I should add that, in DPS it doesn't work the same...  but before you program, do a Get Controller Info, make sure your VIN shows and hit ok.  When you do the read, the ECU ID is 40.   But basically, I took your VIN calibrations and just dropped the powertrain control in.  If you get something that acts different, we can do a process of elimination and see if we can find the exact flags that control just the heated seats.  There's not too many changes thankfully on this one.  It may have had another feature that you don't have though (TPMS for example).  

Thanks! One question: My vehicle VIN (where heated seats are being transplanted into) is 0M4109519, and filename has the other VIN, are you sure you got that right?

I'll just tell you how I do it ;).

1G1FY6S03M4105237-2021-Chevy-Bolt-BCM-HS.zip1G1FY6S03M4105237-2021-Chevy-Bolt-BCM-Factory.zip Do NOT rename (especially multiple downloads, browsers like to add (1) ) or unextract the files (unless you want to look at them).    Key on, Engine off.  Go into DPS Programming, pins 6 & 14, Select cal (pick the zip file you want - Factory or Heated Seats), then Program.  You might get an error, actually I expect you will (due to not entering an unlock code) but it should be at the end of the script.  Feel free to attach the log file here if so but unless you have a comms error or similar, it should make it close to the end.   This one does come with a warning as well, see attached.  

@codebuilder I have no issue with order of files. Issue is with build. There no enough information how to and should be included in tool. I know I can buy additional Tutorial, but atm cannot afford 5$, not to mention 100-150$ for How to build Type4 Tutorial. And will end where still have not full/complete information

Yeeaaahhh,  Type 4 can be a PITA.  The ordering gets messy...  And you can't really auto detect it....

There's a few differences but we'll give it a try:

@codebuilder I will appreciate this, but I faced issues when build Type4 with DPS creator tool. I’m not bother to waste @Troy time and ask him to ask developer what happen. So preffer to execute Setup via SPS and that is only if part numbers match. If not match will be bit more work 

*Might* be an easy one, I'll throw you a package together and we'll find out.

I don't mind pulling the files if they get us the VIN.  If you want to do the other part, it saves me 🙂
