General
The engine's shutdown is initiated, when a corresponding shutdown message over the drive train CAN (CAN 4) is pending, e.g. when switching off the engine through the electronic ignition lock (EIS) (S1), through the battery disconnect switch (BESO) control unit (A33) or through the parameterizable special module (PSM) control unit (A22), or through a corresponding operation of the engine start and engine stop button (S600).
Function
As soon as the engine management (MCM) control unit (A4) receives a corresponding shutdown request over the drive train CAN (CAN 4) or if the engine start and engine stop button (S600) is operated with the engine running, it interrupts actuation of the fuel injectors for cylinder 1 to 6 (Y608 to Y613) and actuates the quantity control valve (Y643) electrically so that the fuel supply into the fuel system high pressure pump is interrupted. The fact that no further injection occurs means that the engine comes to a standstill and stops. At engine oil temperatures of less than 70°C the engine brake is also activated to ensure that the engine can "coast down" when shutting down. At engine oil temperatures higher than 70°C it can therefore happen that the engine "vibrates" when shutting down. The quantity control valve (Y643) is actuated electrically for some time after stopping the engine electrically for diagnostic purposes.
