determines whether the engine is to start, stop, or run. The SYNC MODE switch (called System Mode Switch
(SMS) in electrical descriptions) determines the mode of operation with regards to the paralleling capability. The
PUSH TO STOP EMERGENCY STOP pushbutton (also called Emergency Stop Push Button (ESPB))
immediately stops the engine and should only be used in an emergency. ECM sends alarm signals to the GSC for
any sensors that are directly connected to the ECM.
