2011 Ram 1500,85,000miles, ABS,service 4x4 and traction control lights all three come on only when temp. outside get's above 50 degrees then go back out after a while or when temp goes back down. HELP.

 

Need to hook it to a scanner and find out whats bugging it.

 

I put a code reader on it and all it say's is "no codes shown".

 

If the various lights are on, there is a problem. The cheap code readers simply may not be able to talk to the correct modules.... Given the three lights that are on, I would suspect a speed sensor issue. Which one becomes the question.....
