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?

Vehicle was standing for about 3 years after it was knocked on the left side front fender and bonnet. It was starting and running but would suddenly cut out and I it always take two cranks to start. About a week ago, I left it idling then it suddenly cut out and when I started it again it went into limp mode with wipers on constantly plus dsc and abs warning lights on cluster. Fuses are good and there's power to the DME. please assist been battling. Thanks
