NOTE:
It is important to have the vehicle in an open outside area where a cellular call can be successfully placed and GPS data can be received from the satellites. It is also necessary to inform the OnStar® Call Center advisor that this call is for vehicle diagnostic purposes.
- Ignition ON, observe the GPS signal status indicator for at least 10 seconds with a scan tool. The indicator should display Yes.
- If the indicator does not display Yes, refer to Circuit/System Testing .
- Call and verify the OnStar advisor has received the GPS data.
- If the advisor did not receive the GPS data and the call was a 'fail to voice', contact the GM Technical Assistance Center.
- If the advisor did not receive the GPS data and the call was not a 'fail to voice', refer to Circuit/System Testing .
- Verify with the OnStar Call Center advisor that your actual position is within a reasonable distance from the actual location of the vehicle.
- If your actual position is not within a reasonable distance from the actual location of the vehicle, replace the K73 telematics communication interface control module.
