Whether or not the blind spot sensor itself is damaged, if the rear fascia comes off, a calibration is called for.

Using both the sophisticated electronics of Hunter’s ADASLink diagnostic scan tool and old-school measurements with string and a plumb bob on a 2020 Mazda 6, Joe Keene demonstrates that the key to all ADAS calibrations is precision – and particularly so with blind spot sensors. ADASLink’s onscreen instruction ensures that precision by eliminating guesswork and providing an accurately performed and thoroughly documented calibration for more than 25 million vehicles.
