NECESSARY PROCEDURE AFTER PARTS REMOVED/INSTALLED/REPLACED

Replaced Part or Performed Procedures	Necessary Procedures	Effect/Inoperative Function When Necessary Procedures are not Performed	Link
Disconnect cable from negative (-) auxiliary battery terminal	Memorize steering angle neutral point	Parking assist monitor system	Refer to INITIALIZATION [06/2020 - 10/2022]
	Memorize steering angle neutral point	Panoramic view monitor system	Refer to INITIALIZATION [06/2020 - 10/2022]
Kick door control sensor	Reset connection history	There are cases where the connection history display differs from the vehicle condition	Refer to DATA LIST / ACTIVE TEST [06/2020 - 10/2023]

If the bumper is damaged, there is a possibility that the installation area of the blind spot monitor sensor may be deformed and the blind spot monitor system may not operate correctly, so visually inspect the blind spot monitor sensor installation area (frame, stud bolt) to make sure it is not dented or bent.
Refer to ADJUSTMENT [06/2020 - 10/2023]
If the visual inspection finds a problem, check the installation condition of the blind spot monitor sensor, and adjust the installation position of the blind spot monitor sensor as necessary.
When the rear bumper is damaged or deformed due to an accident or contact with other objects, etc., or the bumper installation area on the body is repaired, it is necessary to perform ultrasonic sensor detection angle measurement.
Refer to CALIBRATION [06/2020 - 10/2022]
