Seat Control Module Coding

Working through setting up heated seats in my car. I matched all options on seats, swapped in correct head unit, swapped seat control module and airbags in to donor seats from original seats, ran all necessary wires, and VO coded the 494 option. Then coded REM, FEM_BODY, HC2, SM2 and IHKA3 ECUs using ESYS 3.27.1 and psdz data 4.19.21.

The passenger seat is now working, however, I cannot get the driver seat to work. If I swap in the seat control module from the donor seats, I am able to get both seats working (so I believe that all of my wiring is good and the head unit is good), but with the donor control module, it throws airbag lights.

Based on the searching I have done, it seems I need to either code the original seat module to have heated seats or code the donor seat module to accept my old airbags.

Any thoughts or input is greatly appreciated, I've hit a wall at this point.

Thanks in advance!
