The "OUT OF RANGE" indicates a signal problem. If you can get the engine added, run a signal test to make sure that it is up to par.
Also, if you have the equipment, I'd recommend monitoring the Battery/BCR voltage through the charging port as the engine shuts down to ensure that the process is completed properly. If the battery/BCR voltage drops below 2 volts, that's very close to a power level in which the PS2 electronics will shut down without completing the final steps of the shutdown process.
I have previously posted this information: https://ogrforum.com/...6#182466531934631596
Some additional FYI information about PS2-3v behaviors at different (BCR) voltage levels:
1.6 volts - not enough power to run the sounds and electronics - sounds will cut off early and the board won't completely shut down.
1.9 volts - The DCS remote indicates the Battery as "LOW" The engine sounds go from normal to quiet during track power down.
2.3 volts - The engine sounds go from quiet to normal during commanded start-up.
2.9 volts - Minimum voltage in the BCR needed to complete a successful track power down (with sound), using the BCR indicated below.
3.3 volts - This one is odd. When powering down a DCS track, a "dark & silent" engine won't drop below this voltage level. Not sure if the electronics shut down prematurely or if something else is going on. Any DCS "dark & silent" power down below this voltage results in very little to no voltage drop of the BCR.
4.0 volts - The DCS remote indicates the Battery as "HIGH"
5.1 volts - Maximum volts observed in the BCR after 90 minutes of running.
The DCS remote will indicate Battery "OK" between 1.9 and 3.9 volts.
This was tested with a 5.0v 2.5uF BCR, results with other BCR capacitance or an actual battery will be different.
