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?

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.

      2021 vs 2026 handling (1500 X31 Sierra)

      By dennismc · Posted

      I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it.

      frustrating P0446 code

      By Old Bay · Posted

      So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
