Default High idle.

Took truck (l5p)to dealer and asked it they could program my high idle and they told me thereís no cal avalible for it yet ??

Fun fact: truck was low on coolant and they said itís cause I took a long trip and coolant level will go down after a long trip, I was like never heard of that but noted

Good luck on getting the dealer to program it for you. i tried 3 times even had the bulletin and they did not want to do it.

On the low coolant, there is a tech bulletin on the L5P where they system needs to be filled and re bled due to an issue during MFG.
