We often turn to the engine immediately if we see a GOV to look for the fault. We forget the VEMD is "Vehicle" and "engine" and if 1 of your screens fail you will get a flashing or solid GOV dependant on mod status and so the sensors on the airframe(interface) and leading to the VEMD will also activate a GOV. One I had was for pitot static gen to the VEMD vs what the DECU send and it set the GOV on due a discrepency.
