Description of function:
Starting The engine controller module (A15) is activated via relay K51 by the
ignition lock (S64). During the starting procedure, the engine controller
module (A15) receives the speed signal from the sensor provided on the
camshaft and starts the injection.
Engine monitoring All sensors relevant for operation and monitoring of the engine are
mounted on the engine wiring loom. Only the water level sensor is
connected to the CLAAS wiring loom.
The engine controller module (A15) transmits the signals for displaying
the engine speed, the coolant level and the coolant temperature to the
CAB module (A10) via the CAN bus J1939. The CAN module (A10)
converts this signal to the CLAAS CAN bus, thus allowing display on the
terminal.
Engine diagnosis The number of engine errors occurred and the corresponding error codes
can be displayed in the terminal. Further diagnosis is carried out via the
diagnosis plug in the central terminal compartment, using the Caterpillar
diagnosis tool CAT-ET. The display of error codes can also be activated
by the diagnosis LED (D2) after actuating the rocker switch (U22).
Diesel engine speed
adjustment
The diesel engine speed depends on the position of switch S35 and of the
2nd gear actual value switch (Z83) – see also circuit diagram 42s.
If full throttle speed is selected and the 2nd gear engaged (signal input
A36 / pin 4), the connection between A10/18 and A10/19 inside the
Montana gearshift control module (A36) is cut (pins 10 and 11) – see also
circuit diagram 42s.
The full throttle speed is reduced to road travel speed, depending on the
country version. The maximum speed which can be achieved now can be
configured using the Claas diagnosis system CDS.
