I would like to run the motor at idle in my 2021 Silverado to charge the battery in my RV. The motor shuts off after a short while. How do I defeat this. Thanks, Mick

You have two options as far as I know.

 

Either stick the truck in neutral and apply the parking brake or ask about this service from the dealership that you will have to pay for.

The Techline Customer Support Center will provide programming instructions and changes to the vehicles calibration settings. You must provide the vehicle identification number (VIN) of the vehicle to be programmed. There is a fee associated with the requested vehicle calibration changes.

 

Refer to the proper Body Control Module: Programming and Setup procedure within SI.

 

Important: If this calibration is installed, the dealer will need to print the Owner’s Agreement Statement attached in this bulletin and put it with the Owner’s Manual.

Might want to make sure the exhaust doesn't enter the RV. If your parked with the engine running for hours in a camp spot, it could happen. As far as the auto shutoff defeat, I would try to get the computer pre-programmed to not auto shut down. Mail it off, get it back in a couple days. Maybe $50 fee. Oh, and since your computer is being programmed anyway - have them disable the DFM for free.

I think you should add about $600-800 at a minimum to that $50 fee, there is no such thing as a cheap tune for a new truck like this. You can't just mail the computer off either, doesn't work that way with new truck.

 

HP Tuners would be very expensive way to go about this, plus it voids the warranty.

 

The dealership service is the cheapest and easiest option for fixing this problem forever.

So your saying that reprogramming would work, but the who and the how much it would cost are the variables?

Is the idle timeout a newer thing? Never heard of that before.

Yes it started with the 19s and push button start. Since you don't turn the truck off by removing the key. It can be left running without you knowing. It has happened before and people have died because of it. So now there is a timer to automatically shut off the engine after a period of idle.

After the automotive industry killed a few people that left push button vehicles idling in there enclosed (and attached) garages....

I guess if people can forget their kids in the car. And need a warning device for that. Taking your family out by leaving your vehicle running in the garage isn’t much of a stretch. Put in park hit the button. Take a leak, pull up the zipper. That’s another tough one. Hard to imagine there’s people that absent minded.

  It would cost GM less than a dollar to add a carbon monoxide detector somewhere inside or outside the vehicle on all the push button vehicles. So if the rig is left running in the garage, the horn starts honking, or some other sound, and it also triggers the automatic engine shut down (as long as the vehicle is not moving). Maybe a voice that repeatedly and loudly says "DANGER: CARBON MONOXIDE DETECTED, DO NOT ENTER GARAGE, EVACUATE HOUSE IMMEDIATELY AND THEN CALL 911". It would have a manual bypass or something that resets after 30 minutes, to allow for vehicle diagnostics and repairs or what ever.

 

If it cost $1 per unit, and they make 250 million cars, than I guess it would not make financial sense to install them though - since the company would probably not be responsible for the deaths due to the fact that on page 347 of the owners manual there is a "warning" that says ... Don't leave your car running in a closed garage..   I'm sure that the few lines of print cost less than $1, so it is what it is I guess.

 

Am I right? Who knows....

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached
