Question:
How do I interpret the icons found in the Log Overview page?
Answer:
Answer: Using the above example -
In this case and for today for this driver, you will find Engine sync malfunction. After finding this message you should look for is an Engine sync diagnostic cleared. The cleared message will let you know the issue is no longer present on the truck and if the issue does not return, the message icon on the truck will be removed in 24 hours.
If you do not see Engine sync diagnostic cleared, you will then click on one of the buttons that Requests Current Logs from the truck. This will send up the Cleared message if the Malfunction has cleared. In this situation, you can see that this truck has had an issue for several days now and will most likely need to get into the shop.

4.6.1.2. Engine Synchronization Compliance Monitoring
(a) An ELD must monitor the data it receives from the engine ECM or alternative sources as allowed in sections 4.3.1.1–4.3.1.4 of this appendix, its onboard sensors, and data record history to identify instances and durations of its non-compliance with the ELD engine synchronization requirement specified in section 4.2.
(b) An ELD required to establish a link to the engine ECM as described in section 4.2 must monitor its connectivity to the engine ECM and its ability to retrieve the vehicle parameters described under section 4.3.1 of this appendix and must record an engine-synchronization data diagnostics event when it no longer can acquire updated values for the ELD parameters required for records within 5 seconds of the need.
(c) An ELD must set an engine synchronization compliance malfunction if connectivity to any of the required data sources specified in section 4.3.1 of this appendix (pg 444) is lost for more than 30 minutes during a 24-hour period aggregated across all driver profiles, including the unidentified driver profile.
