Removal Procedure

Important:  The vehicle communication interface module (VCIM) 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.

1. Remove the windshield garnish molding. Refer to GARNISH MOLDING REPLACEMENT - WINDSHIELD PILLAR  in Interior Trim.
2. Remove the upper trim pad. Refer to TRIM PLATE REPLACEMENT - INSTRUMENT PANEL (I/P) ACCESSORY  in Instrument Panel, Gages and Console.
