Date: September 3, 2001 Models: 1998 1/2-2002 BR/BE Ram Trucks (2nd Gen Cummins, 1998 .5, 1999, 2000, 2001, 2002) 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 re enable. 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). Diagnosis: 1. Using the Diagnostic Scan Tool (DRBIII) with the appropriate Diagnostic Procedures, verify all engine/transmission systems are functioning as designed. If other Diagnostic Trouble Codes (DTC) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. Parts Required: Qty.

WHEN USING THE MDS2 AND THE DRB III, THE SYSTEM MUST BE OPERATING AT CIS CD 2090 OR HIGHER (2090 ARRIVES IN DEALERSHIPS ON SEPTEMBER 3, 2001). Repair Procedure: 1. Log onto the MDS2 (Mopar Diagnostic System). 2. Connect the MDS2 and DRBIII to the vehicle and switch the ignition key to"ON". NOTE: AUTO CONNECTION WILL OCCUR ONCE THE DRB III, MDS2, AND VEHICLE ESTABLISH COMMUNICATION. THE "CANNOT READ VIN FROM DRB III" MESSAGE (ON THE MDS2) WILL BE REPLACED BY THE VEHICLE VIN. PRESS THE "OK" BUTTON ON THE MDS2 TO REQUEST A L4DS2 SESSION FOR THE VEHICLE VIN INDICATED. PRESS THE "OK"BUTTON WHEN ASKED TO BEGIN SESSION. 3. Push the FLASH tab on the MDS2. 4. Select READ PART NUMBERS FROM VEHICLE and click SHOW UPDATES on the MDS2. NOTE: A MESSAGE MAY APPEAR (AFTER STEP 3 OR 4) THAT INDICATES NO UPDATES ARE AVAILABLE. IF THIS OCCURS, MAKE SURE YOUR DIAGNOSTIC EQUIPMENT IS OPERATING AT THE LATEST SOFTWARE LEVEL AS LISTED EARLIER IN THIS BULLETIN. IF THE LATEST SOFTWARE IS INSTALLED, AND NO UPDATES ARE AVAILABLE ANOTHER VEHICLE CONDITION EXISTS THAT WILL REQUIRE FURTHER INVESTIGATION. 5. Select the new software part number with the light pen and click UPDATE CONTROLLER SOFTWARE. 6. The MDS2 and DRB III will prompt for any operator action needed during the remainder of the reprogramming process. NOTE: DUE TO THE PCM REPROGRAMMING PROCEDURE, A DTC MAY BE SET IN OTHER MODULES (EATX, BCM, MIC, SKIM, ETC.) WITHIN THE VEHICLE, IF SO EQUIPPED. SOME DTC'S MAY CAUSE THE MIL TO ILLUMINATE. ALL DTC'S RELATE TO A LOSS OF COMMUNICATIONS WITH THE MODULE THAT IS BEING REPROGRAMMED. CHECK ALL MODULES, RECORD THE FAULTS, AND ERASE THESE FAULTS PRIOR TO RETURNING THE VEHICLE TO THE CUSTOMER. ERASE ANY FAULTS IN THE PCM ONLY AFTER ALL OTHER MODULES HAVE HAD THEIR FAULTS ERASED. NOTE: ONCE THE VEHICLE HAS BEEN REPROGRAMMED TO THE PROPER SOFTWARE LEVEL, YOU MUST USE THE DRB III TO ENABLE THE 3 CYLINDER IDLE FEATURE. TO DO SO FOLLOW THE INSTRUCTIONS BELOW. 7. Connect the DRB III to the vehicle without connecting to MDS2 and follow the menu structures it appears below. 8.

Mopar1973Man.Com the Mopar1973man.com High idle switch is sold through the Forum Store. you can get to that product and others through this link If you are having problems getting the High Idle enabled on your truck you may rent a Smarty from Diesel Auto Power. Smarty Rental For High Idle Enabling View full Cummins article

Operating Instructions Once the high idle kit is installed its ready for use if the ECM has had the High Idle Feature Enabled, the Dealer can enable this feature, or a Smarty can flash the High Idle into the ECM. There is a Dodge TSB Covering what needs to be done, Dodge High Idle TSB You can view the Install Article Here, mopar1973man.com High Idle Switch Install you can buy a High Idle Switch in our Store - General Operation It's always suggested you set you high idle mode before starting the vehicle. This will insure you going to get the selected mode of operation. If you want to leave it totally automatic high idle then select OFF as it will follow the ECM software for selection. So you should select either 3 CYL or 6 CYL mode before starting. NOTE: Selecting a high idle mode will enable this mode and remain the set high idle mode for the rest of the key cycle. Off OFF is completely stock ECM sees engine coolant temperature and intake manifold temperatures normally. MPG Mode MPG mode is a special mode design around extreme cold operation. During winter time the IAT temps will fall to very low temperature. This typically advances timing quite heavily and create quite a bit of engine rattle at cold engine temperature. MPG mode tricks the ECM into believing it's summer time and retards the timing down to a usable level. Most people report at least 1-3 MPG gain from using this mode. NOTE: Pre-heat grid heater function is disable in this mode. IAT is 143*f ECT is a pass through 6 Cylinder Mode 6 CYL high idle is a special mode in which it was fixed to remain in high idle mode as long as the switch is left in 6 cylinder mode. So this makes it an excellent function for like jump starting other vehicles or keeping vehicle warm in sub-zero temperature. As long as the switch is on 6 Cylinder mode it will not cancel. NOTE: Engine temperature gauge is disabled during the use of this mode. IAT is 23*f ECT is 140*f 3 Cylinder Mode 3 CYL mode is automatic mode. It will enable the 3 cylinder high idle but will cancel the high idle mode once 170°F of coolant temperature is reached. IAT is 14*f ECT is a pass through Selecting High Idle Mode While Running This is possible but not suggested. If you do opt for this make sure to rotate the knob fast. If you turn the knob too slowly the switch will break the circuit on the IAT sensor for too long and might trip the P0113 code which is IAT voltage too high. It also possible to get the wrong mode of high idle from this issue. So you may select 6 cylinder but end up with 3 cylinder. It is not recommended or supported to use high idle positions other than Off or MPG when the vehicle is in motion. Canceling Selected High Idle Mode The only way to cancel a selected high idle mode is to turn off the engine and wait 10 seconds and start again. This will reset the high idle mode. Be sure to set the proper mode you wish to start with either OFF, 6 CYL or 3CYL before starting. Please note that once ECT temps reach full operating temp the switch can be turned to off and the ecm will not longer high idle. Safety Systems All safety system are still in effect for canceling. Speed greater than 0 MPH Automatic transmission place into gear Service brake pedal pressed 170°F coolant reached (unless 6 CYL mode is used) Enhanced Warm Up For owners with exhaust brake you can enhance your warm up time to under 10 minutes. Select either 3 CYL or 6 CYL modes and set your exhaust brake on. The exhaust brake combined with the high idle will produce higher EGT's which in turn warm the engine faster. WARNING: Owners with larger than stock injectors be aware EGT's can climb rather high in 3 cylinder mode and can be as high as 1,000 to 1,100°F with a mere +50 HP injectors. You can see the switch in action, notice the ECT and IAT sensors changing values. View full Cummins article

Check this out. It makes "Obama Care" a joke. http://www.angelusnews.com/news/national/cost-and-conscience-why-more-christians-are-ditching-health-insurance-for-this-a-9920/#.VqbDd15VKlN

Yeah but, that river flows from somewhere inland...

Yuck... Damn Midwest silt.

Now you know you need to go to your friend house and steal his off his truck. Tell him he don't need it.

If the truck is parked you can use 3 CYL or 6 CYL mode only. If the truck is moving or being driven then you can use OFF or MPG mode only. You cannot use 6 CYL or 3 CYL modes while the truck is moving. 6 CYL mode fools the coolant temp really low so the high idle can start. Which it cannot start because the speed is above 0 MPH and TPS is above an idle. Using either one of these modes will degrade MPG numbers.

That right there keeps the rain from pouring into the engine area.

Being a 12V fuel shutoff relay is located on the cowl on the driver side about 1/3 of the way over. What make the difference is if the relay is hung up-side-down which will allow water to leak into it. Also if your missing the cowl weather strip this problem is worse.

If you had a way to drag it down here to me I more than be willing to drop a engine in for you. I've got the tools, the shop and even the hoist for it. You find a long block I'll stuff it in for you.

Between weak batteries, bad battery cables and failing alternator with excessive AC noise will create your issues. Alternator AC voltage should be roughly 0.01 to 0.03 AC volts, marginal is 0.05 AC volts complete failure is 0.1 AC volts and above. Bad battery terminals and cables can be tested by doing a voltage drop test. As for the batteries they need to be load tested. If any fails replace both.

Kind of like my Innova scan tool. http://pro.innova.com/Product/FullDetail/f968c286-07ab-46b7-bfd5-bae40673742e http://www.amazon.com/Innova-31603-CarScan-Scan-Tool/dp/B00D2I0IDG

Come to my neighborhood there is so many people without jobs and on welfare it would make most people sick to look at. I was helping a friend that works at the local Chevron Station and they closed down early on the shop side at 2pm because no business. Let's say for the day day they made less than $100 in sales. Business is not going good locally at all. Unemployment is very high here. Friend of mine that lives in Walla Walla WA his wife just lost her job as a Manager at the Taco Bell and now been reduced to normal worker because she was making too much money and corporate couldn't pay her any longer. So, either had a choice get fired or get reduced. Another gent I went to look at a vehicle admitted to being super slow and they really need the income from the fishing torment that is coming soon.

Until you attempt to unhook it and do a injection pump.

Been in the 40s for most of this week and majority of the snow here in the yard is gone. I'm glad I was getting tired of the ice skating rink of the front porch to the driveway below. My lower back is still reminding me about those few close calls.

Debt free here.. Everything is pay for. No loans outstanding...

Drive shafts if factory will be sealed units no grease zerks. I tend to like the slightly tight number tad bit quieter engine and seem like the exhaust brake works just a bit better. Measure at the BATT stud on the alternator and the case or passenger negative terminal. 0.01 to 0.03 AC Volts is normal. 0.05 AC Volts is marginal strange things might start to occur like lock up issues randomly. 0.1 AC Volts is a fail.

$2.279 the last time I got fuel here in Riggins, ID about 4 days ago.

4WD only has 3 zerks. Two upper ball joints and one track bar. You can try my Crankcase Vent Mod. Fairly easy to build and works very well. The only thing I didn't see is valve lash. Take the time check the valve lash. Then take another quick moment and check the alternator for excessive AC noise. I'm like you I want to make it to the moon and back. I've got 257k on the clock now and the Moon is only roughly 238k. So I'm on my way back home now.
