This is more a general question than specific to any vehicle or even any make.
My understanding is that when an OE or aftermarket Blind Spot Sensor is installed on a vehicle it has to go through a calibration procedure (which varies from manufacturer to manufacturer and even vehicle to vehicle). But I’m not sure what the calibration procedure is actually CHECKING. In other words, if an AM sensor passes the calibration procedure does that strongly imply that it’ll work just as well as the OE sensor?
Or does passing the calibration just tell the system “This is what something that’s 5 feet away looks like and this is what something that’s 20 feet behind the vehicle looks like… etc.” If it’s this, I could see where an AM sensor might pass the calibration procedure but then function far worse than the OE because it can’t handle bad weather or is only good at detecting a vehicle coming up from behind but not when the vehicle merges into your blindspot from the far-left lane.
I tried Googling this but couldn’t find anything definitive. Feel free to post links for me to read - I’m happy to learn more through reading articles.
