Have anyone seen this error in a while

Tuning a car on the dyno and it started to show this error not sure which version kpro since the owner had the ecu actually mounted. But I think it's a v1

It hapened to me when the batery voltage was low and the time i was loading a file and at the end of the loading the ecu priming the fuel pump the voltage drops even lower so i has this error. I load it again and let the car working to charge the battery and it didnt hapen again
