This fault code means the GSC did not control the engine shutdown. The GSC detected that
engine speed dropped from rated speed to 0 RPM when the GSC has not called for a shutdown.
The GSC has determined that there is no engine speed sensor fault that would explain the engine
shutdown. The engine is disabled from running or starting.
