Malfunctions & diagnostics events

Malfunction and diagnostic events happen whenever ELD detects technical compliance or data inconsistency issues.

When an event is detected, look for the event code on the list below and follow the respective steps to resolve it.

 

Malfunction Cause What to do
Power compliance (P) More than 30 minutes of driving time lost in a 24-hour period

Review and correct your logs, then notify the carrier of the fault. Once the fault has been corrected, the malfunction is cleared by explaining the fault and resolution in the Recap logs notes section.

Engine synchronization (E) More than 30 minutes without Engine Control Module (ECM)  synchronization over a 24-hour period

Notify the carrier as soon as possible and arrange for the ECM link to be restored. Once it's restored, review and correct your logs, then restart the truck engine.

Timing compliance (T) 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

Correct the internal clock, review and correct your logs, and then restart the truck engine.

Positioning compliance (L) 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.

Data recording compliance (R) Hardware can no longer record or retain required events, or retrieve recorded logs that are not otherwise cataloged remotely by the motor carrier. Notify the carrier as soon as possible.
Data Transfer compliance (S) Failure to communicate records to EROAD Depot for three days following a Data transfer data diagnostic event

Unless driving in an area with known cellular coverage issues, you should notify the carrier immediately. This fault auto-resolves if the device begins to communicate successfully again.

 

Diagnostics  Cause What to do
Power data diagnostic (1)

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

Review and correct your logs, then restart the truck engine.

Engine synchronization diagnostic (2) ECM can no longer acquire values for the ELD parameters required for records within five seconds.

Notify the carrier as soon as possible and arrange for the ECM link to be restored. Once it's restored, review and correct your logs, then restart the truck engine.

Missing required data elements data diagnostic (3)

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

Manually enter the missing data associated with your records along with an explanation.

Data transfer data diagnostic (4) Failure to communicate records to EROAD Depot for seven continuous days.

Unless driving in an area with known cellular coverage issues, you should notify the carrier immediately. This fault auto-resolves if the device begins to communicate successfully again.

Unidentified driving records data diagnostic (5) More than 30 minutes of driving in a 24-hour period without an identified driver on the ELD. You must review the unidentified recorded journeys and accept any periods of drive that you were driving and not logged in.
