Global Positioning System Module: Service and Repair
COMMUNICATION INTERFACE MODULE REPLACEMENTREMOVAL PROCEDURE
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.
1. Disable the SIR.
2. Remove the passenger inflatable restraint module.
3. Remove the I/P carrier bolts on the passenger side.
4. Remove the bolt (1) for the module bracket strap (7).
5. Remove the module bracket strap (7) from the mounting bracket (3).
6. Slide the module (2) upward in the mounting bracket.
IMPORTANT: The generation 5 module uses four connector cavities. In addition, the STID and the ESN information on the generation 5 label can not be used to update the customer account information if the module is replaced. Use a scan tool to access this information.
7. Disconnect all the electrical connector (3) from the communication interface module (1).
8. Disconnect all the coaxial cable connectors (4) from the module (1).
9. Pull downward on the back of the I/P compartment to remove the OnStar(R) module (2) from the bracket (3).
10. Remove the module (2) through the opening for the passenger inflator module.
INSTALLATION PROCEDURE
1. Install the OnStar(R) module (2) thorough the opening for the passenger inflator module.
2. Pull downward on the back of the I/P compartment to install the module to the bracket (3).
3. Slide the unit upward in the mounting bracket.
4. Connect the electrical connectors (3) to the module (1).
5. Connect the coaxial cable connectors (4) to the module (1).
6. Reposition the module (2) in the bracket.
7. Install the module bracket strap (7) to the mounting bracket (3).
8. Install the bolt (1) for the module bracket strap (7).
NOTE: Refer to Fastener Notice in Service Precautions.
Tighten
Tighten the bolt to 4 N.m (35 lb in).
9. Install the I/P bolts on the passenger side.
Tighten
Tighten the bolt to 2.3 N.m (20 lb in).
10. Install the passenger inflatable restraint module.
11. Enable the SIR.
12. Install the scan tool. Use the special functions menu in order to perform the OnStar(R) setup procedure for this vehicle.
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.
13. 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.
14. 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.
15. Press the blue OnStar(R) button to connect to the OnStar(R) Call Center and perform the following procedure:
15.1. Tell the advisor that this vehicle has received a new VCIM.
15.2. Ask the advisor to add the new STID and the ESN to update the customer's account.
15.3. Follow any additional instructions from the OnStar(R) advisor.
15.4. Ask the advisor to activate the OnStar(R) Personal Calling feature, if available.
16. The default language for voice recognition in the generation 5 OnStar(R) module is English.
