I’ve had some issues with my LML Duramax. A couple years ago I replaced the batteries and replaced the alternator twice. Second time was an upgrade from a 150 amp alternator to 220a I believe. After replacing the alternator a couple years ago I went on a road trip, when I arrived at my destination, truck wouldn’t turn off even with the key out of the ignition. Had to remove two 5a microfuses. Those fuses go to 2 Upfitter switches. Down to this day if I put them in, the truck wouldn’t turn off. It runs fine, but i’m now having a separate issue with different codes talking about NOx sensor circuit high output. Recently had a Shop diagnosed my downstream nox sensor. I replaced it with a brand new ac delco. My diagnostic tool is not really recognizing it, unless it was faulty is just not showing any levels on live data. I am getting a P0381code permanent showing glow plug heater indicator circuit. Was thinking of replacing the module but now I wonder if I can put a single darn part on my truck without having to take it to the dealer. I recently even get a temporary code showing water in fuel which I drained and there wasn’t a drop. Could it be something as simple as my water in fuel sensor with the plug? I’m grabbing at straws here but feel kind of helpless when I take it to the dealer. Oh yeah, The whole reason I replaced the nox sensor is because i’m getting a service exhaust system notification on the dash and I am in limp mode for several more miles before four mph. Was going to try to do the repair, then service regen.Any thoughts?
I'm needing to program a glow plug module on a 2013 Silverado 3500 HD 6.6, would this software be what you recommend? I have both the Snap-on and Autel scanners with a j box, both give me the option to set the inj flow rates, however, it is not possible to program the actual module using these scanners. Do I only have to set the inj flow rates ? Or do I also have to go the route of laptop programming in addition to setting the flow rates ? Do you know of another route to take in this situation?
Is this for an aftermarket module? Or an oem replacement? I keep getting code PO674 and was just gonna order a new module since I just changed my glow plugs maybe 10k ago I'll test them before I do the module also.
I am an independent repair shop using an aftermarket pass through j2534 device. You must log into Acdelco tech connect, download their software and buy a pass through device. A mongoose cable is the inexpensive way to do only GM, then a laptop, check gms website for compatibility on the laptop you want to use. Then a $55 subscription. It’s complicated and if you don’t know what you are doing you can “brick” your module ultimately rendering it useless.
Wouldn’t it be easier to find a used module that matches your LML and skip the programming. GM is obnoxious with all the programming bulls**t. The reason I avoid working on them
Problem is, it’s a common issue so the chances on getting a faulty used module is high. Plus shops and customers want to fix a problem once. Not over and over since the used module might not last very long.

Is it possible to program the module using either the Snap-On or Autel scanners?
I see the mongoose Pro cable from $148-$482 are the ones for $148 a scam?
I have an LP5 2018. Is this the same way to reprogram?
This method can fix DTC code : "DTC P133E: Cylinder 7 Glow Plug Offset Exceeded Learning Limit" ? My truck 2019 gmc duramax

how do you program you 2013 ? i got the same problem right now !!!
@@juannava4092 I don’t recall, it’s been a while. Sorry I can’t help.

This is a brand new OEM module
My question is. Is that a GM dealership only programming. Or is there an aftermarket scan tool capable of this proses

Thank you
What if you got a used unit from eBay. Will it be plug and play?

@@jaylooney1477 Good to know it’s a common issue. Thanks for the video and follow up 👍🏻
