I am unsure what 16 code is but it is not your voltage levels if that is what you mean. In your manual(or the manual of a close friend) 16 will actually correspond to a circuit or system that is having issues. It may or may not be an electrical issue, For example: If you start your bike and let off on the start button to early, bike doesnt start and can actually spin the crank backwards on a compression stroke, well the crank sensor "sees" that and throws a code for cam/crank position....it happened to me....lol
I found a page out of a manual (online search) that says 16 is "Battery positive voltage".
I don't have the manual to look into it deeper. The shop manual I have for my bike does not cover EFI. I guess that's cause the only 95 w/ EFI is the Anniversary Edition Ultra.
Battery voltage falls below the ecm set parameter while running, usually below 9 volts.
Causes: low battery drained at start-up, charging problem, loose cables (pos or neg), bad cables themselves, positive wire to ecm corrodid or loose in connector body. Start eliminating one at a time, good digital VOM is a weapon in problems like these and can monitor your voltage while running.
11 = Throttle position sensor
12 = Barometric pressure sensor
14 = Engine temperature sensor
15 = intake air temp. sensor
16 = battery positive voltage
23 = front injector
24 = front ign. coil
25 = rear ign. coil
32 = rear injector
33 = fuel pump relay
35 = Tachometer (doesn 't apply on FLHR/C-I)
41 = Crankshaft position sensor
42 = camshaft position sensor
44 = bank angle sensor
52, 53, 54, and 55 = ECM problems requiring new ECM
56 = Crank position sensor/Cam position sensor signal error
