on thursday i was driving my truck down the highway at about 60mph and wasnt dogging on it or anything and all of a sudden the check engine light came on, abs light on, brake light on and it said service brake system in the display. i pulled over and cleared the codes with the v2 and tryed to go again and it wouldnt go out of first gear. it had a p0700 and p0721 code and a
c0055 and c0550. i messed around with the output sensor wires and i just happened to reach up and the front driveshaft was locked like it was in 4 wheel drive. i put it in 4wheel drive and then took it back out and cleared the codes and the truck drove fine the rest of the day. but everytime you cut it off when you start it back all the lights are on and c0055 and c0550 keeps coming and i clear them and it drives fine until i shut it off again. any ideas?
