Troubleshoot missing automatic duty status changes (ADSC)

Restore automatic drive and on-duty events when the truck is moving

overview

Follow the steps below when:

The truck moves and the Maven app shows an active vehicle connection but no Automatic Duty Status Change (ADSC) events appear on the driver’s log.

Step 1: Confirm adapter power

  1. Use the ADM / Atrack guide (or internal hardware tooling) to verify that the adapter (VDA) is powered on and reporting.

  2. If the adapter does not show power or recent communication:

    • Arrange for a power cycle at a shop or maintenance location.

    • Advise the fleet that the adapter may need replacement if power and connectivity cannot be restored.

If the adapter has power and reports normally, proceed to protocol checks.

Step 2: Refresh the driver’s connection

  1. Ask the driver to leave the vehicle in the Maven app (end the current truck connection).

  2. Close the vehicle connection screen on the tablet.

  3. Start a new connection to the correct truck using the normal vehicle connection flow in the Maven app.

Step 3: Confirm ADSC is working

ADSC works as expected when:

  • The log shows “Automatic Duty Status Change” events, and

  • The driver receives a Driving status automatically after the vehicle:

    • Exceeds 5 mph with standard rules,

    • Or reaches 25 mph while in Yard Move.

To confirm:

  • Coordinate a short test drive with the driver, if possible, and watch for an ADSC drive event shortly after movement begins, or

  • Monitor the driver’s logs in the portal over the next shift to verify that new ADSC events appear.
