Toggles

power divider and locking rear.

 

I believe it disables the abs system when you are off road/ gravel/ muddy surfaces, and maybe snow. I haven't spent much time looking in my owners manual. I will dig it out and see. yup, that's what the manual states, disables ABS system. PDL as everyone has stated is the interlock for the diff's, ENABLE/ OFF Road disables the ABS System

 

Question about the PDL switch. Going down the road it starts blinking even though it's unlocked. Dealership couldn't figure it out. Doesn't do it all the time, but randomly starts blinking. Thoughts?

 

It can be programmed to disengage at a certain road speed. If you are above that set road speed with the switch engaged, I think it will blink.

 

The only problem with that is that it is turned off when it starts blinking.

 

Gonna start a new thread since my ? is kinda off topic.

 

Wrong switch, but good find on the manual.

Per the original post for ENAB/Off Road:

Generally, an OTR driver will probably never use it. For normal use the light is off. To disengage the traction control push the top of the switch so the light comes on. I use mine somewhat frequently as I do oilfield/construction/heavy hauling and spend a lot of time off-road.

What it does is turn off the traction control so you can get the wheels to spin. This is necessary in mud and very deep snow, otherwise the traction control prevents the wheels from spinning and the truck won't move.

A pet peeve of mine is WTH doesn't International group similar switches together and in the same place every time. For very muddy conditions, I will engage the PDL, both diff locks and disengage the traction control. All those switches control related functions so it makes sense to have them together on the dash, but noooooooo. We have operated something like eight Prostars over the last two years and not one of them had all the switches together and none of the trucks have the same switch placement; even ones that are identically optioned.

 

if the wires are long enough you can pop out the switches and rearrange them. I did with mine
