Circuit/System Verification

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

This procedure is not used in Brazil.

NOTE:
  • It is necessary to have the vehicle in an open outside area where a cellular call can be successfully placed and GPS data can be received from satellites.
  • The vehicle should be located in a quiet area.
  1. Ignition ON, press OnStar® Call button. Verify that your voice is heard clearly by the OnStar® Call Center.
  2. Press the OnStar® Call answer button. Attempt to operate the OnStar® system using multiple different voice commands. Verify the system responds appropriately to all voice commands.
    • If the OnStar® system does not respond to any voice commands, replace the CIM.
  3. If the system is operational, but does not respond appropriately to certain commands refer to OnStar Description and Operation  for tips on proper pronunciation.
