I recently had to have my windshield replaced in a 2020 Nissan Murano. I was charged to have me ADAS system recalibrated. I don't think my ADAS system was accessed or recalibrated. I assume the ADAS is recalibrated through the (OBD-2) diagnostic port. Is there any history that I can check or someone can check to see if this system was recalibrated?
If it's anything similar to flashing the ECU, a dealer level scan tool may be able to do it. I think dealers use very high level scan tools to check and see if the computer was re-flashed after coming into dealerships if the engine blew up, etc. Deep within the ECU's programming, may be a tracker of sorts that detects how many times the vehicle was re-flashed so they know that the vehicle's rev limiters, etc were bypassed and then flashed again to make it appear like it was covered under warranty.
