Hi SeanTT,
EV Promise is right, S56 means warning that the electric motor voltage is low. But it's not serious if it rarely occurs. I would recommend that you check the data on the flash drive under the saddle to see if there are any other errors that did not appear on the display.
In any case, it's good to note that your Victory Empulse TT has not been in operation for a long time and has driven very few miles. This is not very good for the battery, electric motor, transmission and operating fluids. Therefore, it would be good to handle the motorcycle carefully for the next few thousand miles and not test its limits. It is also recommended, at least once every 2 months, to charge the battery to 100% and leave it plugged in for several hours in order to perfectly balance the voltage of all cells and modules. S56 may be the result of poor voltage balance.
The most serious faults are: increased relative humidity in module number 5 (you can check in the data), coolant leakage into the electric motor, gearbox leak around the gear lever, electric motor temperature sensor fault and battery module temperature sensor fault.
Cheers
Karel
