Hey everyone, I have a 2014 T680 with a paccar mx13 with about 700k miles. About a year ago I noticed an issue where I would turn the key so that the truck could run through all it's checks before starting and the ABS(tractor) light would stay illuminated along with the def guage showing empty(tank was full) and the truck would not even crank. All I had to do was turn the key off and then back on again to clear the issue up and it would be fine. It would happen very seldom like maybe once every other month. Lately it has been happening more and more often to where it's almost every week but it hasn't been consistent enough where I can get it to happen in front of a mechanic to diagnose it. Any one else have this issue come up? I'd at least like to go into the dealership knowing what the issue may be so any insight would be greatly appreciated!
