Good Evening, I was watching this thread as I am having the same exact issue with the driver's memory control module. I updated every other module except this one. It fails every time. I just installed a new module today and it does the same thing. Confirmed good power and ground. Has anyone figured this out yet?
Thanks.
Thanks.

Thanks for pointing me in that direction. What was the conclusion? Are we not able to reprogram that module at home with sps? Is it just a simple reprogram procedure on the dealer end? Please elaborate as I feel like I'm giving up taking it to the dealer.

They want to make money off you. Your lucky you haven't needed a security code so far. Some modules requires them or a VIC number which they won't help you with it either. I'm having the same issue with the passenger seat module and rear axle module that it won't program. I can't swap the mileage from the bcm to the new cluster without a VIC number, I unable to reprogram a new ebcm without a security code.

I still have not been able to program either of my seat modules. I plan on attempting it again here in the next couple of weeks and I will post an update. It's finally getting nice enough that I will be able to get it out of storage for the summer. I like Laserdude's idea, might have to try that.
Was the Dealer able to program it? What did they charge you? Thanks

Finally was successfully able to program both passenger and driver seat memory modules. 
Not sure if it was a factor but I had the seat side connectors, the connector that goes the the seat motors, disconnected and had the car in the accessory position.

I had both seats unbolted so that I could get at and disconnect everything except for the MCM itself. I cleared the codes, removed both fuses for the MCM, disconnected the battery for over 10 mins and then put everything back together and tried using SPS to "Replace and Program". Still getting the failure with the exact same codes that were showing on yours.
HELP!

Hi there. Could you provide more details on how you managed to get this done? I'm having the exact same issue with the same GM P/N on a 2014 Cadillac CTS VSport Premium. It's driving me nuts!

Hopefully you can get it to work.

I wish I had more details as to why it worked but I have no clue why it did. Really the only thing I did different was unplug everything from the module except the connector that provides power and CAN signal, I think my CAN signal was on separate connector so I had 2 connectors plugged into the module. I also only put in ACC mode, just 1 press on start button (did not hold to put in RUN mode).
Hopefully you can get it to work.

After I get this figured out, it's the Android Auto/Apply Car Play upgrade install... I'm a glutton for punishment.

Thanks so much for your quick reply. I really appreciate it. I've downloaded the specs for each connector and think I know which two I need to keep plugged in. I'll give it a try today and report back. I hope this does it! I'm just annoyed that I have to take out the seat AGAIN. This is going to be the 3rd time in as many days. I can get this thing in and out about as fast as a NASCAR pit stop at this point. HAHAHA

I'm not sure what I was doing wrong with the GDS2 I've got but they solved it quickly... at a cost of $180 CDN for a "1 hour diagnostic" arguing that even though I was telling them what the problem was, they had to inspect it themselves.

Gotcha. Thanks for the reply. I just dropped off the car my to the dealer and I am sure I am in for a similar treat at $140 though for 1 hour 
*Update* So the dealer did as TorontoCTSV had done and they had no issues re-programming the power seat module. The technician came out and asked if I was using a VCX Nano, for which I said I was, and he said this isn't the first instance of seeing this happen. So in my mind, there is some minor limitation to these knock-off/clone devices. Anyways, issue resolved.
