I have a 2010 Ram 1500 5.7L V8 Hemi with 90k miles on it. We were headed up a steep bouncy rocky road and my wife flipped the 4x4 on. This is when the light came on and 4x4 indicator just blinked. After on level ground the light stayed on and has the same blinking indicator and won’t shift to 4x4. The codes came back ECU DTCM Code: C2201 description FDCM/DTCM Internal. I have an appointment at the dealership in a week but want to get some advice? Thoughts?
