Thread: This is kind of technical

Well I am going to buy the relay and see if it works I will let you guys know if it did or didn't still trying to figure out the second missing relay but I will go to the dealership and see if they know

I typically leave it on, but it doesn't come into play usually. I normally will be crawling slower than the 5mph anyway.

Check the operator's manual. It'll probably say what they are for.

Probably for the oil cooler and something to do with hill decent control.

FDII has a higher output alternator. Probably needed to power those extras.

Turning the ESP full off keeps the HDC from working. I prefer it that way myself, although maybe on steeper looser hills it might be handy. I've been going down hills off road for a long time though, and prefer the way I drive to the vehicle doing it itself. It makes a lot of noise too when HDC is working on the downhills.
