Notes

Two different procedures by model year; results on 2020 trucks are less well documented.

Back up every module's As-Built data and keep the files somewhere safe.
Connect FORScan with a battery maintainer on, ignition ON and engine OFF.
Open Configuration and Programming, choose the BCM module, open As-Built Format and edit only the digit described by the source.
Write, follow any module reset prompt, cycle the ignition, then confirm the feature and check for new trouble codes.
