My 2017 ram Cummins doesn't delay the start even in freezing cold temperatures. Everything is turned on and up-to-date. The diesel mode is turned on. Now I will say the truck doesn't have any trouble starting, but I'm worried about the long-term effects of starting it before the preheat cycle finishes.
I did my own tests back to back mornings and used the key one day, and the dash displayed the engine preheat countdown. The next day I watched from outside the vehicle and did the remote start and as soon as the dash lights came on the truck, it starts. It does not even display the preheat countdown on the dash when it definitely should have (30 degree ambient temps).
I see in the settings there is a "20s" option. That's all the information it gives...I'm wondering if that's a 20 second delay option? If so I think that would be enough time to pre-heat the engine..at least where I live (central NC).
Any help would be greatly appreciated.
