Summary
This Preliminary information communicates an issue where the aux switch "on" LED indicators do not illuminate within the aux switch if more than one aux switch is turned on.  The aux switches do work regardless of how many are turned on, but the "on" LED indicator will only be illuminated in which ever aux switch is first pressed. Dealers are to reprogram the BCM to correct this concern.
