Hi guys took the bike out this morning only made it 500m before the bike cut out and displayed errors ECU failure, Mtc failure, imobaliser failure,
Now this is the first fault I’ve ever had, a 2020 Ktm 790duke

Been told it could be the battery but got it in charge as we speak! What voltage should I be looking for
Will the faults just clear?
If it doesn’t what else should k be looking at and also does anyone have or recommend a diagnostic tool?

Low battery voltage will do that. If a bike cuts out like this, it may be that the battery is bad altogether and charging it will not help.

Worth trying, though. Once the bike starts, you may want to look at your charging voltage, as well, to see that it is within spec. Also check for current draw.

This may help:
