Question about adding options to BCM using Tech2 and software
Question about adding options to BCM using Tech2 and software I am hoping some of the Tech2 Pro's can provide a bit of missing knowledge. I am working to finalize the installation of air conditioned seats (sourced from a 2010 LTZ Sub) in my 2008 Avalanche (LTZ with heated mem seats previously). After installation everything works except the cooling button and the memory seat function. Memory button beeps indicating memory stored but will not retrieve seat position. Troubleshooting leads me to believe I probably need to program the BCU to know that the truck now has climate controlled seats (seats came with all modules). I have borrowed a friends Tech2 clone but understand I likely need some software to program the BCU with using the T2 as a passthrough. The question is what software and where do I get it. Have W10 and W11 computers available.
Thanks in advance for any pointers in the right direction.

You will need an AC Delco TDS account. I think your cloned tech 2 will work. GM cracked down end of 2024 on the cloned MDI's and cloned hardware. GM will block your account if you use a cloned device. All the clones apparently use the same serial number so its easy foe them to block. A lot of options can just be turned off or on but some require programming. The GM programming is VIN based so if it doesnt give you an option to turn on AC seats its not going to be as easy as just re-programming the BCM.
Don't suppose there is an affordable work around for this? Don't really like the stealership business model and I don't live in a major metro area like Atlanta or Dallas or anything, would prefer to pay an indy guy who knows what he is doing but seems unlikely I would one here in central VA.
Tech 2 will no longer program in a pass thru configuration like the old day's. GM now uses the MDI 2 or MDI as a passthru and a TIS terminal programming software.
To even open the door to maybe get it all to work you'll need a passthru programming device like above.
In order for it to work the driver and passenger door heated cooled switches need to be installed and then the driver and passenger door modules and the memory seat module must be configured for KB6 cooled seats. Now for the kicker when you pull up these modules it may or may not give you the ability to program them for the KB6 option to enable them it all depends on what VIN information is loaded up based on the vehicles original configuration.
I've done it successfully and can do it and have all the access but these "new " vehicles are way to difficult to explain it as a DIY driveway project. If you were local I'd say come on by and well try.
The old day's of adding options you didn't want to pay for are pretty much long gone.

Have this problem on my restomod project and the dealerships (two that I tried) were all about legal and liability. No chance they were interested and I know the owner.

For the most part you cannot add or remove options period ecm bcm radio you name it. When you enter in the vin in tis it populates the modules that vehicle uses and the options that vehicle was equipped with are just calibration numbers there isn't a RPO chart call out to go through and manually select. There are very few modules that let you select the options manually.
The door modules are one of the few it will let you select the mirror type and the seat type is only sometimes depending on the vehicle trim level.

I thought it was possible to do this by using a different VIN from the donor truck? Might have to match the VIN with the ECM as well but not that worried about that as I could just modify the ECM program using my HPTuners
Before going crazy trying to find a way around what if scenearios the first thing I would do is just update both modules and see if it gives options of cooled seats if it does click it flash it and your money.
You also have to change out the buttons in the door handle to heated cooled assy they are not the same as heated only.

There is a "BCM Hammer" group on Facebook where some people are trying to figure out how to adapt PCM Hammer to work on BCMs. I haven't been following it, but it couldn't hurt to check with them. This would only work on vehicles from roughly the P01 / P59 PCM era, since GM used different communication buses before and after that period.
And on a related note, the "IPC Hammer" gang has made some progress with hacking the instrument panels.

Well I guess now I need to find someone who has the real deal and can do the work. If anyone know of anyone who can do it with me shipping the BCM to them or maybe in the Central VA or Northern/Wester NC area please drop the det's.

I wouldn't be surprised but I just used it a couple weeks ago to flash a new pcm for a customers malibu
