Answer
These errors are created when there is a device power loss event.
Telematics device fault: telematics device has been unplugged is when the device lost power.
Telematics device fault: all power removed - device restarted is when the device gained power back and restarted.
Telematics device fault: telematics device has been unplugged and Telematics device fault: all power removed - device restarted are coupled together as the device can only report Telematics device fault: telematics device has been unplugged and the Telematics device fault: all power removed - device restarted fault after it gains power back.
Additional Notes
- A high number of these faults may indicate the vehicle is equipped with a kill switch or has an improper installation.
