I'd be surprised if the service brakes are activated without the pedal being pressed. Yes, I know radar (adaptive) cruise control systems do that and so can those pre-collision things, but that's different than a computer dragging the brakes down a grade. How do they know when to "let off" so they don't overheat? Temp sensors in the brakes now? I can't see that being the case.
I think the exhaust brake slowing the truck activates the brakes lights as they are programmed to do.
I am 100% certain that my Ford operates the truck brakes, trailer brakes, brake lights, exhaust brake and transmission shifting automatically when the auto exhaust brake is selected. It works extremely well.
NOT doubting you but why didn’t the Ford slow the load as well as the RAM?
