Hey... I am stuck with my tech magic. Since months I have issues with my Stability System and ABS. Randomly the ABS kicks in during braking, randomly the TRACTION ACTIVE kicks in during low speed acceleration, resulting in loss of power. Sometime the "Service Stability" is shown, and in the next moment it has disappeared and all is back to normal.
DIAG CODES SHOWN:
C0035 Left Wheel Speed Sensor Circuit
C0035 Right Front Wheel Speed Sensor Supply
C0455 Steering Wheel Postion Fault
Strange to have C0035 with two different root causes!?
I have replaced both front Wheel Hubs and both front sensors twice! After that it was okay for some days. The Steering Wheel Position Fault was checked in a Cadillac/GM shop. It works fine. I also cleaned the ground mounted to the chassis below the driver seat.
Any ideas what I can do? Its totally random and the faulty ABS activation will result in a decreased braking performance before the ABS light is shown and the complete ABS system gets deactivated. This is giving me a bad feeling to let my pregnant wife drive the car. Suddenly the ABS light turn off and all is okay. Sometimes, sometimes not.
The problem is, that I am based in Germany, and here is no one with real expertise on these older trucks and parts have high shipping costs. I am working on US trucks since years but I never had such a difficult problem to solve. Its my first GM after many Jeeps, Rams and Fords. The main problem is that all this happens totally random as I have mentioned. I just did a 2000 miles road trip without any problem and I thought that I beat the problem after changing two ABS sensor for the second time. Next day to work, my truck showed his demon again.
If you have any ideas, let me know please!!
