ELD Malfunctions

AIKS-ELD-blogELD devices has a mechanism of self-monitoring its compliance with ELD technical requirements. The devices monitor its compliance on regular basis and detect malfunctions related to power, data synchronization, missing data, timing, positioning, data recording and data transfer. Record of each malfunction is maintained with its “malfunction cleared” event in the logs of all driver.

1. “Power Compliance” malfunctions.

“Power compliance malfunctions” occur when an ELD is not powered with vehicles motion of total 30 minutes or more in a 24-hour period across all driver profiles including unidentified driver profile.

2. “Engine Synchronization Compliance” malfunctions.

“Engine synchronization compliance malfunctions” occur when ECM fails to provide updated values of required parameters such as engine power status, vehicle motion status, miles driven, and engine hours for more than 30 minutes during a 24-hour period combined across all driver profiles including unidentified driver profile.

3. “Data Recording Compliance” malfunction

A “data recording compliance malfunction” occurs when an ELD fails to record or maintain required events or retrieve recorded logs that are not kept remotely by the motor carrier.

4. “Data Transfer Compliance” malfunctions

A “data transfer compliance” malfunction occurs when the ELD stays in the unconfirmed data transfer mode following the next three consecutive monitoring checks.

5. “Timing Compliance” malfunction

A “timing compliance malfunction” occurs when the ELD is not able to record Coordinated Universal Time (UTC), where ELD time must be synchronized with UTC and should not exceed an absolute deviation of 10 minutes at any time.

6. “Positioning Compliance” malfunction

When an ELD fails to record a valid position measurement within 5 miles of the commercial motor vehicle movement for more than 60 minutes over a 24-hour period, a “position compliance malfunction” will be recorded in the data diagnostic.

7. “Data Transfer Compliance” malfunctions

ELD monitors its compliance with data transfer mechanism at least once in every 7 days. A “data transfer compliance” malfunction occurs when the ELD fails to confirm the working status of this mechanism. At this point ELD enters the unconfirmed data transfer mode and stays in this mode for following next three consecutive monitoring checks.

The malfunction cleared event is based on different factors depending on which type of malfunction took place.
