Need Help coding a PSM

[Dllrd23]

2009 Cayenne S-
Just swapped my PSM/ABS module with a used unit with identical part numbers. *Old unit had a hydraulic pump error and the pump would not run. *After replacing, the pump can be commanded on but when I scan for fault codes (Autel Maxis Elite) I get a code 1044 module not coded properly. *When I go into coding, I chose 17" and 18" Brembo - I have 18" wheels. *I do not know if it is MSR or non-MSR and I do not know if it is HSA or non-HSA. *Frame is coded as Steel. *Can anyone help with the HSA and MSR as to what they mean and what selection I should make. to get this code to clear.

Additionally, I seem to have a small amount of air trapped somewhere in the system. *Pedal is firm on first brake application but if you let off and immediately reapply, it will fade under constant pressure. *I used a pressure Bleeder (push) and bled rr,lr,rf,lf. *Still had air but no air leaving the caliper at either bleeder at any caliper. *I manually bled the PSM module by opening the input Lises (2 of them) after assistant pumped up the pedal. *Then I did the same on the 4 output lines. *Then I rebled with pressure bleeder. *I cannot find an automated Bleed anywhere. *Any suggestions would be greatly appreciated.

ABS module may have air in it. You must bleed it with a scan tool capable of "opening" ABS "valves" (or whatever there's inside). You can't bleed the brake system with air in ABS the old way.
