When does an electronic logging device (ELD) “missing required data elements data diagnostic event” occur?
A “missing required data elements data diagnostic event” occurs when any required data field is missing at the time of its recording.
When does an electronic logging device (ELD) “data recording compliance malfunction” occur?
A “data recording compliance malfunction” occurs when an ELD can no longer record or retain required events or retrieve recorded logs that are not kept remotely by the motor carrier.
When does an electronic logging device (ELD) “positioning compliance malfunction” occur?
When an ELD fails to acquire a valid position measurement within 5 miles of the commercial motor vehicle moving and 60 minutes has passed, a “position compliance malfunction” will be recorded in the data diagnostic.
When does an electronic logging device (ELD) “timing compliance malfunction” occur?
A “timing compliance malfunction” occurs when the ELD can no longer meet the underlying compliance requirement to record Coordinated Universal Time (UTC), where ELD time must be synchronized with UTC, not to exceed an absolute deviation of 10 minutes at any time.
When do electronic logging device (ELD) “engine synchronization data diagnostic events” and “engine synchronization compliance malfunctions” occur?
“Engine synchronization data diagnostic events” occur when an ELD loses ECM connectivity to any of the required data sources (engine power status, vehicle motion status, miles driven, and engine hours) and can no longer acquire updated values for the required ELD parameters within five seconds of the need. “Engine...
When do electronic logging device (ELD) “power data diagnostic events” and “power compliance malfunctions” occur?
“Power data diagnostic events” occur when an ELD is not powered and fully functional within one minute of the vehicle’s engine receiving power and does not remain powered for as long as the vehicle’s engine stays powered. “Power compliance malfunctions” occur when an ELD is not powered for an...
Is an ELD required to monitor its compliance with the ELD technical requirements?
Yes. An ELD must monitor its compliance with the ELD technical requirements and detect malfunctions and data inconsistencies related to power, data synchronization, missing data, timing, positioning, data recording, data transfer, and unidentified driver records requirements. The ELD output will identify these data diagnostic and malfunction events and their...
Would an electronic logging device (ELD) be non-compliant with the ELD rule if the data cannot be sent electronically to an authorized safety official at roadside?
No. If the electronic means for transferring data is unavailable or fails, the driver can still be compliant by showing either a printout or the actual ELD display of their RODS.
What is the process for transferring data via Web services?
If the driver is using a “telematics” ELD with wireless Web services capabilities, the authorized safety official will give the driver a routing code to assist the official in locating the data once transmitted, and the driver will initiate a web transfer to an FMCSA server to be retrieved...
What is the process for transferring data via Bluetooth?
If the driver is using a “local” ELD with Bluetooth capabilities, the authorized safety official will activate Bluetooth on his or her computing device and the driver will initiate the Bluetooth electronic transfer of the data from the driver’s ELD to the safety official’s computing device. The official will...
