I have a 2016, 2500, Cummins with approximately 54,000 miles. I am traveling back to the Northwest from Arizona, and am pulling my travel trailer. The past couple of days while pulling a grade, around 2400 rpm's, the Perform Service light is popping on, stays on a second or two and turns off. This happened again yesterday while backing my travel trailer into a spot in the RV park. I would appreciate any input on the potential problem.
