Yes I see that, however my experience is that many customers don't even like waiting a few hours so I wanted to be sure you still wanted to know or had not found the answer otherwise.
So on that, here is how its done, but its not something one can do on your own.
In the shop were use these steps. The programming is done with the GM MDI which is our newer scan tool that interfaces with the GM server through a computer to program. I wish I could tell you way to do this on your own without, but its just not possible. .

Body Control Module Programming and Setup


A new body control module (BCM) must be programmed with the latest operating software and vehicle calibrations. Ensure that the following conditions exist in order to prepare for BCM programming:

  • The battery is fully charged.
  • The ignition switch is in the ON position.
  • The data link connector (DLC) is accessible.
  • All disconnected modules and devices are connected.

Note: The vehicle will not start and many other functions may not operate properly if a replacement BCM is not properly set up. The following procedures must be followed:

  1. Programming the BCM
  2. Learning the restraints ID

Note: After the procedure is completed, the personalization settings of the BCM are set to default settings. Inform the customer that the personalization must be set again.

Navigate on the scan tool to Vehicle Control Systems > Module Setup > Body Control Module > Setup SDM Primary Key in BCM, then follow the instructions on the screen.

Note: After programming, perform the following to avoid future misdiagnosis:

  1. Turn the ignition OFF for 10 seconds.
  2. Connect the scan tool to the data link connector.
  3. Turn the ignition ON, with the engine OFF.
  4. Use the scan tool in order to retrieve history DTCs from all modules.
  5. Clear all history DTCs.
