High idle on at factory on '15's?

[RVTRKN]

Yes, it was ordered with the PTO option.

Wile hooking up a trailer a few days ago my high idle came on for the first time and the exhaust brake came on also.

Sounds like you were most likely experiencing a regen.

It was 40 degrees outside and the truck hadn't been running 4 minutes. I didn't think it would regen when the engine is that cold.

40*F won't engage the automatic high idle.

I am guessing at the temp but the high idle did come on. I was behind the truck when it sounded like the exhaust brake came on. When I got back in the truck and pressed on the brake it idled down and I was off. Do they idle up when they regen?

It is nothing but a simple switch to break the sense circuit. One would think it could contained in the existing neutral safety switch but who knows the impact on existing functionality. Does your truck have the idle up working? Is there only one switch on the clutch pedal or more?

I've never tried to use the idle up feature to see if it’s activated on my truck. I've always assumed that it was not as I have a '14 Tradesman 2500 purchased off-the-lot and long distance from Dave Smith... guess I should try it. I've not looked at the pedal for switches, but my truck doesn't have the PTO option (on the window sticker), I'd be very surprised it the high idle feature is already activated/functioning.

Tried it. Not activated. Looking at the BD solution.

I think idle up is not active on any 2500's. Plan to add BD TSB before the spring thaw

Correct. The manual high idle has not been available on any G56 pickups....just the automatic versions.

My 2014 3500 will also go into high idle if the battery voltage gets to low. It did it when cold,idleing with a lot of electrics on.

My 2500 has it.

Effect of too much idle time?

It doesnt get hot in nebraska? If you are gonna idle, enable high idle. But its your engine and I have personally seen what happens with idle times that are more than 20% of the life of the engine

On the manual pickups, how can the pickup know the parking brake actually works? What happens when you accidently hit it in gear? I seen why chrysler doesnt want the liabilities of it on the manual pickups

Interesting thread - read the whole thing.

Alliance, what is the typical effect on the engine of too much idle time?
