| Malfunction Notes | Power Compliance Monitoring: An ELD must monitor data it receives from the engine ECM or alternative sources, its onboard sensors, and data record history to identify instances when it may not have complied with the power requirements, in which case, the ELD must record a power data diagnostics event for the corresponding driver(s), or under the unidentified driver profile if no drivers were authenticated at the time of detection. An ELD must set a power compliance malfunction if the power data diagnostics event indicates an aggregated in-motion driving time understatement of 30 minutes or more on the ELD over a 24-hour period across all driver profiles, including the unidentified driver profile. If this occurs, try power cycling the ignition. If the problem persists, contact your OEM or Samsara Support for further assistance. Engine Synchronization Compliance Monitoring: An ELD must monitor the data it receives from the engine ECM, its onboard sensors, and data record history to identify instances and durations of its non-compliance with the ELD engine synchronization requirement. An ELD must set an engine synchronization compliance malfunction if connectivity to any of the required data sources is lost for more than 30 minutes during a 24-hour period aggregated across all driver profiles, including the unidentified driver profile. If this occurs, try power cycling the ignition. If the problem persists, contact your OEM or Samsara Support for further assistance. Timing Compliance Monitoring: The ELD time must be synchronized to Coordinated Universal Time (UTC) and the absolute deviation from UTC must not exceed 10 minutes at any point in time. It must record a timing compliance malfunction when its deviation exceeds this bound. If this malfunction occurs, check the mobile device settings to ensure that it is set to update its time automatically. Positioning Compliance Monitoring: An ELD must monitor elapsed time during periods when the ELD fails to acquire a valid position measurement within 5 miles of the CMV’s movement. When such elapsed time exceeds a cumulative 60 minutes over a 24 hour period, the ELD must set and record a positioning compliance malfunction. This may be caused by a temporary loss in GPS signal. If this occurs, try power cycling the ignition. If the problem persists, contact your OEM or Samsara Support for further assistance. Data Recording Compliance Monitoring: An ELD must monitor its storage capacity and integrity and must detect a data recording compliance malfunction if it can no longer record or retain required events or retrieve recorded logs that are not otherwise catalogued remotely by the motor carrier. Contact your OEM or Samsara Support for assistance in resolving this issue. Data Transfer Compliance Monitoring An ELD must implement in-service monitoring functions to verify that its data transfer mechanisms are continuing to function properly. If the monitoring mechanism fails to confirm proper in-service operation of the data transfer mechanisms, an ELD must record a data transfer data diagnostic event and enter an unconfirmed data transfer mode. After an ELD records a data transfer data diagnostic event, the ELD must increase the frequency of the monitoring function to check at least once every 24-hour period. If the ELD stays in the unconfirmed data transfer mode following the next three consecutive monitoring checks, the ELD must detect a data transfer compliance malfunction. Check your internet coverage if this problem persists as a network connection is required for the transfer to complete. |
