Fault code on smart craft

PRO XS 225 SER.#2B737621.
So I’m sitting in my boat and I turn the key on..The gauge lights up as if it’s getting power.My battery selector switch is off ,so I’m surprised there is power to the gauge.I then tried the trim switch and nothing happens.Then the sc1000 gives me a fault code of 4602-23.Turn key off.3 weeks later I turn key on,batt.selector still off, trouble code is still there.Engine has 14 hours and never any codes.Oh and warning horn gives a short beep,then a long beep,about 5 seconds.I assume the smart power from starting battery is supplying the voltage to the key and me trying the trim switch has caused this problem.What does the 4602-23 code mean? How do I clear it? Both my batteries are on a NOCO Genius charger and were at 13.2 volts.Hopefully Don can weigh in on this and bail me out.PLEASE!

FAULT BLOCKER: SYSTEM VOLTAGE

You need to turn your battery switch on. The PCM can wake because CLEAN POWER is provided (as required) via direct connection to the battery. However, MPR voltage is not present because you have the battery switch "off".

In this case, almost certainly caused by a "user error". Turn key off, properly supply battery connection (via switch) and he fault should no longer be actively displayed.
