Okay I went through the analysis with my Brother who is a master Mechanic and we deduced that the ABS/DSC control module is faulty. We used the scanner to check the readings at the wheel. I had two codes saying that the wheel speed sensors at the left front and right rear are defective. So we hooked up the scanner, went into live data and we could see that 3 of the 4 sensor channels were reading but the right rear one had no communication. We swapped the rear sensors from side to side and no reading was detected to the right rear wheel. So the sensors are good but a fault lies between the DSC module and wire that feeds to the sensor. Anyway we change the ABS/DSC module and VIN coded it to the vehicle. We left the scanner connected in live data and immediately upon driving signal communication was achieved from all four wheel sensors. So ABS /DSC unit defective. Keep in mind the while the ABS/DSC unit was defective none of the usual suspects of lights came on as had been discussed in some of the Xoutpost discussions (for instance triangle warning, ABS light, etc.). The vehicle would just go into trans fail safe mode and then the SES light.
