Hello group! I've been having problems with the ABS, DSC, and 4x4 systems for a while now. The error appeared suddenly and without any prior signs. I've already replaced the ABS sensors and the CV joint rings/tone rings (on the driveshaft/axle) but it didn't solve anything. I had the car scanned and it indicates that there might be a missing contact/connection (or an open circuit/signal loss). But I don't know where the problem might be. Have any of you encountered this before?
