MISSING DATA FROM ECM: IF ECM CONNECTION STATUS INDICATOR TURNS RED WHILE THE BLUETOOTH INDICATOR IS GREEN OR IF A MISSING REQUIRED INFORMATION DATA DIAGNOSTIC EVENT IS TRIGGERED, FOLLOW THESE STEPS TO TROUBLESHOOT.
A. Make sure that the ECM Device is fully connected to the diagnostic port and the vehicle is powered ON. Once the vehicle is powered on the ECM Device should have the power it needs to transmit data from the engine to the driver application
B. If the application is not yet connected to the ECM device, attempt connection by tapping Main Menu and Scan Devices to discover and connect to the correct ECM device
C. Tap the Main Menu icon and select Diagnostic. This will run a diagnostic test on the ECM device to determine which of the required ELD data elements are missing (odometer, RPM, speed, etc.).
You can also ask the driver if they have a red diagnostic (“D”) or Malfunction (“M”) icon in the top right corner of their application home screen. If so see section III for a guide on what different diagnostic codes and malfunctions refer to/ troubleshooting steps for them (*Note that not all listed diagnostics and malfunctions relate to connection/ diagnostic issues*).
D. If the resolutions in section III do not resolve the issue, attempt an Unplug/Plug in of the ECM device
1. Manually disconnect ECM device from vehicle on the application by scanning for a device and then not making a new device selection
2. Logout from app
3. Unplug ECM device from diagnostic port of vehicle
4. Wait 30 seconds, then plug ECM device back into diagnostic port
5. Login to app
6. Manually connect vehicle to ECM device on the application once more and check the diagnostic screen
7. If this still does not resolve the issue proceed to section II-E
D. LEGAL references for more information: eCFR :: Appendix A to Subpart B of Part 395, Title 49 -- Functional Specifications for All Electronic Logging Devices (ELDs), Section 4.2:
1. Manually disconnect vehicle to ECM device on the application by scanning for a device and then not making a new device selection
2. Logout from app
3. Power cycle mobile device by completely shutting down and restarting the device
4. Login to app
5. Manually connect the vehicle to ECM device on the application once more
