock back and forth or twist side-to-side.
    Informational PurposesAn informational icon, calling your attention
    참고
    If the sensor moves, replace the sensor. Otherwise, continue to the next step.
