Service 4wd light and a light to the right that looks like traction control is on . Because of this i have to press the brake pedal in order to shift from park . The cruise won't work either while the light is on which is 99 percent of the time. 4wd high still works but not in low. Any ideas of what it may be would be appreciated. The dealer is a last resort cause i like to fix my own . 2012 ram 1500 5.7
