Communication Interface Module Replacement

COMMUNICATION INTERFACE MODULE REPLACEMENT

REMOVAL PROCEDURE
1. Position the right rear seat bottom to a cargo position.

IMPORTANT: 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(R) 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.




2. Remove the protective cover from the vehicle communication interface module (VCIM).




3. Remove the module from the upper bracket by releasing the retaining tab.




4. Remove the electrical connectors from the VCIM.
5. Remove the VCIM from the vehicle

INSTALLATION PROCEDURE
1. If replacing the VCIM, record the 10-digit STID number, and the 11-digit ESN number from the labels on the new module.




2. Install the module to the upper bracket ensuring the retaining tab is fully seated.
3. Connect the 2 electrical connectors.

Tighten the module thumb screw to a maximum of 0.2 N.m (2 lb in).

NOTE: In order to avoid damage to the circuit board, do NOT over-tighten the thumb screws. Using your fingers, apply only a light pressure.




4. Install the protective cover to the module.
5. Position the right rear seat bottom to a passenger position.
6. Install the scan tool. Use the special functions menu in order to perform the OnStar(R) setup procedure for this vehicle. Programming and Relearning

IMPORTANT: After replacing the vehicle communication interface module, you must 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.

7. Move the vehicle to an open area that is away from tall buildings and with a clear view of unobstructed sky. Allow the vehicle to run for 10 minutes.
8. Use the ID information menu on the scan tool to access the new station ID (STID) and the electronic serial number (ESN) from the new VCIM.
9. Press the blue OnStar(R) button to connect to the OnStar(R) Call Center and perform the following procedure:
1. Tell the advisor that this vehicle has received a new VCIM.
2. Ask the advisor to add the new STID and the ESN to update the customer's account.
3. Follow any additional instructions from the OnStar(R) advisor.
4. Ask the advisor to activate the OnStar(R) Personal Calling feature, if available.
