Look in the Drivetrain problem area lots of them, problem with your activator motor

Can you tell me more about it Ive looked in all the other forums but im getting confused because of other codes and ect.

The motors have issues mine kept turning on the service 4 wd system light and took it to the dealer they would just reprogram the computer. The code means the Computer can not tell what postion the motor is. The final result is replace the actuator. I personally think that water gets into it and shorts it out( that's my opinion)

Thanks MichiganSilver03 for the info I'm going to try the fuse thing and see if I need a re programing I havent had the problem where it automatically shifts to other modes.

I have heard that you pull the fuse, turn it on(do not start) erase the codes, turn it back off fast, replace the fuse and it will relearn the position. I heard this works, have not tried it.
