I have to say Im impressed, I did this work about 3 years ago and started writing a comprehensive DIY and never finished as too many questions came up about how to use FSTool/CarServer and felt that perhaps it was better to leave pandora's box closed on that one, props for putting the info out there though.
Can confirm 100% that this method (at least the certificate creation and import) works and reads/scans/codes like OEM...been that way for me for 3 years at this point.
Its nice to see the tools have gotten a little easier to find/work with at least
