    2010 Tahoe LTZ electrical saga, need some input... - SOLVED

    Lmao I had no idea; this was the first GM vehicle I'd owned in roughly 15 years and we never even looked into using it. Well I guess that answers that even further, haha.

    You guys are never gonna believe this. OnStar. That's it. That's the problem. Lol. More specifically, the VCIM or OnStar Modue. As with most of the other modules we've been suspecting, it's on the high speed lines...so when/if it goes, everything goes. I don't know what led him down that...

    Might have been a misunderstanding, but the mentions of mileage and such are just the general interval between incidents, not consecutive driving miles all in one shot immediately prior to failure or anything. It's done it a couple times while running, but mostly does it on startup. Has done...

    Well, we're trying the whole "test drive" thing again this weekend, lol. Made it out of the parking lot and on a few errands this time at least. Whether that's good or bad at this point, idk. He wouldn't tell us what he did this time and says he "has his doubts", so at this point I think he's...

    Well, another week later and the best of the best in this area can't figure it out. We had had a phone conversation a few days ago where he was pretty suspicious of the BCM and was waiting on another failure to confirm. But I guess very shortly thereafter, he identified another ground...one...

    2010 Tahoe LTZ electrical saga, need some input... - SOLVED

    Quick update (idk about anyone else, but I absolutely loathe when I'm reading through a thread on a similar problem to what I'm chasing and the resolution was never posted or the saga just stopped at some point. So I'm trying to be diligent about seeing this through on here.). Literally only a...

    2010 Tahoe LTZ electrical saga, need some input... - SOLVED

    I've been suspicious of actual modules from the beginning (this wouldn't be my first rodeo with failing modules in a variety of vehicles and the behavior has been similar) and it was one of the first things I mentioned, but the first two shops completely ignored my concerns and glossed over it...

    Small update for information's sake: Once the weather warmed, I did a full cleaning and re-grounding job of the two frame rail grounds on the driver's side, as well as the duo on the left rear body mount. Those four grounds ranged from "meh, bit of surface rust but still decent contact" to "I...

    Yea, someone else mentioned it and I had actually mentioned it to the last shop but was brushed off. I just crawled underneath there (now that I have it back for a couple days) and it doesn't look like there's much corrosion in there, and none of the pins have backed out, but I'll still mention...

    @Fless @Joseph Garcia Have an update for ya. After sitting for another week+ untouched with no updates (bringing us to a month now of this escapade)...I went ahead and pulled the plug. Picked it up, told him to send me a bill, and I'm going to take it to what will be a third shop on Monday...

    2010 Tahoe LTZ electrical saga, need some input... - SOLVED

    Yea, that's been my experience in the past, when it affects multiple systems and features and is seemingly random it's a module issue, usually top-level like the BCM. I just wanted to cover the simple little bases first before I took it in, but also both these shops seem to be really zero'd in...

    @Fless I have never noticed anything particularly odd outside of the normal swings from the RVC; nothing straying outside of normal patterns over the last 60,000 miles. @Joseph Garcia Yea, I plan on seeing if I can get a full list of the secondary codes next time we speak if they haven't fixed...

    Our 2010 Tahoe LTZ has been an absolute beast since we bought it at roughly 125k; it's got 188k now and I've kept it in pretty solid condition the whole time in spite of heavy usage...and have avoided a lot of the typical problems with these things. Thing still easily books for 10k in my area...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Lol, so while digging into a different problem today, I decide to scan for Enhanced DTCs on my code reader and I come across a recurring P0573. Which is strange, because we've had zero issues with the brake lights, cruise control, etc. The switch (the usual culprit) is cheap and it's like a 5...

    Throttle body relearn/high idle issues

    Wires are fine, air intake is fine, etc. I did discover that the PCV hose insert was slightly loose and pushed it all the way back in; not sure if that actually made a difference or was causing/would have caused enough of a vacuum leak to mess with the idle or relearn. Regardless, performed...
