I had the exact same issue, my 2005 C6 started giving me pretty much ALL the warnings. BCM for my year and model ordered. It will be installed next week. According to the technician, those symptoms are 99% the BCM damaged.

Just a FYI, but not hard to pull the Board out of the BCM case to give it a good electrical contact cleaning, and check for any cold solder joints on the board causing the problems.
Hence board is solid state, so an intermittent BCM problem is screaming either corrosion across a board trace, or cold solder joint instead.
Note, top drill the two silver sleeves to remove the mushroom flaired tops of the sleeves, then you can unsnap the case to pull the covers to get to the board.
When you bolt the red connector back in, it going to draw the sleeve tight to hold the cases together over just the side snaps.
Dano523 and Supertamme have some excellent posts. My question: I have bought a NEW BCM for 2006 Corvette. To program it is what I need to do is:
Buy a TechII scanner,
Pay $40 for GM subscription
Is this all I need? Does the Tech2 scanner only work with Windows XP? (that won't work with me). If I buy the Tech2 scanner (about $300) will it include software needed?
Any help is highly appreciated.

VX gm nano for around $100 (ITS A MDI CLONE).
Cracked version of Tis2000 to run SPS in a VM shell, and your done deal in 5 mins flat to program in the new BCM.
As for the tech II clone (long/more expensive way around), unless you have a laptop that has a serial RS 232 port on it, will need a USB to serial port cable to connect the tech II to your laptop to run TDS. (about $30 and comes with the needed driver as well)
the disc's you got with the clone tech2,should be ''tis2000'' programing dvd's,,load them into the laptop,and you might get lucky and have your vin on them,the disc's ive seen got to ''late 2007'' and a little of early 2008 [but its hit or miss sometimes]
you might not have to use ''GM SPS'' online
What a hassle after realizing that there are steps that mandate that you load the Tis2000 software on a Windows XP operating system. At least, that's what I understand and who uses XP anymore? So, if I want to go the Tis2000 software route that evidently means that I have install a virtual XP program on my Win10 machine. Also, my laptop doesn't accept CD's so that there is yet another headache. Thus, I bypass all that and pay the subscription $40 to use TDS on my Win10 laptop. Of course, I had to purchase a USB-serial cable also. Dano523's info is invaluable.
But now, it appears that my Windows 10 machine isn't modern enough as it's only generation 4, i5 processor? The Tis2Web won't download. So, after weeks and weeks I still have roadblocks. My gosh, I'm so committed now ($300 for Tech2, $40 for USB-serial adapter, $40 for GM subscription) and so now I guess I'm going to have figure how to install the Windows Virtual XP on my laptop (can't wait to see what glitches, probs with that!) Does this require one now to purchase an Windows XP license? I don't know. Anybody know?
AC Delco tech confirmed that my laptop is no good for running Tis2Web. Must be gen 6 intel processor and have 256 GB hard rive. Also, must be "business grade" computer. Geez. He claimed also that AC Delco doesn't support Tis2000 running on XP Windows but I think I misunderstood but....maybe not. I see AC Delco site has been recently updated 2020.
I should have called AAA to tow my 2006 Corvette to the dealer to flash the new BCM----much less hassle and cash! To top things off, the company that I bought a tow hook from sent me a $100 hardware that doesn't line up with my bumper bolts even though it's supposed to fit 2005-2013. Arrgh!
I've always been a DIY'er but first time dealing with auto computer modules, scan tools, and stuff.

If VM player will load on your machine (I5 should be a multi core precessors), then will send you a copy of my personal registered TIS2000 already loaded in a XP shell, to flash the car. Will just give you a down0load link to it, so will not need a cd/DVD player to load the program.
As for TDS, if you do have win10 on the machine, should not be a problem installing the needed software to start with. Hence what messages are you getting that is not allowing the Needed TDS software to load to start with? Most of the time, the only thing you have to do above and beyond is get Java/TDS allowed on the machine to load correctly, and the rest should be a snap.
First, thank you for contributions to forum! No problem---I did install the VMWare app that you sent. Geez, I was researching several other virtual apps---this one seems less complicated to install. So, you say you have Tis2000 in Windows XP shell? Does that mean no need to install an XP license and other steps? Wow.
I haven't be able to use the TDS software on two Windows 10 machines, my 2007 desktop Win 10 machine and a HP laptop with only 128Gigabyte Hard Drive. When I get to the "Start SPS" button I click it and wait and wait---nothing. It won't load. I get a message that I'm missing an app inorder for TDS to operate. I don't think I have Java but isn'tthat supposed be offered up when installing TDS? (at least, I saw a YouTube video where it did) The AC Delco rep didn't like my specs on laptop at all. Said hard drive was too small (128 GB), i5 generation is only gen 4 (s/b at least 6) and griped that it's not an "enterprise" grade or "business" grade. Supposedly, also are picky about Windows 10 Professional OS but I think that this is particularly important if you want tech support from AC Delco. They remote operated my machine and said it's not good enough. I'm assuming that TDS doesn't load because of outdated CPU but what app am I missing? I'm trying to install an app (TDS) and it comes back and says I need another app. What?
LATE EDIT: Success! You talking about Java got me to thinking. I was expecting TDS to install it but I just now dowloaded Java and TDS is downloading on my crappy laptop that the AC Delco tech person wouldn't even simply tell me to install Java. So, I will attempt to reprogram my BCM later and and will update this post. I'm assuming I don't install the "J2534 wrapper" and that only if Iuse that newer scan tool,right? I understand not to install the drivers for MDI and Tech 2. But, what is the J2534 wrapper? Do you install that. There's a warning that not installing it risks malfunction.
I SPOKE TOO SOON!. Now, I'm having problems again with Tis2Web. Java is not working right. I have to experiment around. Geesh. Keeps on saying that the Java installer is still installing,. Headache #3. II actually got pretty far into Tis2Web but when I restarted it probs. (more coffee please)
I do have the Tis2000 discs that ChinaCardDiags, the Chinese Tech2 clone seller, sent me but I don't know if it's all complete and good. I do have a optical drive on my desktop. I could still use the Tis2000 software, no, to do more than on TDS or is everything available on TDS as is on Tis2000 with the Tech2?
Your help is appreciated.

Yes on the J2534 wrapper install.
Should be a step to allow Java to load a few needed pages (as well as TDS as well) that you have to allow in the machine.
Hence the first time you clicked on SPS, should have had you loading the needed software from the start, then each step as the software was loading (like Java), should have had you allowing a few sites/file to your machine as well.
On the TIS200 disc, will need to have VM ware to build a shell to start with. Hence shell gets first built on XP OS (so would need a copy of that to with licensees), and once you have the working VM XP shell, then a matter of loading the discs onto it, then doing the crack and building any needed drivers as well.
Mucho thanks for all your help. I rec'd the PM's and am eager to go on the offense with this business again. I shall post again as I will have plenty time come tomorrow (Corona---no job since March) to take on this. Corvette needs to rumble.
Dano523---I got sidelined and will post my experience in reprogram my BCM when I can get back to my Corvette. Thanks to you I have everything. Kudos for your fantastic information! This is first experience in dealing with vehicle computer modules---I had NO idea that to be an auto mechanic nowadays requires a lot of computer programming or knowledge how to interface with modules. Even, for example, to bleed the brakes----geesh. Long gone are the days of always getting greasy working on vehicles.
Just a FYI, but not hard to pull the Board out of the BCM case to give it a good electrical contact cleaning, and check for any cold solder joints on the board causing the problems.
Hence board is solid state, so an intermittent BCM problem is screaming either corrosion across a board trace, or cold solder joint instead.
Note, top drill the two silver sleeves to remove the mushroom flaired tops of the sleeves, then you can unsnap the case to pull the covers to get to the board.
When you bolt the red connector back in, it going to draw the sleeve tight to hold the cases together over just the side snaps. https://youtu.be/3q83U5xPxzA
Dano523, was wondering if you had more details or videos on the BCM cold solder joint issue. My 08 C6 will throw a bunch of dic errors and go into limp mode after hitting a big bump. The problem gets worst after I wash the car. I am going to check for water leaks as suggested in some of your other post as soon as we can turn the outside water on in the spring in NY. Thanks for all of your great posts.
BCM has two edge peen sleeves that hold the case together.
When you drill the peen rolled edges off the sleeves, make sure to do so on the Top of the BCM, One of the rivets at the connector, needs the threads in take.bottom of the rolled edge in place, since the when connector is reinstalled and its bolt tightened, it will be pulling up on the bottom of the rivet sleeve peened surface to the bottom of the case.
As for cold solder joints, most of them will be at the header connector pins to board. The board is solder bathed to solder the parts all at one time, but since the header pins have more metal and would take longer to heat up to allow a good solder joint, sometimes the bath is not long enough, and this causes the cold solder joint problem at the header pins to board itself.
If you can not spot the problem on the board once you have it in hand, then post photo's of both sides of the board, with good enough photo details of the solder joints that we can see if they are good or bad to begin with, as well as maybe a burnt diode or resistor as well.
2006 base C6, I picked up a brand new BCM and am wondering if there is somebody in Sacramento area who can help me program it. I have account the GM SPS programming paid up. I can't get my TechII to work with Pass-thru and maybe it's defective unit. The car has been sitting in a garage for about a year now. Anybody nearby have the set-up and wlling to help me get thru this? I can make it worth your time.
Long overdue update: I ended up swallowing my pride and set up AAA tow to dealership. Got a telephone quote of $175 from Epic Chevrolet for the BCM flash/programming. Then, corvette carefully towed (tow prep takes extra time for low profile) and await service rep, told price is $350 even after arguing lower on phone with somebody else. Really? What to do, arrange tow without service? Of course, I've always heard about dealerships squeezing for extra. Waiting in lounge get word that techs can't program because battery is defective, not holding enough voltage. Surprised, as I had recently purchased AutoZone and, negligently, assumed good voltage and didn't check with meter. Paid for dealer install new battery, Techs programmed the BCM and I finally got resolution!
Then install VX manager 1.8.4, Firmware and license update the nano, Install Tech2win crack with the nano connected and VX manager still open, then go into VX manager apps and install Passthrou/GM GDS2/T2w, and SGM RDS apps inside VX manager.
Now install Tis2000 like you would on an XP system.

On last thing, and if you have Hackitosh on your machine under VM workstation Pro, don't be in a rush to upgrade to workstation Pro 16.
In Hackintosh, you need to us Vm unlocker and the version that I am using of it (2.1.1) does not play well with Pro 16.
Maybe VM unlocker 3.0.2 does work fine with pro 16, but in the mean time, I have stepped back to VM workstation pro 15 using unlocker 2.1.1.
Tech2, connected to a computer with TIS2000's SPS and a GM subscription.
Or, with MDI or Tech II (Either used in pass through mode), and TDS SPS with subscription instead.
So for you to do it yourself without a full GM subscription, will need either a tech II, Mdi (clones will work) or a VX gm nano (which is a clone of a MDI).
Will need to get a $40, 2 year SPS subscription that will only be good for your vin number, but will allow you to firmware flash any module in the car using SPS for 2 years.
Short version, will run the SPS program with the tool connected to the car/computer, will pull up your vin, give you a list of modules, pick BCM, normal programing. This will pull the needed firmware file from GM, it will pull the mileage from the dash gauge cluster, and flash in the firmware to the BCM, as well as security code hand shake the BCM to the rest of the modules as well.
If you list your location, enough of us with MDI's/Tech tools that someone close to you may have one, and all you would need to do is get the $40 subscription from A/C Delco to start with, and would be able to use that account to flash the firmware for you. The account will stay active for 2 years, and if you get a tech II/Mid down the road, will already have a account to use. If you want to one time shot to do it, the someone could add your vin to their account isntead.
Hence the account is set up on a credit card, and every time you add a vin to it, GM pulls another $40 from your credit card. So it best to have your own account, and someone can use that account on your car isntead.
FYI, I'm in Denver, so if your local to me, not a problem coming over to get you squared away.
i didn’t want to start a new thread but will if needed. I followed this and on the tech line screen for BCM under programming and replace and programming it only shows one thing “disable column lock”. I’m trying to reprogram a used BCM using the VX Nano via pass thru and I have no real options. Any chance you could lend a hand? Would be greatly appreciated. I can send you a PM if better suited. I been fiddling with this for 3 hours.
The disable column lock firmware file that is the only file that shows up under tds for 2005, should do a full flash to the BCM, so long as you selected replace and flash ecm to start with to security key the replacement BCM wit the rest of the car as well.
In 2006 and later C6, your still only going to find a single file in the BCM firmware for BCM in TDS, and it will be the most current file as well. If you selected just flash (as in firmware update only, and not replace and flash for a BCM replacement), then your down the wrong path to start with.
If you want to phone chat and have me talk you through it, then click on my name to send me a PM with name and phone number, and can call you talk you through the firmware flash when I'm available.
As for a full flash of a used BCM (no matter if the BCM was in a convert, and putting it in a hard top), have not had a problem with it using TIS2000, but GM may have changed up some items in TDS online that is causing those problems instead.
As for Tech2win of going into BCM set up after the SPS firmware flash, I always do that to make sure that the country of use is set correctly, then go through the RPO list to make sure what is in the car is selected correctly as well. Hence may have Hud installed that it did not come with from the factory that the Vin number will not select, or someone may have deleted the F55 in the car that I need to turn off over again after the flash.

The new BCM showed up today. Was easy to setup via Tech2. Thanks for responding much appreciated.
