Scheme 17: Communication Interface Module Battery Replacement
| Callout | Component Name |
|---|
| Preliminary Procedure Disconnect the negative battery cable. Refer to BATTERY NEGATIVE CABLE DISCONNECTION AND CONNECTION . Remove the Instrument Panel Upper Trim Panel. Refer to INSTRUMENT PANEL UPPER TRIM PANEL REPLACEMENT |
| 1 | Communication Interface Module Battery Assembly Procedure Unsnap the communication interface module battery from the bracket. Disconnect the electrical connectors. NOTE: 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. Replacement of the back-up battery (BUB) does not require reconfiguration of the VCIM. If a trouble code is indicated before the battery is replaced, the DTC must be cleared following the installation of the new battery. The OnStar® system does not need to be reconfigured unless the VCIM is replaced. When the VCIM is replaced, the OnStar® system must be reconfigured. Failure to reconfigure the system will result in an additional customer visit for repair. In addition, pressing and holding the white dot button on the keypad will NOT reset this version of the OnStar® system. This action will cause a DTC to set. |
