Well, pins 2 and 10 expect a high voltage of 5v, pin 2 expects 7v, and the can bus lines expect a voltage differential of +2v , so if pin 5 and pin 15 are earth, then all of these connectors are expecting a low voltage and are being presented with 12v.......
As I said, I don't know what *actual* damage this would do but I imagine one of three scenarios.....
1) Nothing happens, reader cannot connect - scroat moves on.
2) Reader displays error - scroat decides van has issues and moves on.
3) Reader is damaged and stops working - Confused scroat moves on.
It is unlikely that scroat will realise what has happened.
Worst case - van is left alone. Best case van is left alone and scroat needs to buy a new reader.
Actually, I suppose the worst case is that scroat realises what has happened and decides to smash up the van in revenge, but this is highly unlikely. Typically he will be relying on getting in, starting the van and disappearing with it quickly and quietly. I would expect that faced with a van that won't connect he will panic and leg it.
