DOT Install

• Install and troubleshoot checks now include a Download step, between the CAN and K-line checks. It starts a tacho download, re-checks on its own and shows the state the unit reached, so a failure tells you where it got to. It stops if the command is stuck. • K-line only passes while a download is running, so doing this first clears K-line failures that were never real faults. The result is saved to install history. • The update prompt now tracks the build actually released to the field. • The app now checks it is up to date. An out-of-date build shows a reminder you can dismiss; one too old to be relied on asks you to update before going further. • Finishing the final tests now keeps you on the unit you just worked on — its settings, a download test and live status are all one tap away, with no need to re-scan the IMEI. • Live status now shows download history (last vehicle-unit and driver-card download) and refreshes every few seconds while you are watching a download land.
