  8. Install the CIM fastener.

    Tighten:  Tighten the fastener to 10 N.m (89 lb in).

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

  11. 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.
  12. 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.
  13. Press the blue OnStar® button to connect to the OnStar® 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® advisor.
    4. Ask the advisor to activate the OnStar® Personal Calling feature, if available.
