If the fault is not present after 1 or 2 starts light will go out, fault code will be stored in ECU for 30-40 starts but light will go out after 1 or 2 so no need to pull fuses or disconnect battery. If the light is on fault is still there and will reappear again pulling fuse or disconnecting battery will not solve it.
