Here would be the one for your 2002

Pay particular attention to step 14, as this is the one they usually forget.

It took me 3 tries at 2 different dealers to get it to work right.

Oh my god to we have to go through this again ? TXtad, all you should need to do with your truck is to take it to the dealer and have them plug into it with the DRB. Under the misc. menu you will find the cold idle enable. Have them enable it and you'll be on your way. On some of the older trucks (pre 01 I believe) the feature isn't on the misc menu so you had to flash update the ecm so that the cold idle program could be installed. After that you had to go back in with the scan tool and "enable" the feature. For you guys with 04 and newer you can have the feature enabled by flashing the ecm and turning the feature on with the drb for the cruise switch feature. And NO the 03 common rail engine DOES NOT have the hardware for the cruise idle up feature. They still had the old school electronics so they will have the idle up feature like the BR/BE trucks.

 

I have the cold idle enhancement enabled on my truck but have found that using my exhaust brake along with it seems to work much better in warming things up. Only takes about 5-10 minutes to get to operating temp unless it's below zero then it takes about 15 minutes.

 

Thanks for the TSB link!

Mopar-man, cruise control high idle currently is only for auto trannies, option not availble for manual. So your truck no, your mom's truck yes

 

Nope, only available on 3rd gen automatics with the Cummins, 2004 and 2005
(and most likely 2006 when they happen).

His 2002 is 2nd gen.

His moms truck is a 1500, so no Cummins.

You mean, after all the talk about high priced High Idlers and sticks between the seat and pedal, all I have to do is have this flashed into the ECM? Why havent I heard this before? Why does anyone even make a High Idler if this feature is possible in stock for?

 

Thax Phox... Yea your right...

I've been using the stick in the seat trick...But I hate when the stick falls out on it's own! Sure makes it longer to warm up in the mornings! Still thinking about having the High Idle - turned on...

 

sorry my bad, better clean my screen so I can see/read better. 3rd gen with a cummins doh

 

All's good!!!

 

The stock high idle function is dependent on too many conditions being met.
1. Intake Manifold Temperature less than 0°C (32°F) and,
2. Coolant Temp is less than 60°C (140°F) and,
3. The Transmission is in Neutral or Park and,
4. The Service Brake pedal is not depressed and,
5. Throttle = 0% and,
6. Vehicle Speed = 0 mph

Aftermarket high idlers can be turned on whenever and wherever usually.

Good question.... What is a good RPM for high idle for warm-ups??? What is too high??

 

1200rpm seems to be where Cummins and Dodge like it to be.

That's where the 2nd gen and 3rd gen high idle reflashes put it.

I remember hearing why higher isn't better, but I can't remember the reasoning behind it.

Hey Phox, why not idle higher than 1200?

I've never heard there's anything wrong with doing that. I've read alot of people idle ~1400.

Do you know why?

 

I think the grid heaters kick out around 1400 rpm.
In the winter we bump winter idle up to around 1300 rpm. Cummins ECMs have lots of adjustment.
