I have a 2011 ram that just recently started to give me some trouble. Truck runs perfectly fine but when you go to shut it off truck will keep running with the key in your hand. I will have to stall it to shut it off. Once truck is off my trailer brake controller will beep and say CF. When I go to restart I have no glow plugs and when it fires up my exhaust brake is in the on position. Truck has p2509 code stored for intermittent pcm power. If I unhook battery’s for about 10 min truck will operate perfectly for about 5 to 10 on off ignition cycles then will start all of this. I hope someone can point me in the right direction this thing is driving me nuts!! Thanks in advance!
