The TURB DAMP function uses additional accelerometers I believe, they may develop a fault which is undetected by the aircraft however detected by the pilots. I presume an option to override this was required during certification, as it modifies the Normal Law behaviour of the aircraft. I've never seen or heard of it being turned off.
I'm not sure what you mean by "scanning" switches or lights on. Remember Flying an Airbus is all about rumours and facts; any switch position is merely a rumour, what the aircraft tells you on the SD is the fact of what is going on.
