Did it seem fixed after they replaced the BCM? I just got my truck back last week after having the BCM replaced....so far so good....just wasn't sure if I should go ahead and tear into mine to check the ground?

Only way to tell is when summer hits. Higher temps make the BCM heat up more. After I had my BCM replaced it fixed the issue for a month then it came back. Honestly I would check that ground. It doesn't take long to get to it.

You're welcome on the post. Believe me I was pissed when my truck did this. I love the truck to much to get rid of it and I love electronics and troubleshooting things. So glad my video and posts are

Talking to a buddy that has a 2500, he said his started acting up the same way after he was messing with installing his new floor mats. Eventually found out that the ground wire runs down around the pedals....he probably bumped it while messing with his floor mats. Ironically I detailed my car and vacuumed the carpets the day before mine started acting up. Any idea if the ground wire runs down near the pedals where I could have tweeked it while vacuuming?

On the 1500 it does not run near the pedals. It goes from the BCM straight up to the top of the dash

Was told my truck "sent codes" that pointed straight to BCM.....could that truly be the only problem or should I go ahead and start looking at the ground?

Mine did the same thing. Communication errors with the BCM. Due to the voltage drop. Basically the BCM was turning on and off essentially.

So essentially this could be a problem with a every truck?

You could put a star washer under it to help it bite into the metal better giving it even better contact.

That's a great idea

I just checked my 2014 (build date June 2014), it looks like that material is already notched out around my ground. I never had any issues as described by the OP.

My how to isn't duplicate. I put it in the other sections too. This is the how to. Please do not delete it.

Instead of tearing apart your dash, wouldn't it be easier to just run an additional ground from the BCM to another part of the dash?

Any idea if I take my truck in to the dealer since I'm still under warranty and ask them about it?

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      2027 GMC Sierra: Official Discussion

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
