isetta Posted May 24, 2017 Share Posted May 24, 2017 depends how the makers programmed it. for some faults it stays on until turned off by plugging in a code reader/reset tool. with some faults it will go off if the system does not detect the same fault occurring within a certain number of times you drive it as the system kind of thinks, it has not happened again for a few days, it must just have been a fluke / one off that the fault was signalled.
