Communication Interface Module Replacement
Removal Procedure
Important: The communication interface module has a specific set of unique numbers that tie the module to each vehicle. These numbers, the
10-digit station identification and the 11-digit electronic serial number, are used by the National Cellular Network and OnStar to identify the
specific vehicle. Because these numbers are tied to the vehicle identification number of the vehicle, you must never exchange these parts with
those of another vehicle.
