Default PSM Coding

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 mo air leaving the caliper at either bleeder. 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.

Buy the thinkdiag pod off Amazon. It will program the PSM correctly. Other scan tools sometimes dont have all the correct options.
