Are you getting a OnStar ONS-116 Error?

How long doe it take to fix an OnStar ONS-116 Error?
The time to fix an ONS-116 error ranges from 2 to 15 minutes. This is dependent on what is causing the ONS-116 error and which of the steps that will need to be completed to resolve it.
Steps to resolve a ONS-116 error:
Using the Onboard Diagnostics feature of your OnStar system, check the status of your vehicle. In some cases it will provide a quick remedy for the ONS-116 error. If you do not have a screen, and only the Blue OnStar button, you can press the button and ask the OnStar Dealer Advisor to run a Diagnostics for you.
If the first step has not resolved the ONS-116 error, you will need to move the vehicle outside if it is not already. It will need to be started and allowed to run for at least five minutes. For safety and security reasons, please do not leave the vehicle unattended. Ensure it is in a safe spot to operate at idle and that the vehicle is secure. Also ensure that the vehicle is not obstructed overhead.
After the vehicle has run for at least 5 minutes, Press the blue Onstar button.
After pressing the blue OnStar button, you will be connected with the OnStar Dealer Center. They will assist you with the process. Simply ask them for “Activation”
The OnStar Dealer Center Advisor will process your request and will send a signal to the vehicle. This may take a moment or two. Once the signal is received by the vehicle it will display an option to “Synchronize with OnStar” . Once that option is available, select it to resolve the ONS-116 error.
