I've got a 2018 Ram 4500 4x4 Cab & chassis with the 6.7 and I recently started getting the Service 4WD light to come on and off. It will come on when the speedometer gets to about 20 mph and will shut off when the truck gets down to about 15-20 mph. If I start from a stop and am going down hill, it won't come until I get to a point where I need to give it fuel. Was hoping somebody may have some insight into why? I've also recently had the ABS and ESC light come on, but it normally will only stay on for anywhere from 2-30 seconds. Dealer claims it needs a new ABS Pump. Thanks!
