Important Notice
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.
Important: You must never exchange these parts with those of another vehicle.
Removal and Installation Procedure
Follow the procedure to replace the VCIM, including recording the 10-digit STID number and the 11-digit ESN number from the labels on the new module.
Ensure proper installation and reconfiguration of the OnStar@ system to avoid additional customer visits for repair.
