Cruise control will not engage with switch in on position, it feels monintaryly to try to set then cancels. Also after driving several minutes the message center displays fail safe and cruise control switch will turn off.. there are no check engine codes, engine runs fine, and all brake lamps work ok and vacuum leaks at throttle body. Also can i connect OBD 11 and drive vechicle untill fail safe warring appears on message center and then run code check and clear codes

Yes do not if all you have is a code reader. I was talking about a diagnostic scan tool. I recommend you take it in and have a Trained Tech diagnose there are many possible faults and via internet not able to solve.
