ABS sensor wires broken

[Hong]

Hi...Anyone familiar with the wires between DSC control unit and left rear wheel speed sensor. I google a lot but get nothing. I used INPA and get three codes.
One of them is Speed Switch Rear Left Line Interruption (code 30 Drehzahlfuehler hinten links Leitungsunterbrechung).

I removed left rear side trim in cargo area to try to find the broken line and also replaced the speed sensor terminal plug. The pics will be in the following post. Thanks in advance!



Here copy the original codes:
