I got a 99 grand prix gtp. The ABS light and traction control light is on and the cruise control stopped working. I scanned the car and got a few codes, B08896, B0450, B0550, P1571. I went ahead and cleared them to see if they would come back and they did. Could these be the speed sensor in the hub? The last time I cleared these codes off the lights stayed on. I am assuming the cruise control won't work with these lights on? Any suggestions?
