Drive Mode and Steering Personalization without Switch

[marinalin85]

That IHU code it's a "throwaway" code you see sometimes when programming, can just clear codes and it will be fine. The PSCM code, though we are missing the translation info, it's a "U" code type, which is specific to "communications" in the car, so it's probably nothing to be concerned with, if it's just a leftover after programming. Clear those codes and that should be it.

If you have buttons or features missing, that will be be related to the coding you have done, you made a change to a setting that caused those options to disappear. I guess in this specific case, those buttons may be incompatible with enabling the drive mode selection, unless the drive modes (Eco, Off-road?) cover what those discrete virtual buttons used to do, something Volvo added when removing the drive modes. That's my guess anyways.

Mine was the same the first time I tried it. Then revert and tried again a week later. Let the car reset and I got the Drive Mode button
Same happened with ACC/PA. First time nothing, second time got them
