OnStar Reconfiguration

Important: The vehicle communication interface module (VCIM) has a specific set of unique numbers that tie the module to a specific vehicle. These numbers, the 10-digit station identification and 11-digit electronic serial number (ESN), are used by the National Cellular Network and OnStar(R) to identify the specific vehicle. Because these numbers are tied to the vehicle identification number of the vehicle, these parts should NOT be exchanged with those of another vehicle. After replacing the VCIM, it is essential to reconfigure the OnStar(R) system. 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(R) system. This action will cause a DTC to set.

1. Install the scan tool. Use the ID information menu on the scan tool to access and record the new station ID (STID) and the ESN from the new VCIM.
2. Move the vehicle to an open area that is away from tall buildings with a clear view of unobstructed sky. Allow the vehicle to run for 10 minutes.
3. Use the special functions menu in order to begin the VCIM setup procedure for this vehicle.
4. Following this VCIM Setup procedure, a call will automatically be made to the OnStar(R) Call Center. Inform the Call Center Advisor of the following:
* Tell the advisor that this vehicle has received a new VCIM.
* Ask the advisor to add the new STID and the ESN to update the customer account.
* Ask the advisor to activate the OnStar(R) Personal Calling feature, if available.
* Follow any additional instructions from the OnStar(R) advisor.
5. Cycle the Ignition to complete the procedure and clear the DTC B1001 once the call to the OnStar(R) Call Center advisor is complete.
6. The default language for the new VCIM is English. Refer to the Module Setup screen if the customer requests French or Spanish Voice Recognition.
