Code #4 is "system voltage" ... First check the battery and the charging system ...
the battery does seem like it is getting weak can i check the charging system with a multimeter on the battery while it's running and if i can what voltage should i get with it running?
With a volt meter and the bike NOT running battery should show 13.0 -13.2 volts..

With bike running (full charged battery) and headlights on battery should show 15.5 volts at 5000 RPM ..
