I was reviewing the data around the DTC event, and it said the hand brake was on. I assumed it was a software bug, because I was sure the hand brake was off, but today after jacking up the rear I noticed that there is ever so slight drag on the brake pads with the hand brake off. The wheel is spinning but there is a sound of slight friction on the brake pads. So how does ECU tell if the hand brake is on or off? The car is Alfa Romeo Giulietta 2011.

There's a switch under the centre console at the front of the handbrake lever.

You can see this in videos such as this one (no affiliation, I found the video when looking for info about the cigarette lighter)
