Found this posted in the main Alfa thread. Will add it to the front page.
In case anyone wants to add the factory powered side steps and does not want to pay the dealer for the added sales code here is what I changed in AlfaOBD. Took about 24 hours for the soft key on the 12" screen to show up and the settings option. Also when you deploy or retract the steps a little notification pops up on the gauge cluster.
I've attached photos of the 3 areas that were enabled. Cabin Net-PSSM Power Side Step Module; Cust.Set.Menu 3-Power Side Step Enable/Disable CSM Present; Cust.Set.Menu 2- Automatic Side Step CSM Present.
