Most likely cause low voltage from battery - causes the computer to fail the system check. Charge the bike or run it for a while and turn it off, turn it on again (letting it re-boot (red triangle to yellow) on switch-on before starting.
Should be fine. Batteries are barely adequate to the task - after a few years they need replacing - consistent ABS faults are a good indication of this even before the starter won't crank the engine.
