i am looking at enabling the high idle on my truck with winter coming up. the question i have is:

by enabling the high idle, will the 3 cylinder idle also be enabled with this or is that a seperate option?

thanks for the help, Pat

I beleive they are seperate toggles in the ECM.

Going to get mine done as well before the cold hits.

When they reflash the ECM the high idle and three cylinder shut down are done at the same time, it's all one program.

Remember after they reflash the ECM they have to go back in and turn the program on. The default in the program is set to off so it has to be enabled for it to work. Some have had the reflash and it did not work because the tech forgot to change the default setting.

Since you have an 02, chances are you don't need a reflash, just have the tech hook up the DRBIII and then check to see if its "disabled". I forget which menu it is under off the top of my head..........

Does this have to be done at the dealer, or can it be done ourselves or elsewhere? I am not that happy with the local dealer.

Edit: I am not even sure I need it or not, or if it is available on my truck. How do I test for it?

I want to know more about the high idle option. What do we need to enable it? Any wiring or switches needed? How does it work?

I know on my friends frieghtliner he hits his cruise control and it high idles for any set speed on the tach!

I want to know more about Cummis though....

I know on my 01.5 I only needed to enable the feature with the drb, no flash required. This would be the same on the 02. On older trucks you had to flash update the ecm first and then that would allow you to enable the feature with the drb scan tool.

Here is some info from Dave Fritz' site for the reflash.

NOTE: THIS BULLETIN APPLIES TO ALL RAM TRUCKS BUILT AFTER DECEMBER 17,1997 AND EQUIPPED WITH THE 24-VALVE 5.9L CUMMINS DIESEL ENGINE.

Discussion:

This bulletin involves selectively erasing and reprogramming the Engine Control Module (ECM) with new software (Cal 55Tl8, 57Tl1, 56Tl3, 59T7b, and 59T8b.)

Symptom/Condition:

Extended idle operation, especially in cold weather, can lead to stuck valves and bent push-tubes due to insufficient cylinder heat. This allows varnishes/oils to condense on the exhaust valve stems, leading to stuck valves, and damaged valve train components. A new software feature, enabled or disabled through the DRB III (See instructions under Repair Procedure), reduces the chance of valve sticking and improves cab heat warm-up time.

Once enabled, idle speed will slowly ramp up from 800 rpm to 1200 rpm when all of the following conditions are 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

Additionally, if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters above are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change in engine sound which is normal. This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and cab heating.

Both features will automatically disable when one of the following occurs:

1. The Automatic Transmission is placed in gear (forward or reverse) or,
2. The Service Brake pedal is depressed or,
3. Throttle position is greater than 0% or,
4. Vehicle Speed is greater than 0 mph or,
5. Coolant Temperature is greater than 79°C (175°F).

Engine speed will return to normal operation at 800 rpm. If the engine continues to idle and coolant temperature is at or below 60°C (140°'F), the feature will reenable. In order to operate properly, the Accelerator Pedal Position Sensor (APPS) must stay at idle.

NOTE: ANY TYPE OF AFTERMARKET IDLE SPEED KICKER THAT ACTIVATES THE APPS WILL DISABLE THIS FEATURE.

Use of the 110V block heater will not allow the feature to function after an overnight soak. If the vehicle is left idling, without use of the block heater, 1200 rpm operation will begin when the intake temperature drops below O°C (32°F) and coolant is less than 60°C (140°F).


Additional info is available on the TSB, but this is the basic info.

am I correct in saying the service brake is also known as the parking brake? if so, will I need to chock my tires to keep the truck from rolling when the high idle is enabled? since my truck is a manual and the high idle is cut out when in gear or the parking brake is engaged, how else am I suppose to keep it from not moving?

i need some help with this one, Pat

J BODY

Sorry, didn't note the manual trans. It may not be available on your truck. I know it's not on the newer ones (04 up).

DSjockey

I think the service brakes are the regular brakes not the parking brake
How much should we expect to pay at a Dodge dealer to have this done?

Barney

DC says they will pay for 0.5 hours of labor in the TSB. So, I would figure about 1 hour at whatever your dealer charges per hour of shop time.

Mopar1973man

Anyone here in Idaho with a DRB III scan tool?

I would be interrested in getting that ENABLED on my truck!
