1	Communication Interface Module Bolt CAUTION: Refer to Fastener Caution . Tighten: 10 N.m (89 lb in)
2	Communication Interface Module Procedure Pull down to release the module from the bracket. Disconnect the electrical connectors, the GPS antenna, and the cellular coax cable. If replacing the module, record the 10-digit STID number, and the 11-digit ESN number from the labels on the new module. Reconfigure the OnStar® system. Refer to Control Module References . When replacing the communication interface module be sure to transfer the Bluetooth antenna, if equipped. Tip: 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.
