Hi

I was checking a friends Skoda Superb from 2014, because he had some ABS issues. First of all the ABS indicator was turned on and second, some times when he breaks, the ABS system activates like when you break on a snowy and icy road, only it is summer.

I checked the car using live data on a scan tool, which showed the picture above. I thought that maybe it could be a half broken sensor. It was cheap and easy to change, so I thought that this would be a great way to eliminate that possibility. But nothing changed, so now I am considering a troublesome connection in the wires going to the sensor. But I do not have a wiring diagram, so before diving deep into a wiring system with blindfolds on, I thought that I would see if this could somehow be something else that I should rule out first?
