Yes that's RT6 diagbox/telematics/repair/download you need load .cal to restore your unit
you can also do this offline to load .cal via psaflasher or other exe (but you need to have proper .cal offline )
sure this can work on bench you just need simulate bsi frames on can
disadvantage of this without bsi you have 125kbps only speed where you need share with simulation tool and send command (until you use proper tool like canalyser + vector)
better is to use bsi + Btel and use obd
