Fast idle??

[dshogman]

Talking with another member of our caravan to Newfoundland about diesels. He asked if I used the fast idle when starting up to get the air bags filled more rapidly. He turns the cruise control on and presses "set" and the idle goes from 750 to 1000. Tried it and nothing happened. Do we have such a feature, fast idle, on our coaches?
Thanks from Twillingate!

Hi David,

I do pretty much the same: Turn On Cruise Control, put foot on accelerator pedal and rev to about 1,000 RPM. Press Set. The engine revs at about 1,000 RPM until I turn off the Cruise Control via the Smart Wheel button.

It sounds like your caravan member eliminates the step of 'putting foot on accelerator pedal'. I'll have to give that a try next time I'm in the rig.

Cheers!

Push cruise control "ON/OFF" and "SET" buttons at the same time on your Smart Wheel.

On mine you don't need to push them at the same time. First the on/off button, and then either the set or resume button. No need to touch the accelerator pedal. But you do have to keep your foot off of the brake, of course. That would cancel out the cruise control.

My 05 works exactly the same as Jim's. Turn it on and push either the set or resume buttons. Just touch the brake to release or hit off.

By the way, if you have either a to high or to low idle, I have the procedure to reset the idle RPM from the driver's seat.

Why fast idle? Problems? Dangers?

My 2003 has an idle adjustment switch at the left control panel to change the idle speed. I'll have to try the CC too.

Push off/on & then resume will give you 750. Hit resume again and you will go to 1000. Kick it off with the brake or turn the cruise control off.

Dangers? Don't redline it.....

On my '01, cruise is on at engine start. No matter how many times I push resume it gives only 800. But that's not bad! Why is this an undocumented feature, I wonder -- not on the VIP smartwheel site either.
Batman: It fills the airbags faster.

On my 400 ISL I don't have to push On and Set at the same time and don't put foot on accelerator to get to fast idle.

I recently posted with related question and some of these responses might be of interest to you:

When the oil pressure comes up I hit the resume button on the smart wheel and it goes to fast idle.

It also does other desirable things, apparently. Go to the Cummins Engine Forum and read the thread: How long do you wait before using Fast Idle.

Here's a procedure I ran across that may -or may not - work with Alpines as it does with Monaco:

I thought I was having some issues for almost a year when I would come to a stop at a signal or pull into a campground and my coach would idle rough, shaking cabinets and doors. I found if I pushed on the accelerator a smidge, I could bring the idle up about 50 rpm and everything was smooth. Just by accident I read a thread on how to adjust your idle on at least the ISL. When the cruise control is OFF, increase or decrease your idle speed by pushing on the SET to raise and the RES buttons to lower your idle speed. Each push raises or lowers your idle speed by 25 rpm. Once you have it set where you want it, turn the crusie control ON and it will permanently set the idle at that speed. What I found over the years was that I would hit the SET button for fast idle, but hadn't turned the cruise control on. Unknowingly, I just lowered my idle speed by turning the cruise on and trying again. After doing this a few times I ended up with the rough idle.

As mentioned read the thread on the Cummins engine forum. I have done lots of research on it, it's advantages and downfalls. I don't want to repeat myself here about it.

To turn it on - so no one is confused. Start coach, allow oil pressure to come up for 20 seconds or so, push the "ON" button and then the "SET" button on the smartwheel, and fast idle will start. Mine holds at around 900 RPM.
