it is that the system has detected some kind of fault. It is our experience, that (some times) even if you fix the problem the light may not turn off. For example, if the error somehow simulated a crash sequence the error code will be reflected in the control module and the light will not clear. You can however, with the right type of technology, clear even hard codes written to the module. We do this every day. See reset airbag module link.
