Removal (Vehicle Communication Unit)

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Vehicle Communication Unit (VCU) has a specific set of unique numbers that tie a module to each vehicle. 10-digit station identification and 11-digit electronic serial number are used by National Cellular Network and OnStar® to identify a specific vehicle. Because these numbers are tied to a vehicle identification number of a vehicle, these parts must never be exchanged with those of another vehicle.
