The APU ECU (Electronic Control Unit) mini-flag test is another tool for troubleshooting APU start or run functions.
To see the mini-flags..... press and hold "Lamp Test". After all rows have been sequenced, the code can be read sideways.

Hello Mark, I am programming a maintenance simulation which would include also the Apu Ecu. Would you by chance be able to take a clear high res picture of the full unit straight from the front? With all lights off and all lights on would be the best, if not just off is fine. Thanks!

I'll be back at work tomorrow.
The lights test one row at a time. I'll have to send you a vid for that.

Then just pic with all of em off is perfect. Just straight from the front and with whole computer visible would be perfect as then I’ll make the buttons interactive and make frames with the indicator legends to go over each indicator
