The tricky thing about the calibration routines is that there’s no obvious indication that they’re actually required.


You can accidentally flash as a replacement, and you’ll still end up with green checkmarks . However, before SIPS proceeds to the “Fast Learn” routines, you can abort the process — and that will cause problems later on. In that case, the process is incomplete, even though everything shows .


And then you end up wondering why warning messages appear on the dashboard or why certain functions don’t work properly.
