Engine/Transmission (1998.5 - 2002) Cold weather High Idle

[dewey88]

Can anybody tell me if you can get this done to a 6 sp, or is this only available on autos? The dealer that I deal with told me that it was not available for my truck, but my buddy just bought a 04 and his has the 6 sp and his has the high idle on it! My truck is a 01 6 sp HO. Thank you for the info!

I know of @ least 2 6speeds that have it working. Both these trucks are 01's.

Mine works just fine thank you!

Has anybody had this done around the Michigan area? Just wondering what dealer I should take it to to get this done! Or should I take it directly to Cummins in Grand Rapids?

I have an 2002 6-speed. I had to hand the dealer the TSB and argue with them that such a thing existed. They gave me a "you don't know crap" look when I told them about the 3 cylinder high idle. It was like I was their first informed diesel customer. Since, they have given me respect since they've learned the hard way a couple times that I can spot their b. s.

Woah, who put me up on that soapbox...



Anyway, 6 speed, works great, really warms the engine up fast. Keep in mind that the 98. 5 to 02 idle program is not as intelligent as the 03 and up. The 03 and newer models base fast idle on ambient air temperature, meaning that the 3rd gen trucks will idle back up even when at full temp after being parked for enough time in air temps cold enough. As for the 2nd gen 24 valve engines, the high idle program is based on intake manifold temp. Once the engine is at full temp, no matter how long you park it and let it idle, it will not return to fast idle on its own. The 2nd gen fast idle program only starts when the intake manifold temp is below a set temperature.



And of course, there are many other factors that have to weigh in before a CTD initiates its high idle program, like zero wheel speed, service brakes not pressed... blah blah blah.

high idle

It is standard in all HO's. The dealer can't find how to load the software in because it is already there. They have to use the DRBIII and go into the engine controls, Misc menu and enable 3cyl idle. I made six trips to two dealers where I was treated like an idiot and informed they had worked on these trucks for 25 years and knew them inside and out. On the last trip I finally got the tech to look for the setting. When he went to the menumentioned above he was still claiming 3 cylinder idle wasn't there. When I pointed it out, he said, "Yes, it's there, but it's diasbled!" That's when I said "I know that! That's what I've been trying to get you to Enable!" He said somwthing nasty and then clicked it, and the choice to enable or disable popped up. Witt nothing left to say, he enabled it. Two mornings later it was cold enough and when I started the engine it idled normally for about 15 seconds and then ramped up.

The problem is the TSB doesn't say anything about the HO's. So when they search for it, it won't show up. Just print out a copy and bring it to the dealer.

That's exactly what I'd like to do, but I can't find the TSB.



Does anyone have an address where I can download it?



Thanks

High Idle

I just called another dealer near me and asked them about it and they said they have never heard anything about it also! But he did say bring it in, in the morning and they will take a look at it and see what they can do. I have printed off the TSB sheet and am going to take it over there with me in the morning! Thanks again for all the info everybody!

can you enable this on a non-HO 2001. 5?

Thanks. Now I see my problem. There are two different "cold idle" threads going. One here and one in the 3rd Gen Forum.



I'm looking for the TSB listed in this thread:

Yes, starting in 2001. 5 thru 2002 the program is already in the computer on all trucks and just needs to be enabled. On my 2001 it needed to be loaded first. I think step 7 starts the process they will need to use on your truck in the TSB

I already have the standard high idle. AFAIK, it comes already enabled on '03 - '04 trucks. This other one uses the cruise control to ramp the idle up to 1500 RPM to improve warm-up.



Here's a quote from DTR:



"Did the flash and enable for the cold weather idle today on a customers 04. Talk about a great option! After flashing his controller and turning the function on with the DRB it worked perfectly. This feature works like this. Start the truck up, turn the cruise on and push set. The idle immediately ramps up to around 1000. Push the accell/resume button and you can increase the idle up to 1500. Touch the brake pedal and idle returns to normal. The bulletin applies to DR trucks ETC or ETH auto trans with an engine serial number **57130284** or earlier, and the engine date of manufacture on or before **December 10, 2003**. "



This TSB is supposed to be number 18-004-04, but I can't find it.



Thanks again. TDR is great!!!

I had the dealership near me do it this morning, and they went directly off the bullitin that I printed off of here. So I hope to try it out in the morning and see if they new what they were doing! Thanks again for all the information everybody!!!!
