The following section shows the various types of diagnostic events that you might encounter.
Vehicle use was detected while the ELD was not powered on. Ensure that the VTU (vehicle tracking unit) is firmly connected and there are no loose wires to avoid going into malfunction.
If this issue leads to the aggregated driving time being reduced by 30 minutes over a 24-hour period across all drivers using this vehicle, including unidentified drivers, a power compliance malfunction is raised.
-
The VTU has lost power during operation.
-
The VTU has become unplugged or has a loose wire.
-

Your mobile device lost connection to vehicle data. Ensure that Bluetooth is always enabled on your mobile device and that you shut down the vehicle or disconnect from it under “Setup” before taking the tablet out of range.
While this diagnostic event is raised, the data on engine power status, vehicle motion status, miles driven, and engine hours can no longer be accessed. If the connection is lost for 30 minutes or more during a 24-hour period, an engine sync compliance malfunction is raised.
