Binary output: Cooling
The output is closed during the Cooling phase, which takes place after GCB has
been opened before the engine is stopped.
Binary output: Stopping
The output closes when the command to stop the engine has been issued, i.e. the
output Fuel Solenoid has been deactivated. It opens when the engine is fully
stopped. The output also closes if the engine begins to rotate spontaneously.
This output is closed for the whole time of the stopping sequence (regardless of
the repeated opening of the Stop solenoid). It is deactivated immediately when the
engine is considered stopped.
Binary output: Cranking
The output is closed while the engine is cranking. See the following diagrams for
