My challenge was getting my CJB/BCM to recognize the immobilizer module after my laptop froze while downloading the current car configuration file.
For anyone else that finds themselves in a similar situation, today, I went ahead and reprogrammed my existing CJB/BCM as if it were a new module using SDD.
Over the past couple weeks, I have done a ton of searches and have asked around and nobody could or would give the advice to simply go through the process of adding a new BCM module but keeping the original BCM in place during that process.
The process worked perfectly and my BCM now communicates with the Column Lock Module/Immobilizer. I didn't have to disconnect any modules.
I did unlock SDD into engineering mode but I'm not 100% certain that was necessary.
In the "extras" menu, I clicked on the link to "add new BCM" and followed all of the steps.
You do need to know the various accessory levels that your specific car has (e.g. high-line Cluster, Premium audio, etc...) to ensure it configured everything properly during this reprogramming step.
Beyond that, there were a couple of additional steps
1) The process requires reprogramming of the TPM wheel sensor IDs into the BCM so you need to be able to read those and enter them at that step
2) you also have to reprogram any/all key fobs that you have so you'll have to have those with you. Any that you don't have won't be added will not work. You can go back later to reprogram those if you need to.

After all of that, the final steps that are built into pretty much every routine are to read and clear all error codes.

As a novice user of SDD, I can say that I was rather nervous to take that step but I figured I might as well give it a try as I'd been without my car for a few weeks now.
The car now runs and drives fine again!

Now, back to the original task of swapping out the faulty fuel pump relay.

Thankfully, it's not my daily driver!
