The Body Control Module is not programmable except for alarm and keyless entry options. The procedure for that is in your owner's manual and posted in this forum several times. Other than that, the only programmable item is the matching of the ignition key for VATS. This is done automatically the first time the key is used with a new BCM - once it's done it can never be changed.
In fact, although the BCM stores DTCs (Diagnostic Trouble Codes), you don't access them with any kind of special tool. You access the DTC history using a procedure similar to programming the alarm using the ignition switch and a combination of other dash switches. It flashes the SECURITY light in the instrument cluster to display the DTCs much like the light on an answering machine shows the number of messages.
