Hi, on M7 Central Diagnostic Panel, I see "ATC Daily Test not ready": it is possible to make this test in order to cancel this warning ?
Here is a talk about it. https://forums.dovetailgames.com/threads/lirr-commuter-m7-and-m9-troubleshooting-advice.81117/
Note that the indication describes the state of the ATC Test itself, not ATC. It will stay "NOT READY" most of the time since while you are driving you can't do the ATC test.
