Hello @CD-1597 ,
Thank you for asking your question in our community. This error is saying the device is not communicating so we will want to verify that is the case and get this device back up and running. I would check the device for this vehicle and see if it is installed well (preferably with a zip tie). If the install seems good I would double check that you are seeing it move on the map.
Let me know if you have any other questions or need any help troubleshooting the device. I am happy to help.
Have a great day!
