For 1990-2009 cars

## OnStar Reconfiguration without TIS2web Gen 3 and prior

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® 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® 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® 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® 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® Personal Calling feature, if available.

• | Follow any additional instructions from the OnStar® advisor.

5. Cycle the Ignition to complete the procedure and clear the DTC B1001 once the call to the OnStar® 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.

## OnStar Reconfiguration with TIS 2 Web Gen 4 and later

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 (STID) and 11-digit electronic serial number (ESN), are used by OnStar® and the cellular network to identify the specific vehicle. Because these numbers are exclusive 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® system. Failure to reconfigure the system will result in an additional customer visit for repair. DO NOT press and hold the white dot button on the keypad as it will not reset this version of the OnStar® system and may result in a DTC to be set, a red LED and limited or incomplete OnStar® services. Use of the TIS 2 Web SPS application and the Tech 2 are required in order to perform the VCIM configuration and setup procedure for this vehicle. The configuration and set-up procedure is now a two step process which enables an automated activation by the OnStar Center, without a button press by the technician to the center.

• | It may take up to 24 hours for the OnStar® service to become fully activated after performing the TIS 2 Web and Tech 2 setup procedures. Perform the OnStar® Activation procedure only once. Repeat attempts at performing the procedure may result in a delay of the activation process.

• | The Tech 2 setup procedure must begin immediately upon completion of programming. Any delay between the procedures may result in incomplete setup or activation of the VCIM.

1. Connect the Tech 2 to the vehicle.
2. Connect the Techline Information System (TIS) terminal to the Tech 2.
3. Select the OnStar® Activation programming option using the service programming system (SPS).
4. Upon completion of the OnStar® Activation programming event, disconnect the TIS terminal from the Tech 2 and perform the VCIM/OnStar Set-up Procedure using the Tech 2.
5. The default language for the new VCIM is English. Changing the language capability to French or Spanish is supported by service programming system (SPS) and by Tech 2 special functions. Changing the language capability is also dependant on the generation of the replacement OnStar module.

Inform the customer that it may take up to 24 hours for the OnStar® service to become fully activated after performing the TIS 2 Web and Tech 2 setup procedures.
