Is anybody experiencing software problems in there recent emission delete or auto shutdown delete. I recently bought a low mileage 2015 579 peterbilt with a paccar engine. In order to reduce costly repairs from an emission problem I had the truck deleted at loadline. I also had the auto shutdown deleted as well. The problem is after I returned home and filled a trailer load of grain my enginewould shut off every four minutes or so while I was unloading in the elevator. So, I brought the truck back and they reprogramed it and worked once or twice and than quit altogether again.
Is it a problem with loadline s software or my ecm. Also loadline told me they can not delete the auto shutdown when they do the emission delete because the truck engine has to have more than 500 000 miles on it. Is that true. Just to clarify, Loadline gets a third party to reprogram the auto shutdown on my truck. Its frustrating because I paid 1600 bucks extra to the delete fee to have my engine stay running.
Loadline said Peterbilt changes software to prevent customers from changing there equipment to there special use requirements. This has right to repair your own equipment written all over this.
Any body run into similar problems with there newer farm trucks. Otherwise I really like the truck and think the paccar is a smooth running engine.

Do you have it on high idle when it shuts down?
There is no reason that the engine would have to have certain miles on it to be able to disable the auto shut down. It’s just a box to check in the ecm parameters.

My brother has a laptop with pirated software, occasionally he runs into issues where he can not access or change certain parameters, especially where key engine features are involved. Like for example his version of Insite for Cummins, he can do just about anything he wants except anything pertaining to HP ratings and such. Makes no sense if this Loadline outfit is offering deletes and then they have to bring in a third party with the laptop...sounds like it most likely wasn't done proper. Them Paccar things are also very proprietary too. Reason why lots shudder when they see one of them when they open the hood.

How in the world did you find someone that would do a delete? That's all dead in the water down here, figured it was that way up there too.

Capt,thats interesting about deletes. I think our colder climate causes more issues with the amount of heat needed to perform a regen. Most of the time a farm truck will never reach the driving time to perform a proper regen, and that is where all the problems start. Also the DEF fluid can freeze up in minus 25 to minus 35 celsius. The heaters in the DEF tank obviously dont do there job.
Has anybody heard of the 500 000 mile rule for deleting autoshutdown. It sounded strange to me but if a company like paccar is not wanting there ecm changed it could be true. Even the mechanics are frustrated with the software changes. I heard on a trucking forum if you apply the trailer brakes you can bypass or trick the ecm to keep truck idling. Also is there a temperature sensor on the autoshutdown. I was wondering if temperatures are below zero would it stay running.
thanks for any feed back.

When I was checking out some tandem trucks there were a couple where truck was idling, box up, while checking things out the engine shuts off. Kind of an issue when you need an engine to run a hydraulic pump. These were converted trucks but I wonder what a factory built truck running a pump does to avoid this issue.

Paccar=Problems from what I have seen, non-stop trips to the dealer.
My Volvo's never missed a beat for 6 years and then I made the mistake of hauling in -40C and froze the def pump. Had a guy delete them and only thing I can complain about is the coolant needs to be kept up or engine does a de-rate. Seems goofy that coolant level would trigger that when engine isn't even hot, software guys probably never ran the trucks before...
I'd call a different shop, there is one in Holland I have heard of.

Our paccar only has 550,000 km but it’s never had auto shutdown on it.

What year meskie is your truck. Mine is a 2015 , I paid 1600 bucks for the auto shutdown delete so hoping to get it fixed on warranty. Still, I am surprised its not part of the engine delete like some people say. The one thing I am afraid of is the software so called geneiouses could do more damage than good to your ecm.
I wonder what the oil and gas guys do to there pto equipped trucks. They are idling them rigs alot and a lot of them are brand new trucks. You would think an auto shut down delete would be not to tricky.
Actually lOADlINE in Winkler do alot of deletes and ship trucks all over western Canada , the dakotas and Montana. Loadline gets a third party to do the auto shut down but now I am worried he messed something up in my ecm. Man , its these problems why I dont miss using my old 1985 GMC brigadier with a trusty n14 cummins. One year at harvest I even left the brig running all night long by mistake.

Ours is a 12.
It’s just a setting in the ECM. My neighbours rent a truck for fall that’s only a couple years old with the paccar in it and it doesn’t have auto shutdown. It’s a 579 Pete as well. You could program the 60 series Detroit’s and N14 celects to do the auto shutdown as well. It’s not a new thing. You could take it right to the dealer and have them take it off. But would likely cost the same as what loadline charged.

Our ‘09 Mack has the shutdown but at least it’s set for a longer time so isn’t really an issue, if I bump the idle up it overrides the shutdown. Not the worst thing in the world, sometimes if I get home at say lunchtime, instead of sitting there waiting for the truck to cool down, I just go home to eat and let it shut off on its own. Only bad thing is the ignition stays on so if you forget about it, it will kills the battery. Have a’96 Kenworth for a grain truck, had the shutdown deleted ( or maybe it was the Freightliner? I forget) it was a two minute job at the dealer and I don’t think they even charged me for it, mind you this was 10 years or so ago. I imagine any truck set up to operate pto’s etc would have an override programmed to let it run while using the pto. Or maybe the same as our Mack when idled up, seldom is there pto work done at an idle.

My 2012 kw will shut off after 30 minutes if not idled up. I’ve been on the lap top with a couple different techs at kw stoon. The idle shut down is turned off. On or off makes no difference.

Ok so with some playing around and than checking with the tech at loadline the auto shut down work all along but the cruise has to be shut off. Problem is now the paccar motor is idling at 650rpm with auto shut down activated. I cant up the rpm on the truck without the cruise engaged. If the cruise is on and I throttle up to 1000rpm after about three minutes the truck will shut off. Seems backwards to me!
So my question is what is the ideal idling rpm for optimum engine performance and also not to high so it interferes while you can shift?

Ive been told to not idle the paccar engines below 1000rpm. All our trucks with electronic control never sit idling at low rpm. We always hit the switch to put them at higher idle. Generally around 950-1000. The paccar we have to manually set it every time its started. The dd60 and n14 just idle up to high when you hit the resume on the cruise. |
