ELD data diagnostics / Malfunction management
TruxTrax provides the ELD Data Diagnostics/Malfunction Management sheet and User Manual for drivers which is
available for download from the support centre at www.truxtrax.com/support. TruxTrax recommends that each driver
has a printed version of the ELD Data Diagnostics/Malfunction Management sheet and User Manual which they can
present to an inspection officer during a roadside inspection and for trouble shooting case of an ELD malfunction or
any assistance that is needed.
A motor carrier must ensure that its drivers possess onboard a commercial motor vehicle an ELD information packet
containing the user manual for the driver describing how to operate the ELD; An instruction sheet for the driver
describing ELD malfunction reporting requirements and recordkeeping procedures during ELD malfunctions; and a
supply of blank drivers records of duty status graph-grids sufficient to record the drivers duty status and other related
information for a minimum of 8 days.

Data Diagnostics
An ELD must have the capability to monitor its compliance with the technical requirements. It must detect and record
events related to malfunctions and data inconsistencies. (Subpart B, section 4.6)
Data Diagnostic Events: These events are when an ELD indicates there is a data inconsistency. The driver must follow
the recommendations by the ELD provider to resolve the inconsistency, if it occurs. [Section 49 CFR 395.34(c)]
Power data diagnostic code 1
An ELD must monitor the Data it receives from the engine ECM or alternative sources, and data record history to
identify instances when it may not have complied with the power requirements
Cause

ELD not fully functional within one minute of the engine turning on
Wiring or power source fault

Response
Drivers must check that their logs are correct by reviewing them on the mobile application. Then, they can resolve the
diagnostic event by turning of the Truck engine and restarting. The driver must notify the carrier and TruxTrax by
following the hard malfunction process if these events become a regular occurrence.
Engine synchronization diagnostic code 2
An ELD is required to establish a link to the engine ECM, and must record an engine synchronization data diagnostics
event, when it no longer can acquire values for the ELD parameters required for records within five seconds.
Cause

Wiring or connection fault

Response
Drivers must notify the carrier as soon as possible and arrange for the ECM link to be restored. Once the ECM link is
restored, drivers must thoroughly review their logs and edit, as necessary, to ensure they are correct.
Then, they can resolve the diagnostic event by turning of the Truck engine and restarting. The driver must notify the
carrier and TruxTrax by following the hard malfunction process if these events become a regular occurrence.

Missing required data elements data diagnostic code 3
An ELD must monitor the completeness of the ELD event record information in relation to the required data elements
for each event type, and must record a missing data element and data diagnostics event for the driver, if any required
field is missing at the time of recording.
Cause

Temporary or permanent loss of GPS
Intermittent or disconnected link to the vehicle ECM

Response
Drivers can resolve this data diagnostic by manually entering the missing data associated with their records along with
an explanation. The driver must notify the carrier and TruxTrax by following the hard malfunction process if these
events become a regular occurrence.
Data transfer data diagnostic code 4
An ELD must implement in-service monitoring functions to verify that the data transfer mechanism(s) are continuing to
function properly. An ELD must verify this functionality at least once every seven days.
Cause

ELD fails to communicate records to TruxTrax for seven continuous days

Response
Unless driving in an area with known cellular coverage issues, drivers should notify their carrier immediately. This fault
auto-resolves, if the device begins to communicate successfully again. The driver must notify the carrier and TruxTrax
by following the hard malfunction process if these events become a regular occurrence.
Unidentified driving records data diagnostic code 5
If more than 30 minutes of driving in a 24-hour period shows unidentified driver on the ELD, the ELD must detect and
record an unidentified driving record data diagnostic event, and the data diagnostic indicator must be turned on for all
drivers logged in to that ELD for the current 24-hour period and the following seven days.
Cause

More than 30 minutes combined vehicle use without a logged-in driver

Response
Drivers must review the unidentified journeys recorded on the ELD and accept any periods of drive time recorded,
while they were driving and not logged in to the ELD system.

Malfunctions management
Malfunction events are when the ELD detects technical compliance issues. The driver must: (1) notify the motor carrier
within 24 hours, (2) reconstruct the record of duty status for the current 24 hours and the last seven days on graph grid paper logs that comply with Section 49 CFR 395.8. Keep paper logs until the ELD is serviced and brought back
into compliance. [Section 395.34(a)]
Power compliance code P
An ELD must monitor the data it receives from the engine ECM or alternative sources, and data record history to
identify instances when it might not have complied with the power requirements.
Cause

More than 30 minutes of driving time lost in a 24-hour period

Response
Drivers should review and correct their logs, and notify their carrier of the fault. Once the fault has been corrected, the
malfunction is cleared by explaining the fault and resolution in the ELogbook notes section.

Engine synchronization code E
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.
Cause

More than 30 minutes without ECM engine synchronization over a 24-hour period

Response
Drivers must notify their carrier as soon as possible and arrange for the ECM link to be restored. Once the ECM link is
restored, drivers must thoroughly review their logs and edit, as necessary, to ensure they are correct. Then, they can
resolve the diagnostic event by turning of the Truck engine and restarting. The driver must notify the carrier and
TruxTrax by following the hard malfunction process if these events become a regular occurrence.
Timing compliance code T
The ELD must periodically cross-check its time with an external UTC source, and must record a timing compliance
malfunction when it can no longer meet the underlying timing requirement of less than 10 minutes time deviation.
Cause

Vehicle has been out of service for sufficient time that the internal clock is no longer accurate, and the ELD
has not yet synchronised its time

Response
Once the internal clock has been corrected, drivers are prompted to review their logs before resolving the malfunction.
Then, they can resolve the diagnostic event by turning of the Truck engine and restarting. The driver must notify the
carrier and TruxTrax by following the hard malfunction process if these events become a regular occurrence.
Positioning compliance code L
An ELD must monitor elapsed time during periods when the ELD fails to acquire a valid position measurement within
five miles of the CMVs 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.
Cause

More than 60 minutes without a valid GPS fix in a 24-hour period

This malfunction might appear during a temporary loss of a valid GPS fix, but it auto-resolves once GPS is restored.
The driver must notify the carrier and TruxTrax by following the hard malfunction process if these events become a
regular occurrence.
Data recording compliance R
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 cataloged remotely by
the motor carrier.
Cause

Hardware fault

Response
The driver must notify the carrier and TruxTrax by following the hard malfunction process.
Data Transfer compliance code S
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.
Cause
Failure to communicate for three days following a data transfer data diagnostic event

Response
Unless driving in an area with known cellular coverage issues, the driver must notify the carrier and TruxTrax by
following the hard malfunction process if these events become a regular occurrence. This fault auto-resolves, when
the device begins to communicate successfully.

ELD hard malfunction process
If the TruxTrax ELD (TruxBox) is experiencing a hard malfunction whereby the driver is unable to resolve an event or
the events are recurring repeatedly the driver/carrier should:

Contact TruxTrax support at [email protected]
Take note of the malfunction and provide a written description to your fleet manage within 24 hours
Keep a paper log or use the TruxTrax mobile app ELogbook feature for that day and until the ELD is repaired
or replaced. In the event of an inspection, you may display the previous 7-14 days from the mobile app.

Important information concerning malfunctions
If a motor carrier receives or discovers information concerning the malfunction of an ELD, the motor carrier must take
actions to correct the malfunction of the ELD within 8 days of discovery of the condition or drivers notification to the
motor carrier, whichever occurs first.
In the event of an ELD malfunction, TruxTrax will send a new ELD device upon notification from the owner-operator or
fleet manager.
If a motor carrier requires a time extension, they must notify the FMCSA Division Administrator for the State of the
motor carriers principal place of business within 5 days after a driver notifies the motor carrier. (Section 395.34(2))
