The BCM and ECM just see a resistance that is dependent on brake position. I'm going to have the computer modules on my 2019 Venice checked next week. That might shed some light on the brake light problem. Might want to wait about spending money at the Chevy dealer on recalibrating the sensor until I can report.Looking forward to whatever you learn, but also have to wonder if there are any differences in this area between the 2019 and 2018 models, since Vanderhall seems to make a lot of unannounced and undocumented changes, even in the same model year.
