Removal Procedure

WARNING: This page is about a different car, the 2002 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Do not exchange the vehicle communication interface module with other vehicles. Each vehicle communication interface module has a Specific Station Identification (STID) and Electronic Serial Number (ESN). These identification numbers are stored in the General Motors vehicle history files by VIN and are used by OnStar® and the National Cellular Telephone Network.
