Let us know what you find. My friends 06' Dyna is doing something similar.

The P/N means the P/N of the module/component.

The NONE means no codes in the module you are looking at.

"P"= Powertrain (EFI)
"S" = Security (TSSM)
"SP" = Speedometer.
I'm assuming the last letter was a "t" and you don't have one hence the "no resp"

Unplug the power commander and plug the bikes harness back into the ECM and see if it starts firing. A coil driver in the power commander may be out.

 

Replace battery and clean and tighten battery cable ends on all 4 ends. Go from there. Are you running an aftermarket tuner or flash tune? Is your "parade mode" activated or deactivated? I would also do a push/pull wiggle test on your main harness that plugs into your ECM. Also check all connections while under your seat.
