We had the ESC light come on in our 2016 Promaster 1500. Our cruise control stopped working as well. Read a few threads that recommended turning the steering wheel all the way to the left and then all the way to the right and repeat this 3 times. We put the vehicle in park at a gas station, performed the 3 cycles of turning the steering wheel while the vehicle was running, left the steering wheel all the way in the far right position at the end of the 3rd cycle and shut the vehicle off. Turned it back on and drove around and the ESC error message was gone and the cruise control was working again.
