2nd Gen Non-Engine/Transmission Hi Idle

[Moe]

Any member in the 740 (east central Ohio) area that might have a Smarty for a 2nd gen that would be able to turn my high idle feature on? I called the dealer in my town and asked if they could do it and found out they have never done it before. Now is not the time for them to learn on my truck. Willing to pay for your time and knowledge. Thanks, Moe.

I don't believe you have anything to "turn on. "

The high idle feature was not offered until several years later when the ECMs were enlarged with greater capacity. I don't think even the early HPCR engines offered the feature.

My '06 had it and now the '08.

Moe, when was the last time you had your truck into a dealership for any work? Chances are, they may have reflashed your ecm with the latest software when they did, its prett commonpractice. Then again, if youve had your truck through a cold winter and its never idled up, thats a good indication yours is not yet programmed. Where are you located? Im in Ashtabula county (very northeast corner of Ohio)

When the 98. 5 to 02 trucks were built, they did not have a high idle feature. Sometime soon after(not sure when) dodge realized they needed a high idle in cold weather and came out with a tsb. I will look later for Moe to try to find the TSB number and and he can take that number to any dealer and they will be able to flash his ecm for the high idle feature

That's the same one that will give the 3 cyl high idle when temps are down around the single digits, right???



My '98 had that enabled, really got your attention if you were standing by the truck when it shifted to the 3 cyl mode... . :-laf

You are correct. And yes the 3 cylinder high idle will get EVERYONES attention when it goes off :-laf I can enable my high idle and 3 cylinder idle with a series of resistors and a toggle switch i installed. The resistors makes the IAC see a colder temp and will fool the ecm into high idle mode. This time of year its a nice feature to have.

The reflash TSB 18-019-01 is what I was asking about. It is available for 24valves built after 1997. Looking at the archives I found someone there who said it could be done with a smarty. I am south of Canton 35 miles. Thanks, Moe

 

[JR]

Your correct Moe it can be enabled with a smarty. Im really surprised that the dealership couldnt help you out since you have the TSB number. I have a smarty and would be willing to help you out, but we are a pretty good drive apart from each other. It takes me an hour and a half to get to Canton, from the sounds of it we are about 2 hours away from each other. If you cant come up with a better alternative, shoot me a pm and I may be able to drive part way down and meet you somewhere.

I had a dealer add the high idle function to my 2001 HO. The first dealer was obviously pretty clueless, and because I got the TSB info off the internet they didn't view it as legit. The next dealer said they'd give it a try for their standard ECM reflash rate, which was an hour of labor. They "followed" the TSB, but I ended up having to bring it back to have them actually enable the high idle feature.



Basically, any ECM update after 9/2001 has the high-idle software built in but not enabled. So the first step of the TSB is to flash the ECM up to the latest revision. Then the next step (the one my dealer failed to do) is to go back in and enable the high idle feature. Basically, if they follow TSB 18-019-01 it will work.



The catch with the high idle feature is that it is activated at 32* (15* for the 3-cyl idle) according to the intake air temp sensor, when the key is first turned on. If the truck is cold-soaked to those temps, it will work as advertised. But even a couple mile run to the corner gas station puts enough heat in the block that it won't enable the high idle after shutting the truck off, even if the temp guage hasn't moved. I've even come back to my truck after sitting for four hours in 20* temps and the block wasn't cold enough to trigger the high idle. If you plug in the truck it'll never trigger. So, it's not a perfect system, but it's better than nothing. Wire in a set of resistors and a switch like diesel4life and it becomes much more useful though.

 

[Moe]

Its just that my local dealer has never done one. Im going to print out the procedure and let them read it and see what they say. Thanks to all for your replies. Moe

 

[Moe]

Maybe diesel4life can show us the mod with the resistors. It would be worth a try.

Once you get it enabled I hear lots of good things about this. .

Fast idle is also great in the summer to increase a/c output and decrease cool-down time after towing.

You really like answering questions you have no clue about don't you. .

I havent looked at the link AH posted, but that is the website where I got all the info from to do the mod. Mike is a very knowledgeable guy over there, and very helpful as well.

There has always been. Little confusion between the selectable and the automatic hi idle. Every dealer has access to all tsb's. All the have to do is go to tech connect and enter the vin or year,model,engine. Some may not want to because the old hardware is not as nice as the new system To know if a flash is available they just have to enter the current software # and wait a couple seconds for the answer

I got a feeling I will be ordering one. It will come in handy. I have the program already, but when it is warmer outside I was putting a stick on the accelerator pedal to bring the RPM's up in the morning. Thanx.

Wait until he finds out idle up with the curise buttons is available for a 98. 5.

Is this a little sarcasm? Or are you serious? Ive got a 98. 5 and youve got me interested!

Yeah, I occasionally learn I was very wrong or didn't know something but I've never been dumb enough to state here in the TDR forum that Cummins inline six cylinder turbodiesel engine produce peak torque at 2500 rpm. You win the grand prize for that one.

I bought a new '01 HO/six speed in about June of '01 and became a member here shortly after that. I drove that truck 325,000 miles and was an active TDR member all that time except when I was on the road during '05 through '07. I even bought and installed a manual high - idle kit made and sold here in TDR sometime in late '01 or early '02. I don't recall anyone here knowing the ECM could provide high idle during that period. Can anyone provide a link to an old thread where that was discussed?

No sarcasm, Dodge actually has TSB's describing the addtion of the idle up feature and steps to add it to all the CR and 24V engines. Are those TSB's still good? Are they still providing support for them? What exact CC os speed controls are compatible? That is the $64 question(s).

In addition to that, these engines were used in rollbacks, wreckers, fire trucks, etc, that had modules that activated the idle up to 1500 rpms when the installed equipment was in use. According to the company that built wreckers and roll backs they has a module that plugged into the harness that activated that when the equipment was in use. I didn't buy the truck I was looking at and moved so never went back and pursued that particular solution.

The PTO function is inherent in the ECM and harness. Getting the right component and making sure the ECM is activated correctly is the trick. If cost is no issue the solution is easy.
